1350–1400: From the Middle English graund, grond, grand, graunt & grant, from the Anglo-Norman graunt, from the Old French grant & grand (large, tall; grown-up; great, powerful, important; strict, severe; extensive; numerous), from the Latin grandis (big, great; full, abundant; full-grown (and figuratively “strong, powerful, weighty, severe”, of unknown origin.  Words conveying a similar sense (depending on context includes ambitious, awe-inspiring, dignified, glorious, grandiose, imposing, large, lofty, luxurious, magnificent, marvelous, monumental, noble, princely, regal, royal, exalted, palatial; brilliant, superb opulent, palatial, splendid, stately, sumptuous, main, large, big & august.  Grand is a noun & adjective, grander & grandest are adjectives, grandness is a noun and grandly is an adverb; the noun plural is grands.

In Vulgar Latin it supplanted magnus (although the phrase magnum opus (one’s great work) endured) and continued in the Romanic languages.  The connotations of "noble, sublime, lofty, dignified etc” existed in Latin and later were picked up in English where it gained also the special sense of “imposing” (which tended often to imply “big”.  The meaning “principal, chief, most important” (especially in the hierarchy of titles) dates from the 1560s while the idea of “something of very high or noble quality” is from the early eighteenth century.  As a general term of admiration (in the sense of “magnificent or splendid” it’s documented since 1816 but as a modifier to imply perhaps that but definitely size, it had been in use for centuries: The Grand Jury was an invention of the late fifteenth century, the grand tour was understood as “an expedition around the important places in continental Europe undertaken as part of the education of aristocratic young Englishmen) as early as the 1660s and the grand piano was named in 1797.  In technical use it was adapted for use in medicine as the grand mal (convulsive epilepsy with loss of consciousness), borrowed from the French grand mal (literally “great sickness”) as a point of clinical distinction from the petit mal (literally “small sickness”) (an epileptic event where consciousness was not lost).  The meaning "a thousand dollars" dates from 1915 and was originally US underworld slang, that sum then a lot of money (the cheapest Ford Model T then listed for US$350).

The “Twenty Grand”: 1933 Duesenberg SJ Arlington Torpedo Sedan by Rollston.

Celebrating "A century of Progress" and held between 27 May, 1933-31 October, 1934 in Chicago, Illinois, the Chicago World's Fair was memorable for the stunning array of art deco architecture and being the first US-staged international fair to book a profit.  Indeed, with close to 40 million paying visitors, the event had proved so popular the scheduled closing date of 12 November, 1933 was extended by almost a year.  When the fair opened its gates, the nation still was in the depths of the Great Depression and it was less than three months since Franklin Roosevelt (FDR, 1882–1945, POTUS 1933-1945) in his first Inaugural Address on 4 March 1933 had delivered the words “…the only thing we have to fear is fear itself.” so, in the circumstances, after three troubled years, the success was a remarkable achievement.  Still, it was far from an ideal time to display luxury goods but despite it all, four of the nation’s most exalted automobile manufacturers showed the finest they could achieve.

The “Twenty Grand”: 1933 Duesenberg SJ Arlington Torpedo Sedan by Rollston. 

Reflecting the interest in what the industry then called “streamlining”, Cadillac showcased their Aerodynamic Coupe, a fine housing for the company’s already famous 452 cubic inch (7.4 litre) V16.  Visually, Packard’s Sport Sedan didn’t have the Cadillac’s radical lines but the coachwork by Dietrich was elegant with some styling elements which others would emulate over the remainder of the decade.  Powered by Packard’s second-generation V12, the press dubbed it “The Car of the Dome” an allusion to the exposition’s Travel and Transportation Building where it sat.  Most startling among the four was Pierce-Arrow’s Silver Arrow, the look of which often is described as “avant-garde” but in many aspects it anticipated the early days of mid-century modernism and was probably an influence on the remarkable Tatras from Czechoslovakia although, with a front-mounted V12, under the striking bodywork, it was in many ways a conventional design.  By far the most familiar in appearance was the Duesenberg Arlington Torpedo Sedan with one-off coachwork by Rollston.  While it lacked the rakish appeal of some of the Duesenberg roadsters or phaetons, of its type it was a fine expression and under the long hood of course sat the supercharged 420 cubic inch (6.9 litre) straight-8; with a 32 valve, DOHC (double overhead camshafts) cylinder head, it was rated at 320 HP and was the industry’s most powerful engine.  Although not officially revealed, rumors circulated the price tag was US$20,000 (equivalent to some US$500,000 in 2026), leading the press to nickname it the “Twenty Grand.”

The use of the prefix grand- in genealogical compounds is a special case.  The original meaning was “a generation older than” and the earliest known reference is from the early thirteenth century in the Anglo-French graund dame (grandmother) & (later) grandsire (grandfather), etymologists considering the latter possibly modeled on the avunculus magnus (great uncle).  The English grandmother & grandfather formally entered the language in the fifteenth century and the extension of the concept from “a generation older than” to “a generation younger than” was adopted in the Elizabethan era (1558-1603) thus grandson, granddaughter etc.  Grand as a modifier clearly had appeal because in the US, the “Big Canyon” was in 1869 re-named the Grand Canyon.  In the modern era grand has been appended whenever there’s a need economically to convey the idea of a “bigger or more significant” version of something thus such constructions as grand prix, grand slam, grand larceny, grand theft auto, grand unification theory, grand master (a favorite both of chess players and the Freemasons) etc.  While “grand” can be a “loaded word” in that it can be deployed to convey something positive or negative some related forms can be even more variable and often are prone to misuse.  These include “grandeur” ((1) the state of being grand or splendid; magnificence; (2) the state of being noble; (3) largeness; tallness; loftiness (archaic), “grandiose” ((1) Large and impressive, in size, scope or extent; (2) pompous or pretentious; (3) magnificent or spectacular and “grandiloquent” (of an individual, their writing or speech): given to using language in a showy way by using may obscure or long words.

