Illusion

Illusion (pronounced ih-loo-zhuhn)

(1) Something that deceives by producing a false or misleading impression of reality.

(2) The state or condition of being deceived; misapprehension.

(3) An instance of being deceived.

(4) In clinical psychology, a perception, as of visual stimuli (optical illusion), that represents what is perceived in a way different from reality.

(5) A very thin, delicate tulle of silk or nylon having a cobwebbed appearance, for trimmings, veils and similar designs.

(6) The act of deceiving; deception; delusion (mostly obsolete).

1340–1350: From the Middle English, from the Latin illūsiōn(em), stem of illūsiō, (irony, mocking), the construct being illūs(us), past participle of illūdere (to mock, ridicule) + lūd (play) + tus (past participle suffix) + iōn.  The suffic -ion was From the Middle English -ioun, from the Old French -ion, from the Latin -iō (genitive -iōnis).  It was appended to a perfect passive participle to form a noun of action or process, or the result of an action or process.  It was from the Latin lūd that English ultimately gained ludicrous, illudere meaning "to mock at" (literally "to play with").  The borrowing from Latin displaced the Old English dwimmer, from the Old English ġedwimor or dwimor (illusion, delusion, sleight, magic) and, as absorbed by both Medieval English & French, meaning tended towards “act of deception” rather than “mocking or irony” which was the Classical Latin form.  The English sense is reflected in the word’s use in Church Latin which is thought the source of the meaning-shift.  In modern English use, particularly since the rise of mass-market visual entertainment, to some extent the preponderant meaning has shifted back.  Illusion & illusionist are noun, illusionary, illusional and illusioned are adjectives; the noun plural is illusions.

English offers many variations on the theme; words like fantasy, hallucination and delusion all refer to false perceptions or ideas.  An illusion is either (1) a false mental image produced by misinterpretation of stuff that actually exists or (2) a deliberate creation in some form to create an impression of stuff in a way not real.  A mirage is a distortion of reality produced by reflection of light against the sky but in general use is widely deployed as a synonym for anything illusory. A hallucination is a perception of a thing or quality that is either wholly or partially unreal.  A delusion is a persistent false belief that need not have any basis.  A chimera is something which, while unreal, has many elements of the real and thus seems more plausible.  A fantasy is either (1) a fictional creation where one is aware of its untruth or (2) a fictional creation one believes.

The Illusion Panel

The illusion panel is a visual trick used by fashion designers which to some extent mimics the appearance of bare skin.  It’s done by using a flesh-colored fabric, cut to conform to the shape of wearer and the best known products are called illusion dresses although the concept can appear on other styles of garment.  Done well, the trick works, sometimes even close-up but it’s really intended for photo opportunities.  Lindsay Lohan illustrates the idea in a few examples:

At left is a gown from the Fendi Spring/Summer 2016 collection, worn at the Asian Awards, London, April 2016.  The gown was technically a different take on the illusion panel because the skin was real: Fashion faking itself.  It’s a playful take on the idea because above the modest cut at the midriff were translucent panels which created a nice effect, especially when in motion although opinion was divided on whether the geometric pattern was too busy for the concept, some suggesting a solid color or even some bold stripes might have lent better emphasis.

The centre image is of a Julien Macdonald green and blue sequin embellished mini dress with open neckline, accented with illusion panel & black hemline, from her Fall 2013 collection, worn at Gabrielle's Gala, Old Billingsgate Market, London, May 2014.  Some comment was provoked by the choice not to retain the black belt with which it was shown on its catwalk debut and it true that did work well with the hemline trim, width and shade of both matching.  However, a panel with quite that much illusion doesn’t demand accessories and probably is more effective with neither belt nor necklace to distract.

At right, dating from January 2013 is a black Dion Lee cocktail dress with illusion panels and an off-the-shoulder silhouette, the shoes Christian Louboutin peep-toe booties.  It’s a classic example of why it’s thought illusion dresses work best if tailored in solid colors with a marked contrast between material and skin tone.

