Nail

Nail (pronounced neyl)

(1) A slender, typically rod-shaped rigid piece of metal, usually in many lengths and thicknesses, having (usually) one end pointed and the other (usually) enlarged or flattened, and used for hammering into or through wood, concrete or other materials; in the building trades the most common use is to fasten or join together separate pieces (of timber etc).

(2) In anatomy, a thin, horny plate, consisting of modified epidermis, growing on the upper side of the end of a finger or toe; the toughened protective protein-keratin (known as alpha-keratin, also found in hair) at the end of an animal digit, such as fingernail.

(3) In zoology, the basal thickened portion of the anterior wings of certain hemiptera; the basal thickened portion of the anterior wings of certain hemiptera; the terminal horny plate on the beak of ducks, and other allied birds; the claw of a mammal, bird, or reptile.

(4) Historically, in England, a round pedestal on which merchants once carried out their business.

(5) A measure for a length for cloth, equal to 2¼ inches (57 mm) or 1⁄20 of an ell; 1⁄16 of a yard (archaic); it’s assumed the origin lies in the use to mark that length on the end of a yardstick.

(6) To fasten with a nail or nails; to hemmer in a nail.

(7) To enclose or confine (something) by nailing (often followed by up or down).

(8) To make fast or keep firmly in one place or position (also used figuratively).

(8) Perfectly to accomplish something (usually as “nailed it”).

(10) In law enforcement, to catch a suspect or find them in possession of contraband or engaged in some unlawful conduct (usually as “nailed them”).

(11) In Christianity, as “the nails”, the relics used in the crucifixion, nailing Christ to the cross at Golgotha.

(12) As a the nail (unit), an archaic multiplier equal to one sixteenth of a base unit

(13) In drug slang, a hypodermic needle, used for injecting drugs.

(14) To detect and expose (a lie, scandal, etc)

(15) In slang, to hit someone.

(16) In slang, intently to focus on someone or something.

Pre 900: From the Middle English noun nail & nayl, from the Old English nægl and cognate with the Old Frisian neil, the Old Saxon & Old High German nagal, the Dutch nagel, the German Nagel, the Old Norse nagl (fingernail), all of which were from the unattested Germanic naglaz.  As a derivative, it was akin to the Lithuanian nãgas & nagà (hoof), the Old Prussian nage (foot), the Old Church Slavonic noga (leg, foot), (the Serbo-Croatian nòga, the Czech noha, the Polish noga and the Russian nogá, all of which were probably originally a jocular reference to the foot as “a hoof”), the Old Church Slavonic nogŭtĭ, the Tocharian A maku & Tocharian B mekwa (fingernail, claw), all from the unattested North European Indo-European ənogwh-.  It was further akin to the Old Irish ingen, the Welsh ewin and the Breton ivin, from the unattested Celtic gwhīnā, the Latin unguis (fingernail, claw), from the unattested Italo-Celtic əngwhi-;the Greek ónyx (stem onych-), the Sanskrit ághri- (foot), from the unattested ághli-; the Armenian ełungn from the unattested onogwh-;the Middle English verbs naile, nail & nayle, the Old English næglian and cognate with the Old Saxon neglian, the Old High German negilen, the Old Norse negla, from the unattested Germanic nagl-janan (the Gothic was ganagljan).  The ultimate source was the primitive Indo-European h₃nog- (nail) and the use to describe the metal fastener was from the Middle English naylen, from the Old English næġlan & nægl (fingernail (handnægl)) & negel (tapering metal pin), from the Proto-Germanic naglaz (source also of Old Norse nagl (fingernail) & nagli (metal nail).  Nail is a noun & verb, nailernailless & naillike are adjectives, renail is a verbs, nailing is a noun & vern and nailed is a verb & adjective; the noun plural is nails.

Nail is modified or used as a modifier in literally dozens of examples including finger-nail, toe-nail, nail-brush, nail-file, rusty-nail, garden-nail, nail-fungus, nail-gun & frost-nail.  In idiomatic use, a “nail in one's coffin” is a experience or event that tends to shorten life or hasten the end of something (applied retrospectively (ie post-mortem) it’s usually in the form “final nail in the coffin”.  To be “hard as nails” is either to be “in a robust physical state” or “lacking in human feelings or without sentiment”. To “nail one's colors to the mast” is to declare one’s position on something.  Something described as “better than a poke in the eye with a rusty nail” is a thing, which while not ideal, is not wholly undesirable or without charm.  In financial matters (of payments), to be “on the nail” is to “pay at once”, often in the form “pay on the nail”.  To “nail something down” is to finalize it. To have “nailed it” is “to perfectly have accomplished something” while “nailed her” indicates “having enjoyed sexual intercourse with her”.  The “right” in the phrase “hit the nail right on the head” is a more recent addition, all known instances of use prior to 1700 being “hit the nail on the head” and the elegant original is much preferred.  It’s used to mean “correctly identify something or exactly to arrive at the correct answer”.  Interestingly, the Oxford English Dictionary (OED) notes there is no documentary evidence that the phrase comes from “nail” in the sense of the ting hit by a hammer.

