From the Middle English bolt (verb) and the Old English (noun); it was cognate with the Dutch bout and the German Boltz.  The Old English bolt (short, stout arrow with a heavy head; crossbow for throwing bolts) was from the Proto-Germanic bultas, source also of the Old Norse bolti, the Danish bolt, the Dutch bout & the German Bolzen.  The original meaning may have been or connected in some sense with "arrow, missile" and therefore derived from the primitive Indo-European bheld- (to knock, strike), source also of the Lithuanian beldžiu (I knock) & baldas (pole for striking).  The word has since Middle English been applied to short metal rods (especially those with knobbed ends) meaning variously "stout pin for fastening objects together" and "part of a lock which springs out" both from circa 1400. A bolt of canvas or (circa 1400 and later applied to other fabrics) was so called for its shape.  The adverbial phrase bolt upright (like a bolt or arrow) is from the late fourteenth century.  The sense of a "sliding metal rod that thrusts the cartridge into the chamber of a firearm" is from 1859.  From the notion of an arrow's flight comes the bolt of lightning (1530s) and the sense of "a sudden spring or start" is attested from the 1540s.

The –er suffix was from the Middle English –er & -ere, from the Old English -ere, from the Proto-Germanic -ārijaz, thought usually to have been borrowed from Latin –ārius and reinforced by the synonymous but unrelated Old French –or & -eor (the Anglo-Norman variant was -our), from the Latin -ātor & -tor, from the primitive Indo-European -tōr.  As an abbreviation (or sometimes following a number), it’s written sometimes as -'er.  The suffix was added to verbs, forming an agent noun to describe a person or thing that does an action indicated by the root verb.  The antonym suffix was –ee which was added to nouns to denote an occupation, hobby etc and to numbers to denote a quantified set.  The related forms were the present participle bolting and the simple past and past participle bolted.  In one sense, the use by Shakespeare in Macbeth (1623) made specific what was once more general.  In Middle English, it meant “to smear or be smeared with a grimy substance” and was applied usually to farm animals getting wet with sweat, rain etc and then "boltering" with mud, hair etc.  However, the Shakespearian purloin popularized the term as means to describe getting covered in blood and that became the most common use in that context.  Bolter is a noun; the noun plural is bolters.

Bolter entered popular culture after the publication in 1945 of Nancy Mitford’s (1904-1973) The Pursuit of Love (1945) in which one character, (the bolter) was so named because of her many marriages, a consequence of her tendency to bolt from one relationship to another; throughout the novel, the bolter is never named and is referred to by all as “the bolter”.  Love in a Cold Climate (1949) was a companion volume to The Pursuit of Love, the title a direct quotation from George Orwell's (1903-1950) Keep the Aspidistra Flying (1936).  The usual form of expression is: “she’s a bit of a bolter”, borrowed from the use to refer to a flighty horse and historically, was applied only to wives and girlfriends; for unreliable men, women have many other epithets.  Mitford based the character on Lady Myra Idina Sackville (1893-1955), daughter of the eighth Earl De La Warr (1869-1915) and Lady Muriel Agnes Brassey (1872-1930).  Known always by her middle name, Idina, she led what many considered a scandalous life and married and divorced five times, her other connection with unconventionality that she was the cousin of the writer Vita Sackville-West (1892-1962), remembered for many things including her long marriage to the writer Harold Nicholson (1886-1968) and being the inspiration for the protagonist of Orlando: A Biography, by Virginia Woolf (1882-1941), one of her lovers.

1350–1400: From the Middle English act & acte, from the Old French acte, from the Latin ācta (register of events), plural of āctum (decree, law (later “something done”)), noun use of the past participle of agere (to set in motion, drive, drive forward", hence "to do, perform" and figuratively "incite to action; keep in movement, stir up" a verb with a broad range of meaning in Latin, including "act on stage, play the part of; plead a cause at law; chase; carry off, steal”), the construct being āg- (past participle stem) + -tum (the neuter past participle suffix) and directly from the Latin āctus (a doing; a driving, impulse, a setting in motion; a part in a play), the construct being āg- + -tus (the suffix of verbal action); the ultimate source was the primitive Indo-European héǵeti. The word partially displaced deed (which endured also to enjoy a specific meaning in law), from the Old English dǣd (act, deed).  Source of it all was the primitive Indo-European root ag- (to drive, draw out or forth, move).  The present participle is acting, the past participle acted.

