Pre-900: From the Middle English noun shadwe, shadu, shadue, shadowe shadow, from the Old English sċeaduwe, sċeadwe & sceadu, the oblique case forms of sċeadu (shadow, shade; darkness; protection).  The Middle English verbs were shadwen, shadwe, shadu & shadue (to shade, provide shade, cast a shadow, protect), from the Old English sceadwian (to cover with shadow, protect) (all derivative of the nouns), from the Proto-West Germanic skadu, from the Proto-Germanic skadwaz (shade, shadow), from the primitive Indo-European skeh & ḱeh- (darkness).  Contemporary forms included the Old Saxon skadowan & skadoian and the Gothic (ufar)skadwjan (to (over)shadow).  Similar forms in other Germanic languages included the Old Saxon skado, the Middle Dutch schaeduwe, the Dutch schaduw, the Old High German scato, the German schatten and the Gothic skadus (shadow, shade).  Shadow is a noun, verb & adjective, shadower is a noun, shadowdy, shadowless & shadow-like are adjectives; the noun plural is shadows.

The shadow-box was a protective display case, usually in the form of interlocking squares and wall-mounted was first advertised in 1892.  The term shadow-figure was a synonym of silhouette, dating from 1851.  Eye-shadow was a term invented for the commercial products which came onto the market in 1918, providing a convenient packaged product to achieve the look women (and apparently not a few men) had been creating for thousands of years.  Shadow-boxing was first noted in 1906, an update of the earlier (1768) shadow-fight.  The verb foreshadow (indicate beforehand was a figurative form, the idea apparently of a shadow thrown before an advancing material object as an image of something suggestive of what is to come.  It’s familiar also in the forms foreshadowed & foreshadowing and was used as a noun since at least 1831.  Although the meanings were different, in Old English there was forescywa (shadow) & forescywung (overshadowing).  The adjective shadowy was ultimately from late fourteenth century shadwi & shadewy (full of shadows, shaded (and also “transitory, fleeting, unreal (resembling a shadow)”).  From very late in the eighteenth century it conveyed the sense of “faintly perceptible”.  In The Old English there was sceadwig (shady) and the modern alternative is shadowiness but unfortunately, the marvelously tempting shadowous never caught on.  The noun shadowland came from a work of fiction in 1821 and meant “an abode of ghosts and spirits”, adopted from the early 1920s to mean an indeterminate or unhappy place”.  The noun shadowless was from the 1630s and meant literally “no shadow” the implication being of things ungodly or supernatural.

In idiomatic use shadow often appears.  To be a shadow of one's self is to have suffered some trauma meaning one is a lesser person than before.  One afraid of one’s own shadow is one of a skittish, nervous disposition.  If something is beyond a shadow of a doubt it is something certain.  The old expression sanctuary in the shadow of the church was not exactly literal: to seek sanctuary from the agents of the state by entering a church meant one had to pass through the door.  It referred to the noting that church soil in England was under the authority of the pope in Rome, not the King.  To throw (or cast) a shadow over someone is to seek to deny them visibility; to keep them out of the limelight.

1969 Rolls-Royce Silver Shadow.

In continuous production until 1980, the Rolls-Royce Silver Shadow was introduced in 1965 and with over 30,000 (including the less common but substantially identical Bentley T2 variant) built, it remains the Rolls-Royce made in the greatest volume.  Although there was little about the model which was cutting-edge, it was the first truly modern Rolls-Royce, forsaking the separate chassis, drum brakes and styling which used updated motifs from the 1930s; it was the template with which the company would underpin its products for the rest of century.  Although the huge Phantom V & VI limousines would continue to use a separate chassis until 1990, their annual production was measured (usually at most) in the dozens and it was the Silver Shadow and its derivatives which were the company’s bread and butter.  The adoption of unitary construction meant the end of the line for many specialist coachbuilders and some of the relics of the industry were absorbed by the factory, the Mulliner name still used by Bentley to adorn the even more expensive “special order” vehicles the 1% need to convey the message of wealth something "off the shelf" can’t manage.

However, on the Silver Shadow platform, James Young, one of the last surviving coachbuilders, did build 35 two-door saloons before the business was shuttered in 1968.  The quirk of the James Young Silver Shadows is truly they were just the standard car with the rear-doors removed and the front units lengthened and it suffered because the competition was the two-door designed by Mulliner Park Ward (MPW) which by then was a specialist division within the factory.  With greater resources and access to all the technical data, the MPW effort was more imaginative and judged universally to be more attractive, its “cow-hip” style (nobody ever suggested using the "cokebottle" appellation Chevrolet & Pontiac had a few years earlier made a trend) carried over when the car was in 1971 re-named Corniche and listed as a regular production model.  The Corniche proved the longest-lived of all the Silver-Shadow family, the convertible (even Rolls-Royce eventually gave up calling such things drophead coupés (DHC)) remaining available until 1996.

