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 40^th birthday.  That happened during the 23^rd 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.

Pro-ana

Pro-ana (pronounced pro-anna)

(1) Of or relating to the position anorexia is a legitimate lifestyle choice.

(2) The on-line community advocating this view.  The most uncompromisingly pure among the community actively deny anorexia nervosa is a clinical condition.

(3) A movement for the promotion of behaviors related to anorexia nervosa. 

(4) A member of this movement or one of the related communities.

Circa 1998-2001:  The construct is pro + ana.  Pro was from the Classical Latin prō (in favor of, on behalf of), from the Proto-Italic por-, from the primitive Indo-European pr- & pro.  Ana is a clipping of of anorexia (an(orexi)a), a phonetic diminutive of the 1957 scientific term anorexia nervosa, the construct being the Ancient Greek ἀν (an) (without) + ὄρεξις (órexis) (appetite, desire) + the Latin nervōsa (nervous).  The clipping of "anorexia" was created both as verbal shorthand and coded language (so the matters of diet and related matters could be discussed without the risk of "outsiders" understanding.  "Ana" was thus a form of personification and a "cover", the outsiders hopefully assuming a young lady named Anna was being spoken of.  Pro-ana is a noun; the noun plural is pro-anas.

Only a matter of time: Lonaniana.

Ana in this context is thus obviously unrelated to the suffix -ana (familiar in forms such as “Victoriana” (of the era of the rein of Victoria (1819–1901; Queen of the UK 1837-1901)), “Americana” (of matters specific to US culture, politics etc), Holmesiana (memorabilia or writings related to the fictional detective Sherlock Holmes created by Sir Arthur ConanDoyle (1859–1930)) etc) that became popular after being adopted in continental literature.  It was from the Latin -āna (neuter plural of –ānus (feminine -āna, neuter -ānum) and was applied to create formations meaning “of or pertaining to”.  In English the specific sense originally was “a collection of things that relate to a specific place, person etc”; the suffices -ic & -ica now fulfil a similar function.  All formations created by appending –ana are pluralia tantum (from the Latin plūrāle tantum (plural as such; plural only); the term describes a noun (either in certain or all its senses) that does not generally have a singular form.  In his A Dictionary of the English Language (1755), Samuel Johnson (1709-1784) defined the suffix thus: “Books so-called from the last syllables of their titles; as Scaligerara, Thuaniana; they are loose thoughts, or casual hints, dropped by eminent men, and collected by their friends.”  An early exemplar was Thraliana, something of a gallimaufry of diary entries, jokes, poems and anecdotes, complied between 1776-1809 by Dr Johnson's dear friend by Mrs Hester Thrale (1741-1821) although those wanting something meatier will more enjoy the two volume Addisoniana (1803), a two-volume biographical and anecdotal anthology of the writings and conversations of the English essayist politician Joseph Addison (1672-1719), compiled and edited by Sir Richard Phillips (1767–1840); it’s a fine relic of a troubled time.

Palindromic elements: A collection of material relating to pro-ana would properly be titled “Pro-anaiana”.

Dr Johnson’s notion of “loose thoughts, or casual hints, dropped by eminent men, and collected by their friends” is familiar also as “table talk”.  Table talk literally is conversation (especially if informal or gossipy) among a group seated together for a meal or other social activity.  The point about table talk is it’s held to represent an individual’s “true” thoughts in unvarnished form (ie not “sanitized” for public consumption and for that reason the table talk of the illustrious or infamous often attracts interest when assembled and published.  However, such collections rarely are true transcripts and even if not deliberately misleading in that what can appear can be a verbatim account of what was spoken and an accurate summary of views and opinion, much can be lost in the transcription.  Classic examples of the difficulties historians encounter in the absence of audio recordings are the several editions of Tischgespräche im Führerhauptquartier (Table Talks at the Führer's Headquarters), published between the 1950s and 1980s, containing what were alleged to be transcriptions of (mostly) monologues delivered by Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945) to guests at his lunches or dinners between 1941-1944.  As well as being edited at the time they were written, Albert Speer (1905–1981; Nazi court architect 1934-1942; Nazi minister of armaments and war production 1942-1945) pointed out the printed copy omits so much of the repetition, pauses and linguistic stumbles that could make meals with Hitler “stiflingly boring” for “the regulars who’d heard it all, many times before”.