The Grand Jury

Donald Trump in Manhattan Criminal Court, April 2022.

The Manhattan grand jury that indicted Donald Trump (b 1946; POTUS 2017-2021 and since 2025) on 34 felony counts of "falsification of business records in the first degree" was an example of an institution with origins in twelfth century England although it didn’t generally become known as the “grand jury” until the mid-1400s.  At least some of the charges against Mr Trump related to the accounting associated with “hush-money” payment made in some way to Stormy Daniels (b 1979; the stage name of Stephanie Gregory although Mr Trump prefers “horseface” which seems both ungracious and unfair) and reports at the time offered the prospect of more legal-political drama, the suggestion he'd likely have to face more grand juries hearing more serious matters.  All such possibilities were however put on hold when he again became POTUS. 

A grand jury is a group of citizens (usually between 16-23) who review evidence presented by a prosecutor to determine whether the case made seems sufficiently compelling to bring criminal charges.  A grand jury operates in secret and its proceedings are not open to the public, unlike a trial before a jury (a smaller assembly and classically a dozen although the numbers now vary and once it was sometimes called a petit jury (petit (small), from the Middle English petit, from the Old French petit, from the Late Latin pitittus, a diminutive of pit-).  It is this smaller jury which ultimately will pronounce whether a defendant is guilty or not; all a grand jury does is determine whether a matter proceeds to trial in which case it will issue an indictment, which at law is a formal accusation.  The origins of the grand jury in medieval England, where it was used as a means of investigating and accusing individuals of crimes was to prevent abuses of power by the king and his appointed officers of state although it was very much designed to protect the gentry and aristocracy from the king rather than any attempt to extend legal rights to most of the population.

The grand jury has been retained in the legal systems of only two countries: the US and Liberia.  Many jurisdictions now use a single judge or magistrate in a lower court to conduct a preliminary hearing but the principle is the same: what has to be decided is whether, on the basis of the evidence presented, there’s a reasonable prospect a properly instructed (petit) jury would convict.  In the US, the grand jury has survived because the institution was enshrined in the Fifth Amendment to the Constitution: “No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger.”  In England, the grand jury was thought a vital protection against arbitrary prosecutions by the government, and it was included in the Bill of Rights (1689) to ensure individuals would not be subject to unjustified criminal charges.  There is an argument that, by virtue of England’s wondrously flexible unwritten constitution, the grand jury hasn't been abolished but they're merely no longer summoned.  It's an interesting theory but few support the notion, the Criminal Justice Act (2003) explicitly transferring the functions to the CPS (Crown Prosecution Service) and the model of the office of  DPP (Director of Public Prosecutions) has been emulated elsewhere in the English-speaking world.  Presumably, a resuscitation would require the DPP to convene a grand jury and (if challenged on grounds of validity) the courts have to concur but as late as 1955 an English court was prepared to hold a court which had for centuries neither sat nor held a hearing remained extant so the arguments would be interesting.

The “Grand Mercedes”: The Grosser tradition

Der Grossers: 1935 Mercedes-Benz 770 K (W07) of Emperor Shōwa (Hirohita, 1901–1989, emperor of Japan 1926-1989 (left)), Duce & Führer in 1939 Mercedes-Benz 770 K (W150) leading a phalanx of Grossers, Munich, 1940 (centre) and comrade Marshal Josip Broz Tito (1892–1980) in 1966 Mercedes-Benz 600 six-door Landaulet (W100), Belgrade, 1967 (right).

Produced in three series (770 K (W07, 1930–1938 & W150, 1939-1945) & 600 (W100, 1963-1981)) the usual translation in English of “Grosser Mercedes” is “Grand Mercedes” and that is close to the German understanding which is something between “great”, “big” and “top-of-the-line”.  In German & Austrian navies (off & on) between 1901-1945, a Großadmiral (Grand Admiral) was the equivalent to the (five star) Admiral of the Fleet (UK) or Fleet Admiral (US); the rank was abolished in 1945 and has never been re-established.  When the 600 was released in 1963, it may have been the last time a single model could be described as "the best car in the world" but, driven to extinction in 1981 by an oil crisis and an array of regulations never envisaged when it was designed, it wasn’t replaced and the factory didn’t return to the idea until a prototype was displayed at the 1997 Tokyo Motor Show.  The specification and engineering was impressive but the appearance was underwhelming, a feeling reinforced when the production version (2002-2013) emerged not as an imposing Grosser Mercedes but a Maybach, a curious choice which seemed to suggest a marque which for a century had been the choice of popes, presidents & potentates was no longer good enough.  Although dynamically a fine car (at the time the best of its type), the Maybach looked something like a big Hyundai and lingered for a slow-selling decade before an unlamented death, suggesting the MBAs (Master of Business Administration) who decided on a re-branding using a name with little resonance except among except automotive & military historians should stick to creating campaigns for washing powder.

Grand, Grand Luxe & Gran

Jaguar 420G publicity material, 1966.