Applied with different colors in different ways, eye shadow can achieve various effects.  Lindsay Lohan demonstrates.

The archeological evidence suggests eye shadow is one of humanity’s oldest forms of make-up, worn (usually but not exclusively by women) for thousands of years, and the preparations have included oils and a variety of substances to create the desired colours including minerals & vegetable extracts although charcoal is thought to have been one of the most accessible and popular materials.  The usual rationale for applying eyes shadows is that it’s essentially the same technique as chiaroscuro, a trick used by painters, photographers & film-makers to use real & emulated light and dark to achieve the perception of depth.  Because shadows are inherent to the shape of the eye-socket, eye shadow can be use to accentuate or soften the effect and, if applied with expertise, can even alter perceptions of size and shape.  With a sympathetic choice of shade, the color of the eyes can also be used as a contrast, some taking advantage of colored contact lens to create a look impossible with their natural irises.  Done well, there's no other way to describe the combination of eye shadow and purple contact lens that "eye catching".  Eye shadow can draw attention to the eyes, most trying to make them appear larger, more vibrant, or more expressive.  Despite the name, eye shadow is a flexible product and often used to create a visual illusion on body parts such as the cheeks or décolletage.

Shadow Volumes

Example of shadow mapping with Python summarized by FinFET.

In computer graphics, shadow volume is a technique used to render realistic shadows in three-dimensional (3D) renderings which is employed primarily when dynamic, interactive real-time movement is needed, most obviously in gaming.  Essentially, generating shadow volumes involves determining those addresses in a scene which need to appear as shadows, then rendering them accordingly.  The technique relies on the concept of extruding the boundaries of shadow-casting objects to create a "shadow volume" that represents the space occluded by the object.  In static scenes this was always easy (if once time-consuming) to achieve but when objects nwere moving, until recent decades, the graphics capabilities of computers were insufficient for them to be rendered in anything close to being real-time.  The process essentially is:

(1) Determining shadow casters: The rendering engine identifies objects in the scene capable of casting shadows by calculating the object's position and shape and its relationship to the positions of light sources.

(2) Creating shadow volumes: For each shadow-casting object, the engine constructs a shadow volume based on extending the object's silhouette (defined by the address of the boundaries) in the direction opposite to the light source.  The silhouette is determined by the math of the boundaries viewed from the perspective of the relevant light sources.

(3) Intersecting shadow volumes: The shadow volumes are then intersected with other objects in the scene to determine which parts of those need to be inside or outside the shadow.

(4) Rendering shadows: The shadow volumes are assembled, rendered with darker hues or modified shading techniques to simulate the shadowed regions.

Shadow volumes can be implemented using more than one different algorithm, the most commonly used the z-pass and the stencil buffer.  All techniques are computationally intensive and have been made possible by the advances in the sheer power and complexity of modern graphical processing units (GPUs).

The Microsoft Volume Shadow Copy Service (VSS)

The handy Nirsoft Utilities includes a Shadow Copy viewer.

Microsoft introduced Volume Shadow Copy Service (VSS) with Windows XP (2001).  It worked in conjunction with the High Performance File System (HPFS) and allowed for the creation of point-in-time snapshots or copies of files and volumes on a disk.  What was in 2001 still something of a novelty for most users was the snapshots were taken while the files were in use, enabling access to previous versions or the restoration of files to a specific state, even if they have been been modified or deleted.  The process sequence was:

(1) Snapshot creation: VSS creates a snapshot of a volume or individual files on a disk.  This snapshot represents a "shadow" of the data at a moment in in time.

(2) Copy-on-write mechanism: As files are modified or deleted on the original volume, the VSS utilizes a copy-on-write mechanism.  It stores the original data in the snapshot, allowing users to access the unchanged version while the new changes are written to the live volume.  The lag induced by this can be measured with the appropriate but except with the largest files or on a busy network, it’s not usually something which affects the user.

(3) Shadow copy storage: The shadow copies are stored in a separate location on the disk, typically in a hidden system folder. The storage space occupied by is system-managed by the system, older copies automatically deleted as space is demanded for newer versions.

(4) User accessibility: Users can access the shadow copies through various means, most obviously the "Previous Versions" tab in file properties or the "Previous Versions" feature in Windows Explorer. These interfaces allow users to browse and restore files from a previous point in time.