Kylie Jenner (b 1997, left) in 2017 used the idea in what was (by the standards of her clan) quite subtle but trolls quickly realized the possibilities offered by digital editing (centre).  Swedish musician Tove Lo (Ebba Tove Elsa Nilsson, b 1987, right) actually enhanced the illusion with a T-shirt which included shadow effects so the look would be consistent even in settings where ambient light was unhelpful.  Pairing the T-shirt with an oversized, double-breasted blazer was a nice touch.

As a garment, an illusion dress is not technically difficult to cut or assemble but for its effect it relies on a close congruence between the colors of panel and the skin.  Assuming such fabrics are either available or can be dyed to suit, that’s fine for bespoke creations but in the vastly bigger prêt-à-porter (ready-to-wear) market, buyers are compelled to pick whatever is the closest match, the technique of choice being to alter the skin tone for the occasion, fake tanning product the usual choice which is fine if a darker hue is needed but when lightening that’s needed, the creams used temporarily to cover tattoos are said to work well, better even than the (now often controversial and in some cases dangerous) skin-lightening preparations popular in some markets.

The illusion industry also borrows motifs.  A cage bra is built with a harness-like structure which (vaguely) resembles a cage, encapsulating the breasts using one or more straps.  Few actually use the straps predominately to enhance support and the effect tends to be purely aesthetic, some cage bras with minimal (or even absent) cup coverage and a thin band or multi-strap back.  Some things about cage bras can be illusory but the skin on show is usually real whereas when used over a skin-toned panel, the straps exist to enhance the illusion although, there’s no reason why they can’t also be structural, functioning effectively as an external bra.  Ashley Graham (left) in cage bra with the focus on flesh and Ricki-Lee Coulter (right) in a dress with illusion panel under straps illustrate the difference.

The Great Illusion (1910) by Norman Angell (1972-1967) was first published in the United Kingdom in 1909 as Europe's Optical Illusion.  Angell’s theme was that the economies, financial systems, markets and supply chains of the world’s big industrial and military powers had become so inter-twined and inter-dependent that war had become impossible.  Angell proved that not only would war be unprofitable, in any big conflict, the victor would suffer at least as much as the vanquished so no nation would be so foolish as to start one.  Quickly, The Great Illusion was translated in eleven languages and in the optimistic world of early twentieth century Europe, it became a cult, its thesis a dogma.  The aristocrat commissioned to review the British Army after its disastrous performance in the Boer War (1899-1902) were understood instantly became an adherent to the idea that “new economic factors clearly prove the insanity of aggressive wars”, delivering lectures in which he pointed out that “a twentieth century war would be on such a scale… that its inevitable consequences of commercial disaster, financial ruin and individual suffering [would be] so pregnant with restraining influences” as to render the thought of war unthinkable.

Read even now, the wealth of examples he offered and the incontrovertibility of his argument seem convincing.  Unfortunately, Wilhelm II (1859–1941; Kaiser (Emperor) of the German Empire 1888-1918), although it’s known he received a copy of the book, was more influenced by one published in 1911 by the Prussian General Friedrich von Bernhardi (1849–1930) with the unambiguous title Deutschland und der Nächste Krieg (Germany and the Next War).  Bernhardi’s text is of great interest to students of military, diplomatic and political history but the casual reader can gain the necessary understanding merely by glancing at the table of contents, the uncompromising chapter headings including The Right to Make War, The Duty to Make War and World Power or Downfall.  In case anyone might have thought he had written a work of abstract theory, another chapter was titled Germany’s Historical Mission.   Describing war as a "divine business", his central two-pronged strategy was the one which would doom both the Second Reich and the Third: Wage wars of aggression and ignore treaties.

World War I (1914-1918) was something probably worse than even Angell had prophesized and in its aftermath the phrase “the war to end all wars” was popular although some of the delegates leaving Paris after the Treaty of Versailles (1919) weren’t so sanguine, reckoning all that had been gained was a truce.  Despite the cynicism however, the 1920s were the years in which the (now mostly forgotten) successes of the League of Nations included the notion that war had been made not only unthinkable (both because of Angell’s analysis and the shock of the World War) but actually unlawful.  It was a brief, shining moment and by 1933 Angell felt compelled to add to a revised edition of The Great Illusion the new theme of the need for collective defense.  Other things happened in 1933, the implications of which would mean that too would prove an illusion itself but that year, Angell was awarded the Nobel Peace Prize.