Car manufacturers were attracted to the word because of the connotations (bigger, better, more expensive etc).  When in 1966 Jaguar updated the slow-selling Mark X (1961-1966), it was integrated into what proved a short-lived naming convention, based on the engine displacement.  Under the system, with a capacity of 4.2 litres (258 cubic inch) the thing had to be called 420 but there was a smaller saloon in the range so-named so the bigger Mark X was renamed 420G.  Interestingly, when the 420G was released, any journalist who asked was told “G” stood for “Grand” which is why that appeared in the early reports although the factory seems never officially to have used the word, the text in the brochures reading variously: 420G, 420 G or 420 “G”.  The re-naming did little to encourage sales although the 420G remained in production until 1970 by which time production had dwindled to a trickle, the car rendered instantly a relic when the epoch-making XJ6 (in three generations, 1968-1992) made its debut in 1968.  The use of a "G" is unusual in product names although it has appeared as a part of alphabetical sequences (bras and certain Chryslers for example) but when in 1989 the now defunct software manufacturer Lotus released a version of their 1-2-3 spreadsheet for IBM's new OS/2 operating system, it was called 1-2-3/G, the "G" a nod to the product using OS/2's Presentation Manager (a GUI (Graphical User Interface)).  Lotus 1-2-3 was one of the PC (personal computer) industry's original "killer apps" and along with WordPerfect & dBASE III was the backbone of corporate software in the 1980s but the universe shifted and all are now historic footnotes.  As IBM had for OS/2, Lotus had grand plans for 1-2-3/G but both fell victim to Microsoft's better implemented strategy for global domination.   

The tale of the Mark X & 420G is emblematic of the missed opportunities and mismanagement which would afflict the British industry during the 1970s & 1980s.  In 1961, the advanced specification of the Mark X (unitary construction, independent rear suspension, four-wheel disc brakes) made it an outstanding platform and had Jaguar fitted an enlarged version of the larger of the two superb V8s they had gained with their purchase in 1960 of Daimler, it would have been an ideal niche competitor in mid-upper reaches of the lucrative US market.  Except for the engine, it needed little change except better ventilation and the installation of a good air-conditioning system, then already perfected by Detroit.  Although the Daimler V8 and Borg-Warner gearbox couldn't have matched the ultimate refinement of what Detroit was building (by then the finest engine-transmission combinations in the world), the English pair certainly had their charms and would have seduced many.

1969 Pontiac Grand Prix SJ 428.  The use of "SJ" was a borrowing from the celebrated Duesenberg SJs (1932-1937) a breed that exerted an influence well beyond the three dozen built.

Pontiac’s memorable 1969 Grand Prix also might have gained some allure from the word.  The term “Grand Prix” still is most associated with top-level motorsport (although it originally was borrowed from Grand Prix de Paris (Big Prize of Paris), a race for thoroughbred horses staged at the Longchamps track) so although Pontiac’s rather large 1962 Grand Prix was far removed from a racing car, it was marketed on the basis of “high performance” so the tag would have made sense given the way labels were applied in the era.  However, big as it was, it got bigger and the second generation (1965-1968) morphed into something truly grand in size if not dynamic qualities.  Style returned when the third generation (1969-1972) was released, the look dominated by the elongated nose that truly was a triumph of fashion over function; although fitted with V8 engines with displacements as large as 455 cubic inches (7.5 litre), the power-plants, while relatively wide, were quite short and under that long hood (bonnet) was a compartment that easily could have housed a V16.  As a piece of packaging efficiency it was an absurdity but undeniably it was a dramatic look and sales spiked.  The 1969-1970 cars remain the most highly regarded of the third generation, the few hundred with the 428 cubic inch (7.0 litre) HO (High Output) V8 coupled with a four-speed manual transmission the most collectable.  From there, although over a further five generations the Grand Prix remained successful enough to remain in the catalogue until 2008, the best years were over and at some point in the 1970s or 1980s (opinions differ), there was little about the by then dreary Grand Prix which seemed at all grand.

Although a bit deluxe, not especially grand: 1980 TF (Mark V) Ford Cortina GL.

During the interwar years (1919-1939) “deluxe” (borrowed from the world of fashion) found to be a good label to apply to a car with bling added and sold for a premium well beyond what the adornments cost; the concept proved so profitable it remains practiced to this day.  Deluxe (sometimes as De luxe) was a commercial adaptation of the French de luxe (of luxury), from the Latin luxus (excess), from the primitive Indo-European lewg- (bend, twist).  The “deluxe” label worked so well it begat “Super Deluxe” & “Grand Luxe” both genuinely coinings of the industry.  Deluxe and Grand Luxe eventually fell from favour as model names for blinged-up creations became more inventive but the initializations L, DL & GL were adopted by some, the latter surviving longest by which time it was understood to signify just something better equipped and thus more expensive; it’s doubtful many made a literal connection to “Grand Luxe”.

1970 Plymouth Barracuda Gran Coupe Convertible in Plum Crazy (FC7).

A linguistic curiosity of the US motor industry in the 1970s was “Gran”, technically a truncation of “grand” but with no connection with “gran” as an affectionate diminutive of “grandmother” or the many uses (as Gran) as a proper noun (surnames, locality names etc).  It was Chrysler’s Plymouth Division that for years championed “Gran” (though Buick used it too) and while the Gran Fury (1980-1989) was the longest serving, more linguistically interesting were the “Gran Coupe” (1970-1971) versions of the third generation (1970-1974) Barracuda and the 1971 Fury III Gran Coupe.  The Barracuda Gran Coupe was a bit of mission creep for the word “coupe” because the model was available as both a two-door hardtop and a convertible (in 1970 only).  That was at the time unusual but not wholly without (a partial) precedent because for generations English manufacturers had referred to their larger convertibles as DHCs (drophead coupé).