The theatrical (part of a play (from the 1510s)) and the early fifteenth century legislative senses of the word existed also in Latin although the idea of "one of a series of performances in a variety show" seems not to have been in use until the 1890s although such forms of entertainment were by then long-established.  The (usually disparaging) use to suggest a "display of exaggerated behavior" is from 1928, extended from the theatrical sense.  The "act of God” (a natural force or event uncontrollable by man) was first recorded in 1726 as a legal term to refer to matters in which plaintiffs could not sue for compensation or relief because the consequent losses could not by anyone have been “…guarded against by the ordinary exertions of human skill and prudence so as to prevent its effect.”  Even Adolf Hitler (who wasn't fond of of churches and priests (the Roman Catholic ones he called "black crows") found it often convenient to invoke the name of the Almighty) found the concept helpful, describing the destruction of the Hindenburg dirigible in 1937 as “an act of God”.  The word had been in the language of law for a while, an act in the 1590s understood as something "in the process" and legal scholars link this with the late sixteenth century use of act as a euphemism for "sexual intercourse”.

The verb was a mid fifteenth century development from the noun and most of the modern senses in English probably are from the noun.  In the mid 1400s, it began with the sense of "to act upon or adjudicate in legal matters” before from circa 1600 coming to be used in the familiar general meaning of "to do, perform, transact", extended to things in the sense of "do something, exert energy or force”, by 1751, a use which would become increasingly common in physics and cosmology.  In theatrical performances, from the 1590s it meant to "perform as an actor" (intransitive) and by the 1610s "represent by performance on the stage" (transitive). The meaning "perform specific duties or functions," often on a temporary basis, had come into use by 1804 and was given a new legitimacy when the Duke of Wellington (1769–1852; UK prime-minister 1828-1830) was described as “acting prime-minister” between November-December 1834 while awaiting the return from Italy of the king’s appointee.  One verb form which in general use didn’t survive was co-act ("to act together in a performance), noted from circa 1600 and which begat co-action; co-active; co-actor etc although co-act (and variations) is still sometimes used in scientific papers.

To “act on” in the sense of "to exert influence upon" entered general use in the 1810s, the adoption encouraged by the increasing appearance of the phrase in scientific literature.  To “act up” came by 1900 mean "be unruly" (in reference to a horse in the same way bolter (ie “to bolt” in the sense of “gallop off without warning”)) was used, a reversal of the earlier meaning "acting in accordance with a duty, expectation, or belief” which dates from 1645.  To “act out” (behave anti-socially) was part of the jargon of psychiatry noted first in 1974; it meant "expressing one's unconscious impulses or desires", following “acting out” (abnormal behavior caused by unconscious influences) from 1945.

The idiomatic forms are legion.  “To get into the act” (participate) dates from 1947 and “to get (one's) act together” (organize one's chaotic life) is said not to have been used until the mid-1970s which seems surprising but more than one source records this.  The idea of the “one-act” was borrowed from the literal “one act play” (a performance consisting of a single act), noted since 1888, the figurative use suggesting either brevity or inadequacy depending on context.  The verb overact (to go too far in action) faded from use except in its original sense from the theatre where it described an actor “playing a part with too much emphasis; an extravagant and unnatural manner”.  The theatrical slang encapsulating this was “chewing the scenery", which sounds modern but dates from the 1630s.  To “act one’s age” is to behave in a manner befitting the maturity one is presumed to have attained at a certain stage in life.  An “act of faith” is to embark on a course of action on either (1) a basis of trust rather than any guarantee or (2) as a demonstration one's religious faith.

Acts & Scenes

William Shakespeare agitprop.