Double-headed nails.

Double-headed nails are used for temporary structures like fencing.  When the shaft is hammered in to the point where the surface of the lower head is flat against the surface of that into which it's being hammered, it leaves the upper head standing proud with just enough of the shaft exposed to allow a claw-hammer to be used to extract nail.  There is a story that as part of an environmental protest against the building or demolition of some structure (the tales vary), activists early one morning went to the temporary fencing around the contested site and hammered in all the double-headed nails.  This is believed to be an urban myth.

The sense of “fingernail” appears to be the original which makes sense give there were fingernails before there were spikes (of metal or any other material) used to build stuff.  The verb nail was from the Old English næglian (to fix or fasten (something) onto (something else) with nails), from the Proto-Germanic ganaglijan (the source also of the Old Saxon neglian, the Old Norse negla, the Old High German negilen, the German nageln and the Gothic ganagljan (to nail), all developed from the root of the nouns.  The colloquial meaning “secure, succeed in catching or getting hold of (someone or something)” was in use by at least the 1760; hence (hence the law enforcement slang meaning “to effect an arrest”, noted since the 1930s.  The meaning “to succeed in hitting” dates from 1886 while the phrase “to nail down” (to fix in place with nails) was first recorded in the 1660s.

As a noun, “nail-biter” (worrisome or suspenseful event), perhaps surprisingly, seems not to have been in common use until 1999 an it’s applied to things from life-threatening situations to watching close sporting contests.  The idea of nail-biting as a sign of anxiety has been in various forms of literature since the 1570s, the noun nail-biting noted since 1805 and as a noun it was since the mid-nineteenth century applied to those individuals who “habitually or compulsively bit their fingernails” although this seems to have been purely literal rather than something figurative of a mental state.  Now, a “nail-biter” is one who is “habitually worried or apprehensive” and they’re often said to be “chewing the ends of their fingernails” and in political use, a “nail biter” is a criticism somewhat less cutting than “bed-wetter”.  The condition of compulsive nail-biting is the noun onychophagia, the construct being onycho- (a creation of the international scientific vocabulary), reflecting a New Latin combining form, from the Ancient Greek ὄνυξ (ónux) (claw, nail, hoof, talon) +‎ -phagia (eating, biting or swallowing), from the Ancient Greek -φαγία (-phagía).  A related form was -φαγος (-phagos) (eater), the suffix corresponding to φαγεῖν (phageîn) (to eat), the infinitive of ἔφαγον (éphagon) (I eat), which serves as aorist (essentially a compensator for sense-shifts) (for the defective verb ἐσθίω (esthíō) (I eat).  Bitter-tasting nail-polish is available for those who wish to cure themselves.  Nail-polish as a product dates from the 1880s and was originally literally a clear substance designed to give the finger or toe-nails a varnish like finish upon being buffed.  By 1884, it was being sold as “liquid nail varnish” including shads of black, pink and red although surviving depictions in art suggests men and women in various cultures have for thousands of years been coloring their nails.  Nail-files (small, flat, single-cut file for trimming the fingernails) seem first to have been sold in 1819 and nail-clippers (hand-tool used to trim the fingernails and toenails) in 1890.

The expression "nail down the lid" is a reference to the lid of a coffin (casket), the implication being one wants to make doubly certain anyone within can't possible "return from the dead".  The noun doornail (also door-nail) (large-headed nail used for studding batten doors for strength or ornament) emerged in the late fourteenth century and was often used of many large, thick nails with a large head, not necessarily those used only in doors.  The figurative expression “dead as a doornail” seems to be as old as the piece of hardware and use soon extended to “dumb as a doornail” and “deaf as a doornail).  The noun hangnail (also hang-nail) is a awful as it sounds and describes a “sore strip of partially detached flesh at the side of a nail of the finger or toe” and appears in seventeenth century texts although few etymologists appear to doubt it’s considerably older and probably a folk etymology and sense alteration of the Middle English agnail & angnail (corn on the foot), from the Old English agnail & angnail.  The origin is likely to have been literally the “painful spike” in the flesh when suffering the condition.  The first element was the Proto-Germanic ang- (compressed, hard, painful), from the primitive Indo-European root angh- (tight, painfully constricted, painful); the second the Old English nægl (spike), one of the influences on “nail”.  The noun hobnail was a “short, thick nail with a large head” which dates from the 1590s, the first element probably identical with hob (rounded peg or pin used as a mark or target in games (noted since the 1580s)) of unknown origin.  Because hobnails were hammered into the leather soles of heavy boots and shoes, “hobnail” came in the seventeenth century to be used of “a rustic person” though it was though less offensive than forms like “yokel”.