1971 Plymouth Fury III Gran Coupe (which was a four-door hardtop).

However, the 1971 Fury III Gran Coupe was in the US a genuine first because it had four doors.  The notion of a “four-door coupé” was not new because in the UK, Rover (a company with a history of adventurism in engineering which belied its staid image) in 1962 released a pillared version of the 3 Litre (P5, 1958-1967) four-door saloon with a lowered roof-line and some different interior fittings; this they named “3 Litre Coupé” which puzzled those who had become used to the designation being applied to two-door machines but etymologically, Rover was correct.  Coupé was from the French coupé, an elliptical form of carosse coupé (cut carriage), past participle of couper (to cut)).  Rover did cut-down the roof of the P5 so that was consistent with the etymology but shamelessly, Plymouth, which in 1970 had offered (an uncut) two door Fury II Gran Coupe, for 1971 introduced (the uncut) Fury III Gran Coupe with four door hardtop bodywork.  So, there are (uncut) four door coupes because Plymouth said so.  The mysterious “Gran” seems to have been used for no reason other than sounding vaguely “European” and therefore imparting a more “upmarket” image than the by then common “Grand”.  It was at the time a trend which saw the adoption of “Brougham”, “Monaco”, “Cordoba”, “Monte Carlo”, “rich Corinthian leather” and such although the brutish “Grand” would make a comeback when Plymouth turned to making people movers (vans with more seats).

In the matter of Grand Theft Auto (GTA5): Lindsay Lohan v Take-Two Interactive Software Inc et al, New York Court of Appeals (No 24, pp1-11, 29 March 2018)

In a case which took an unremarkable four years from filing to reach New York’s highest appellate court, Lindsay Lohan’s suit against the makers (Take-Two, aka Rockstar) of the video game Grand Theft Auto V was dismissed.  In a unanimous ruling in March 2018, six judges of the New York Court of Appeals rejected her invasion of privacy claim which alleged one of the game’s characters was based on her.  The judges found the "actress/singer" in the game merely resembled a “generic young woman” rather than anyone specific.  Unfortunately the judges seemed unacquainted with the concept of the “basic white girl” which might have made the judgment more of a fun read.

Beware of imitations: The real Lindsay Lohan and the GTA 5 ersatz, a mere "generic young woman".

Concurring with the 2016 ruling of the New York County Supreme Court which, on appeal, also found for the game’s makers, the judges, as a point of law, accepted the claim a computer game’s character "could be construed a portrait", which "could constitute an invasion of an individual’s privacy" but, on the facts of the case, the likeness was "not sufficiently strong".  The “…artistic renderings are an indistinct, satirical representation of the style, look and persona of a modern, beach-going young woman... that is not recognizable as the plaintiff" Judge Eugene Fahey (b 1951) wrote in his ruling.  Judge Fahey's words recalled those of Potter Stewart (1915–1985; associate justice of the US Supreme Court 1958-1981) when in Jacobellis v Ohio (378 U.S. 184 (1964) writing of the concept of "obscenity" he wrote: “I shall not today attempt further to define… and perhaps I could never succeed in intelligibly doing so.  But I know it when I see it…”  Judge Fahey knew a basic white girl when he saw one; he just couldn't name her.  Lindsay Lohan's lawyers did not seek leave to appeal.

The game’s developers may have taken the risk of incurring Lindsay Lohan’s wrath and indignation because they’d been lured into a false sense of security by crooked Hillary Clinton (b 1947; US secretary of state 2009-2013) not filing a writ after a likeness of her appeared on GTA 4’s (2008) Statue Of Happiness which stands on Happiness Island, just off the coast of Liberty City.  The Statue of Happiness was a blatant knock-off of New York’s Statue of Liberty and crooked Hillary became a determined and acerbic critic of Rockstar and the GTA franchise when details of the “Hot Coffee affair” were revealed.  That controversy arose after modders promulgated a code which in GTA: San Andreas’ release (2004) unlocked a hidden “mini-game” which allowed players to control explicit on-screen sex acts.  Men having sex (however defined) with women with whom they don’t enjoy benefit of marriage was a bit of a sore point with crooked Hillary, then a US senator (Democrat-New York), who embarked on a campaign for new regulations be imposed on the industry and the most immediate consequence was the ESRB (Entertainment Software Rating Board) launching an investigation, subsequently raising GTA: San Andreas’s rating from “M” (Mature) to “AO” (Adults Only, 18+) until the objectionable content was removed.  For those who wondered if the frankly frightening visage on the GTA 4 statute really was what some suspected, the object’s file name was “stat_hilberty01.wdr”.

Rockstar's Statue Of Happiness in GTA 4 (2008, left) and an official photograph of crooked Hillary Clinton (right). 

Rockstar seeking vengeance was understandable because crooked Hillary’s moral crusade proved tiresome for the company.  Once the ESRB had been nudged into action, crooked Hillary petitioned the FTC (Federal Trade Commission) to (1) find the source of the game's “graphic pornographic and violent content”, (2) determine if it should be slapped with an AO rating and (3) “examine the adequacy of the retailers' rating enforcement policies.”  Not content, she then announced she’d be sponsoring in the Senate a bill for an act to make it a federal crime (with a mandatory US$5,000 fine) to sell to anyone under 18, violent or sexually explicit video games; the FEPA (Family Entertainment Protection Act) was filed on 17 December, 2005 and referred to the Committee on Commerce, Science and Transportation, where quietly it was allowed to expire, the fate of many a bill over the years.