The act is a major division in many performance pieces such as plays, film, opera etc and frequently (though not of necessity) consists of a number of scenes, the concept dating from the theatre of antiquity.  Traditionally, the division of a work into acts and scenes was undertaken by the author but such delineations, especially of older material, can be made by critics or those applying academic analysis and where the notion of authorship can become blurred (such as a film director interpreting a text), there can be variations from the original, something sometimes controversial.  The application of the concept (and the labels) of acts and scenes is widely applied to many forms of entertainment, sometimes to provide a structural framework and sometimes, one suspects, to lend a not always deserved gravitas.  In the production of more recent material, commercial imperatives can also dictate the divisions, the single intermission a common occurrence which renders a performance inherently a two-stage event in some sense.

The three-act structure.

The number of acts in a piece need not bear any relationship to its length although this certainly is the general tendency, a one act play usually a deliberately short work.  Although the five act structure had until the early nineteenth century been most frequently used by playwrights, many analysts suggest this was a kind of formalism, a deferential (and perhaps devotional) nod to William Shakespeare (circa 1564–1616) who usually adhered to the five act model in his plays.  The bard had his reasons and there is a discernible rhythm as his five acts evolve but none the less, even in the most intricate of his plays, it’s possible convincingly to map onto them the now conventional three act structure.

The three act structure.

The three-act structure can simply and unexceptionally be understood as the beginning, the middle and the end.  It is in act one that the nature of the conflict is established and the identities of the protagonist and antagonist are revealed (or in the case of the latter, at least alluded to.  During the second act, difficulties will arise, these the dramatic device which seem to create the insurmountable obstacle which much defeat the protagonist.  In the third act, there will be a climax (and perhaps anti-climaxes), the point at which all seems finally lost for the protagonist.  However, despite it all, the protagonist prevails and, even if they die, the circumstances will be such that resolution attained is sufficient to satisfy the moral point to be made.

F Scott Fitzgerald with wife Zelda (Zelda Sayre, 1900-1948).

F Scott Fitzgerald’s (1896–1940) oft-quoted phrase “there are no second acts in American lives” appears as a fragment in his posthumously published, unfinished novel The Last Tycoon (1941) but he first published it in the early 1930s in the essay My Lost City, a kind of love letter to New York.  The quote is frequently misunderstood as an observation that for those Americans who suffer disgrace or destitution, there is no redemption, no coming back.

However, from politics to pop culture, there are many examples of temporarily disreputable Americans resurrecting their public lives from all but the most ignominious opprobrium.  Fitzgerald was a professional writer and his observation was an allusion to the structure used by playwrights in traditional three-act theater: (1) problem, (2) complication & (3) solution.  He thought the nature of the American mind was to prefer to skip the second act, going straight from a problem to finding a solution.  His point was well-made and it’s one of the themes of the narrative which underlies the discussions (which became arguments and sometimes squabbles) of military and political strategy between Washington and London during the Second World War.

Pre 1000: From the Middle English buterflie, butturflye & boterflye, from the Old English butorflēoge, buttorflēoge & buterflēoge.  It was cognate with the Dutch botervlieg and the German Butterfliege (butterfly).  The construct was (with variations was butere (butter) +‎ fly.  Etymologists note alternative origins for the name.  Either (1) it was first applied to creatures with wings of a notably yellowish hue (perhaps the dominant or single species of the type in an area) or (2) as a response to the belief that butterflies ate milk and butter or (3) the first element may have originally been butor- (beater), a mutation of bēatan (to beat), a reference to the movement of the wings.  The idea of the fragile things as thieves of milk and butter is supported by similar instances in other European languages including the German Molkendieb (butterfly (literally “whey thief”) and the Low German Botterlicker (butterfly (literally butter-licker) & Bottervögel (butterfly (literally “butter-fowl”).  There was also the notion they excreted a butter-like substance, memorably expressed in the Dutch boterschijte (butterfly (literally “butter-shitter”).  Most memorable however is the explanation in the tales of the Brothers Grimm (die Brüder Grimm, Jacob (1785–1863) and Wilhelm (1786–1859)) in which witches disguised themselves as butterflies.  The early forms in Middle English superseded the non-native Middle English papilion (butterfly) borrowed from the Old French.  Butterfly is a noun & adjective, butterflied is a verb & adjective and butterflying is a verb.  The noun plural is butterflies.