Illusions however seem to be something to which men can’t help but be drawn and by the late twentieth century, as globalization 2.0 accelerated, another part of Angell’s conceptual framework gained a new audience.  Angell had noted the obvious: That the imperative of modern capitalism was profit, not romantic nationalism and that there was more to be gained from peaceful trade than attempts at conquest with its unpredictable outcomes.  By the 1990s, political commentator Thomas Friedman (b 1953) had reduced this to what came to be called the “Golden Arches Theory of Conflict Prevention (the idea that countries with McDonalds restaurants didn’t go to war with each other) and while that’s since been proved untrue, the point he was making was the same as Angell: That democracies run according to the rules of market capitalism don’t go to war with each other because the it’s too threatening to the hegemonic class which owns the means of production and distribution.

By the time Mr Putin (Vladimir Putin, b 1952, president or prime-minister of Russia since 1999) began his special military operation (the invasion which started the Russia-Ukraine war in 2022), it’s doubtful there were many left in Europe with illusion about the nature of man.  Unfortunately, it may be that in the Kremlin the reading of Bernhardi may not have gone beyond those first few bellicose chapters because deeper into his book, the author moved beyond the justification of “necessity” to the nuts and bolts of “method” for once one convinces one’s self one has a duty to make war, one must ensure it is waged with success.  To be successful he explained, the state must begin a war at “the most favourable moment” of its own choosing, striking “the first blow” in a manner which guarantees victory.  Mr Putin had illusions of his own, about the people of Ukraine, about the West and about the state of his own military.

In 2014, an illusion outfit attracted much comment when the Colombian women’s cycling team uniform was first seen at an event in Italy, held in honour of former Italian champion Michela Fanini (1973–1994).  Despite the appearance, it wasn’t a two-piece, the otherwise standard strip augmented by a flesh-coloured section across the lower torso and upper hips.  The photographs caused a stir and the unusual degree of international attention must have pleased the team’s sponsor, the city government of Colombia's capital, Bogota.  Innovations like this might be one way to redress the imbalance in the media coverage afforded to women's sport.

Entasis

Entasis (pronounced en-tuh-sis)

(1) In architecture, a slight convexity given to a column or tower, as to correct the optical illusion of concavity and create the perception of straight lines.

(2) In medicine and physiology, an involuntary or spasmodic muscular contraction (also called entasia (from the Greek ɛnˈteɪzɪə)).

(3) In typography & calligraphy, the thinning in the waist of a stroke, the technique used to compensate for the visual perception of a stroke with perfectly straight sides appearing slightly to bulge.

1745–55: From the Latin entasis, from the Ancient Greek ἔντασις (éntasis) (tension, straining), from εντείνω (enteínō) (to stretch or strain tight), the construct being enta, variant stem of enteínein (to stretch tight) + teínein (to stretch) + sis.  The –sis suffix was from the Ancient Greek -σις (-sis) and was attached to words in English often via Latin or French.  It was identical in meaning with the Latin –entia and the English –ing and was used (1) to form nouns of action or process (catharsis, dialysis, diagnosis, crisis etc), (2) in medicine to form nouns of condition (psoriasis, sepsis, tuberculosis, psychosis etc) and more generally (3) nouns as required (basis, oasis, thesis, stasis etc).  Entasis is a noun; the noun plural is entases.

The Entasis or Parthenon Principle

Parthenon in Athens.

In modern architecture, entasis is the application of a convex curve to a surface for aesthetic purposes.  Its best-known use is in the columns from antiquity which curve slightly as their diameter is decreased from the bottom upward.  Because no relevant documents have yet been discovered, it’s not known whether the architects in antiquity applied the technique for aesthetic effect or as an engineering technique to enhance strength.  The latter is suggested by the design principle being described by Roman architect Marcus Vitruvius Pollio (circa 75 BC–circa 20 BC) using the Greek word enteino meaning "to stretch or strain tight", suggesting some emphasis on structural strength rather than appearance.  However, until contemporary records are uncovered, their reasons for using entasis remain mysterious, hence the two-thousand odd years of conjecture.  The most celebrated construction is the Parthenon in Athens.