While the bill was undergoing a slow strangulation in committee hearings (killing bills one of the great arts in the US political system), the FTC and Rockstar reached a settlement, the commission ruling the company had violated the FTCA (Federal Trade Commission Act (1914)) by failing to disclose the inclusion of “unused, but potentially viewable” explicit content” (that it was enabled by a third party was held to be “not relevant”).  The settlement required Rockstar “clearly and prominently disclose on product packaging and in any promotion or advertisement for electronic games, content relevant to the rating, unless that content had been disclosed sufficiently in prior submissions to the rating authority” with violations punishable by a fine of up to US$11,000.  In the spirit of the now again fashionable Calvin "silent Cal" Coolidge (1872-1933; POTUS 1923-1929) era capitalism, no fine was imposed for the “hot coffee incident”, honor presumably satisfied by the company already having booked a US$24.5 million loss from the product recall earlier mandated.

Epoch

Epoch (pronounced ep-uhk or ee-pok)

(1) A particular period of time marked by distinctive features, events etc.

(2) The beginning of a distinctive period in the history of anything.

(3) A point in time distinguished by a particular event or state of affairs; a memorable date.

(4) In geology, any of several divisions of a geologic period during which a geologic series is formed (much associated with rock formation).  An epoch (the shortest division of geologic time) is a sub-division of a period.  As a geochronologic unit, an epoch can range between hundreds of thousands to millions of years.

(5) In astronomy, an arbitrarily fixed instant of time or date, usually the beginning of a century or half century, used as a reference in giving the elements (such as coordinates of a planetary orbit) relating to a celestial body.

(6) In astronomy, the mean longitude of a planet as seen from the sun at such an instant or date.

(7) In chronology, astronomy & computing, a specific instant in time, chosen as the point of reference or zero value of a system that involves identifying instants of time.

(8) In physics, the displacement from zero at zero time of a body undergoing simple harmonic motion (the displacement of an oscillating or vibrating body at zero time).

(9) In AI (artificial intelligence), one complete presentation of the training data set to an iterative machine learning algorithm.

1605-1615: From the Medieval Latin epocha, from the Ancient Greek ἐποχή (epokhḗ) (epochē) (a check, cessation, stop, pause, fixed time, epoch of a star (ie the point at which it seems to halt after reaching the highest, and more generally the place of a star (thus the extension of use to “a historical epoch”))), from ἐπέχω (epékhō, (to hold in, check), the construct being ἐπι- (epi-) (upon) + ἔχω (ékhō) (to have, hold), from the primitive Indo-European root segh- (to hold).  The early seventeenth century adoption in English of epocha was in the sense of “point marking the start of a new period in time” and it was used by scholars and theologians of momentous events in history (the crucifixion of Christ; the Visigoths gathering at the gates of Rome etc).  Less than a decade after epocha had entered the language, the transferred meaning “a period of time” was in use and it entered the jargon of geology in 1802 although the technology then did not permit precise measurements and exploration was then embryonic (what are now understood as dinosaur fossils not so classified until 1824) so most of the early estimates of geological epochs were inaccurate.

Confusingly, “epoch” can be used either to refer to a distinct and defined historic period (ie with an agreed beginning & end) or the event associated with the beginning of that period.  The latter concept is best understood in the adjectival forms “epoch-making” and “epochful”.  Subepoch is a technical term from geology, used as a geochronologic unit comprising one or more ages, being a period of generally agreed significance within an epoch.  The companion superepoch (two or more sequential epochs references as one for illustrative or didactic purposes is non-standard.  In statistical analysis, sub_epoch, base-epoch, super_epoch & primary_epoch exist as commands in aspects of database handling and manipulation, the link being the use of “datum” as epoch’s coordinate term in cartography and engineering.  The alternative form epocha was in use between the seventeenth & nineteenth centuries.  Epoch is a noun & verb, epochful, epocjless & epochal are adjectives and epochally is an adverb; the noun plural is epochs.

The Belle Époque (appearing in texts often as La Belle Époque with capitalization not always used) was a period in European history characterized by peace, progress, cultural refinement and artistic innovation; the term was an adoption of the French La Belle Époque (literally “the beautiful era” and best understood as “the golden age”).  Historians date the start of the Belle Époque from the end of the Franco-Prussian War (1970-1871) although, “on the ground” it likely wasn’t so clear-cut because the impositions of war reparations made the first few post-war years “difficult” in France so “mid-1870s” may be a better point of origin.  The Belle Époque lasted until the blast of World War I (1914-1918) destroyed the continent’s sense of optimism and ended an era characterized by what might now be call an “end of history” feeling that held things like wars, famines and plagues were in the past and the future would be one of progress and improvement.

Art Nouveau.

An advertisement (1899) for Moët & Chandon's champagnes, designed by Czech painter & graphic artist Alphonse Mucha (1860–1939):  “White Star” champagne (left) & “Grand Crémant Imperial” (right).  The product is very much a period piece, Art Nouveau characterized by swirling shapes, stylized representations of women and intricate floral motifs.  For those with enough disposable income, La Belle Époque must have been an amusing time to live.  The “modern industrial” sense later summoned by the straight, sharp and geometric lines of Art Deco was a deliberate rejection of Art Nouveau's intricate, hand-crafted aesthetic yet in Art Deco the influence of the earlier style often is apparent.  Although by the 1920s unfashionable and in the inter-war years casually dismissed by many critics and historians, Art Nouveau's popular appeal never went away.  While there was never really a “revival”, the style's motifs remained a staple of commercial graphic art and the various “nostalgia movements” before being “cherry picked” by pop art, psychedelia and postmodernists.   