Etymologists are inclined insist the correct form can be only "pro-ana" and there are traditions in English which supports this but the community itself uses ana, pro ana and proana interchangeably, the most common form the short-form ana, following the practice with anorexia nervosa which is truncated to anorexia in all but formal academic or clinical work.  Over two-odd decades, pro-ana has also spawned words such as thinspiration (often clipped to thinspo) and thinology, used to describe specialized editorial content of the calling; the much less-used term pro-mia referring to bulimia nervosa.  Pro-anas are purists who maintain high-standards; those who aspire to the anahood but in some way fail are dismissed as wannarexics.

Lindsay Lohan wearing (non-ana) red wrist-string.

The ana's standard means of social identification is a simple, beaded red bracelet, the beading of some significance because variations of red bracelets, some as simple as a wrist-string, have long been used by many cultures, usually with some sort of link to the idea of a good-luck charm.  Famously, a חוט השני (the khutt hasheni, a thin scarlet or crimson string) is sometimes worn as Jewish folk custom as a way to seek protection from those misfortunes which may be aimed at one by the עין הרע (evil eye).  It's most associated with the Kabbalah sect and Kabbalic scholars say there's nothing in ancient Jewish texts about wrist-strings of any color and the "tradition" is a recent folk practice which seems to have begun in the north-eastern United States early in the twentieth century.  Anas thus need always to check for beading before reaching out.

Notes

Although at the time it never reached the critical-mass needed to coalesce into a movement, the pro-ana concept actually pre-dates the web.  Among the bulletin boards the nerdiest connected to with 1200 or 2400 baud modems in the 1980s and early 1990s were both anorexia support boards and those which celebrated the condition but, once the indexed www (world-wide-web) was "bolted-on" to the internet the spread was rapid and, by the mid-late 1990s, pro-ana was global.

Pro-ana content tends to be (1) victim stories, (2) images & clips where ribcages & shoulder blades are often seen and clavicles much admired and (3), lists of helpful tricks and techniques.  Politically, the accepted pro-ana world view is they are not suffering from an illness; ana is a human right, an essential part of their identity and just another lifestyle choice.  As pieces of design, the sites tend to use pre-defined templates and in that are unremarkable although the preponderance of monochromic (in gray-scale) imagery is noted.  The pro-ana sites began to attract wider attention early in the twenty-first century, the irony being that much of the criticism came from the very publications many suggest contribute to eating disorders.  Off and on since then, pressure from the public and anti-ana organizations has compelled many hosts to shut down pro-ana sites although these efforts are Sisyphean, the relocations usually quick.

If followed with sustained rigor, what's in this list should result in weight-loss and the ability to maintain a lower mass.  If adhered to, there should be no need to resort to using the new generation of GLP (Glucagon-Like Peptide) receptor agonists which, while effective, are (1) expensive, (2) introduce often novel chemicals to the body and (3) don't in all cases mean weight loss will be sustained once the course of treatment stops.  The GLPs should be regarded (like the various surgical options available) as "last resorts" because D&E (diet & exercise) is the better path to follow and the pro-ana path, though demanding, is straight, narrow and well-lit.  For thinspiration, on TikTok, a place spiritually pro-ana is the SkinnyTok community.  According to some modern conventions, the expected form would be “SkinnyTok” but typically they eschew the CamelCase (partial capitalization), preferring “skinnytok” because letters have a physical character, lower case denoting “thin” and upper case “fat”). An illustrative example of content is skinnytoker Trindalyn Mackenzie skinnysplaining: “skinny isn't owned, it's rented”.  Her concept is right, the phrase encapsulating the pro-ana world view.