1964 Rolls-Royce Silver Cloud III Flying Spur; coachwork by HJ Mulliner Park Ward.

The earliest known documented view of the matter was that written by Greek mathematician and engineer Hero of Alexandria (circa 10-circa 70), is that entasis corrects the optical illusion of concavity in the columns that the human eye would create if the correction were not made.  That’s the reason Roll-Royce have always used a variation of the  technique in their upright grilles; it’s to make it appear as if built with columns of identical dimensions.

Basilica's western front of the Second Temple of Hera, a Greek temple in Paestum, Campania, Italy.

The Second Temple of Hera was built in the Doric order circa 455 BC, just north of the first.  For the visual effect of entasis to work, the convex curve has to be so slight as to be imperceptible and it's not known why the Second Temple of Hera has an entasis so pronounced it creates an obvious curvature, not an illusion of straightness.  The proportions are such that historians have speculated it must have been deliberate, presumably purely for structural strength but it's at least possible the architect was afflicted by the desire many of his modern contemporaries share: The wish to produce something "original" and "new", the reason why so many modern buildings are so unpleasing to the eye.

Lindsay Lohan in Rolls-Royce Phantom Drophead Coupé (2007-2017).  By the 1970s factory (mostly) had ceased to use the historic terms FHC (Fixed-Head coupé) and DHC (Drop-Head Coupé (DHC) although and the revival in 2007 for the Phantom Drophead Coupé proved (thus far) a nostalgic one-off.

Over the decades, the designers generally were successful in their adaptations as they were required to make the grille wider and lower but the Phantom would have benefited aesthetically if a more traditional approach had been taken with the headlamps (centre) and even hidden units (right) would have been more pleasing.  Still, twenty-first century customers seem more accommodating of stylistic innovation than earlier generations.  In 1975, when the Camargue (1975-1986) was released, the novelty of it being the first Rolls-Royce designed using exclusively metric measurements (except for the odd carry-over component) attracted little attention but there was much comment about it being the first built with anything but a perfectly vertical grille.  The Camargue's grille was slanted at a (for mid-century Rolls-Royce) rakish 7^o.

The Pantheon Temple, Rome (left) and 1985 Rolls-Royce Camargue (right).

The Pantheon's Latin inscription M·AGRIPPA·L·F·COS·TERTIVM·FECIT actually isn't all that poetic and reads like a note the draftsman might have put on the blueprint (had there then been blueprints): it translates as "Marcus Agrippa, son of Lucius, made [this building] when consul for the third time.", crediting the Roman statesman & general, Marcus Vipsanius Agrippa (circa 63 BC–12 BC) who originally commissioned the construction during his third consulship in 27 BC.  The Pantheon that stands today was rebuilt by Emperor Hadrian (Publius Aelius Hadrianus, 76–138; Roman emperor 117-138) circa 126 AD after the original structure suffered severe damage in a blaze.  Hadrian chose to retain Agrippa's inscription as a tribute (not all the emperors were narcissists).  Since AD 609, the Pantheon has been a Roman-Catholic church and is known as the Basilica Santa Maria ad Martyres (Basilica of St. Mary and the Martyrs).

Despite the popular perception, what Rolls-Royce describes as their "Pantheon grill" doesn't feature a classic entasis (slight swelling in the middle of a column to counteract the illusion of concavity), the design does incorporate a similar visual effect: there is a (very) slight curvature which in the factory's vernacular is known as the "waftline".  Although there are, understandably, many references to the grill being the "Parthenon grill" (and there is a well-reviewed Greek restaurant in Murfreesboro, Tennessee called the Parthenon Grille), the factory has never used the term and say the designed was inspired by "Rome’s imposing Pantheon temple", a structure "...purposefully built with wider middle sections so the human eye perceives each long pillar to be completely straight."  What the architects of Antiquity did was use use an optical illusion as a "corrective" to achieve perfect visual symmetry and the Rolls-Royce engineers replicated the approach, the grill's columns wider towards the edges.  The waftline is used elsewhere, notably the gentle, upswept sweep along the sill-line which Rolls-Royce says "creates a powerful, poised stance and makes the car appear to be moving when stationary...", creating the impression of "calm perfect motion and accelerating quickly without fuss".  They clearly like the word "waft" because they coined the neologism "waftability" which is said to be "the essence of the brand".

