Cup

Cup (pronounced kuhp)

(1) A small, open container now manufactured usually using ceramics, plastic, glass or metal, typically with a single handle and used as a receptacle from which to drink fluids (tea, coffee, soup etc) and often categorized by design according to their nominal use (tea cup, coffee cup etc); many cups are supplied in sets with a saucer on which the cup sits protecting surfaces from spillage and offer a place on which a stirring spoon may sit.  A cup can be made from glass but may not be a “glass” while a glass made from glass may also have a handle while mugs are essentially cups but called something else.

(2) The bow-like part of a goblet or the like.

(3) A cup with its contents (“a cup of tea” et al).

(4) The quantity contained in a cup (which can be a general reference to any cup or a precisely defined measure).

(5) As a customary unit of measure, a defined unit of capacity frequently used in cooking, the quantum of which varies between (and sometimes within) markets but historically based on a half pint (now usually expressed as 220-250 ml or 14-20 tablespoons).  Measuring cups are available with graduations.

(6) An ornamental bowl, vase, etc especially of precious metal, offered as a prize for a contest (the use of “cup” often persisting even when trophies have been re-designed in a different form); a sporting contest in which a cup (or some other trophy) is awarded to the winner (collective known as the “cup competitions”).

(7) Any of various mixed beverages with one ingredient as a base and historically served from a bowl (claret cup burgundy cup, gin cup, cider cup etc).

(8) In Christianity, the chalice used in the Eucharist (used also of the consecrated wine of the Eucharist).

(9) Something to be partaken of or endured; one's portion, as of joy or suffering.

(10) In many fields, any cup-like utensil, organ, part, cavity etc; anything resembling a cup in shape or function.

(11) In botany, parts such as the flower base of some plants.

(12) In women’s underwear, the two forms containing the breasts in a bra or other garment in which an apparatus with a similar function is integrated (camisoles, bathing suits etc).

(13) In certain sports, a concave protective covering for the male genitalia, reinforced with usually with rigid plastic or metal (in some markets called a “box”, “cup” the common form in North America).

(14) In golf-course construction, the metal receptacle within the hole or the hole itself.

(15) In astronomy, a constellation or a crater.

(16) In pre-modern medicine, as “cupping glass”, a glass vessel from which air can be removed by suction or heat to create a partial vacuum, formerly used in drawing blood to the surface of the skin for slow blood-letting (also called the “artificial leech”).  The concept (cupping) remains in use (though without the blood-letting) in certain beauty treatments popular in East-Asia.

(17) In metalworking, a cylindrical shell closed at one end, especially one produced in the first stages of a deep-drawing operation; to form (tubing, containers etc) by punching hot strip or sheet metal and drawing it through a die.

(18) In mathematics, the cup-like symbol ∪, used to indicate the union of two sets.

(19) As CUP, the international standard (ISO 4217) currency code for the Cuban peso.

(20) In tarot card reading, a suit of the minor arcana or one of the cards from the suit.

(21) In ultimate frisbee competition, a defensive style characterized by a three player near defense cupping the thrower (or those three players).

(22) A flexible concave membrane used temporarily to attach a handle or hook to a flat surface by means of suction (the “suction cup”, the origins of which were in biomimicry (octopodes et al)).

(23) To take or place in, or as in, a cup.

(24) To form into a cuplike shape.

Pre-1000: From the Middle English cuppe & coppe, created by a blending of the Old English cuppe (cup) and the & Old Northumbrian copp (cup, vessel), from the Late Latin cuppa which etymologists list as being of uncertain origin but thought probably a variant of the earlier cūpa (tub, cask, tun, barrel) which may have been cognate with the Sanskrit kupah (hollow, pit, cave), the Greek kype (gap, hole; a kind of ship), the Old Church Slavonic kupu, the Lithuanian kaupas, the Old Norse hufr (ship's hull) and the Old English hyf (beehive).  Etymologists are divided on whether the source of the original Latin was the primitive Indo-European kewp- (a hollow) or the non Indo-European loanword kup- which was borrowed by and from many languages.  The Old English copp was from the Proto-West Germanic kopp (round object, bowl, vessel, knoll, summit, crown of the head), from the Proto-Germanic kuppaz, from the primitive Indo-European gew- (to bend, curve, arch), the source also of the obsolete English cop (top, summit, crown of the head) and the German Kopf (top, head).  The Middle English word evolved also under the influence of the Anglo-Norman cupe & the Old French cope & coupe.  The Late Latin cuppa begat many words meaning “cup” including the Old French coupe, the Saterland Frisian & West Frisian kop, the Old Frisian kopp, the Italian coppa, the Middle Dutch coppe, the Dutch kop & kopje, the Middle Low German kopp, the German Low German Koppke & Köppke, the Danish kop, the Spanish copa and the Swedish kopp.  It was a doublet of coupe, hive and keeve.  The German cognate Kopf now means exclusively “head”.  The first cups doubtlessly were formed by a “cupping” of the hands in order to drink and that action would have been pre-human and an important evolutionary step in the development of the brain.  Later, whatever fell conveniently to hand (sea-shells, the shells of nuts etc) would have been used before drinking vessels came to be fashioned from clay, wood or other materials.  Cup is a noun & verb, cupped & cupping are verbs; the noun plural is cups.

By the late fourteenth century, “cup” had come to be used of just about in the shape of what is now understood as a cup, the sense of “quantity contained in a cup” emerging about the same time.  The sense of a “cup-shaped metal vessel offered as a prize in sport or games” dates from the 1640s, the origin thought to be the traditional ceremonial ritual of celebrating victory by drinking wine or some other alcoholic brew and while it’s speculative, anthropologists have suggested there may be some symbolic link with the idea of “drinking the blood of the vanquished”.  The idea obviously persists, and among the more disgusting versions is drinking from a shoe or boot worn by the victor during the event.  That particular form of podophilic mixology actually has a long history but of late it’s become something of a fetish on the podiums in motor-sport; the term “shoey” was coined in the barbarian nation of Australia.

The origin of the use of “one cup in life” is in the Biblical scripture: And he went a little further, and fell on his face, and prayed, saying, O my Father, if it be possible, let this cup pass from me: nevertheless not as I will, but as thou wilt. (Matthew 26:39 (King James Version (KJV, 1611))).

The word cup appears in many scriptural verses which refer to God's judgment or a time of great suffering, Christ Himself asking James and John if they could "drink the cup" (Matthew 20:22) assigned to Him (by which he meant the suffering that He would soon endure on the cross, experiencing God's judgment for the sins of humanity.  It’s an important theological point, emphasized (Hebrews 4:15) by Jesus seeming to be overwhelmed and saddened by the prospect and awfulness of his crucifixion, praying to God he be spared this fate.  Jesus was, although the son of God, also fully human and few humans wish to suffer humiliation, torture, and death so his prayer was natural but critically, almost at once he submits and resolves to obey the will of the Father.  Whatever his human anguish at what is to come, his absolute commitment is to obeying God.  The idea then is that “suffering is to be endured” was by the fourteenth century expressed in phrases like “the cup of life” and whatever may be the cup, it is “something to be partaken of” because it is the will of God.  In figurative use thus, “one’s cup” is that which is one’s lot to be endured; that which is allotted to one for good and bad.