Nails and pins

Mug shot “pin” from TeePublic featuring Lindsay Lohan (b 1986, left), Donald Trump (b 1946; POTUS 2017-2021 and since 2025) and Paris Hilton (b 1981, right).  In this context, although the product really is “the badge”, the name was gained from the built-in pin supplied to secure the object to clothing.

As designs, a nail and a pin are similar, obviously differing only in scale but the function of each is different.  A nail’s primary purpose is to function as a structural fastener joining materials (most typically two or more pieces of wood) although there are specialized nails driven into substrate by impact (variously with hammers or nail guns (sometimes called “pin-nailers”, some of which are built to fire “panel pins” (very slender nails) or small “headless nails”).  A nail relies on friction and compression in the surrounding material for its holding strength.  Pins look like scaled-down nails but mostly are used for alignment, retention or pivoting, rather than structural load-bearing.  Because of their more delicate construction, pins often are inserted through specific-purpose, pre-existing holes and in many cases are intended to be temporary and are thus removable.  Visually, both nails and pins have heads (round, flat, clipped etc) and a tapered shank with a tip pointed for pointed tip for penetration (“snub-nosed” nails do exist but are rare) and both are designed slightly to deform the surrounding material when driven.  The most obvious difference is that a pin’s head is very small and some are spherical and made from plastic; they’re designed only to be pushed with finger-pressure rather than being hit with a hammer.  Although the term “pin” is used for some specialized devices used in building and engineering (dowel pin, pivot pin, gudgeon pin (also as wrist pin), roll pin, cotter pin etc), the word is most associated with the tailor’s pin (used mostly in textiles and usually clipped to “pin”).  In jewelry design and textiles there are also variants including the “lapel pin” and the fashion industry’s device of last resort, the “safety pin”.

Pinhead in publicity shot for Hellraiser III: Hell on Earth (1992).

Clive Barker's (b 1952) supernatural horror movie Hellraiser (1987) was based on his novella The Hellbound Heart (1986) and was a surprise hit, making it a franchise which has thus far spawned nine sequels, the most recent released in 2022.  The plot involved a mysterious puzzle box that, when opened, summoned the Cenobites, a group of extra-dimensional, sadomasochistic beings unable to differentiate between pain and pleasure.  It was a good premise for a horror movie but the character who really captured the audience's imagination was the unnamed figure viewers dubbed “Pinhead”.  Although Pinhead appeared in the original film for fewer than ten minutes, the character became the franchise’s focal point and has since dominated the publicity material for subsequent releases.  The popularity of Hellraiser has been maintained and it’s hoped that for the next release the producers will offer the part to Peter Dutton (b 1970; leader of the Liberal Party of Australia 2022-2025).

Peter Dutton captured by a photographer during a happy moment (left), Pinhead with the box able to summon the Cenobites (centre) and and artist's depiction of Mr Dutton in “Pinhead mode” (digitally altered image, right).

No longer burdened with tiresome parliamentary duties since losing his seat in the 2025 Australian general election, Mr Dutton has time for a third career and he should be good at playing an unsmiling character who speaks in a relentless monotone; really, all he need do is act naturally.  It’s suspected also he’ll be good at learning a script given the decades he spent parroting “talking points” and TWS (three word slogans).  While it’s an urban myth Mr Dutton wasn’t offered the part of Lord Voldemort in the Harry Potter movie franchise because he was deemed “too scary”, as Pinhead he’d be “just scary enough”.  While the LNP (Liberal National Party) state government in Queensland recently has appointed Mr Dutton to the board of the QIC (Queensland Investment Corporation, the investment manager of the state’s Aus$135 billion in assets), it’s understood his duties in the Aus$130,000 per annum role will be neither onerous or time-consuming so there’ll be ample opportunity for film-shoots.  Although when in opposition the LNP had decried the ALP (Australian Labor Party) government’s frequent appointment of ALP figures to lucrative sinecures, once in office the LNP continued the “jobs for the boys” tradition.  In the modern era, the two most striking characteristics of right-wing fanatics is (1) a fondness for sitting safely in a bunker while advocating for (and sometimes sending) other people's children to go a fight a war somewhere and (2) after a career spent extolling the virtues of “private enterprise” and criticizing “government waste”, being anxious to get back on the public payroll as soon as their political careers end.  Reassuringly for taxpayers who may have been worried Mr Dutton would not be able to continue to enjoy the lifestyle to which their taxes made him accustomed (“entitled” as he might have put it), it’s believed his director’s fees from QIC will not affect his parliamentary pension (understood to be between Aus$260,000-Aus$280,000 per annum).