Butter was from the Middle English buter & butter, from the Old English butere, from the Proto-West Germanic buterā, from the Latin būtȳrum, from the Ancient Greek βούτῡρον (boútūron) (cow cheese), the construct being βοῦς (boûs) (ox, cow) + τῡρός (tūrós) (cheese).  Fly was from the Middle English flye & flie, from the Old English flȳġe & fleoge (a fly, a winged insect), from the Proto-Germanic fleugǭ (a fly) & fleugon (flying insect), from the primitive Indo-European plewk- (to fly).  It was cognate with the Scots flee, the Saterland Frisian Fljooge, the German Low German Fleeg, the Danish flue, Norwegian Bokmål flue & Norwegian Nynorsk fluge, the Swedish fluga and the Icelandic fluga, the Old Saxon fleiga, the Old Norse fluga, the Middle Dutch vlieghe, the Dutch vlieg, the Old High German flioga and the German Fliege (fly (literally "the flying (insect))).  The Old English fleogende (flying) was from the primitive Indo-European root pleu- (to flow).

Butterfly was applied first to people circa 1600, originally in reference to vain and gaudy attire, an allusion to the butterfly’s colors.  By 1806 it had become a class-based put-down referencing a transformation from a lowers social class to something better, invoking the idea of progression from sluggish caterpillar to graceful butterfly (essentially a synonym for bounder).  The reference to flitting tendencies (from one interest, occupation etc) dates from 1873 and the social butterfly (one who moves effortlessly between social encounters and events) emerged in the 1920s.  The swimming stroke was first defined in 1935.  As a general descriptor (butterfly agave, butterfly ballot, butterfly fish, butterfly flower, butterfly plant, butterfly bomb, butterfly keyboard, butterfly chair, butterfly ray, butterfly shell et al), it’s applied wherever the resemblance to the open wings appears compelling.

Native to the forests of Central and South America, the Blue Morpho is one of the world’s largest butterflies. The wings are bright blue with lacy black edges, the result of light reflecting off microscopic scales on the back of their wings.  Lovely though the blue appears, it’s often not seen because the underside of this butterfly’s wing is a dull brown which provides a camouflage against predators.  When the wings are closed as the Blue Morpho sits on a tree, it blends in well.

Anatomy of the butterfly valve (left), butterfly crochet (centre) & butterfly bandage (right).

Butterfly valves came into use in the late 1700s and have been popular since for their ease of manufacture, simplicity of operation and low maintenance.  The butterfly nut appeared in 1869 although in some markets it usually called the wing nut; interestingly, the similar fastener with a male thread is known as a wing screw or wing bolt but apparently never a butterfly screw or bolt, presumably because the delicate butterfly is thought emblematically female.  The phrase “Who breaks a butterfly upon a wheel?” is from Alexander Pope's (1688-1744) Epistle to Dr Arbuthnot" (1735).  The allusion is to "breaking on the wheel", a form of torture in which victims had their long bones broken by an iron bar while tied to a Catherine wheel, the idea a critique of excessive effort or deployment of resources to solve a simple problem; the less confronting phrase “sledgehammer to crack a nut” means the same thing.  The phrase “butterflies in the stomach” is a descriptive reference to the mild stomach spasms induced by anxiety and dates from 1908.  The butterfly effect is the most celebrated idea from (the somewhat misleadingly named) chaos theory, introduced in the 1972 paper Predictability: Does the Flap of a Butterfly's Wings in Brazil Set Off a Tornado in Texas? by US academic meteorologist Edward Lorenz (1917–2008).  Lorenz had developed the theory based on his observations in the early 1960s (in one of the earliest big-data models) that a tiny change in one variable (one of a dozen numbers representing atmospheric conditions) had an extraordinary effect upon long-term outcomes.