Shadow copies provided one of the first forms of dynamic file backups for most users and were a convenient form of data recovery without the need of third-party software or external devices.  At scale, similar processes are used by software by companies such as StorageCraft’s ShadowProtect which system administrators can configure in a way that the potential data-losses can be minimized to windows as short as a few minutes.  Combined with off-site backups on large capacity media, it’s still a pest practice approach to data preservation.

Lindsay Lohan's strangely neglected film Among the Shadows (Momentum Pictures, 2019) was also released in some markets as The Shadow Within and it's not known what prompted the change (although there was a film in 2007 called The Shadow Within).  Given the two titles under which the film was distributed have quite different meanings, presumably either the title is incidental to the content or equally applicable.  A dark and gloomy piece about murderous werewolves and EU politicians (two quite frightening species), perhaps both work well and no reviewer appears to have commented on the matter and given the tone of the reviews, it seems unlikely there'll be a sequel to resolve things.

Cockade

Cockade (pronounced ko-keyd)

(1) A rosette, knot of ribbon, etc, worn usually on the hat as part of a uniform, as a badge of office, or the like.

(2) A feather or ribbon worn on military headwear, the colors of which served as unit identification.

(3) In (mostly military) aviation, an emblem of concentric circles of different colours, identifying the country to which an aircraft belongs (often called a roundel).

1650–1660: As cockade, an eighteenth century adaption of the earlier cockard, from the French cocarde (a knot of ribbons), from the Middle French cocquard (boastful, silly, cocky), the construct being coc (rooster, cock) + -arde (-ard).  The French suffix –arde was the female equivalent of –ard and was from the Middle French, from the Old French –ard & -art, from the Frankish -hard (hardy, bold), from the Proto-Germanic harduz (hard), from the primitive Indo-European kert- & kret- (strong).  It was used to form pejoratives, diminutives, and nouns representing or belonging to a particular class or sort.  The French cockade gained its name from the resemblance of the devices to a cock's crest, being from cocarde (feminine of cocard (arrogant, strutting) and thus cocquard (boastful, silly, cocky) which was an allusion to the behavior of the strutting rooster which appears so arrogantly boastful).  Cockade is a noun and cockaded is an adjective; the noun plural is cockades.

A gothic flavored Lindsay Lohan in Chanel with white rosette, MTV Studios, New York City, December 2005.

The companion (an now more widely used) term rosette describes a rose-shaped thing which may be an ornament, a fitting or any number of circular things, the best known of which are those with many small parts in concentric circles, especially when formed from a bunch or knot of ribbons and worn as a decoration or award.  Dating from 1790 from the French rosette (a diminutive of rose), rosette has a wider range of application than cockade and in the abstract is a generalized term referring to any number of stylized items which to one degree of another, are vaguely rose-like.  Rose was from the Middle English rose & roose, from the Old English rōse, from the Latin rosa, of uncertain origin but it may via Oscan be from the Ancient Greek ῥόδον (rhódon) (rose), from the Old Persian wṛda- (flower) and Middle Iranian borrowings including the Old Armenian վարդ (vard) (rose), the Aramaic וַרְדָּא‎ (wardā) & ܘܪܕܐ‎ (wardā), the Arabic وَرْدَة‎ (warda) and the Hebrew וֶרֶד‎ (wéreḏ)), from the primitive Indo-European wr̥dos (sweetbriar).  The –ette suffix was from the Middle English -ette, a borrowing from the Old French -ette, from the Latin -itta, the feminine form of -ittus.  It was used to form nouns meaning a smaller form of something.

Cockades fulfilled the function of maintaining the shape of a hat and were usually formed as a bow or knot of ribbons.  Inherently ornamental whetever their intended functional purpose, cockades quickly came to be used to signify the wearer’s identification with a political party, a particular military unit, or a household (in the form of livery).  They could be a matter of life or death during the French Revolution (1789) because the revolutionaries wore blue, white, and red cockades adopted from the colours of the royal family and the city of Paris.  The royalist forces and other reactionaries adopted white, orange, or black and yellow cockades (depending upon the nationality of the army in which they were serving), the French émigrés apparently preferring white.  The military often retained the colors but the use of cockades as such ceased for all but a handful of ceremonial uniforms when first armies and later navies ceased wearing cocked hats.  They’re still seen as a fashion item and a few of the surviving royal households have maintained their use in the leather cockades on the headgear of liveried coachmen and chauffeurs.