The Buick Nailhead

In the 1930s, the straight-8 became a favorite for manufacturers of luxury cars, attracted by its ease of manufacture (components and assembly-line tooling able to be shared with those used to produce a straight-6), the mechanical smoothness inherent in the layout and the ease of maintenance afforded by the long, narrow configuration, ancillary components readily accessible.  However, the limitations were the relatively slow engine speeds imposed by the need to restrict the “crankshaft flex” and the height of the units, a product of the long strokes used to gain the required displacement.  By the 1950s, it was clear the future lay in big-bore, overhead valve V8s although the Mercedes-Benz engineers, unable to forget the glory days of the 1930s when the straight-eight W125s built for the Grand Prix circuits generated power and speed Formula One wouldn’t see until the 1980s, noted the relatively small 2.5 litre (153 cubic inch) displacement limit for 1954 and conjured up a final fling for the layout.  Used in both Formula One as the W196R and in sports car racing as the W196S (better remembered as the 300 SLR) the new 2.5 & 3.0 litre (183 cubic inch) straight-8s, unlike their pre-war predecessors, solved the issue of crankshaft flex (the W196's redline was 9500 compared with the W125's 5800) by locating the power take-off at the centre, adding mechanical fuel-injection and a desmodromic valve train to make the things an exotic cocktail of ancient & modern (on smooth racetracks and in the hands of skilled drivers, the swing axles at the back not the liability they might sound).  Dominant during 1954-1955 in both Formula One & the World Sports Car Championship, they were the last of the straight-8s in top-line competition.

Schematic of Buick “Nailhead” V8, 1953-1966.

Across the Atlantic, the US manufacturers also abandoned their straight-8s.  Buick introduced their overhead valve (OHV) V8 in 1953 but, being much wider than before, the new engine had to be slimmed somewhere to fit between the existing inner-fenders (it would not be until later the platform was widened).  To achieve this, the engineers narrowed the cylinder heads, compelling both a conical (the so-called “pent-roof”) combustion chamber and an arrangement in which the sixteen valves pointed directly upwards on the intake side, something which not only demanded an unusual pushrod & rocker mechanism but also limited the size of the valves.  So, the valves had to be tall and narrow and, with some resemblance to nails, they picked up the nickname “nail valves”, morphing eventually to “nailhead” as a description of the whole engine.  The valve placement and angle certainly benefited the intake side but the geometry compromised the flow of exhaust gases which were compelled by their anyway small ports to make a turn of almost 180^o on their way to the tailpipe.  As an indication of the heat-soak generated by that 180^o turn, the surrounding water passages were very wide. 

It wasn't the last time the head design of a Detroit V8 would be dictated by considerations of width.  When Chrysler in 1964 introduced the 273 cubic inch (4.5 litre) V8 as the first of its LA-Series (that would begat the later 318 (5.2), 340 (5.5) & 360 (5.9) as well as the V10 made famous in the Dodge Viper), the most obvious visual difference from the earlier A-Series V8s was the noticeably smaller cylinder heads.  The A engines used as skew-type valve arrangement in which the exhaust valve was parallel to the bore with the intake valve tipped toward the intake manifold (the classic polyspherical chamber).  For the LA, Chrysler rendered all the valves tipped to the intake manifold and in-line (as viewed from the front), the industry’s standard approach to a wedge combustion chamber.  The reason for the change was that the decision had been taken to offer the compact Valiant with a V8 but it was a car which had been designed to accommodate only a straight-six and the wide-shouldered polyspheric head A-Series V8s simply wouldn’t fit.  So, essentially, wedge-heads were bolted atop the old A-Series block but the “L” in LA stood for light and the engineers wanted something genuinely lighter for the compact (in contemporary US terms) Valiant.  Accordingly, in addition to the reduced size of the heads and intake manifold, a new casting process was developed for the block (the biggest, heaviest part of an engine) which made possible thinner walls.  "Light" is however a relative term and the LA series was notably larger and heavier than Ford's "Windsor" V8 (1961-2000) which was the exemplar of the "thin-wall" technique.  This was confirmed in 1967 when, after taking control of Rootes Group, Chrysler had intended to continue production of the Sunbeam Tiger, by then powered by the Ford Windsor 289 (4.7 litre) but with Chrysler’s 273 LA V8 substituted.  Unfortunately, while 4.7 Ford litres filled it to the brim, 4.4 Chrysler litres overflowed; the Windsor truly was compact.  Allowing it to remain in production until the stock of already purchased Ford engines had been exhausted, Chrysler instead changed the advertising from emphasizing the “…mighty Ford V8 power plant” to the vaguely ambiguous “…an American V-8 power train”.