(1) Keep track of your calories.  Set an absolute number and NEVER exceed it while trying always, gradually, to lower the number.  Within the calorie limit, aim for a diet which is 75% leafy-green vegetables & legumes, 20% tart fruit (as the whole item but NEVER just the juice) and 5% seeds & nuts.  Added sugar should be zero because enough is in the fruit but, if absolutely necessary (feelings of weakness or cravings), one daily barley-sugar boiled sweet (preferably early in the day) is OK.  After finishing barley sugar (don't chew, just let it gradually dissolve), brush teeth  as well as good oral practice this will diminish the possibility of the appetite being stimulated.  However do NOT brush teeth within about an hour of eating or drinking (especially acidic (citrus and such) or with a sugar content) because such things soften the teeth's enamel and brushing before the surface recovers can "scrub away" the weakened enamel.  What's recommended is rinsing with water or chewing sugar-free gum.  This diet mix can at the margins be varied but must stay vegan.  Nothing should be fried and while most vegetables can be eaten raw (carrot & celery sticks the preferred pro-ana snack), there are advantages in cooking some with steaming usually the best method; steam only to the point necessary (it will vary) and at that point there should still be crunchiness.  In most cases, don't peel vegetables because some of the most valuable nutritional content lies just under the skin and one highly recommended technique is to base your selection of fruits & vegetables on skin & flesh color; eat a variety of colors.  Herbs & spices add much flavor and if you use the ones you most enjoy, they will tend to train the yearnings of your taste buds away from fat, salt & sugar.  Salt intake is essential but the daily requirement is little more than a teaspoon, much of which will be obtained from food.  If adding salt, stick to the terms in the cookbooks: sprinkle & pinch.

(2) Drink lots of water; try to aim for seven litres a day but anything over five is OK.  Being hydrated is anyway healthy and drinking water before taking food helps fill your stomach faster so you’ll eat less.  Remember to not drink a lot of water at once; instead keep hydrated by drinking little amount after every few minutes.  Always drink it as cold as possible, it forces the burning of more calories to restore body temperature.  Unless operating in extreme conditions with high fluid loss, do not go over eight litres a day; water can in extreme case be toxic and death has been reported among those who have ingested around 20 litres (less may be fatal in certain individuals, especially those with a lower body mass, hence the 5-7 litre recommendation). 

(3) Place a full-length mirror in your bedroom and evaluate yourself on daily basis. This is one of the best ways to stay motivated and remember, you’re there to be critical as well as admire.  If you can arrange multiple mirrors to provide for a 360^o view that's even better because it makes it easier to focus on problem areas (these can persist even as overall weight is falling).  Hanging a thinspiration photograph next to the mirror is recommended.

(4) Have small meals.  It’s easier for the body to burn three 100 calorie meals than one of 300 and lends your body the illusion you’re eating enough to keep the stomach full, whereas you’re eating less.  Always eat slowly and chew thoroughly, it will hasten the digestive process.  After every meal, brush teeth (after waiting an hour!); again, this is good dental hygiene but with freshly brushed teeth, you'll be less inclined to eat.  

(5) Find an ana-buddy.  The pro-ana routine can be a harsh mistress so an ana-buddy with whom you can talk about your problems and diet-related stuff can be helpful but only if they're a kindred spirit.  This works not only by keeping each other motivated but you'll also teach each other new tricks or exercise routines.  You both must be 100% committed to the system and such noble souls are rare so, if need be, replace them with someone wholly committed.  You're in a war with weight so be harsh and accept only allies who will help in the fight.