Although it seemed an early call, Nylon, after surveying the frocks at the 2023 Golden Globes, declared that rosettes were not only back but trending, noting the catwalks at the European spring shows were lush with floral themes.  Their conclusion: when roses bloom, rosettes surely follow.  If so, the fashion cycle is following the usual routine although the rapidity of cyclical churn does seem to have accelerated; whereas for most of the period since the seventeenth century when mass-produced rosettes first became a thing, the gaps between their splashes of popularity could be measured in decades, now they seem to be showing up every second generation.  Widely used in the 1980s (often as a bolt-on to the dreaded scrunchie), they re-appeared early in the new millennium and now Nylon says they’re back.

Still used around the world as (mostly amateur) awards in sporting and other competitions, rosettes displaying party affiliations were once a feature of elections in much of the English-speaking world but never really caught on in the US where badges, buttons, banner and latterly, stickers were preferred.  In the modern age, their use has faded just about everywhere except in the UK where they remain an essential part of atmospherics of campaigning and New Zealand where they’re still sometimes seen.  In the UK, they’re now more standardized than they were during much of the twentieth century when the sizes could vary greatly and there was no such thing as an official party color, some candidates even switching colors between polls, either at whim or in the quest for electoral advantage.  The advent of color television changed that and the party leaderships insisted on a consistent theme.  The electoral authorities also impose restrictions on the text which can be displayed and limit the size of rosettes which can be worn at polling places.  The convention of use in the UK evolved into:

Red: Labour
Blue: Conservative
Amber: Liberal Democrats
Green: Green Party
Yellow: Scottish National Party
Red, white and blue: Democratic Unionist Party
Green and orange: Plaid Cymru
Light blue: Reform UK
Purple: UK Independence Party

Nylon could be onto something.  The sequined lace column gown by Valentino Lindsay Lohan wore for the Falling for Christmas premiere (New York City, November 2022) was embroidered with a floral motif.  The reaction was generally positive.

Deadman

Deadman (pronounced ded-man or ded-muhn)

(1) In architecture and civil engineering a heavy plate, log, wall, or block buried in the ground that acts as an anchor for a retaining wall, sheet pile etc, usually by a tie connecting the two.

(2) A crutch-like prop, used temporarily to support a pole or mast during the erection process.

(3) In nautical use, an object fixed on shore temporarily to hold a mooring line.

(4) In nautical use, a rope for hauling the boom of a derrick inboard after discharge of a load of cargo.

(5) In mountaineering a metal plate with a wire loop attached for thrusting into firm snow to serve as a belay point, a smaller version being known as a deadboy.

(6) In slang, a bottle of alcoholic drink that has been consumed (ie is empty).

(7) In the operation of potentially dangerous machinery, a control or switch on a powered machine or vehicle that disengages a blade or clutch, applies the brake, shuts off the engine etc, when the driver or operator ceases to press a pedal, squeeze a throttle, etc; known also as the deadman throttle or the deadman control.  The hyphenated form dead-man is often used, both as noun and adjective.  Deadman is a noun and the noun plural is deadmans which seems ugly and a resulting formation such as "seven deadmans" is surely clumsy but most authoritative reference sources insist only "deadmans" will do.  Deadmen or dead-men is tolerated (by some liberal types) on the same basis as computer "mice" although "mouses" doesn't jar in the way "deadmans" seems to.

Circa 1895: A compound word, the construct being dead + man.  Dead was from the Middle English ded & deed, from Old English dēad, from the Proto-West Germanic daud, from daudaz.  The Old English dēad (a dead person; the dead collectively, those who have died) was the noun use of the adjective dead, the adverb (in a dead or dull manner, as if dead," also "entirely") attested from the late fourteenth century, again derived from the adjective.  The Proto-Germanic daudaz was the source also of the Old Saxon dod, the Danish død, the Swedish död, the Old Frisian dad, the Middle Dutch doot, the Dutch dood, the Old High German tot, the German tot, the Old Norse dauðr & the Gothic dauþs.  It's speculated the ultimate root was the primitive Indo-European dheu (to die).Man was from the Middle English man, from the Old English mann (human being, person, man), from the Proto-West Germanic mann, from the Proto-Germanic mann (human being, man), probably from the primitive Indo-European mon- (man) (men having the meaning “mind”); a doublet of manu.  The specific sense of “adult male of the human race” (distinguished from a woman or boy) was known in the Old English by circa 1000.   Old English used wer and wif to distinguish the sexes, but wer began to disappear late in the thirteenth century, replaced by mann and increasingly man.  Man also was in Old English as an indefinite pronoun (one, people, they) and used generically for "the human race, mankind" by circa 1200.  It was cognate with the West Frisian man, the Dutch man, the German Mann (man), the Norwegian mann (man), the Old Swedish maþer (man), the Swedish man, the Russian муж (muž) (husband, male person), the Avestan manš, the Sanskrit मनु (manu) (human being), the Urdu مانس‎ and Hindi मानस (mānas).   Although often thought a modern adoption, use as a word of familiar address, originally often implying impatience is attested as early as circa 1400, hence probably its use as an interjection of surprise or emphasis since Middle English.  It became especially popular from the early twentieth century.