The use of the butterfly motif in industrial design in 1967 became a footnote in legal history in the trial of the boxers Rubin "Hurricane" Carter (1937–2014) & John Artis (1946-2021 for a triple murder committed at the Lafayette Bar and Grill in Paterson, New Jersey.  Evidence presented by the prosecution claimed that witness descriptions of the getaway car matched the hired car Carter was found driving in the vicinity of the Lafayette immediately after the killings, their statements even including a mention of the distinctive butterfly-shaped taillight chrome.  However, although a witness said the rear lights lit up across the back of the getaway car, the taillights on Carter's Dodge Polara, although there was certainly a butterfly chrome surround, lit up only at the edges; it was the more expensive Dodge Monaco which had the extended lights.  In the ever changing swirl of model names and trim levels which characterized the US industry during its golden age (1955-1973), in 1966 the Polara was Dodge’s entry-level full-size model, above which sat the higher-priced Polara 500, Monaco, and Monaco 500.  For some reason (and this was not unusual), the lineup’s nomenclature in Canada differed, being Polara, Polara 440, Polara 880, and Monaco.  In both markets however, it was only the Monaco which featured the extended tail lamps.

On a dark night, glimpsed by a traumatized witness for a second or two, that may have not been significant because tests did reveal the reflective silver finish on the Polara’s rear panel did indeed appear red at certain angles when the brake lights were activated but the distinction, along with a witness’s correction of this in the 1976 re-trial did lead some to suggest the police might have been coaching witnesses; “hardening the statement” in law enforcement lingo.  That actually aligned with the evidence provided by another witness and the prosecution would later suggest later suggested the confusion was caused by the defense misreading the court transcript.

Butterfly doors are used on some high-performance cars and not wholly as a gimmick, the advantage being that in such usually low-slung vehicle, they do make entry and exit somewhat easier that scissor doors.  There’s even more functionally on certain competition cars because (1) they allow the carefully-crafted aerodynamics of the canopy to be preserved, (2) the driver can enter and leave the cockpit more quickly and (3) the design allows the structural integrity of the shell to be maximized.  Butterfly doors open upwards and outwards and in that they differ from scissor doors which are hinged to move only upwards, thus offering the possibility of a greater aperture while demanding more lateral clearance.  Exotic doors were seen in a handful of pre-war cars, none of which reached production, but it was the Mercedes-Benz 300SL (W194) race-car of 1952 which brought to public attention the idea car doors could be something different.  Such was the response that the factory used the gull-wing doors when, in 1954, the 300SL (W198) was offered in a road-going version although the engineering, like the concept, was not new, having before been used in both marine architecture and aircraft fuselages.  Similarly, the design elements which underlie butterfly and scissor doors can be found in buildings and machinery dating back in some cases centuries but of late, all have come most to be associated with exotic cars.

1967 Alfa Romeo 33 Stradale

Variations on the theme had appeared on the show circuit for some time before butterfly doors debuted on the Alfa Romeo 33 Stradale in 1967 which was much admired but it was thought the complexity of such things would limit their use to low volume runs such as the Stradale (of which only 18 were built) or one-off styling exercises such as the Alfa Romeo Carabo (1968) which used scissors.  However, scissor doors appeared on the prototype Lamborghini Countach (LP500) and, despite the doubts of some, were retained when the production version was released in 1974.  Since then, gull-wings (which open upward on a horizontal axis, hinged from the roof), scissors (which open upwards, rotating on a horizontal axis, hinged from the front), butterflies (which open upwards and outwards on an axis unaligned to the vertical or horizontal, hinged from the A (windscreen) pillar and dihedrals (scissors which move laterally while rotating ) have become common (relatively speaking) and designers seem intent on adding some new twist which seem sometimes to add no advantage but usually attract publicity (admittedly an advantage in the abstract), the most complex to date being the dihedral synchro helix doors which open forward, slide forward and rotate up.

Mercedes-Benz McLaren SLR Coupé & Roadster (top) and McLaren MP4-12C Coupé & Spider (bottom).