(6) With the aggressive pro-ana diet, it’s very important to take vitamin pills.  Research suggests that for most people on what is the orthodox "balanced diet", vitamin supplements are probably unnecessary (some researchers suggest they can even be counter-productive) but because pro-ana doesn't include certain food groups, a daily multi-vitamin is recommended and usually adequate so resist the temptation to take two and do so only if you become light-headed or faint with any frequency; you may need specific additional supplements.  The most publicized deficiency associated with pro-ana is iron and it may thus be necessary greatly to increase the intake of leafy greens like spinach or peas, broccoli & string beans; seeds high in iron include pumpkin, sesame, hemp and flaxseeds.  One's family physician can obtain the tests to determine specific deficiencies and these should be dealt with by adjustment to diet.  Remember though that doctors are inclined to be dictatorial and the recommended technique to deal with their negativity is just to agree with whatever they say.  Try to appear sincere and be deferential; they like that.   

(7) Avoid butter and oils.  Treat them like sugar or drugs of dependency.

(8) Resist the temptation to smoke or vape.  While it's true some short-term weight loss often is achieved by smoking cigarettes, (1) in the medium-long term weigh-gain is the typical consequence, (2) the nicotine in cigarettes is addictive making it difficult to use tobacco as a short-term or occasional "quick-fix" and (3) it's a carcinogenic product which, on average, appears to reduce life-expectancy by around a decade.  Not enough is yet known about vapes but there are many reports of adverse outcomes, presumed to be a consequence of inhaling that many chemicals.       

(9) Sleep at least eight hours a day, preferably more.  Less sleep means tiredness and hunger and you can’t eat while asleep.  Try to avoid eating in the four hours before going to bed and ideally aim for at least twelve hours of fasting prior to the first food of the day (which may happen at a time later than a traditional "breakfast").  Pro-ana endorses the 4:3 diet plan (an intermittent fasting protocol in which each seven-day cycle includes three (non-consecutive) days of fasting) and there are many recommendations covering the composition of food intake on the non-fasting days (many with an emphasis on high-protein foods).  It's difficult to be prescriptive about the specifics of intake because, by definition, food interacts with human physiology and in that there's much individual variation, thus pro-ana recommending those adopting the 4:3 regime experiment to determine the most effective mix.  Individual experiences are likely to vary.

(10) Keep setting a target weight.  Because of fluid retention and other cyclical variations, it’s probably counter-production to set daily targets and a weekly goal is better although true obsessives will monitor at least once and maybe several times a day; this is not discouraged.  To stay motivated, hang on the wall thinspiration photographs of slender models to observe while weighing-in.  Many non-ana diet sites suggest avoiding weighing-in daily and clinically they may be right it achieves little but they just don't understand the nature of obsessions.  Record the weigh-ins so you can chart progress over weeks and months; this requires nothing more demanding than the most basic open-source spreadsheet but math nerds who enjoy such things can do it with pen & paper.  Although for most purposes pencils are better than pens, ink is permanent so it's harder to cheat.  You will be tempted to cheat but you must not; pro-ana does often demand you lie to others but you must never lie to yourself.

Example of a thinspiration photo: Model Lululeika Ravn Liep (b 1998), Cover magazine, February 2015.  Although the use of this image was condemned by the thought police, a true pro-anaite should think: “She could lose a few pounds.”