Calameo Dual-purpose MIL-SIM-FX mechanical dead-man and detonator switch (part-number MIL-12G-DMS).

The source of the name is the idea that if something is likely to in some way be dangerous if uncontrolled, operation is possible only if some device is maintained in a state which is possible only by a person not dead or in some debilitated condition.  The classic example is the train driver; if the driver does not maintain the switch in the closed position, the train slows to a halt.  Some manufactures describe the whole assembly as a "deadman's brake" and the part which is subject to human pressure as "deadman's switch" (or deadman's handle".  The phrase "dead man's fingers" is unrelated and is used variously in zoology, botany and in cooking and "dead man's rope" is a kind of seaweed (a synonym of sea-laces).  The legend of the "dead man's hand" (various combinations of aces and eights in poker) is based on the cards in the hand held by the unfortunate "Wild Bill" Hickok (1837–1876) when shot dead at the poker table.  A "dead man's arm" was a traditional English pudding, steamed and served in the cut-off sleeve of a man's shirt.  The phrase "dead man walking" began as US prison slang to refer to those on death row awaiting execution and it's since been adopted to describe figures like politicians, coaches, CEOs and the like who are thought about to be sacked.  Reflecting progress in other areas, dictionaries now list both "dead woman walking" and "dead person walking" but there scant evidence of use.

Deadman and the maintenance of MAD

The concept of nuclear deterrence depends on the idea of mutually assured destruction (MAD): that there would be certain retaliation, even if a nuclear first-strike destroyed the usual command and control structures of an adversary, that would not guarantee there wouldn’t be a nuclear counter-strike.  All front-line nuclear-weapon states employ systems to ensure a residual capacity to retaliate, even after suffering a catastrophic first strike, the best known of which are the Russian Мертвая рука (Dead Hand) and the US AN/DRC-8 (Emergency Rocket Communications System), both of which are often referred to as doomsday devices.  Both exist to close the strategic nuclear strike control loop and were inventions of the high Cold War, the USSR’s system later taken over by the successor Russian state.  The metaphor of a deadman is accurate to the extent of the need to keep closed a loop, the difference being the consequences.

Test launch of ground-based Russian RS-24 Yars ICBM from the Plesetsk facility in northwestern Russia, 9 December 2020.

The most extreme scenario is one in which there is left not a living soul with access to the loop.  In this case, the system switches from one designed to instigate a launch of ballistic missiles to one where some act is required to prevent the attack and is thus dubbed fail-deadly, the reverse of the fail-safe systems designed to prevent inadvertent launches.  The doomsday systems use a variety of mechanical and electronic monitoring protocols designed to (1) detect that a strike has occurred, (2) determine the extent of damage and (3) attempts to maintain or restore the usual communication channels of the military chain of command.  If the systems determine worst-case circumstances exist, a retaliatory launch of intercontinental ballistic missiles (ICBMs) will be triggered.  Neither the Kremlin nor the Pentagon tend to comment on such things but, over the years, there have been (what are assumed to be managed) leaks that the systems are usually inactive and activated only during times of crisis but the veracity of this is unknown.

Royal Navy test launch of UGM-133 Trident II nuclear submarine-launched ballistic missile (SLBM) from Vanguard class submarine HMS Vigilant, 28 October 2012.

One obvious theoretical vulnerability in the USSR’s and US systems is that at points it is electronic and therefore reliant on hardware, software and an energy source.  The UK government has an entirely analogue system which uses only pen and paper.  Known as letters of last resort, each incoming prime minister writes, in their own hand, four identical letters which are placed in a sealed envelope, given to the captain of each of the navy’s ballistic missile submarines who keeps it in his on-board safe.  The letters are only to be opened if an enemy (presumably nuclear) strike has damaged the chain of command to the extent it is no longer possible for the civilian government to instruct the military on what retaliatory action to take.  As soon as a prime-minister leaves office, the letters are, unopened, destroyed and replaced with ones from the new premier.  Those circumstances requiring a letter to be opened have never transpired and no prime-minister has ever commented publicly on what they wrote so the contents remain a genuine secret, known only to the writer and whomever they told.  So, although the only people who know the contents have never spoken, the consensus has long been the captains are likely to be given one of four options: 

(1) Retaliate.  Each of the four submarines is armed with up to sixteen 16 Trident II SLMBs (submarine-launched ballistic missiles), each missile equipped with up to twelve independently targeted warheads with a range of 7,000 miles (11,000 km).  There is always at least one at sea and the Admiralty never comments on its location although, in times of heightened political tension, additional boats may be activated.