The daffodil (one of the common names of flowers of the genus Narcissus); as in many flowers, the alternative name for the corona is the cup.

To be in one's cups was to be “intoxicated”, a use dating from the 1610s which may have been a direct development from the mid-fourteenth century Middle English cup-shoten (drunk, drunken).  One’s “cup of tea” is what interests one and came into use in the 1930s of things or concepts although it’s documented from 1908 applying to persons; tellingly, the use of “not my cup of tea” is more common.  The “cup-bearer” was an early fifteenth century job description to describe the “attendant at a feast who conveys wine or other liquor to guests” but a more specialized use was of the court official who carried with him the cups, plates and other utensils to be used by those fearing poisoning (usually royalty or feudal barons).  The phrase “storm in a tea cup” refers to a fuss being made over a trivial matter and is in the same vein as “much ado about nothing”, “tempest in a teapot”, “storm in a teapot”, “lightning in a bottle” and “make a mountain out of a molehill”.

In sport, cups are a popular choice as trophies and they range from small ones in anodised plastic to large, heavy constructions plated in gold or silver.  The America's Cup is contested in yacht racing and, first awarded in 1870, is the oldest international sporting competition still running.  Informally, competitors call it the “Auld Mug”.  The Fédération Internationale de Football Association’s (FIFA, the International Federation of Association Football) World Cup was first contested in 1930 with the tournament since run at four year intervals (skipping 1942 & 1946 because of World War II (1939-1945)).  The name “World Cup” remains although the trophy hasn’t, in the conventional sense of the word, actually been a cup since 1974, the last year the finals were contested by 16 teams (there will be 48 in 2026).  The Webb Ellis Cup is the premier trophy in international rugby and since 1987 tournaments have been run every four years.  The cup is named after English Anglican clergyman William Webb Ellis (1806–1872) who, according to legend, while a pupil at Rugby School, Webb Ellis ignored the rules of the football game he was playing, picking up the ball and running with it “…thereby creating rugby.”  There’s no satisfactory evidence to support the tale and within the game there’s the joke what Webb Ellis invented was rugby's (some say Rugby School's) tradition of theft.

Example of the idiomatic use of cup in the phrase “one’s cups runneth over”: Model Adriana Fenice (b 1994) in 32G (10G or anything between 70-82G in some markets) bra.

The verb use “to cup” was a part of pre-modern medicine by the fourteenth century, describing the use of something cup-like to press against the skin to draw blood closer to the surface prior to “slow blood-letting”.  Medical dictionaries note there were two modes of cupping: one in which the part is scarified and some blood taken away to relieve congestion or inflammation of internal parts (“wet cupping”, or simply “cupping”), the other in which there was no scarification no blood was abstracted (“dry cupping”).  The concept (as “cupping” and without the bleeding) is still used in certain beauty treatments popular in East-Asia.  The cupful (quantity; that a cup holds, contents of a cup) was known in late Old English and persists to this day, the phrase “cup runneth over” is used to refer an over-supply of anything and was from the Hebrew Bible (Psalms:23:5) where the message was “I have more than enough for my needs” and thus a caution against greed, or in the words of Johann Sebastian Bach (1685–1750): Ich habe genug (I have enough) an unfashionable view in a materialist age although one with which Ms Fenice might concur.  Modifiers are appended as required, hyphenated and not including the teacup (circa 1700), the egg-cup (used for making the eating of boiled eggs easier (1773)) and the cupcake (1828).  Cupcakes were “small cakes intended for one” and were an invention of US English, the name derived either from cup-shaped containers in which they were baked or from the small measures of ingredients used.  The slang use to describe an “attractive young woman” was another American innovation from the 1930s.

The use of “cup” in recipes is probably one of the less helpful uses of the word and for those not familiar with the conventions, they were probably baffled and wondering which of the various sized cups they had should be used.  The origin of “cup” as a measure lies in the old English unit which was ½ an imperial pint and thus (10 imperial ounces (284 ml), often later rounded to 300 ml.  Elsewhere, countries did their own thing: In Australia & New Zealand it was set at 250 ml after the conversion to metric measurements in 1973; In the US it was a liquid measure equal to 8 fluid ounces (237 ml which was usually rounded to 240); In Canada it was set at 8 imperial ounces (227 ml and rounded to 250).  The “metric cup” is now a universal 250 ml and for recipes this appears to be the preferred use even in North America.

Bra cups

Example of the idiomatic use of cup in the phrase "storm in a D Cup": Lindsay Lohan in demi-cup bra, from a photoshoot by Terry Richardson (b 1965) for Love magazine, 2012.

If in cooking "cup" has been (just about) standardized around the world, the bra cup, that other use of cup as an expression of volume is bafflingly diverse, anomalies appearing even within a manufacturer's catalogue.  The use of cup in the bra business seems to have begun in the 1930s although among historians of the bra (a surprisingly well populated niche in the discipline of the history of fashion) many differ in detail; the vague consensus seems to be the term was first used in this context in the early 1930s, was wide-spread by 1940 and almost universal by the early 1950s.  The principle of the cup size was compelling simple in that there were two variables (1) the torso and (2) the breasts.  The measurement of the torso was expressed by the bra band size (measured under the bust) in inches (or its metric equivalent) such as 30”, 32”, 34” etc, the graduations between the numbers handled by the fastening mechanism (usually a hook & eye arrangement) allowing a “tight” or “loose” fit so a 32” band could be worn by someone with a torso measurement in a 31-33 inch range.  The cup size range corresponded with the volume of the breast and (in ascending order) these were expressed in letters: A, B, C, D etc so when combined, the products were called 32B, 34C etc.  In theory, the two values worked progressively (up & down: alphabetically & numerically) so the cup size of a 32C was the same as a 30D and a 34B; in the industry, the concept is called "sister sizes", each cup the same dimensions but mounted on a different sized structure (defined by the back-band) and labelled accordingly.  That's the theory and within a manufacturer's single range it may often be true but there is no recognized definition for cup sizes so not only are any two 32Cs from different manufacturers likely to be a slightly different size, nor can it be expected the dimensions of the cup of any 30D will align exactly with that of any other 34B.  It may but it can't be predicted and the expectation should be it will likely "tend towards".