The math of entasis.

Geodesic

Geodesic (pronounced jee-uh-des-ik or jee-uh-dee-sik)

(1) In spherical geometry, a segment of a great circle.

(2) In mathematics, a course allowing the parallel-transport of vectors along a course that causes tangent vectors to remain tangent vectors throughout that course (a straight curve, a line that is straight; the shortest line between two points on a specific surface).

1821: A back-formation from geodesy (a branch of science dealing with the measurement and representation of Earth, its gravitational field and geodynamic phenomena (polar motion, Earth tides, and crustal motion) in three-dimensional, time-varying space and with great (and "down-to-earth" as it were) practical application in surveying.  The adjectives geodesical & geodetic had first appeared in 1818 & 1819 respectively, both from geodetical which had been in use since the early seventeenth century.  All the forms are derive ultimately from the Ancient Greek γεωδαισία (geodaisía) from γῆ (geo) (earth) + δαιεῖν (daiesthai) ("to divide" or "to apportion") and the use in English was most influenced by the French géodésique, dating from 1815.  In general use, the word entered general use after 1953 when it was used of the "geodesic dome" (a structure built according to geodesic principles); despite the earlier use in wartime aircraft construction, the use there was only ever "engineer's slang".    Geodesic is a noun & adjective, geodesicity is a noun, geodesical is an adjective and geodesically is an adverb; the noun plural is geodesics.    The alternative adjectival form geodetic appeared in 1834 but fell from use by mid-century.  

Four-dimensional space-time.

Geodesic describes the curve that locally minimizes the distance between two points on any mathematically defined space, such as a curved manifold; essentially the path is the one of the most minimal curvature so, in non-curved three-dimensional space, the geodesic is a straight line.  Under Albert Einstein's (1879-1955) theory of general relativity (1915), the trajectory of a body with negligible mass on which only gravitational forces are acting (ie a free falling body), defines the geodesic in curved, four-dimensional spacetime.  Dictionaries and style guides seem to prefer “space-time” but scientists (and space nerds) like “spacetime” and because it was one of them who “invented it”, it seems polite to ignore the hyphen.  The term, a calque of the German Raumzeit (the construct in English being (obviously) space + time) first appeared in a paper by German mathematician Hermann Minkowski (1864–1909), published in the Philosophical Review.  The existence of the noun plural "spacetimes" does not imply something to do with the so-called multiverse (in cosmology, a hypothetical model in which simultaneously more than one universe exists) but rather that there are different space-times created in different places at different times.

General relativity fan girl Lindsay Lohan in optical illusion dress from the Autumn-Winter collection of interior designer Matthew Williamson (b 1971), illustrating an object causing the curvature of spacetime, Gift Global Gala, Four Seasons hotel, London, November 2014.  An “optical illusion dress” is one which uses a fabric print or other device to create the effect and differs from an “illusion dress” which is made with skin-tone fabrics placed to emulate the wearer’s own flesh.

In Einstein's theory of general relativity, gravity is treated not as a force as had been the historic understanding explained in the writings of Sir Isaac Newton (1642–1727) but rather as a curvature of spacetime caused by the presence of mass and (thus) energy.  The Sun, being a massive object, causes a (relatively) significant curvature in the surrounding spacetime and the Earth, as it moves through this curved spacetime, follows a path (a geodesic) which manifests as what appears to be an “orbit” around the Sun.  It is this curvature of spacetime that is perceived as the “gravitational pull” of the Sun on the Earth, keeping it in a (relatively) stable and predictable orbit.  Einsteinian physics supplanted Newtonian physics as the structural model of the universe and nothing has since been the same. 

Hull of Vickers R.100 Airship.