(2) Not retaliate.

(3) The captains should use their judgment.  This, known as “the man on the ground” doctrine has a long tradition in the military although it was in some circumstances rendered redundant by advances in real-time communications.  In this case, it’s “the man under the water”.  An interesting question which touches on constitutional, international and military law, is the question of the point at which a state ceases to exist and the orders of a regime can be no longer said legally to be valid.

(4) Proceed to a place under an allied country's command or control.

Friedrich Wilhelm Nietzsche (1844-1900).

There is also a probably unexplored fifth option: a prime-minister could leave in the envelope a blank page.  This presumably would be substantively the same as option (3) but would denote a different political message to be mulled over in whatever remained of civilization.  No prime-minister has ever commented publicly on the thoughts which crossed their minds when writing these notes but perhaps some might have recalled Nietzche’s words in Beyond Good and Evil: Prelude to a Philosophy of the Future (1886): "He who fights with monsters might take care lest he thereby become a monster.  And if you gaze for long into an abyss, the abyss gazes also into you."  Although troubled when he wrote that, he wasn't yet quite mad.

Medieval

Medieval (pronounced mee-dee-ee-vuhl (U), med-ee-ee-vuhl (U), mid-ee-ee-vuhl (non-U) or mid-ee-vuhl (non-U))

(1) Of, pertaining to, characteristic of, or in the style of the Middle Ages.

(2) In informal (usually disparaging) use, extremely old-fashioned; primitive; backward; uncivilized.

1820-1830: A creation of Modern English from the New Latin medium aevum (the middle age, thus pertaining to or suggestive of the Middle Ages), the construct being medi(um) (the middle) + aev(um) (age) + -al (the Latin adjectival suffix appended to various words (often nouns) to make an adjective).  The Latin medium was from the primitive Indo-European root medhyo- (middle); aevum was from the primitive Indo-European root aiw- (vital force, life; long life, eternity), also the source of eon.  Mediaeval & mediæval are the now rare alternative spellings.

Between Rome and the Renaissance

The noun medievalism, originally a descriptor of the beliefs and practices characteristic of the Middle Ages, dates from 1846, later used to describe the academic discipline studying the epoch; the adverb medievally was first noted in 1844; the noun medievalist, first used in 1847, meant "proponent of medieval styles, one who sympathizes with the spirit and principles of the Middle Ages”, but was from 1882 a companion word to the later sense of "medievalism” and used to describe historians and others “versed in the history of the Middle Ages".

The Middle Ages (or the Medieval) is one of the three epochs in Western Civilization: (1) Antiquity, (2) the Middle Ages and (3) the Modern Age (itself not to be confused with modernism or modernity).  It’s a modern construct.  The writers and historians working during the Medieval period divided history into periods such as the "Six Ages" or the "Four Empires", and, under the influence of Christian eschatology, seem universally to have though their own time to be the last before the end of the world, all referring to their age as "modern".  The phrase "Middle Ages" appeared first in Latin in 1469 as media tempestas (middle season) and this, over centuries, spawned many variants, including medium aevum (middle age) in 1604 and media saecula (middle ages) in 1625.  The more familiar medieval (and the now rare mediaeval & mediæval) is from medium aevum, its creation reflecting the enduring European reverence for the classical world (which still exists in academic historiography’s Greek and Roman factions).  The tripartite division of Western history had been used by historians for some time and became (more or less) standard after the seventeenth century German classical scholar Christoph Cellarius (1638–1707) in 1683 published his Universal History Divided into an Ancient, Medieval, and New Period.

Be prepared: Medieval armor.

Historians date the beginning of the Middle Ages from either in 410 or 476, depending on whether they prefer the Visigoth’s sack of Rome or the final overthrow of the last Roman Emperor as the crucial turning point.  A date around 1500 is usually accepted as the end of the Middle Ages but there’s no precise end-date and the transition to the modern era was marked by immense regional differences, some parts of Europe remaining distinctly medieval well into the twentieth century.  The end was more a milieu, events such as the discovery of the "New World" (1492), the fall of Constantinople (1453) and the Protestant Reformation (1520s onward) all landmarks of the transition.

Lighting up the Dark Ages: The burning of Protestant heretics, in English historian John Foxe’s (circa 1517–1587) Actes and Monuments (1653) (often published with the title John Foxe's Book of Martyrs).