The nailhead wasn’t ideal for producing top-end power but the design did generate prodigious low-end torque, something much appreciated by Buick's previous generation of buyers who much had relished the low-speed responsiveness of the famously smooth straight-8.  However, like everybody else, Buick hadn’t anticipated that as the 1950s unfolded, the industry would engage in a “power race”, something to which the free-breathing Cadillac V8s and Chrysler’s Hemis were well-suited.  For that, the somewhat strangulated Buick Nailhead was not at all suited and to gain power the engineers were compelled to add high-lift, long-duration camshafts which enabled the then magic 300 HP (horsepower) number to be achieved but at the expense of smoothness; tales of Buick buyers (long accustomed to straight-8s that ran so smoothly at idle it could be hard to tell if the things were running) returning to the dealer to fix the “rumpity-rump” became legion.  Still, the Nailhead was robust, relatively light and offered what was then a generous displacement and the ever inventive hot-rod community soon worked out the path to power was to use forced induction and invert the valve use, the supercharger blowing the fuel-air mix into the combustion chambers through the exhaust ports while the exhaust gases were evacuated through the larger intake ports.  Thus, for a while, the Nailhead enjoyed a role as a niche player although the arrival in the mid 1950s of the much more tuneable Chevrolet V8s ended the vogue for all but a few devotees who continued use well into the 1960s.  Buick acknowledged reality and, unusually, instead of following the industry trend and drawing attention to displacement & power, publicized their big torque numbers, confusing some (though probably not Buick buyers who were a loyal crew who sometimes would look down on more expensive Cadillacs because they were "flashy").  The unique appearance of the old Nailhead retains some nostalgic appeal for the modern hot-rod community and they do sometimes appear, a welcome change from the more typical small-block Fords or Chevrolets.

Lockheed SR-71 Blackbird (1964-1999).

Not confused about numbers was the USAF (United States Air Force) which was much interested in power for its aircraft but also had a special need for torque on the tarmac and briefly that meant another quirky niche for the Nailhead.  The Lockheed SR-71 Blackbird (1964-1979) was a long-range, high-altitude supersonic (Mach 3+) aircraft used by the USAF for reconnaissance between 1966-1998 and by the NASA (National Aeronautics & Space Administration) for observation missions as late as 1999.  Something of a high-water mark among the extraordinary advances made in aeronautics and materials construction during the Cold War, the SR-71 used Pratt & Whitney J58 turbojet engines which featured an innovative, secondary air-injection system for the afterburner, permitting additional thrust at high speed.  The SR-71 still holds a number of altitude and speed records and Lockheed’s SR-72, a hypersonic unmanned aerial vehicle (UAV) is said to be in an “advanced stage” of design and construction although whether any test flights will be conducted before 2030 remains unclear, the challenges of sustaining in the atmosphere velocities as high as Mach 6+ onerous given the heat generated and stresses imposed by the the fluid dynamics of air at high speed.

At the time, the SR-71 was the most exotic aircraft on the planet but during testing and early in its career, just for the engines to start it relied on a pair of even then technologically bankrupt Buick Nailhead V8s.  These were mounted in a towed cart and were effectively the turbojet’s starter motor, a concept developed in the 1930s as a work-around for the technology gap which emerged as the V12 aero-engines became too big to start by hand but lacked on-board electrical systems to trigger ignition.  The two Nailheads were connected by gears to a single, vertical drive shaft which ran the jet up to the critical speed at which ignition became self-sustaining.  The engineers chose the Nailheads after comparing them to other large displacement V8s, the aspect of the Buicks which most appealed being the torque generated at relatively low engine speeds, a characteristic ideal for driving an output shaft, torque best visualized as a "twisting" force.  After the Nailhead was retired in 1966, later carts used Chevrolet big-block V8s but in 1969 a pneumatic start system was added to the infrastructure of the USAF bases from which the SR-71s most frequently operated, the sixteen-cylinder carts relegated to secondary fields the planes rarely used.

Carnival

Carnival (pronounced kahr-nuh-vuhl)

(1) A traveling amusement show, having sideshows, rides etc.

(2) Any merrymaking, revelry, or festival, as a program of sports or entertainment.

(3) In the Christian ecclesiastical calendar, the season immediately preceding Lent, often observed with merrymaking; Shrovetide.

(4) A festive occasion or period marked by merrymaking, processions etc and historically much associated with Roman Catholic countries in the period just before Lent.

(5) A sports meeting.

(6) In literary theory (as the noun carnivalization & verb carnivalize), to subvert (orthodox assumptions or literary styles) through humour and chaos.

(7) In sociology, a context in which transgression or inversion of the social order is given temporary license (an extension of the use in literary theory).

(8) Figuratively, a gaudily chaotic situation.

(9) As a modifier (often as “carnival atmosphere?”) a festive atmosphere.