Sir Barnes Wallis (1887-1979) was an English engineer, best remembered as the inventor of the bouncing bomb used by the Royal Air Force in Operation Chastise (dubbed the "Dambusters" raid) to attack the Ruhr Valley dams during World War II and the big Tallboy (6 tonnes) and Grand Slam (10 tonnes) deep-penetration "earthquake" bombs.  Wallis had been working on the Admiralty’s R.100 airship when he visited the Blackburn aircraft factory and was surprised to find the primitive wood-and-canvas methods of the Great War era still in use, a notable contrast to the elegant and lightweight aluminum structure of airships.  He was soon recruited by Vickers to apply his knowledge to the new generation of fixed-wing aircraft which would use light alloy construction for the internal structure.  His early experience wasn’t encouraging, the first prototype torpedo bomber, which used light alloy wing spars inspired by the girder structure of R.100, breaking up mid-air during a test-flight.  Returning to the drawing board, Wallis designed a revolutionary structural system; instead of using beams supporting an external aerodynamic skin, he made the structural members form the aerodynamic shape itself.

The geodesic structure in an airframe.

The principle was that the members followed geodesic curves in the surface, the shortest distance between two points in the curved surface although he only ever referred to it in passing as geodetic; it wouldn’t be until later the label came generally to be applied to the concept.  As a piece of engineering, it worked superbly well, having the curves form two helices at right angles to one another, the geodetic members became mutually supporting, rendering the overall framework immensely strong as well as comparatively light.  Revolutionary too was the space efficiency; because the geodetic structure was all in the outer part of the airframe meant that the centre was a large empty space, ready to take payload or fuel and the inherent strength was soon proven.  While conducting the usual wing-loading stress tests to determine the breakage point, the test routine was abandoned because the wings couldn’t be broken by the test rig.

Vickers Wellseley.

The benefits inherent in the concept were soon demonstrated.  Vickers’ first geodesic aircraft, the Wellesley, entered service in 1937 and in 1938, three of them, making use of the massive fuel capacity the structure made possible, flew non-stop from Ismailia in Egypt to Darwin in Australia, setting a new world record distance of 7,158 miles (11,265 km), an absolute record which stood until broken in 1946 by a Boeing B-29 Superfortress; it remains to this day the record for a single-engined aircraft with a piston engine, and also for aircraft flying in formation.  While the Wellesleys were under construction, Wallis designed a larger twin-engined geodetic bomber which became the Vickers Wellington, the mainstay of the RAF’s Bomber Command until 1943 when the new generation of four-engined heavy bombers began to be supplied in in the volume needed to form a strategic force.  Despite that, the Wellington was still used in many roles and remained in production until after the end of hostilities.  Over eleven-thousand were built and it was the only British bomber to be in continuous production throughout the war.

The final aircraft of the type, with a more complex geodetic structure was a four-engined heavy bomber called the Windsor but testing established it didn’t offer significantly better performance than the heavies already in service, and the difficulties which would be caused by trying to replicate the servicing and repair infrastructure was thought too onerous so it never entered production.  Post-war, higher speeds and operating altitudes with the consequent need for pressurised cabins rendered the fabric-covered geodetics obsolete.

Aston Martin DB4 GT Zagato (one of 19 in the "Continuation Series", production of which began in 2019) during construction, an aluminium panel being attached to the superleggera frame, Aston Martin Works, Newport Pagnell, Buckinghamshire, England.

There are obvious visual similarities between the classic superleggera method and the geodesic structure used in airframes and some buildings, most famously the “geodesic dome”.  The imperatives of both were strength both aim to create strong and lightweight structures, but they differ in their specific design and application.  As used in airframes, the geodesic structure consisted of a network of intersecting diagonal braces, creating a lattice framework which distributed loads as evenly as possible while providing a high strength-to-weight ratio.  This was of great significance in military airplanes used in combat because it enhanced their ability better to withstand damage better, the stresses distributed across the structure rather than being restricted to a limited area which could create a point-of-failure.  The geodesic framework was based on geometric principles which had been developed over centuries and typically employed hexagons & triangles to render a structure which was both rigid & light.  Superleggera construction differed in that it involves the creation of a lightweight tubular frame, covered with aluminum body panels of a thinness which wouldn’t have been possible with conventional engineering.  The attraction of the superleggera technique was the (relatively) minimalistic framework supported the skin, optimizing weight reduction without compromising strength.  So, structurally, the difference was the geodesic design used a network of intersecting braces to form a lattice, while the superleggera construction used a tubular frame covered with panels.