Those 40-odd years of what came to be called La Belle Époque were not without conflict or economic disruptions and it must be remembered Europe’s “golden age” was one of untroubled pleasure only for a select few, most of the population living lives of hard labor and drudgery, many on a variation of the Hobbesian (the very clever and deliciously wicked English philosopher Thomas Hobbes (1588-1679)) path: “nasty, crowded, brutish and short”.  La Belle Époque is a selective construct of the era’s intellectual and aesthetic landmarks in art, literature and architecture, characterized by opulence, eclecticism and an undeniable dynamism from which emerged movements such as Futurism, Cubism and Art Nouveau.  Viewed from our troubled times, the Belle Époque exists in a warm nostalgic glow and it’s telling the term first gained popularity in France during the 1930s, the decade of the Great Depression.  Even then, La Belle Époque was still in living memory but because it became mythologised as a “golden age”, it was as myth it passed into history.

Lindsay Lohan entering her fifth decade.  Her five eras thus far may loosely be labelled: (1) child star, (2) troubled Hollywood starlet, (3) nemesis, (4) reinvention and (5) redemption.

Signed to the Ford agency, Lindsay Lohan secured her first modelling gig aged three but what’s understood as the “Lindsay Lohan era” ran for the decade after the release of Mean Girls (2004).  It was characterized by her low-speed car crashes, court appearances and becoming a staple of the tabloid press and lower reaches of the glossy magazine industry, a reasonable contribution to GDP (gross domestic product), providing predictable cash flow for paparazzi on both sides of the Atlantic.  Improbable as it once seemed, she proved a survivor in the churn of the industry's destructive “child star” machine and on 2 July, 2026 celebrated her 40th birthday.  That happened during the 23rd FIFA (Fédération Internationale de Football Association (the International Federation of Association Football which, for historic reasons, recognizes more countries than the UN (United Nations)) World Cup and, on the day, playing at the Bay Area Stadium in Santa Clara, San Francisco, USA beat Bosnia-Herzegovina 2-0 so that was a good birthday present.  

Geologyin's illustration of the concept of geological epochs.

In scientific usage there is precision, the ICS (International Commission on Stratigraphy) codifying a strict hierarchy on the discipline of geology, the structure being Eon → Era → Period → Epoch → Age.  However, in ordinary English discourse (and even in the work of professional scholars and historians) there is no fixed hierarchy in that an age may be longer than an era and an era may be longer than an epoch; unless following established conventions, writers can opt for whichever word best conveys the intended nuance, a choice that can be influenced by the search for rhetorical effect or the rhythm of the narrative.  So, in the way of English, there are no “rules” but, as a general principle, (1) Age = “known for...”, (2) Era = “lasting period of...” and (3) Epoch = “a period with a turning point that defined its nature.”  The overlaps in use don’t usually cause confusion but among the fastidious there are acknowledged nuances and accepted conventions of use:

(1) An epoch is a distinct period marked by particular characteristics or events, thus the use in geology where defining changes or sets of conditions can be established by scientific techniques such as chemical analysis or radiocarbon dating.  In non-scientific use, because of the etymological lineage, an epoch typically begins with some sort of event thought a turning point or watershed and this can be an organic development with no exact fixed date (the Industrial Revolution) or something decidedly exact (the epoch of the computer operating system Unix is defined as 00:00:00 UTC, 1 January 1970 although this was not first set precisely then).

(2) An age is a period with a specific, dominant association.  That might be a technology (bronze age; oil age; jet age etc), a characteristic (age of empires; age of European colonialism etc) or an individual (Napoleonic age; Elizabethan Age etc).  Unlike the epochs of geologists and astronomers, “ages” can run in parallel or overlap.  While some are sequential such as the “Three Age System” (Stone Age; Bronze Age; Iron Age) tracking the evolution of humanity's tools and metalworking capabilities between prehistory and Antiquity, others can co-exist such as the Age of Sail & Age of Enlightenment.  Because of the nature of the word and historic pattern of use, of the three, “age” is the most flexible and adaptable because it’s merely associative, not exclusive and often with no precise chronology.

(3) An era is a period (by human standards usually but not necessarily long) with origins at a certain point (usually an event) and characterized by an enduring pattern; eras tend to be major historical phases or systems (the Nazi era; the analogue era etc).  Generally “era” is used to denote something coherent (though it need not be long); a stretch of history with a recognizable character, a beginning and an end.  That can reference the life of an individual (Queen Victoria lent her name to the “Victorian era” 1837-1901), several individuals (there were four Kings of England named George whose collective reign defined the “Georgian era” 1714-1830) or a specific closed-time set (the “inter war era”: 1918-1939).

Eras tour merchandise.  Canvas tapestry featuring photographs from Taylor Swift’s The Eras Tour, cotton canvas, 800 mm (31½ inches) x 1220 mm (48 inches).