1540–1550: From the Middle French carnaval, from the Italian carnevale, from the Old Italian carnelevare (taking meat away), from older Italian forms such as the Milanese carnelevale or Old Pisan carnelevare (to remove meat (literally “raising flesh”)) the construct built from the Latin caro (flesh (originally “a piece of flesh”)) from the primitive Indo-European root sker- (to cut) + levare (lighten, raise, remove), from the primitive Indo-European root legwh- (not heavy, having little weight).  Etymologists are divided on the original source of the term used by the Church, the alternatives being (1) carnem levare (to put away flesh), (2) carnem levāmen (meat dismissal), (3) carnuālia (meat-based country feast) and (4) carrus nāvālis (boat wagon; float).  What all agree upon is the ecclesiastical use would have come from one of the forms related to “meat” and the folk etymology favors the Medieval Latin carne vale (flesh, farewell!).  Spreading from the use in Christian feast days, by at least the 1590s it was used in the sense of “feasting or revelry in general” while the meaning “a circus or amusement fair” appears to be a 1920s adoption in US English.  The synonyms can include festival, celebration, festivity, fiesta, jubilee, gala, fete, fête, fest, fair, funfair, exhibit, exhibition, revelry, merriment, rejoicing, jamboree, merrymaking, mardi gras, jollity, revel, jollification, exposition and show.  Which is chosen will be dependent on region, context, history etc and (other than in ecclesiastical use) rules mostly don’t exist but there seem to be a convention that a “sporting carnival” is a less formal event (ie non-championship or lower level competitions).  The alternative spelling carnaval is obsolete.  Carnival & carnivalization are nouns, carnivalize, carnivalizing & carnivalized are verbs, and carnivalic, carnivalistic, carnivalesque, carnivallike, precarnival & noncarnival are adjectives; the noun plural is carnivals.

Not just meat: Francis (1936-2025; pope 2013-2025) on fasting for Lent.

Originally, a carnival was a feast observed by Christians before the Lenten fast began and wasn’t a prelude to a sort of proto-veganism.  It was a part of one of religion’s many dietary rules, one which required Christians to abstain from meat during Lent (particularly on Fridays and during certain fast days), carnival the last occasion on which meat was permissible before Easter.  The Christian practice of abstaining from meat evolved as part of a broader theology of penance, self-denial, and imitation of Christ’s suffering, the rationale combining biblical precedent, symbolic associations and early ascetic traditions, the core of the concept Christ’s 40 days of fasting in the wilderness (Matthew 4:1–11, Luke 4:1–13).  Theologically, the argument was that for one’s eternal soul to enter the Kingdom of Heaven, a price to be paid was Imitatio Christi (earthly participation in Christ’s suffering).  Much the early church valued suffering (for the congregants if not the clergy and nobility) and the notion remains an essential theme in some Christian traditions which can be summed up in the helpful advice: “For everything you do, there’s a price to be paid.”

Donald Trump (b 1946; US president 2017-2021 and since 2025) in 2016 on his private jet, fasting for Lent.

By voluntarily abstaining from certain foods, Christians imitated Christ’s self-denial and prepared spiritually for Easter: sharing in His suffering to grow in holiness.  Meat was seen a symbol of feasting and indulgence, an inheritance from Antiquity when “flesh of the beasts of the field” was associated with celebration rather than everyday subsistence, the latter something sustained typically by seafood, fruits and grains so voluntarily (albeit at the behest of the Church) choosing temporarily to renounce meat symbolized forgoing luxury and bodily pleasure, cultivating humility and penitence.  As well as the theological, there was also a quasi-medical aspect to what Tertullian (Quintus Septimius Florens Tertullianus, circa 155–circa 220) commended as “forsaking worldly indulgence” in that fasting took one’s thoughts away from earthly delights, allowing a focus on “prayer and spiritual discipline”, strengthening the soul against “sinful temptations”.  Another layer was added by the Patristics (from the Latin pater (father)), a school of thought which explored the writings and teachings of the early Church Fathers.  Although it was never a universal view in Patrology, there were those who saw in the eating of meat a connection to animal sacrifice and blood, forbidden in the Old Testament’s dietary laws and later spiritualized in Christianity, thus the idea of abstinence as a distancing from violence and sensuality.  Finally, there was the special significance of Fridays, which, as "Good Friday" reflected the remembrance of the crucifixion of Christ and his death at Calvary (Golgotha); the early Christians treated every Friday as a mini-fast and later this would be institutionalized as Lent.

The allowance of fish during Lent had both pragmatic and theological origins, its place in the Christian diet a brew of symbolism, biblical precedent and cultural context.  As a legal and linguistic point, in the Greco-Roman scheme of things fish was not thought “flesh meat” which was understood as coming from warm-blooded land animals and birds.  Fish, cold-blooded and aquatic, obviously were different and belonged to a separate category, one which Christianity inherited and an implication of the distinction was seafood being viewed as “everyday food” rather than an indulgent luxury.  This was a thing also of economics (and thus social class), the eating of fish much associated with the poorer coastal dwellers whereas meat was more often seen on urban tables.  Notably, there was also in this a technological imperative: in the pre-refrigeration age, in hot climates, often it wasn’t possible safely to transport seafood inland.  The Biblical symbolism included Christ feeding the multitudes with a few “loaves and fishes” (Matthew 14:13–21), several of the apostles were fishermen who Christ called upon to be “fishers of men” (Mark 1:16–18) and the ichthys (fish symbol) was adopted as early Christian emblem for Christ Himself.  Collectively, this made fish an acceptably modest food for a penitential season.  All that might have been thought justification enough but, typically, Medieval scholars couldn’t resist a bit of gloss and the Italian Dominican friar, philosopher & theologian Saint Thomas Aquinas (1225–1274) decided abstinence aimed to “curb the concupiscence of the flesh” and, because meat generated more “bodily heat” and pleasure than fish, it was forbidden while fish was not.  That wasn’t wholly speculative and reflected the humoral theory from Antiquity, still an orthodoxy during the Middle Ages: fish seen as lighter, cooler, and less sensual.