English borrowed the word brassiere from the French brassière, from the Old French braciere (which was originally a lining fitted inside armor which protected the arm, only later becoming a garment), from the Old French brace (arm) although by then it described a chemise (a kind of undershirt) but in the US, brassiere was used from 1893 when the first bras were advertised and from there, use spread.  The three syllables were just too much to survive the onslaught of modernity and the truncated “bra” soon prevailed, being the standard form throughout the English-speaking world by the early 1930s.  Curiously, in French, a bra is a soutien-gorge which translates literally and rather un-romantically as "throat-supporter" although "chest uplifter" is a better translation.  The etymological origin of the modern "bra" lying in a single garment is the reason one buys "a bra" in the same department store from which one might purchase "a pair" of sunglasses or trousers, both of which, centuries ago, began as two separate items.     

Bra size multi-national conversion chart by Fredericks of Hollywood.  Like the footwear business, it seems an industry crying out for an ISO (International Organization for Standardization) but while something buyers might welcome, it seems unlikely industry would share the enthusiasm.  Sizing systems for shoes and bras evolved independently in different regions, based either on local traditions and preferences or just wholly arbitrary choice and there would be much commercial resistance to having to change long-established conventions, something which would necessitate updating labels, packaging & advertising, as well as re-educating initially baffled consumers.  Obviously, that would be costly and therefore lobbied against.  ISO 19407:2015 does provide guidelines for converting shoe sizes between regions but that’s more an acknowledgement of a problem (and a “sort-of”) work-around than a solution and the ISO seems never to have contemplated bras.  Probably, the only way such ISOs could successfully be imposed would be to give industry a long lead-time (perhaps 25-30 years) to permit an orderly and phased world-wide introduction but realistically, few are expecting progress.

Unfortunately the manufacturers complicated things in a number of ways.  Given the A,B,C,D ascending sequence, it would have been reasonable to assume E,F,G & H would follow and in some cases they did but not all, some adopting a double letter convention yielding DD, EE etc but these did not represent fractional sizing-steps between single letters; what was to some manufacturers a DD was an E to others and some were so taken with the idea they added triple lettered sizes so a 32DDD was nominally the equivalent of a 32F from another house.  Some quirks were understandable such as the one which explains the rarity of the I cup, the explanation being the character might be confused with a numeric "1" which, given the syntax of the system, seems improbable but one can see their point.  Although there are a few "I cup" bras, most manufacturers skip the letter and either leave a nominal gap between the "H" & "J" cups or include a "HH" cup in the range.  It's only the descriptions where there's a lacuna, the actual cup sizes on offer still graduated although it can be mystifying because, between manufacturers, the same size can actually be tagged as "H", "I", "HH", "J" or even "GGG" and while that can make in-store shopping merely time-consuming, for on-line shoppers it makes life especially difficult.  

1962 Chrysler 300H (left) and 1963 Chrysler 300J (right).

Chrysler in the US, not wanting the market to think there was a "3001", was in 1963 guided by the same rationale when for the first time since 1956 a letter was skipped in the designation of the 300 “letter series” cars; there’s nothing to suggest the corporation ever pondered a “300HH”.

The BUFF: The new version of the Boeing B-52 Stratofortress (replacing the B-52H) will be the B-52J, not B-52I or B-52HH.   

The US Air Force also opted to skip “I” when allocating a designation for the updated version of the Boeing B-52 Stratofortress (1952-1962 and still in service).  Between the first test flight of the B-52A in 1954 and the B-52H entering service in 1962, the designations B-52B, B-52C, B-52D, B-52E, B-52F & B-52G sequentially had been used but after flirting with whether to use B52J as an interim designation (reflecting the installation of enhanced electronic warfare systems) before finalizing the series as the B-52K after new engines were fitted, in 2024 the USAF announced the new line would be the B-52J and only a temporary internal code would distinguish those not yet re-powered.  Again, the “I” was not used so nobody would think there was a B-521.  Although the avionics, digital displays and ability to carry Hypersonic Attack Cruise Missile (HACM, a scramjet-powered weapon capable exceeding Mach 5) are the most significant changes for the B-52J, visually, it will be the replacement of the old Pratt & Whitney TF33 engines with new Rolls-Royce F130 units which will be most obvious, the F130 promising improvements in fuel efficiency of some 30% as well as reduction in noise and exhaust emissions.  Already in service for 70 years, apparently no retirement date for the B-52 has yet been pencilled-in.  In USAF (US Air Force) slang, the B-52 is the BUFF (the acronym for big ugly fat fellow or big ugly fat fucker depending on who is asking).  From BUFF was derived the companion acronym for the LTV A-7 Corsair II (1965-1984, the last in active service retired in 2014) which was SLUFF (Short Little Ugly Fat Fellow or Short Little Ugly Fat Fucker).

Under the A-B-C-D etc cup-sizing system, a given designation varies in dimensions (and thus volumetric capacity) according to the band size, the cup of a 28A smaller than that of a 32A (which should share size and shape with that used on a 30B).   

The theory: Individual results may vary.

Then there was the band size.  Most countries of course use the metric system so dimensions had to be converted but the convention for those advertised in inches was to use increments of 2 (28, 30, 32 etc) while for metric users it was in jumps of 5 cm (70, 75, 80 etc) which is close but not quite the same (28” = 71.12 cm; 30” = 76.2 cm; 32 = 82.28 cm).  More of a problem was that for the system to work, some math was required because the number from the under-bust measurement didn’t directly translate to the advertised bra size: What the buyer had to do was take the number and add 5 inches (12.7 cm) so if one’s under-bust measurement was 29” (73.7 cm), one (at least in theory) needed something with a 34” band (86.4 cm, the closest in the metric countries being the 85 cm range).  However, if the number was over 33” (83.8 cm), then one added only 3” (7.6 cm).  At that point, one needed to determine the appropriate cup.  This required a further measurement, one taken which represented the bust at its fullest projection, the somewhat misleadingly named “over-bust” number which was actually taken following the nipple line.  Many recommended taking it while wearing a bra but if that was a poor fit, that would hardly be helpful and the ideal method turned out to be (and usually this was necessary only if the volume was above a certain point) holding the breasts in place at the desired location while another did the measuring.  An ideal project then in which to involve one’s boyfriend or girlfriend, the only instructions needed being (1) the tape should rest lightly on the skin and (2) it should straight across the back, parallel to the floor.  The relationship between the over-bust measurement and the band size indicated the needed cup size: if the difference is 1” (2.54 cm) then it dictates an A cup; 2” (5.08 cm) and it’s a B cup and so on.  In many cases the simple under/over equation will work but not in all and some authorities have added additional measurements to be taken while in different positions, the 6 listed including lying flat on one's back and leaning forward so the breasts are perpendicular to the ground.  Definitely, the more dimensions which are taken, the more this seems a job for two.  

The math of cup sizes.