Funicular

Funicular (pronounced fyoo-nik-yuh-ler)

(1) Of or relating to a rope or cord, or its tension.

(2) Worked by a rope or the like.

(3) In physics and geometry, the curve an idealized hanging chain or cable assumes under its own weight when supported only at its ends (also known as a catenary).

(4) A type of cable car, usually described as a funicular railway which tends to be constructed on steep slopes and consist of a counterbalanced car sat either end of a cable passing round a driving wheel at the summit.

(5) Of or relating to a funicle.

(6) In medicine, of or pertaining to the umbilical cord.

(7) In botany, having a fleshy covering of the seed formed from the funiculus, the attachment point of the seed.

1655-1665: From the Latin funicle (a small cord) from the Latin funiculus (a slender rope), diminutive of funis (a cord, rope) of unknown etymology but possibly related to the Latin filum (thread), a doublet of file and (in anatomy), a filamentous anatomical structure.

The Funicular Railway

Castle Hill Funicular, Budapest, Hungary.  Opened in 1870, It ascends and descends 167 feet (51m) through a track of 312 feet (95m) in around ninety seconds.

A funicular railway employs (usually) two passenger vehicles pulled on a slope by the same cable which loops over a pulley wheel at the upper end of a track.  The vehicles are permanently attached to the ends of the cable and counterbalance each other. They move synchronously: while one is ascending, the other descends.  The use of two vehicles is what distinguishes funiculars from other types of cable railways although more complex funiculars have been built using four.  The first was built in 1874.

In 1943, Benito Mussolini (1883-1945; Duce (leader) & prime-minister of Italy 1922-1943) was deposed by a meeting of the Fascist Ground Council, a kind of senate he'd made the mistake of not dissolving when he had the chance.  In farcical circumstances, the Duce was arrested and spirited away and almost immediately, Fascism in Italy "burst like a bubble", a not inaccurate assessment but one which caused some embarrassment to Colonel-General Alfred Jodl (1890–1946; Chief of the Operations Staff OKW (Oberkommando der Wehrmacht (high command of the armed forces)) 1939-1945) who made the mistake of blurting it out in the presence of  Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945).  Not wanting the contagion to spread, Hitler ordered Mussolini be rescued so he could be established as a "puppet Duce" somewhere to try to preserve the illusion the "pact of steel" between the two fascist states remained afoot.    

Seeking a place to imprison the deposed Duce secure from any rescue attempt, the new Italian government locked him up at the Hotel Campo Imperatore, a mountain resort in Abruzzo accessible only by a funicular railway, judged (correctly) by the military authorities to be easily defensible against ground troops and without the facilities to support landings by aircraft.  However, a rapidly improvised operation using glider-borne Waffen-SS troops and a STOL (short take-off & landing) airplane staged a daring raid and freed the captive though it proved a brief reprieve, the Duce and his mistress executed by a mob less than two years later.

Fieseler Fi 156 Storch, Gran Sasso d'Italia massif, Italy, during the mission to rescue Mussolini from captivity, 12 September 1943.  The Duce is sitting in the passenger compartment.

The German liaison & communications aircraft, the Fieseler Fi 156 Storch (stork) was famous for its outstanding short take-off & landing (STOL) performance and low stalling speed of 30 mph (50 km/h) which enabled it almost to hover when faced into a headwind.  It was one of the classic aircraft designs of the era and so close to perfect it remained in production for years after the end of hostilities and re-creations are still often fabricated by those attracted by its close to unique capabilities.  The Storch’s ability to land in the length of a cricket pitch (22 yards (20.12 m)) made it a useful platform for all sorts of operations and while the daring landing on for a mountain-top rescue-mission in northern Italy was the most famous, for all of the war it was an invaluable resource; it was the last Luftwaffe (German air force) aircraft to land in Berlin during the last days of the Third Reich.  In 1943, so short was the length of the strip of grass available for take-off that even for a Storch it was touch & go (especially with the Duce’s not inconsiderable weight added) but with inches to spare, the little plane safely delivered its cargo.