Traditionally, there was also a Lenten prohibition of dairy products and eggs, each proscription with its own historical and symbolic logic and the basis of Shrove Tuesday (Pancake Day) and Easter eggs (though not the definitely un-Christian Easter bunny).  The strictness derived partly from Jewish precedents notably the vegetarian edict in Daniel 10:2–3 and the idea of a “return to Edenic simplicity” where man would eat only plants (Genesis 1:29) but also an aversion to links with sexuality and fertility, eggs obviously connected with sexual reproduction and dairy with lactation.  What this meant was early Christian asceticism sought to curb bodily impulses and anything connected with fleshly generation and (even if indirectly), thoughts of sex.

Historically, a time of absolution when confessions were made in preparation for Lent, Shrovetide described the three days immediately preceding Lent (Shrove Sunday, Shrove Monday & Shrove Tuesday, preceding Ash Wednesday).  The construct being shrove +‎ -tide, the word was from the late Middle English shroftyde.  Shrove was the simple past of shrive, from the Middle English shryven, shriven & schrifen, from the Old English sċrīfan (to decree, pass judgement, prescribe; (of a priest) to prescribe penance or absolution), from the Proto-West Germanic skrīban, from the late Proto-Germanic skrībaną, a borrowing from the Latin scrībō (write).  The word may be compared with the West Frisian skriuwe (to write), the Low German schrieven (to write), the Dutch schrijven (to write), the German schreiben (to write), the Danish skrive (to write), the Swedish skriva (to write) and the Icelandic skrifa (to write).  The –tide suffix was from the Middle English –tide & -tyde, from the Old English -tīd (in compounds), from tīd (point or portion of time, due time, period, season; feast-day, canonical hour).  Before refrigeration, eggs and dairy naturally accumulated during springtime as hens resumed laying and animals produced more milk.  Being banned during Lent, stocks thus had to be consumed lest they be wasted so a pragmatic way to ensure economy of use was the pancake (made with butter, milk & eggs), served on the feast of Shrove Tuesday (Pancake Day).  Following Easter, when eggs returned to the acceptable list, “Easter eggs” were a natural festive marker of the fast’s end.

Although dubbed “floating Petri dishes” because of the high number of food poisoning & norovirus cases, cruise ships remain popular, largely because, on the basis of cost-breakdown, they offer value-for-money packages few land-based operators can match.  The infections are so numerous because (1) there are thousands of passengers & crew in a closed, crowded environment, (2) an extensive use of buffets and high-volume food service, (3) a frequent turnover of crew & passengers, (4) port visits to places with inconsistent sanitation, health & food safety standards and (5) sometimes delayed reporting and patient isolation.

However, although the popular conception of Medieval Western Christendom is of a dictatorial, priest-ridden culture, the Church was a political structure and it needed to be cognizant of practicalities and public opinion.  Even dictatorships can maintain their authority only with public consent (or at least acquiescence) and in many places the Church recognized burdensome rules could be counter-productive, onerous dietary restrictions resented especially by the majority engaged for their living in hard, manual labor.  Dispensations (formal exceptions) became common with bishops routinely relaxing the rules for the ill, those pregnant or nursing or workers performing physically demanding tasks.  As is a common pattern when rules selectively are eased, a more permissive environment was by the late Middle Ages fairly generalized (other than for those who chose to live by to monastic standards).

The growth of dispensations (especially in the form of “indulgences” which were a trigger for the Protestant Reformation) was such it occurred to the bishops they’d created a commodity and commodities can be sold.  This happened throughout Europe but, in France and Germany, the “system” became institutionalized, the faithful even able to pay “butter money” for the privilege of eating the stuff over Lent (a kind of inverted “fat tax”!) with the proceeds devoted to that favourite capital works programme of bishops & cardinals: big buildings.  The sixteenth century tower on Normandy’s Rouen Cathedral was nicknamed “Butter Tower” although the funds collected from the “tax” covered only part of the cost; apparently even the French didn’t eat enough butter.  As things turned out, rising prosperity and the population drifts towards towns and cities meant consumption of meat and other animal products increased, making restrictions harder to enforce and the Protestant reformers anyway rejected mandatory fasting rules, damning them as man-made (“Popery!” the most offensive way they could think to express that idea) rather than divine law.  Seeing the writing nailed to the door, one of the results of the Council of Trent (1545–1563) was that while the Church reaffirmed fasting, eggs and dairy mostly were allowed and the ban on meat was restricted to Fridays and certain fast days in the ecclesiastical calendar.