In practice it transpired the human body wasn’t so accommodating of production line rationalization but the system worked well enough for it to have endured for decades although only a percentage of women find an ideal fit without the help of an in-store fitter.  Quite what that number is depends on who is asked but it’s clear it’s a long way short of 100%.  The outcome for bra wearers wasn’t helped by the lack of standardization in either the labeling or the technical specification of the cup size.  The inches vs centimetres thing was manageable but even in some countries which had long switched to the metric system, bras sizes were often expressed in inches (a similar aberration to the (almost) universal use of inches for certain products including the wheels used on cars and computer monitors) and because of the internationalized nature of the market with so much imported product, in many countries, both sizing regimes simultaneously were on sale, often in the same shop.  Helpfully, many displayed wall charts with conversion tables.  For some reason, in Australia and New Zealand, the decision was taken to use the dress sizing standard used in the antipodes (8 = 30”, 10 = 32” etc), thus bra sizes like 8C, 10D etc which local users presumably adapted to but it seems a needless complication.  Additionally, regardless of what country one was in, there was no guarantee a given size from one manufacturer would exactly align with that from another and in England, a comparison by a consumer organization revealed band and cup size differences existed in stated sizes even between various styles produced by the same manufacturer; not all 32Ds were created equal.  Given that, it seems obvious it’s best to seek the assistance of a fitter but in the internet age, customers found capitalism offered a handy on-line, home delivered alternative, the trick being to order half a dozen bras of slightly different declared sizes (eg 32C, 30D, 32E etc), the ones not quite right being able to returned for credit at no cost, the site paying all the P&H (postage & handling).  That approach has attracted much criticism because of the environmental impact and it’s a significant cost to the distributor and some have now moved to restrict the practice.

Details of fifteenth century bras in Linen from Austria.

Although it wasn’t until well into the twentieth century the idea of cup sized was codified (though to this day not standardized), the concept turned out to be ancient, something confirmed in 2008 when, as part of her PhD research, Austrian anthropologist Beatrix Nutz was undertaking at the University of Innsbruck in Austria, retrieved from the dirt, wood and straw (all discarded stuff apparent used as insulation) of centuries ago in the foundations of an Austrian castle, four linen bras among some 4000 textile fragments.  What was striking was the medieval garment was the similarity to the version first patented in the United States in 1914 something perhaps unsurprising as there really is only one way to achieve the functional effect desired if a minimalist approach is pursued and that’s what was done, a few centuries apart.

Fifteenth century "longline" bra in Linen from Austria, the midriff-enveloping fabric originally extending beneath the cups.

The detailing on the garments would be familiar to those bra shopping in the twenty-first century, the lower ends decorated with finger-loop-laces, sown on with lace-stitches, resulting some simple needle-lace decoration.  There’s structural overlap too, one of the unearthed bras in the style of the “longline” bras which first became popular in the 1930s, both representing the practical expedient of combining a type of corset with a bra.  Clearly, while not necessarily something with wide commercial availability, garments in the style of the linen bras must have been well-known (at least in certain circles because in French texts as early as 1315 CE there are mentions of the “breast bags” or “shirts with bags” women used to support and restrain their breasts and one disapproving author called them “indecent” although it seems his objection was to “breasts too large” rather than the pre-modern lingerie used to minimize their appearance and the longest known surviving fragment in this vein is a verse from fifteenth century Vienna:

Ir manche macht zwen tuttenseck
Damit so snurt sie umb die eck,
Das sie anschau ein ieder knab,
Wie sie hübsche tütlein hab;
Aber welcher sie zu groß sein,
Die macht enge secklein,
Das man icht sag in der stat,
Das sie so groß tutten hab.

Translation:

Many a woman makes two bags for the breasts,
with them she roams the streets,
so that all the guys look at her,
and see what beautiful breasts she has got;
But whose breasts are too large,
makes tight pouches,
so it is not told in the city
that she has such big breasts.

Nursing bras use specialized cups: Lindsay Lohan inspects the apparatus in Labor Pains (2009).

The most obvious specialized cup is that used with nursing bras which feature an arrangement whereby most of the cup’s fabric can be semi-separated from the superstructure, enabling breast-feeding without the need to remove the whole garment.  Among bra manufacturers, there are different implementations by which the functionality of a nursing bra's apparatus is achieved and presumably chest-feeders (the preferred term among the woke to describe those who used to be called “breast-feeding women”) choose whichever best suits them; it may simply be that for manufacturers the production-line rationalization achieved by being able to adapt the specialized cups to the structures used for conventional bras is compelling, dictating the designs.  Which chest-feeders choose is of some significance given how often heard is the complaint the process is “tiring”.  To those who will never be chest-feeders it sounds more a pleasant and diverting relaxation rather than anything tiring but they all say it so it must be true.

The "push-up" bra (the best-known of which is the "Wonderbra") lives up to its name by using strategically placed padding which has the effect of "pushing up" the breast tissue (it has nowhere else to go), creating the visual effect of something bigger and higher.  Most padding is purely functional but there are also novelty items such as the one above which is variant of the "hand bra", also a thing.  

The cupless: A "special purpose" bra available in S, M, L & XL.

Other variations include the demi-cup (also called the half-cup ("semi-cup" not a recognized term)), the bullet cup, the adhesive cup (an enlarged & shaped adaptation of the so-called "tit-tape" technology), the padded cup and the seemingly paradoxical cupless (or open-cup), the last a niche market.  Those wanting to have "their cake and eat it too" who like to go braless while enjoying the benefit of some support can buy clothes with a "built-in bra" or a "shelf-bra" although the law of physics continue to operate and beyond a certain size (and more to the point: weight), these things simply: "don't work".  The cups of a "push-up bra" include thick padding towards the bottom of the structure, this having the effect of "pushing up" the breast tissue, lending things a higher, fuller look.  There are degrees to which this can be implemented: the more the padding, the greater the effect.

Bra cups can even be virtualized.  The technique called Trompe-l'œil (from the French and literally “trick the eye” describes an optical illusion created by rendering on a two-dimensional surface something which appears as a three-dimensional object and the trick had been around for millennia when first the term was used in 1800 by French artist Louis-Léopold Boilly (1761-1845) for a painting he exhibited in the Paris Salon.  While it wasn’t for a few decades trompe-l'œil (usually in English as trompe l'oeil) was accepted by the academy as a legitimate part of high-art, architects and interior decorators continued to exploit the possibilities and the term entered their lexicons.  It has of course for years also been used in the prints on T-shirts but of late this has extended to depictions of underwear.  For most of the twentieth century, the sight of an exposed bra strap was a social faux pas, Vogue and other dictators of fashion publishing helpful tips recommending (for the well-organized) sewing on Velcro strips and (for everyone else) the industry’s DLR (device of last resort): the safety pin.  By the 1980s things had changed and the bra emerged as a fashion piece which might in part (or even in whole) be displayed.  It’s a look which waxes and wanes in popularity but one which has never gone away although it’s one of those things where ageism remains acceptable: beyond a certain age, it shouldn’t be used.  Now, fashion houses are promoting trompe l'oeil bras, knickers and other underwear printed on T-shirts, one attraction being it’s possible to create depictions of garments with an intricacy and delicacy not possible IRL (in real life).