(11)  Do NOT drink any alcoholic beverages; for variety only soda-water or carbonated mineral water are acceptable.  Coffee and tea are good appetite suppressants so drink only black coffee or tea and NO milk or sugar.  Avoid caffeine drinks; they’ll contain either sugar or chemicals about which there exists no reliable research on how they affect the appetite.  Avoid the inherently sweet herbal teas; they do tend to stimulate the appetite in a way black tea and coffee don't.  Black tea and coffee are also useful in training the palette away from sweetness and towards the tart.  After a while, this will start to influence your choice of fruits and vegetables; as a general principle the darker and more bitter in taste, the better.  Care must of course be taken.  In its pure form, caffeine can be fatal in tiny quantities although in the form usually enjoyed (coffee), one would need to drink dozens of cups in a day to approach toxicity.  The French philosopher Voltaire (François-Marie Arouet; 1694–1778), often at the Café de Procope in Paris, drank a reputed 40-odd cups a day, enjoying it so much he ignored the advice of his doctors to stop.  He lived to 84 but there’s no evidence the often attributed quotation: “It may be poison, but I have been drinking it for sixty-five years, and I am not dead yet” was his.  The more likely source is French author Bernard Le Bovier de Fontenelle (1657–1757) whose actual words were: “I think it must be [a slow poison], for I’ve been drinking it for eighty-five years and am not dead yet.”   Fontenelle died a month short of his hundredth birthday.  The sensible approach is to restrict yourself to one strong (ie short black and such) coffee at the start of the day and otherwise just have cups of weak (even decaffeinated) instant coffee; think of it not as a stimulant but a companion.

(12) Wearing short or revealing clothing can be very motivating and definitely such garments are helpful when looking in mirror because it will be obvious there's still work to do, something often disguised by what's worn in public.  Wear in private clothes you'd never dare to wear in public and make it a goal to be able to wear them without looking fat.    

(13) Drink the juice of a squeezed lemon in hot water first thing each morning and last thing each evening; it has the general effect of adding to the stomach acids which break up food.  Because of this acid, always brush teeth afterwards (allowing the essential 60 minute delay).

(14) If you have to eat in company (it can be unavoidable), wear baggy clothes with big pockets able to be lined with plastic bags.  Then, when no one is looking, you can dispose of food and people will think you eat normally.  It sounds a difficult thing surreptitiously to manage and to start with it will be but you’ll learn to adopt techniques like always sitting in a corner or at the end of the table and soon become an expert.  It's easier than it sounds.  However, prevention being better than cure, there are plausible excuses for NOT being able to eat (fasting prior to a blood test, having "upset tummy" etc) and that means social activities can still be enjoyed with intake restricted to water, black tea or black coffee. 

(15) Exercise every day.  Gyms are optional because you can do even better with ana-specific routines such as running up stairs or hills, both of which have an extraordinary multiplier-effect on whatever distance is achieved.  Unlike gyms, it's also free and never forget the goal is weight-loss, not abstractions like fitness or muscle tone; success is not looking fit & toned, success is looking thin & frail.  If possible, exercise in darkness to avoid sun exposure; if this is not possible (and there may be good reasons to restrict this to daylight hours) cover as much skin as possible with protective clothing and use the highest available SPF (sun protection factor) sun-block lotion, wear a wide brim hat and never forget the sunglasses.  Never use elevators and escalators; always take the stairs.  Wherever possible, replace travel by cars, trains and busses with walking or biking.  This is also good for the planet which is the only one we have.

(16) Eat ice; ice can be an alternative to a meal, it really works.  Shaved ice is best because it avoids dental damage; there are many things to consider when eating ice and curiously, sometimes it's advantageous to take more, sometimes less.  For a discussion on the mechanics of ice-eating: The eating of ice

Anorexia nervosa was included in the (1952) first edition of the American Psychiatric Association's (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM) as a psycho-physiological reaction. The DSM-II (1968) moved it to Special Symptoms–Feeding Disturbances and in 1980, a new eating disorders section was created for the DSM-III.  The most significant structural change came in 1994 when in DSM-IV the condition was afforded its own section.  The DSM-5 (2013) relaxed some of the diagnostic criteria including, for the first time, rendering it all entirely gender-neutral, a gesture to conform with practices elsewhere rather than anything suggesting clinical experience was noting a greater gender-spread in the patient count.  Announcing DSM-5, the board noted it wished to reduce the number of patients in the former EDNOS (Eating Disorder Not Otherwise Specified) category, now reclassified as the OSFED (Other Specified Feeding or Eating Disorder) group.  Thus the psychiatrists staked their claim in this low-cal demarcation dispute by capturing the wannarexics.