Taylor Swift’s “Eras” project tends to be thought of as a concert tour but it’s better imagined as pop culture’s greatest ever exercise in vertical integration, a merging of music (audio streaming, packaged (in multiples in the case of the vinyl releases) & live performance), video content, merchandise ranging from framed posters, a “limited edition” book, a film with concert footage, outfits emulating those worn on stage, jewellery, hoodies, pillows, stainless steel tumblers and more.  Although there has in recent years been a bit of mission creep, the idea of a canvas tapestry as a piece of tour merchandise in the pop music business would, until recently, likely have occurred to few.  Commerce has moved on from a half-century earlier when, at a Led Zeppelin concert, one might be able to buy a Tee-shirt (in S, M, L & XL), maybe with a choice of black or white (black quickly selling out).

Ms Swift is good with words and for the “Eras” project may have pondered using “Ages” or “Epochs”.  Given the accepted conventions (Age = “known for...”, Era = “lasting period of...” and Epoch = “a period with a turning point that defined its nature.”) and the concept of the “Eras” project, a convincing case could have been made for “Ages” because each subset was thematically distinct while the use of “Epochs” would have worked because the word is understood as a “period of time with a beginning and end” but linking each with a single “triggering event” might have descended to abstractions so “Eras” seems the best choice.  Certainly it’s unlikely she long considered using “Periods”; although etymologically defensible, it would have been decarded on much the same basis as that of the publishers of the magazine Australian Women’s Weekly who, upon in 1983 switching to issuing monthly editions, opted not to change the title to “Women’s Monthly”.

There is of course a vagueness associated with the definitions because not all “eras” and “ages” have as convenient bookends the end of one war and the start of another; that’s why context can matter.  In speaking of the time after World War II (1939-1945), “post-war era” is a common term but the meaning can vary depending on what’s being discussed.  It’d be absurd to speak of 2026 as being in the “post-war” era (although in a sense that’s true) so meaning must be gleaned from context.  The two decade period 1918-1939 came to be called both the “inter-war” and “pre-war” era (although many tend to restrict the latter to a start-point in the mid-1930s) and in much historiography there's sometimes the suggestion the “post-war” era can usefully be said to have ended some 20 years hence; that’s about 1965 so conveniently (1) in the new era of the High Cold War, (2) about the length of a then typical “generation” and (3) in the 1960s, a very different era.  So it can be inexact and some with a focus on political economy fix the end date on exactly 17 October 1973, the day OAPEC (Organization of Arab Petroleum Exporting Countries) proclaimed an oil embargo targeting the US and other states providing military aid to Israel during the 1973 Yom Kippur War.  At that point, the West’s long post-war boom, although already stuttering, ended.  In a similar vein, although also very much a Western-centric view, some historians have argued the nineteenth century is best imagined as a construct running from the close of the Congress of Vienna (1814-1815) to the outbreak of World War I (1914-1918).  There’s much support for that although there are different views about the conceptual view of the twentieth century. While 1914 seems a logical starting-point, candidates for the end date include 1989 (fall of the Berlin Wall (1961-1989)), 1991 (dissolution of the Soviet Union (1922-1911)) and the 9/11 terrorist strikes in 2001.

Taylor Swift Style: Fashion through the eras.

Between March 2023 and December 2024, Taylor Swift’s “Eras” tour took in 149 shows in 51 cities over five continents; each performance ran for a remarkable 3½ hours and there was a mid-tour revision of the song set to interpolate material The Tortured Poets Department (2024), her eleventh studio album.  The “Eras” title was an allusion to the show’s format, a retrospective in which each of her albums was designated as a “musical era”, the many outfits worn tied to those themes and just as each song and each performance was a product, so could be each outfit, some available on-line for purchase by devoted Swifties.  So, as set piece events go, Ms Swift set a high bar and, on revenues in excess of US$2 billion, profits were high and continue to grow.

Even when there are precise start and end dates, things can at the margin become blurred.  Pedants enjoy pointing out the 1960s began on 1 January 1961 so an expression like “the 1960s” ends on 31 December 1969 but the decade in which most of those years existed actually includes 1970, a quirk which extends also to centuries and millennia, something ultimately a product of there being no year zero in the calendar now defining BCE (before Common Era) and CE (Common Era) (the pair the secular version of BC (Before Christ) and AD (from the Latin Anno Domini (in the year of the Lord)), all based on the (nominal) birth date of Jesus Christ.  “Ages” and “eras” can at once be “exact” and “indicative”.  Many of the civilizations of antiquity all had their so-called “golden ages” and these tended to be associated with particular dynasties or reigns.  The examples are many and are cross-cultural, including the Gupta Empire in India (mid-third to mid-sixth century AD) founded by Mahārāja Śrī-Gupta, the Tang dynasty (626-684) & the reign of Tae-tsong (618-626) in China and, in Egypt, the reigns of Sethos I and Ram'eses II (1336-1224 BC).  In the West, the use of “golden ages” is legion including in Russia during the rule of Czar Peter the Great (1672-1725) (memorable because the Russian people have not enjoyed many “golden ages”) and, of course, in England, the “Elizabethan age”, referencing the reign of Elizabeth I (1533–1603; Queen of England & Ireland 1558-1603).  However, at the granular level, the idea of the term “Elizabethan age” denoting a “golden age” in literature was contested by the English writer, literary scholar and Anglican lay theologian C. S. Lewis (1898–1963) who, in his Introduction to English Literature in the Sixteenth Century (1654), distinguished the “estimable” literature of the later Elizabethan period from what he called that of the earlier “drab age”.  Lewis found drabness in the poetry and prose of the later medieval period up to the early Renaissance, distinguishing it from the “golden era style” between circa 1580-1603.  Lewis was an uncompromising critic but while most in the profession may well agree much that was written in the fifteenth century and early Tudor period was “drab”, among those published in the period were Sir Thomas Wyatt (1503-1542) and John Skelton (circa 1460-1529); their writing was not beyond criticism but the works were hardly drab.