By the twentieth century, it was clear the Holy See was fighting a losing battle and in February 1966, Paul VI (1897-1978; pope 1963-1978) promulgated the Apostolic Constitution Paenitemini (best translated as “to be penitent”) making abstinence from meat on Fridays optional outside Lent and retained only Ash Wednesday and Good Friday as obligatory fast days for Catholics.  It was a retreat very much in the corrosive spirit of the Second Vatican Council (Vatican II, 1962-1965) and an indication the Church was descending to a kind of “mix & match” operation, people able to choose the bits they liked, discarding or ignoring anything tiresome or too onerous.  In truth, plenty of priests had been known on Fridays to sprinkle a few drops of holy water on their steak and declare “In the name of our Lord, you are now fish”.  That was fine for priests but for the faithful, dispensation was often the “luck of clerical draw”.  At a time in the late 1940s when there was a shortage of good quality fish in south-east Australia, Sir Norman Gilroy (1896–1977; Roman Catholic Archbishop of Sydney 1940-1971, appointed cardinal 1946) granted dispensation but the stern Dr Daniel Mannix (1864–1963; Roman Catholic Archbishop of Melbourne 1917-1963) refused so when two politicians from New South Wales (Ben Chifley (1885–1951; prime minister of Australia 1945-1949) and Fred Daly (1912–1995)) one Friday arrived in the parliamentary dining room for dinner, Chifley’s order was: “steaks for me and Daly, fish for the Mannix men.”

In the broad, a carnival was an occasion, event or season of revels, merrymaking, feasting and entertainments (the Spanish fiestas a classic example) although they could assume a political dimension, some carnivals staged to be symbolic of the disruption and subversion of authority.  The idea was a “turning upside down of the established hierarchical order” and names used included “the Feast of Fools”, “the Abbot of Misrule” and “the Boy Bishop”.  With a nod to this tradition, in literary theory, the concept of “carnivalization” was introduced by the Russian philosopher & literary critic Mikhail Bakhtin (1895–1975), the word appearing first in the chapter From the Prehistory of Novelistic Discourse (written in 1940) which appeared in his book The Dialogic Imagination: chronotope and heteroglossia (1975).  What carnivalization described was the penetration or incorporation of carnival into everyday life and its “shaping” effect on language and literature.

The Socratic dialogues (most associated with the writing of the Greek philosophers Xenophon (circa 430–355 BC) and Plato (circa 427-348 BC)) are regarded as early examples of a kind of carnivalization in that what appeared to be orthodox “logic” was “stood on its head” and shown to be illogical although Menippean satire (named after the third-century-BC Greek Cynic Menippus) is in the extent of its irreverence closer to the modern understanding which finds expression in personal satire, burlesque and parody.  Bakhtin’s theory suggested the element of carnival in literature is subversive in that it seeks to disrupts authority and introduce alternatives: a deliberate affront to the canonical thoughts of Renaissance culture.  In modern literary use the usual term is “carnivalesque”, referring to that which seeks to subvert (“liberate” sometimes the preferred word) assumptions or orthodoxies by the use of humor or some chaotic element.  This can be on a grand scale (ie an entire cultural movement) or as localized some malcontent disrupting their book club (usually polite affairs where novels are read and ladies sit around talking about their feelings).

He expanded on the theme in his book Problems of Dostoevsky's Poetics (1929) by contrasting the novels of Leo Tolstoy (1828-1910) and Fyodor Dostoevsky (1821–1881).  Tolstoy’s fiction he classified as a type of “monologic” in which all is subject to the author's controlling purpose and hand, whereas for Dostoevsky the text is “dialogic” or “polyphonic” with an array of different characters expressing a variety of independent views (not “controlled” the author) in order to represent the author's viewpoint.  Thus deconstructed, Bakhtin defined these views as “not only objects of the author's word, but subjects of their own directly significant word as well” and thus vested with their own dynamic, being a liberating influence which, as it were, “conceptualizes” reality, lending freedom to the individual character and subverting the type of “monologic” discourse characteristic of many nineteenth century authors (typified by Tolstoy).

Dostoevsky’s story Bobok (1873) is cited as an exemplar of carnival.  It has characters with unusual freedom to speak because, being dead, they’re wholly disencumbered of natural laws, able to say what they wish and speak truth for fun.  However, Bakhtin did acknowledge this still is literature and didn’t claim a text could be an abstraction uncontrolled by the author (although such things certainly could be emulated): Dostoevsky (his hero) remained in control of his material because the author is the directing agent.  So, given subversion, literary and otherwise, clearly has a history dating back doubtlessly as many millennia as required to find an orthodoxy to subvert, why was the concept of carnivalization deemed a necessary addition to literary theory?  It went to the form of things, carnivalization able especially to subvert because it tended to be presented in ways less obviously threatening than might be typical of polemics or actual violence.