In one of the war's more obscure footnotes, it was the characteristics of the Fieseler Storch which led to what was may have been the first appearance (in writing) for centuries of an old piece of Middle English slang, dating from the 1590s.  In sixteenth century England, the ability of the Kestrel (a common small falcon) to hover in even a light breeze meant it came to be known (in certain circles) as "the windfucker" and the similar ability of the Storch was noted in one British wartime diary entry in which the folk-name for the bird was invoked to describe the little aircraft seemingly "hanging in the air".

Ersatz

Ersatz (pronounced er-zahts or er-sahts)

(1) Serving as a substitute; synthetic; artificial (adjective).

(2) An artificial substance or article used to replace something natural or genuine; a substitute (noun).

1875: From the German ersatz (units of the army reserve (literally "compensation, replacement, substitute"), a back-formation from ersetzen (to replace; substitute good) from the Old High German irsezzen, the construct being ir- (an unaccented variant of ur; in German, the prefix signifying a notion of getting something (either by conscious effort or (rarely) producing the effect of coming to have it unintentionally) by specific means) + setzen, from the Middle High German setzen, from the Old High German sezzen, from the Proto-Germanic satjaną, from the primitive Indo-European sodéyeti; from the primitive Indo-European root sed- (to sit); it was cognate with the Hunsrik setze, the English set and the Dutch zetten.  Historically an adjective, use of ersatz as a noun was first noted in 1892.

Technically, although ersatz has many synonyms (synthetic, phony, imitation, fake, sham, substitute, counterfeit, bogus, manufactured, pretended, simulated, spurious, copied, false et al), because of its association with inferior quality goods (such as chocolate and, most famously, the notoriously unpleasant ersatz coffee, made typically from acorns), produced in Germany during the world wars to compensate for the shortage of genuine products, Ersatz tends to be used in that context while the preferred terms in modern English use are fake & faux, the latter with the particular sense of something imitative yet deliberately not deceptively so.  Indeed, faux can have positive connotations (faux fur, leather etc) and, among vegans, such things may be obligatory. 

Originally, the German military jargon was Ersatz Corps which described reserve, substitute or replacement troops, the word later adopted by the Kaiserliche Marine (the Imperial Navy) as part of the secrecy protocol which didn’t reveal the names of vessels until launch (and, in war-time, even during sea-trials), ships thus appearing in the naval lists with names like "Ersatz Yorck class".  During the two world wars, it was most famously applied to over ten-thousand substitute products, both industrial and consumer goods, created because of shortages.  The word entered Russian and English and came to describe any product thought not as good as the original.

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 of 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".

Agreeing 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 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) 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.

Schematic of Ersatz Yorck's armor deployment.

Ersatz Yorck was one of the project names for a planned build of three battlecruisers ordered in 1916 by the German navy.  After the first keel had been laid down, influenced by the tendency, noted since the launching a decade earlier of the Royal Navy's HMS Dreadnought, towards bigger guns, the design was revised to become was significantly heavier than the Mackensen class which had been the original template.  The name Ersatz Yorck was derived from the ship being the replacement (ie ersatz in the original German sense of the word) for the Roon class armored cruiser SMS Yorck, sunk in home waters in 1914 after striking a (German) mine.  The other two ships in the programme were Ersatz Gneisenau & Ersatz Scarnhorst, both slated as replacements for namesakes lost during the Battle of the Falkland Islands (1914).

The three ships were never completed because it had become apparent augmenting the surface fleet was reinforcing failure and that U-boat (submarine) construction was a better use of available resources.  Thus the partially built Ersatz Yorck, years from completion, was broken up on the slipway and cannibalized to support U-boat production.  However, the navy retained the blueprints and it was these plans which in the 1930s provided the basis for what became the Scarnhorst class battleships although, in the Second World War, the illusion a surface fleet would be a more effective instrument of war at sea than the U-Boats proved again a chimera and one which meant that even in the early days of the conflict, the British never quite lost control of the Atlantic.  Had Germany entered the war with the 300 operational submarines advocated by the navy's U-Boat branch rather than the two-dozen odd available in 1939, the battle in the Atlantic would have have assumed a different character.