There are also bras for those who have lost a breast, the cups of which are “double-skinned” in that they feature internal “pockets” into which a prosthetic breast form (a prosthesis) can be inserted.  Those who have had a unilateral (or single) mastectomy (the surgical amputation of one breast) can choose a cup size to match the remaining while those who have lost both (a bilateral or double mastectomy) can adopt whatever size they prefer.  There are now even single cup bras for those who have lost one breast but opt not to use a prosthetic, an approach which reflects both an aesthetic choice and a reaction against what is described in the US as the “medical-industrial complex”, the point being that women who have undergone a mastectomy should not be subject to pressure either to use a prosthetic or agree to surgical reconstruction (a lucrative procedure for the industry).  This has now emerged as a form of advocacy called the “going flat” movement which has a focus not only on available fashions but also the need for a protocol under which, if women request an AFC (aesthetic flat closure, a surgical closure (sewing up) in which the “surplus” skin (often preserved to accommodate a future reconstructive procedure) is removed and the chest rendered essentially “flat” ), that is what must be provided.  The medical industry has argued the AFC can preclude a satisfactory cosmetic outcome in reconstruction if a woman “changes her mind”  but the movement insists it's an example of how the “informed consent” of women is not being respected.  Essentially, what the movement seems to be arguing is the request for an AFC should be understood as an example of the legal principle of VAR (voluntary assumption of risk).  The attitude of surgeons who decline to perform an AFC is described by the movement as the “flat refusal”.

1325-1375: From the Middle English triple (there was also þripell), from the Old French triple or the Medieval Latin triplare (to triple) from the Latin triplus (threefold, triple), from the primitive Indo-European tréyes.  Triple is a noun, verb & adjective, tripled is a verb, tripling is a noun & verb, triply is an adverb and triplet is a noun; the noun plural is triples.

In English, the Latinate multiplier “triple” is but one of many ways the value three (3) is in some way expressed or applied.  “Three” is the highest value, single digit cardinal number, as an ordinal it’s “third” (the Latinate ordinal is “tertiary”), the adverbial form is “thrice” (or the more mundane “three times”, as a multiplier the term is “threefold” (also as “three-fold”), the distributive is “triply”, the collective “tripartite”, “trio” or “threesome” (ménage à trois a popular version which has tended to limit the utility of “threesome” for other purposes), the multiuse collective “triplet”, the Greek or Latinate collective “triad”, the collective prefix (from both Latin & Ancient Greek (the latter also had “trito”)) was “tri”, the fractional expression is “third” (the Latinate fractional prefix was “trient-”, the elemental “thrin” & “triplet” and a period of three years is a triennium.  However, while there are weeks, fortnights & months, there’s no accepted term which express a measure of 21 days although three months is often described as “a quarter” although in the context of the nine month gestation associated with human pregnancy, the three month blocks are "trimesters" (first, second & third).  The use in obstetrics extended to education and in systems where academic years exist in four semesters (or terms), there is also the "fourth trimester".

Originally an adjective, the noun emerged in the early fifteenth century.  The use in baseball dates from 1880 while the various uses of triple-deck, triple-decker etc (a development of the earlier double-decker) for cakes, sandwiches, bunk-beds etc all came into use in the early 1940s.  Triple-barrel carburetors were rare but did exist, Porsche for example using them on their flat sixes.  Rugby Union in 1883 was the first to use “triple crown”, awarded in the UK to the side which won the three “home countries” (England, Ireland, Scotland & Wales) matches.  That was based on the use of the papal triple crown (sometimes as triple tiara) then used for the coronation of the Roman Catholic Pope and was later picked up in US thoroughbred racing: The Kentucky Derby, the Preakness Stakes, and the Belmont Stakes comprise the Triple Crown which was first officially awarded in 1919 although the term didn’t become widely used until the 1930s.  In motorsport, despite the popular perception, it’s never been an official award and many branches of the sport have their own triple crowns, most barely known outside of the small circle of their cognoscenti.  The three events which comprised the classic triple crown were (1) the Indianapolis 500 (first run in 1911), the 24 Hours of Le Mans (first run in 1923) and the Monaco Grand Prix (first run in 1929) and it’s been achieved only once.  That was by Graham Hill (1929–1975) who completed the set at Le Mans in 1972 and although he and others have suggested the Formula One World Championship should be included instead of the Monaco Grand Prix, the original arrangement seems still the accepted triple crown.

The Triple Alliance and Triple Entente were diplomatic arrangements formed in Europe in the decades prior to the First World War (1914-1918).  The Triple Alliance between Germany, Austria-Hungary & Italy was signed in 1882 as a defensive system directed entirely against France.  It was an integral part of the series of treaties and agreements variously negotiated or imposed by Otto von Bismarck (1815-1989; chancellor of the German Empire (the "Second Reich") 1871-1890) and needs to be understood in the way it interacted with other cogs in the Bismarck machine.  That machine, a collection of inter-locking treaties and agreements (some of them secret) worked to further the interests of (1) the German Empire and (2) a general peace in Europe and was a good device in Bismarck’s capable hands but it proved lethal when less competent practitioners (who didn’t fully understand the implications) inherited the tool.  The Triple Entente was between France, Russia and the UK and was formed in 1907; in the narrow technical sense it was not a formal military alliance but an “understanding” between the three to counter the growing power of Germany and the Triple Alliance.  The Ottoman Empire and Bulgaria would become attached to the Triple Alliance with the onset of war although Italy initially remained neutral before (in what would continue to be an Italian tradition) switching sided in 1915 to join the Alliance.  Both the Alliance and the Entente played their parts in the escalating tensions which culminated in the outbreak of hostilities which would trigger the chain reaction of declarations of war.  Had Bismarck still been in Berlin, it’s unlikely things would have been allowed to assume their own momentum.

The word is used also as a modifier as required such as triple-barreled (used with three-element surnames and in various manufactured items but best known in shotguns), triple-headed (again widely used but probably still most associated with creatures from mythology, tripledemic (a term used in public health and epidemiology to describe the simultaneous outbreak of three epidemics or pandemics), triple fault (in computing a third (and fatal) error instance in a CPU attempting a graceful recovery from a double fault, triple jump (an athletic (track & field) event involving three different types of jump), triple goddess (a female deity who is either three goddesses in one or one who is triune (both three and one at the same time) and triple X syndrome (a chromosomal variation characterized by the presence of an extra X chromosome in each cell of a human female).

The papal triple tiara

Pius XII (1876-1958; pope 1939-1958) in the papal triple tiara, at his coronation, 12 March, 1939.