Simulacrum describes an image that while not purely realistic, maintains enough of a likeness for the subject to be recognizable.  In some jurisdictions it can be deemed “deceptive and misleading” if a product is represented in manner judged to be a “deliberate misrepresentation” intended to induce a purchase.  Legal recourse is available but is practical only if enough money is involved (such as real estate); although in theory someone purchasing a McDonalds Big Mac after being tempted by the image in the advertising might have grounds for an action, a claim of under $US10 would not impress a judge and even a class action would, on several grounds, be thrown out.  Presumably a disgruntled consumer could lodge a claim for the “pain & suffering” caused by one's Big Mac not looking as attractive as the one in the advertising but that'd likely anger the judge still more.  The classic simulacrums were the stylish images rendered in the 1960s by Art Fitzpatrick (1919–2015) & Van Kaufman (1918-1995) for GM’s (General Motors) PMD (Pontiac Motor Division) and those of Ms Swift in the Eras Tour outfits are in the same “mannerist but not quite surrealist” tradition.  Although obviously “unrealistic”, these depictions are not “deceptive and misleading” because they’re so obviously simulacral and exist only as devices, the extent of the licence taken illustrated by them appearing next to a flesh & blood Ms Swift in the same outfit.  They are “impossible” rather than “idealized”.

Super simulacrum: The Colossus of Rhodes (circa 1560), hand-colored by Dutch portrait and religious painter Maarten van Heemskerck (1498–1574) on an engraving by Dutch publisher & designer Philip Galle (1537–1612).

The Colossus of Rhodes was one of the Seven Wonders of the Ancient World and although it stood for barely half a century before being felled by an earthquake, it's ruins lying for almost a millennium as a kind of tourist attraction before the metal was carted of as scrap to be melted-down an re-cycled.  The notion the statue's legs straddled the entrance to Rhodes Harbor with tall-masted ships passing between them was wholly fanciful; even with modern materials and techniques, such a construction would be impossible.  The engineers and architects of the sixteenth century would of course have known it couldn't be done but such was the allure of the era of Classical Antiquity that brilliant myths seduced the public imagination better than tiresome facts.

Other “era-related” terminology also often used interchangeably relates to that long span of history between the fall of the Western Roman Empire (476 AD) and the dawn of the Renaissance in the late fourteenth century: (1) Middle Ages, (2) Dark Ages and (3) Medieval.  “Middle Ages” is the most obviously descriptive because it refers to the period between the dying gasps of Classical Antiquity and the cultural & artistic revival of the Renaissance while Medieval simply means “relating to the Middle Ages” (although by virtue of association and use, it came to be used also as a slur).  As general principle, historians tend to divide the Middle Ages into (1) Early (476-circa 1000), (2) High (circa 1000-circa 1300) and (3) Late (circa 1300-circa 1500).  “Dark Ages” reflected the prejudices of fifteenth century writers who regarded the earlier Middle Ages (476-circa 1000) as a period of stagnation, lack of progress and “intellectual darkness”, a stark contrast to the idealized vision of Classical Antiquity they constructed from what evidence there was, “filling in the gaps” with imaginations as famously vivid as any of the Medieval scribes and artists responsible for some fabulous beasts.  The Seven Wonders of of the Ancient World” they found especially compelling, some of their speculative depictions of the Colossus of Rhodes and the Walls and Hanging Gardens of Babylon such examples of architectural gigantism even Albert Speer (1905–1981; Nazi court architect 1934-1942; Nazi minister of armaments and war production 1942-1945) might have been embarrassed.  Maybe they looked in awe at the scale of Great Pyramid of Giza and assumed all the ancients operated in “think big” mode.

Tony Abbott (b 1957; Prime Minister of Australia 2013-2015) agitprop.

Mr Abbott's combination of relentless negativity and repetition of 3WSs (three word slogans) contributed to his resounding victory in the 2013 general election although, in office, the results were mixed and it ended badly.  Recently revived as the Liberal Party's federal president (the institution's third “Lazerus with a triple bypass” after Sir Robert Menzies (1894–1978; Prime Minister of Australia 1939-1941 & 1949-1966) and John Howard (b 1939; Prime Minister of Australia 1996-2007)), Mr Abbott unquestionably was one of history's most effective leaders of the opposition but as Roy Jenkins (1920–2003) remarked of Lord Randolph Churchill (1849–1895):  “He was essentially a opposition politician and behaved as such even when in government”.  Of such matters, Jenkins was a fair judge.  Although medieval may literally mean “relating to the Middle Ages” and can be used as a neutral adjective (medieval architecture, medieval manuscripts etc), it is also used as a term of derision: “Mr Abbott’s views on certain topics seem distinctly medieval although, to be fair, the thirteenth century probably never produced a finer mind”.  Used in that way, it implies “outdated, harsh or unenlightened”, a throwback to the stereotypes of the Dark Ages but more recent scholarship has cast doubt on whether the “Dark Ages” was a time as culturally sterile and technologically stagnant and was for centuries an orthodoxy among historians.  A view now more popular is the earlier conceptions of the period were formed because of the relative scarcity of written records and although it’s now clear there was progress in agriculture, law, architecture, theology, literature, engineering and state formation, it is true that compared with what came before and what followed, progress often was fitful.  Of note also is there were in the Renaissance and beyond not a few who didn’t count “advances in theology” as progress worth mentioning.