When Mercedes-Benz released the SLR McLaren (2003-2009), in an attempt to make explicit the link with the 300SL, they laid it on with a trowel, the phrase “gullwing doors” appearing in the factory’s original press release no less than seven times, just in case people didn’t get the message.  Nobody was fooled and they’ve always been called butterflies.  One clever piece of engineering was seen when the SLR roadster was released, those butterfly doors made possible by using hinge points along the rather than at the top.  McLaren used a variation of this idea when it released the McLaren MP4-12C (2011-2014), omitting the top hinge which allowed the use of frameless windows even on the roadster (spider).

IBM's ThinkPad 701 series was available during 1995 and was that year's biggest seller in its class, its distinctive feature the "butterfly" keyboard, a design in response to the obviously contradictory demands that laptops be smaller and lighter while still equipped with keyboards big enough comfortably to be used (especially with the big, clumsy fingers of men).  The 701 was marketed in what was then an untypically IBM manner, newspaper advertisements in the run-up to the launch published with nothing but a butterfly in the corner, the IBM logo later added while a few days before the debut, the text "Watch for the announcement" appeared.  Butterfly had actually been the project's internal codename although it had never been intended for use as a product, apparently because IBM's corporate policies didn't permit the use of the names of living.  Still, the use in the teaser advertisements did suggest they planned it to catch on as a nickname and doubtlessly hoped for a better outcome than the last time a codename was picked-up, the unfortunate "peanut" (the PCjr (1984-1985)) not fondly remembered.

The 701 series, some models even offering a dual-boot into OS/2 Warp (3.0), was well-received and the butterfly keyboard much admired.  The main body of the keyboard was a two-piece construction, which, gear-driven by the movement of the lid, spread apart to become a single unit as the laptop was opened, the process reversed as the lid closed.  IBM actually called it the TrackWrite, but it was universally known as the butterfly and so compelling was the design that to this day, one is on permanent display in Manhattan's Museum of Modern Art (MoMA).  Popular though it was, the market moved and the place on the demand curve at a price point which interested IBM was for laptops with larger screens so the need for the butterfly technology vanished, the 701 remaining unique.  Some patents have recently been filed which suggest manufacturers may be planning to release another laptop with a butterfly keyboard but, in an age of ultra-thin devices, it will presumably be a thing of low-tactility and thus lacking the responsiveness which had been one of the most attractive features of the original.

1651 (in English use): From the Late Latin Bȳzantīnus (of Byzantium), the name derived ultimately from the ancient Greek city Byzantion on the Bosporus and the Sea of Marmara, said to have been named in 657 BC for it founder, Byzas of Megara.  Constantine I (circa 272–337; Roman emperor 306-337 (and the first to convert to Christianity) rebuilt the city and renamed it Constantinople.  The city fell to the Ottoman Turks in 1453 although the modern-day name Istanbul wasn’t (except in the Vatican and the Orthodox Church) universally adopted until the years after World War II (1939-1945).  Although in Greek legend the ancient city name Byzantion came from King Byzas, leader of the Megarian colonists, who is said to be its founder, the etymology remains uncertain although most historians of the period seem to agree it must be of Thraco-Illyrian origin and there’s no doubt Byzantium is a Latinization of the original.  Centuries later, in Western literature, the name Byzantium became the standard term with which to refer to the Eastern Roman Empire (the "Byzantine Empire” centred on the walled capital Constantinople.  For all the generations which lived while the empire stood, the term would have been mysterious and it gained currency only after 1555 when introduced by the German historian Hieronymus Wolf (1516-1580), a century after Constantinople had fallen and the empire had ceased to exist.  Until Wolf introduced the phrase, the word Byzantium was restricted to just the city, rather than the empire which, in the way of such things, had waxed and waned.  Byzantine is a noun & adjective; the noun plural is Byzantines.