The papal triple tiara is a crown which has been worn by popes of the Roman Catholic Church since the eighth century.  Traditionally it was worn for their coronation but no pontiff has been so crowned since Paul VI (1897-1978; pope 1963-1978) in 1963 and he abandoned its use after the Second Vatican Council (Vatican II, 1962-1965).  The name tiara refers to the entire headgear and it has used a three-tiered form since a third crown was added during the Avignon Papacy (1309–1378).  It's also referred to as the triregnum, triregno or Triple Crown.  In a piece of one- (or perhaps four-) upmanship, Suleiman I (Süleyman the Magnificent, 1494-1566, Sultan of the Ottoman Empire 1520-1566) commissioned from Venice a four tier helmet to show, in addition to the authority claimed by popes, he could add the symbol of his imperial power.  Often put on display as the centrepiece of Ottoman regalia to impress visitors, there's no documentary evidence the sultan ever wore the four layer tiara, crowns not part of the tradition and, fashioned from gold and gemstones, it would anyway have been extraordinarily heavy.

A representation of the triregnum combined with two crossed keys of Saint Peter continues to be used as a symbol of the papacy and appears on papal documents, buildings and insignia.  Remarkably, there’s no certainty about what the three crowns symbolize.  Some modern historians link it to the threefold authority of the pope, (1) universal pastor, (2) universal ecclesiastical jurisdiction and (3) temporal power.  Others, including many biblical scholars, interpret the three tiers as meaning (1) father of princes and kings, (2) ruler of the world and (3) vicar of Christ on Earth, a theory lent credence by the words once used when popes were crowned:  Accipe tiaram tribus coronis ornatam, et scias te esse patrem principum et regum, rectorem orbis in terra vicarium Salvatoris nostri Jesu Christi, cui est honor et gloria in saecula saeculorum (Receive the tiara adorned with three crowns and know that thou art father of princes and kings, ruler of the world, vicar on earth of our Savior Jesus Christ, to whom is honor and glory for ever and ever).

Documents in the Vatican Archive suggest by 1130 the papal tiara had been modified to become a conventional (and temporal) symbol of sovereignty over the Papal States.  In 1301 during a dispute with Philip IV (Philip the Fair, 1268–1314, King of France 1285-1314), Boniface VIII (circa 1230–1303; pope 1294-1303) added a second layer to represent a pope’s spiritual authority being superior to an earthly king’s civil domain.  It was Benedict XII (1285–1342; pope 1334-1342 (as the third Avignon pope)) who in 1342 who added the third, said to symbolize the pope’s moral authority over all civil monarchs, and to reaffirm Avignon’s possession.  A changing world and the loss of the Papal States deprived the triple crown of temporal meaning but the silver tiara with the three golden crowns remained to represent the three powers of the Supreme Pontiff: Sacred Order, Jurisdiction and Magisterium.

Not since 1963 has a pope worn the triple crown.  Then, the newly-elected Paul VI, at the end of his coronation, took the tiara from his head and, in what was said to be a display of humility, placed it on the altar.  In a practical expression of that humility, the tiara was auctioned; the money raised used for missionary work in Africa although, keeping things in house, the winning bidder was the Archdiocese of New York.  Popes Benedict XVI (1927–2022; pope 2005-2013, pope emeritus 2013-2022) and Francis (b 1936; pope since 2013) received tiaras as gifts but neither wore them.  Benedict’s, in a nice ecumenical touch, was made by Bulgarian craftsmen from the Orthodox Church in Sofia, a gesture in the name of Christian unity.  Benedict would have appreciated that, having always kept a candle burning in the window to tempt home the wandering daughter who ran off to Constantinople.

The Mercedes-Benz triple rotor Wankel

The original (although there was a prototype rendered in the tradition of functional brutalism) Mercedes-Benz C111 with triple rotor Wankel engine (1969).

Triple cylinder engines in cars were something of a niche in the early post war years but of late they’ve achieve a new popularity, improvements in electronics and combustion chamber design meaning three cylinders can now achieve what once required four and even with an equivalent displacement their efficiency is inherently greater because of the reduction in internal friction.  Obviously compact, they’ve proved an ideal power-plant in hybrid vehicles.  One quirky triple was the Mercedes-Benz C111 which first appeared in 1969 with a 1.8 litre (110 cubic inch) three-rotor Wankel engine, something then thought to have a great future; it seemed a good idea at the time.  The C111, although produced in a small run and finished in some cases to production car standards was only ever a test bed, not only for the doomed rotary engine but also developments in suspension design, anti-lock braking (ABS; Anti-Bloc System) and safety engineering.  The gullwing body really was designed by an Italian-born stylist but so long had he been in Germany that Teutonic ways had entered his soul so the C111 was less lovely than what might have emerged from a studio in Turin but at the time it still caused a stir, even though finished in what the factory called “safety orange”, their standard high-visibility paint for prototypes and test-beds.  Later versions were fitted with a four-rotor Wankel, a variety of diesels and even a 4.8 litre (292 cubic inch) V8, the fastest of the rotaries said to be capable of 300 km/h (188 mph) while the V8 version (C111-II-D) in 1976 set a new closed-course record on the Nardò Ring in Italy, clocking in at 403.978 km/h (251.815 mph).

Triple carburetors

1966 Ferrari 275 GTB/C (Gran Turismo Berlinetta Competizione (denoting a grand touring coupé built to competition-specification)).

When submitting to the Fédération Internationale de l'Automobile (the FIA; the International Automobile Federation) the application to homologate the 275 GTB/C for sports car racing, there was some glitch in the factory’s administrative processes because the document certifying the existence of a six-carburetor option for the 275 GTB wasn’t part of the paperwork enclosed.  That meant the 275 GTB/C could appear on the grid only with triple carburetors so to compensate, Ferrari had Weber produce a run of 40 DF13 units which in addition to their higher flow-rate featured lightweight magnesium bodies instead of the aluminium housing and were distinguished also by the distinctive, rearward-facing inlet trumpets.  As might be expected, original Weber 40 DF13s now command a premium price.  Twelve 275 GTB/Cs were built and the model was a turning point in being the last Ferrari built for racing to use the classic Borrani wire wheels.  Such had been the advances in tyre technology that by 1966 the grip generated transferred stresses so acute that in extreme conditions the spokes could break, a tendency exacerbated by the wheels’ additional width (7 inch front 7½ rear); there were accidents.  Such was the concern the two 275 GTB/Cs built as road cars were factory-fitted with aluminum-alloy wheels although the lovely Borranis continued to be made available for the later and much heavier 365 GTB/4 (Daytona, 1968-1973) and 365 GTC/4 (1971-1972), the factory cautioning they were suitable only for road use.  In truth, using a 275 GTB/C on the road was a dubious proposition because, as a weight-saving measure, the body panels had been fabricated in thin 20-gauge aluminium; about half the thickness of the metal used for the road cars, it could be dented just by being touched and the dainty bumperettes (which offered at least some protection on the other variants of the 275 GTB) were wholly fake and merely affixed to the panels with no underlying structure.