The once parallel term "Dark Ages" does cause confusion.  It adopts a traditional light-versus-darkness imagery to contrast the “light” (the learning and progress Antiquity and the Modern Age) with the “dark” (the violence, backwardness and stultification of the Middle Ages), the phrase derived from the Latin saeculum obscurum (dark age), originally applied by Italian cardinal and ecclesiastical historian Caesar Baronius (1538–1607) in his writings about an especially tumultuous period during the tenth and eleventh centuries.  A memorable phrase, it caught the popular imagination and the concept came to characterize the entire Middle Ages as a time of intellectual darkness between the fall of Rome and the Renaissance, a slur most widely applied during the eighteenth century Age of Enlightenment.  It’s now less used and English-speaking historians, following their German counterparts, generally subdivide the Middle Ages into "Early", "High", and "Late", avoiding “Dark Ages” completely, those who make any mention generally noting it can apply only to the earliest centuries and then usually in the context of the paucity of documents and other historic records rather than as a damnation of a thousand-odd years.

Christ Rescuing Peter from Drowning (1370) by Lorenzo Veneziano (known as Lorenzo the Venetian, his dates of birth and death are unknown but he was active between 1356–1372).  A number of paintings from the medieval era featured the famous New Testament story in which Christ is said to have walked on water during a mighty storm.  Lorenzo's work depicts the fishing boat in which Jesus’ disciples were traveling in across Israel’s Sea of Galilee.  The story appears in three of the four Gospels (Matthew 14:22-33; Mark 6:45-52 & John 6:16-21), each telling the tale in a subtlety different way.

Cisgender

Cisgender (pronounced sis-jen-der)

(1) Noting or relating to a person whose gender identity corresponds with that person’s biological sex assigned at birth (also as cisgendered in this context) and the prefix cis- is used variously as a modifier (ciswoman, cismale, ‎cisnormativity et al) where the practices of chemistry are followed when forming names of chemical compounds in which two atoms or groups are situated on the same side of some plane of symmetry passing through the compound.

(2) A person who is cisgender.

1994:  A compound word, modeled on the earlier transgender, the construct being cis- + gender.  Cis is from the English preposition cis (on this side of) and the earliest known gender-related use of the prefix in any language was in a 1914 German language book on sexology.  In English, the first use of the prefix in the context of gender dates from 1994.  In English, cis was an abbreviation, presumably from either cosine and sine and the number i or translingual cos, i, and sin.  Latin gained the word from the primitive Indo-European ḱe (here) and it was cognate with ce-dō, hi-c, ec-ce, the Ancient Greek ἐκεῖνος (ekeînos) the Old Irish cē (here) and the Gothic himma (to this).  Gender is from the Middle English (where it at times co-existed with gendre), from the Middle French gendre from the Latin genus (kind, sort) and is a doublet of genre, genus, and kin.  The verb developed after the noun.

The Cisgender List

The word cisgender became a technical necessity when, in the late twentieth century, gender ceased to be a binary with a meaning essentially synonymous with sex; as expressions of gender fluidity became increasingly common, cisgender emerged as the preferred term to describe what gender used to be.  With gender being re-defined from a binary to a spectrum, linguistic politics became important and the imperative was to create a category for those for whom the sex identity assigned at birth continued later in life to align with their perceived gender-identity.  If it wasn’t just another point on the spectrum, there was concern cisgender would become normative, the implication being those elsewhere on the spectrum being defined as abnormal or sub-normal.  Cisgender is distinct from but interacts both with the LGBTQQIAAOP spectrum and the pronoun wars.

Possible Cisgender Pride Flags: The practice of identity politics is the staking of a claim (or the digging of a trench depending on one's view) in the battlefield of the culture wars and one aspect of this is the flying of the "pride flag" of one's group.  There have been a few proposed but none seems yet to have emerged as the accepted version.  Displaying one might be considered a hate crime so it should be unfurled with caution.   

The spectrum evolved as quite a democratic construct, something which may have been at least partially technologically deterministic in that the proliferation of points on the spectrum was driven not by medicine or the social sciences but by interaction on social media platforms.  While the users might have felt validated or empowered (and on the social, empowerment is good) by being able to adopt or invent their own self-identities, the platforms liked it because it added another filter for their ad-targeting, very handy for delivering the product (the users) to the consumers (the advertisers).  Some social media sites now offer dozens of options but there is much overlap and many are micro-variations; there appear to be about a dozen definable categories:

Agender/Neutrois: These terms are used by people who don't identify with any gender at all — they tend to either feel they have no gender or a neutral gender. Some use surgery and/or hormones to make their bodies conform to this gender neutrality.

Androgyne/Androgynous: Androgynes have both male and female gender characteristics and identify as a separate, third gender.