Standing for centuries on blood-soaked soil on the Bosporus where Europe ends and Asia begins, Greek forces laid siege during the Peloponnesian war and Sparta took the city in 411 BC before it was reclaimed by the Athenian military in 408 BC.  Almost razed, by Roman forces in 196 AD, Byzantium was rebuilt by Septimius Severus (145-211; Roman emperor 193-211) and quickly regained its previous prosperity.  The location of Byzantium attracted Constantine I (circa 272–337; Roman emperor 306-337 (and the first to convert to Christianity)) who in 330 AD re-created it as an imperial residence inspired by Rome itself and after his death, it was called Constantinople (Κωνσταντινούπολις (Konstantinoupolis (literally "city of Constantine"))).  For a thousand years, it was the capital of the Eastern Roman Empire and a commercial, cultural & diplomatic centre and from its strategic position, Constantinople’s rulers controlled the major trade routes between Asia and Europe, as well as the passage from the Mediterranean to the Black Sea.  On 29 May 1453, in the first example of a major city falling to a siege by artillery, Constantinople fell to the Turks, becoming the capital of the Ottoman Empire.  The great walls which for centuries had defied invaders from land and sea, crumbled to modern cannon fire.  Even then, the Turks called the city Istanbul (from the Greek eis-tin-polin (to-the-city) although it was not officially renamed until 1930, almost a decade after the Empire was dissolved and it remains Turkey’s largest and most populous city, although Ankara is now the national capital.

The other senses of byzantine (as often used without the initial capital): (1) “characterized by a devious and usually surreptitious manner of operation, often for some nefarious purpose” and (2) “something intricate, complicated; inflexible, rigid, unyielding” are both of dubious historical validity.  According to the Oxford English Dictionary (OED), “byzantine” was first used in English in 1937 (of the impenetrable despotism of the Soviet Union which appeared to those in the Foreign Office schooled in the classics to be much the same as what they’d learned of the antics practiced in Constantinople) in the sense of “reminiscent of the manner, style, or spirit of Byzantine politics; intricate, complicated; inflexible, rigid, unyielding” but in French political scientists had earlier applied in the same figurative context, something which would surprise few familiar with the politicians of inter-war France, a generally rotten crew about whom it was remarked “they can’t keep a government for nine months, nor a secret for five minutes”.  Still, it was probably the English who lent the word its loaded meaning.  Edward Gibbon’s (1737–1794) magisterial The History of the Decline and Fall of the Roman Empire (six volumes: 1776-1788) was influential for generations in forming the construct of the period in the European imagination and he caricatured the history of the empire as endless chicanery, shadyness, back-channel deals, low skulduggery, back-stabbing, and naked grabs for power.  Until late in the twentieth century, phrases like “bewildering Oriental intrigue” flowed easily from the pens of English historians and hints of the attitude, cloaked in wokish words, appear even since they’ve switched to keyboards.  Much modern scholarship though has been more forgiving and there’s now an understanding that while like everywhere, low politics and dirty deeds were sometimes done, a remarkable civilization grew on the Bosporus.

The association with needless complexity and pointless administrative duplication was probably born of the same prejudices to which was added the view the empire was infused with strange religious rituals and stubbornness in the way it clung to superstition.  Historians have of late have refined this view, suggesting words like “intricate” or even “labyrinthine” might better capture the spirit of the place which was, by any standards and certainly those of medieval Europe, a complex and highly developed society.  The loaded meaning though seems here to stay, perhaps reinforced in the public imagination by the phonetic similarity between “byzantine” & “bizarre”.  Bizarre means “strangely unconventional; highly unusual and different from common experience, often in an extravagant, fantastic or conspicuous ways” and was from the French bizarre (odd, peculiar (and formerly “brave; headlong, angry”), either from the Basque bizar (a beard (on the notion that bearded Spanish soldiers made a strange impression on the French) or from Italian bizzarro (odd, queer, eccentric, weird (and, of a horse “frisky” in the sense of the English “bolter”)) of unknown origin but thought probably related to bizza (tantrum), which may be of Germanic origin.  In summary then, the Byzantines would have had their moments but were no more nasty and duplicitous that politicians everywhere and when describing convoluted things as byzantine it might be more accurate to instead call them labyrinthine or just bizarre.