The last in the XK series (XK120 (1948-1954), XK140 (1954-1957) & XK150 (1957-1961)), the Jaguar XK150 debuted with a version of the twin carburetor 3.4 litre XK-Six used since 1948.  Increased weight had blunted the XK150's performance, something not wholly off-set by the slight increase in power coaxed from the engine and in 1958 the option of an "S" specification was made available as the XK150S, restoring the pace of the earlier cars, the raised output achieved with a revised cylinder head and triple carburettors (seen earlier in the 1950s on the C-Type, D-Type & XKSS).  The final and fastest of the species was the 3.8 litre version of the XK150S, introduced in 1960; the engine in essentially this configuration would later be shared with the early E-Types (XKE) and Mark X, the triple carburetor arrangement carried when the 4.2 litre versions were released in 1964.  The triple carburetor engines were in 1968 withdrawn from the US market because the anti-emission regulations made the cost of certification prohibitive although, while in North America buyers had to be content with twin-carburetor units, the triples continued for RoW (rest of the world) vehicles exported to other places or sold in the home market.  When the last of the six-cylinder E-Types was made in 1971, that was the end of the line for the triple carburettor Jaguar.  It is however misleading to suggest the XK150S, E-Type and Mark X/420G were the only series-production Jaguars with triple carburetors because on some cars during the 1950s & 1960s, the factory fitted a smaller electromagnetically controlled “auxiliary carburetor” which augmented the main pair, making starting easier.  The unusual arrangement acted as a choke but it was a complicated solution to a simple problem and, while performing faultlessly in testing, in the real world with gas (petrol) of varying quality and in different climatic conditions, it sometimes proved troublesome and there were owners who gave up and installed a conventional choke.

The early carburetors were all single throat (later also as “choke” or “barrel”) device and almost all were gravity-fed; it wasn’t until the 1930s the first two-barrel (then called a “duplex”) units appeared.  That design was such an advance because the duplexing allowed “fuel separation” manifolds which more accurately sent the mixture to the most distant cylinders; the adoption if this technology in 1934 allowed the output of Ford’s then new “flathead” V8 to rise from 60 to 85 horsepower (HP).  Buick in 1941 created what was, in effect, the first four-barrel system by installing two two-barrel units, the second becoming active only when the throttle had been opened far enough to operate the progressive linkage.  The advantage of that was economy of operation because the additional fuel-burn happened only on demand; it was an approach Detroit would use until 1971.  Four-barrel carburettors which operated on the same model appeared at scale in the 1950 and became an industry standard, some even installed in pairs on the high-performance vehicles.  Ideal in many ways for the V8 layout, the problem for the manufacturers was the engines grew at a much greater rate than the carburetors and while the dual four-barrel configuration was suited to some, a better compromise for many was to use triple two-barrels.  Pontiac and Oldsmobile chose that path in 1957 and Chevrolet and Cadillac followed in 1958.  Ford flirted only briefly with the triple two-barrel before switching for a few years to dual four barrels for their high performance V8s, their first venture in 1958 when three were bolted onto the big, heavy 430 cubic inch (7.0 litre) MEL V8 although in that form it appeared only on one Mercury for that single season.  As higher-volume four-barrel carburetors became widely available, the rationale for the triple option faded and Chevrolet ceased use for all but the full-sized line and the Corvette; the last triple carburetor corvettes were built in 1969.  Chrysler was last to adopt the idea and the last to offer it, Trans-Am themed 340 cubic inch (5.5 litre) Plymouth ‘Cudas and Dodge Challengers made in 1970 while the 440 cubic inch (7.2 litre) (advertised variously as “Six Pack” by Dodge and “Six Barrel” by Plymouth) was available in several models between 1969-1971 (it's said six 1972 cars were so configured) although its last appearance was in the Jensen SP, the last of which was built in 1973.  Jensen's experiment had at the time seemed a good idea because, with the engines outlawed in the US, they obtained the surplus stock at an attractive price but in the Interceptor's smaller engine bay and equipped with air-conditioning (something Chrysler never coupled with the triple carburetor engines), the SP proved troublesome and production was terminated, Jensen not taking up to option to buy the remaining stock,

Of taillights and exhaust tips 

1957 DeSoto Adventurer Convertible.

DeSoto's signature triple stacked taillights were a footnote in Detroit's macropterous era of the late 1950s, the style making possible the distinctive vertical arrangement.  Chevrolet would for years make triple taillights a trademark of their more expensive lines (although, apart from the odd special built for the show circuit, they resisted the temptation to add a third to the Corvette (the additional rear apertures on the abortive 1963 Corvette Grand Sport (GS) were for air extraction)) but they appeared always in a less memorable horizontal array.  DeSoto's motif was Chrysler's most successful use of the fins but it wasn't enough to save the brand  which was crowded out of the mid-priced market, not only by competition from General Motors (GM) and Ford but also by intra-corporate cannibalization, squeezed from below by Dodge and from above by Chrysler's new Newport line.  Demand for DeSotos collapsed and that 3034 1961 models were built in late 1960 happened only to use up the large inventory of the few parts still exclusive to the brand.  The last of the line, heavily discounted, were not sold until well into 1961 by which time DeSoto was a single-model range and any loyal customer unable to be supplied with one after stocks were exhausted was rewarded instead with a similarly configured Chrysler Newport, a notch up the corporate hierarchy.  The 47-day production run of the 1961 DeSotos was short but it was longer than that of Ford's doomed 1960 Esdel, 2864 of which left the production line over 34 days late in 1959. 

More sharing of stuff than before: 1960 DeSoto Fireflite four-door hardtop (left) and 1960 Chrysler New Yorker four-door hardtop (right).

Note the New Yorker's larger rear window.  Remarkably (by today's standards), the Chryslers of this generation offered two different designs of rear glass, the extra surface-area described in the brochures as the “Extra-large rear window” and it was a time when such flourishes were a matter purely for designers and accountants whereas now it would require a separate programme crash-testing several vehicles.  The big glass was standard on all two-door hardtops & New Yorker four-door hardtops and optional at various times on the Saratoga, Newport and Windsor four-door hardtops.