Bigender: Someone who is bigender identifies as male and female at different times. Whereas an androgyne has a single gender blending male and female, a bigender switches between the two.

Cis/Cisgender: Cisgender is essentially the opposite of transgender (cis from the Latin meaning "on this side of" versus the Latin trans meaning "on the other side"). People who identify as cisgender are males or females whose gender aligns with their birth sex.

Female to Male/FTM or Male to Female/MTF: Someone who is transitioning FTM or MTF, either physically (transsexual) or in terms of gender identity; probably most closely related to the earlier transvestism, a word now unfashionable, objections to its use being associative rather than linguistic.

Gender Fluid: Like the bigender, the gender-fluid feel free to express both masculine and feminine characteristics at different times.  The category can be misleading because of the use of the term gender fluidity generally to describe these matters.

Gender Nonconforming/Variant: This is a broad category for people who don't act or behave according to the societal expectation for their sex. It includes cross-dressers and tomboys as well as the transgender; again overlaps with other categories probably exist.

Gender Questioning: This category is for people who are still trying to figure out where they fit on the axes of sex and gender.

Genderqueer: This is an umbrella term for all nonconforming gender identities. Most of the other identities in this list fall into the genderqueer category.

Intersex: This term refers to a person who was born with sexual anatomy, organs, or chromosomes that aren't entirely male or female.  Outside of medicine, intersex has largely replaced the term "hermaphrodite" for humans although it continues to be used in zoology.

Neither:  Used by those who probably could be accommodated in other categories but prefer the ambiguity, indifference or imprecision of “nothing”.

Non-binary: People who identify as non-binary disregard the idea of a male and female dichotomy, or even a male-to-female continuum with androgyny in the middle. For them, gender is not a lineal spectrum but a concept better illustrated in three or more dimensions.

Other: Probably the same as "neither" but an important thing about gender fluidity is the primacy of self-identity.

Objectum: Those attracted to inanimate (non-living) objects.

Pangender: Pangender is similar to androgyny, in that the person identifies as a third gender with some combination of both male and female aspects, but it's a little more fluid.  It can also be used as an inclusive term to signify "all genders".

Trans/Transgender: Transgender is a broad category that encompasses people who feel their gender is different than the sex they were born (gender dysphoria).  Technically, it’s probably most useful as a blanket term but the historical association of the trans-prefix make it a popular choice.  The term "assigned at birth" is now popular but misleading in that it applies some arbitrariness in the habits of the nurses ticking the boxes.  The transvestites (those (mostly men) who wear women's outerwear) are at least in some cases a subset of the transgender spectrum although the term is no longer in wide use. 

Transsexual: Transsexual refers to transgender people who outwardly identify as their experienced gender rather than their birth sex. Many, but not all, transsexuals are transitioning (or have transitioned) from male to female or female to male through hormone therapy and/or gender reassignment surgery.

Two-spirit: This began life as a US-specific term which refers to gender-variant Native Americans.  In more than 150 Native American tribes, people with "two spirits" (a 1990s term coined to replace "berdache") were part of a widely accepted, often respected, category of gender-ambiguous men and women.  Whether the term comes to be adopted by other defined ethnicities (especially indigenous tribes) or such use is proscribed as cultural appropriation, remains unclear.

Elon Musk FRS.  Mr Musk was elected a Fellow of the Royal Society in 2018.

Not all are pleased with the linguistic progress.  Twitter owner Elon Musk (b 1971) in June 2023 declared the use of “cis” or “cisgender” on Twitter were “slurs” which constituted “harassment” and transgressors were subject to suspension from the platform, adding that what constituted harassment would have to be “repeated & targeted”.  Presumably that implies the terms can still be used on twitter but not as weapons.  At this time, Twitter’s guidelines define slurs and tropes as language which “intends to degrade or reinforce negative or harmful stereotypes about a protected category”.  The notion of a “protected category” is from US law and refers to a specific group of individuals who are afforded legal protections against discrimination based on certain characteristics or attributes.  These categories typically include characteristics such as race, religion, national origin, sexual orientation, gender identity, disability, age, and other similar attributes that are protected by anti-discrimination laws in various jurisdictions.  The categories are indicative rate than absolute.  The blind and infants for example can’t claim they are being discriminated against because the state refuses to permit them to hold drivers licenses and the race protections have tended to offer the most protection to minority groups.  As Mr Musk would have anticipated, his comments were quickly responded to by those recalling his asserting after assuming control of the platform the Twitter “believes in free speech” and that earlier in 2023 he’d quietly dropped from the hateful content policy the rule protecting trans people from dead-naming (the act of referring to a transgender person by their birth name, or the name they used prior to their gender transition) and mis-gendering.