1961 Chrysler brochure (page 7).

The phrase "EXTRA-LARGE REAR WINDOW" really did appear (capitalized) in the brochures and the simplicity in the description wasn't always typical of the advertising copy of an era during which words like "vista", "panoramic" or "dioramic" might have been expected when extolling the virtues of having more glass.  In the same (1961) brochure, the plain-speaking language may be compared with "FLIGHT-SWEEP DECK LID", used to describe the fake spare tyre cover the agency further explained was a "smooth sculptured circle" which added "a distinctive finishing touch".  In the wild, universally, the "flight sweep deck lid" was referred to as "the toilet seat".  "Flight-Sweep" was an allusion to a pair of concept-cars Chrysler sent around the show circuit in 1955 and they genuinely did have the spare tyre housed under the mounting although the complexity of the assembly would have seen it vetoed by the accountants as too expensive for mass-production.  When "Flight Sweep" was used as an advertising hook for the 1956 range, while some of the styling cues from the show cars did appear the "toilet seat" did not but it was a feature (many suggesting, even then, a blemish) between 1957-1960 when it was fitted as standard on some of the higher-priced lines and an option on others.  There were buyers who chose the option so the "toilet seat look" must have had some appeal.   

By 1959 the writing was on the wall for the once popular DeSoto and the 1960 range would prove its swansong, the last of the breed barely modified Chryslers and the only real hint of the past was the taillight's triple frets.  On the DeSoto the ridges were a modest attempt to retain brand identity but in optics such things have a purpose and are known as “Fresnel lenses” or “Fresnel ribs”, the name from French civil engineer Augustin-Jean Fresnel (1788–1827), remembered for his research into optics which led eventually to the near-unanimous acceptance of the nature of light being a wave (he was half-right but light was later proved to possess a wave-particle duality).  His more enduring Fresnel lens used the catadioptric (reflective/refractive) principle and what the “stepped” design did was extend the reach of lighthouse beams, doubtlessly saving the lives of many seafarers.  Fresnel’s invention was a refinement of the dioptric (refractive) stepped lens, a concept first published by the French cosmologist and mathematician Georges-Louis Leclerc, Comte de Buffon (1707-1788) and Fresnel’s enhancements better distributed and directed the light, improving visibility from longer distances and a greater range of angles.

By 1960 (left) the DeSoto's taillights were a shadow of the way the triple-stack motif had been defined in 1959 (right): This juxtaposition is DeSoto Red Tail Lights in Black and White by Paul Ward.  Many designers probably will prefer the later interpretation but there's a charm to the triple stack.

Unexpectedly, in the early 1970s, Ferrari had a flirtation with triple taillights and they doubled-down for the 365 GT4 BB (better known as the Berlinetta Boxer), adding a pair of triple tail-pipe apparatuses (thus a count of six rather than the usual four) for the 4.4 litre Flat-12.  Before the decade was out it must have been decided four of either was enough and the factory decided for a while (mostly) to stick to the classics: as designs like the Dino 206 GT illustrate, less can be more.  Since the BB however, Ferraris have also appeared with two and three tailpipes (some in the 1970s had but one) and in the twenty-first century many cars come with just a minimalist pair of taillights.  Ascetically, no arrangement works as well as the traditional template: four lights, four pipes.

The fetish of motorcycle exhaust systems

1980 Laverda Jota 1000 (3-into-2, far left), 1973 Suzuki GT750 "Water Buffalo" (3-into-4, centre left), 1972 Kawasaki 750 Mach IV (H2) (3-into-3, centre right) and 2017 MV-Augusta Dragster 800Rc (3-into-3, far right).

Triple cylinder engines have been a feature of motorcycle engines for decades and different manufacturers have taken various approaches to the exhaust systems, an item which exerts upon riders a special fascination.  It’s not unusual to fit single systems (3-into-one) but there are also some which “siamesed” the central header pipe, the derived pair joining the two outer pipes to duct into two mufflers.  Unusually, Suzuki for a while offered 380, 550 & 750 cm³ machines with 3-into-4 systems, the central header again “siamesed” the central header but had the novelty of terminating the two pipes in separate mufflers thereby emulating the appearance of a four-cylinder machine.  It was a curious arrangement which Suzuki abandoned and other manufacturers choose not to follow (although there had been after-market suppliers which concocted 2-into-4 systems which exchanged the "advantage" of "the look" for the drawback of additional weight and needless complexity).  Greatly at the time, Suzuki must have valued symmetry.

Somewhat earlier, asymmetry hadn’t frightened Kawasaki which used pragmatic 3-into-3 engineering for their range (250, 350, 400, 500 & 750 cm³) of charismatic, highly strung two-strokes, one pipe to the left, two to the right and it was a distinctive feature which, although sometimes seen on the track, remains rare on the road.  In the same era, Triumph on their X75 Hurricane took 3-into-3 asymmetry to its logical conclusion, its three pipes arranged in a radically upswept stack on the right.  It looked dramatic and was much admired but didn’t catch on although there’s the odd revival, the Italian house MV-Augusta engineering a particularly aggressive interpretation on their Dragster 800Rc.

So there have been triple-cylinder motorcycles with exhaust systems configured as 3-into-1, 3-into-2, 3-into-3 & 3-into-4 but the early versions of the Trident and BSA Rocket 3 (1968-1975) offered a unique take on things with a design which had the three headers ducted into two mufflers, each of which terminated with three exhaust stubs so it can be described as a 3-into-2-into-6 which seems one layer of complication too many.  The styling on the early Trident and Rocket wasn’t well received and was revised for 1971.  Neither motorcycle was a commercial success because they arrived too late; had the pair been released in 1966 as was planned, things might have been better because genuinely they were fast and offered a level of refinement beyond the parallel twins which for years had been a mainstay of the British industry.  As it was, within weeks of their debut, Honda’s epoch-making 750-Four was on the market, a generation (or more) advanced compared with the competition and when the Kawasaki 900 later followed, even the (slight) performance advantage enjoyed by the British triples vanished.

2022 Triumph Rocket 3 GT in triple black.

When Triumph announced the Rocket 3 in 2019, most attention was on the numbers, the 2458 cm³ (150 cubic inch) triple being the largest displacement engine available in a motorcycle and the (163 ft-lb) (221 N⋅m) torque generated also industry leading, topping even the big Ducatis and the straight-six BMW.  Triumph since 2004 been at the top of the displacement tree with the Rocket III’s 2294 cm³ (140 cubic inch) engine and the updated model was very much a modernization exercise, something which may account for the decision to switch from the traditional Roman numerals to a digitally compliant “3”.  Being a triple there were of course options for how to handle the exhaust ducting and for the GT model Triumph opted for the asymmetric on the model of the old Kawasaki two-strokes rather than reprise its own X-75 Hurricane of nearly half a century earlier.  Unlike Kawasaki, Triumph didn’t make asymmetry a signature feature, choosing to route the third exhaust, almost inconspicuously, just under the swing-arm on the left side, a curious juxtaposition with the visual statement of intent made by the two on the right.  Doubtlessly the engineering behind the decision was sound and to add a bit of high-tech bling, some Rocket 3’s had carbon-fibre exhaust tips and most conspicuously they were carbon-fibre.
