Bandage

Bandage (pronounced ban-dij)

(1) A strip of soft cloth or other material used to bind up a wound, sore, sprain etc, or as a protective compression device to prevent or limit injury.

(2) Anything used as a band or ligature.

(3) To bind or cover with a bandage; to put a bandage on a wound, sprain etc, or as a protective compression device to prevent or limit injury.

(4) In fashion, a type of dress, distinguished from similar styles by the use of knitted fabrics.

(5) Figuratively, by extension, a provisional or makeshift solution that provides insufficient coverage or relief (also as band-aid solution).

1590-1600: From the Middle English bandage (strip of soft cloth or other material used in binding wounds, stopping bleeding etc), from the sixteenth century French bandage, from the Old French bander (to bind), from bande (a strip).  The verb bandage (to dress a wound etc, with a bandage) dates from 1734 (and was implied in bandaging).  Bandage is the spelling in Danish, Dutch, German, English & Swedish but other languages localized the French including Norwegian Bokmål (bandasje) Polish (bandaż) & Turkish (bandaj).  The spelling in the constructed Esperanto is bandaĝo.  The noun bandager really does appear in first-aid manuals but bandagist (one who sells bandages) is now rare.  Other words used in similar vein include dressing, gauze, plaster, swathe, truss, compress, bind & wrap.  Bandage & bandaging are nouns & verbs, bandager & bandagist are nouns, bandaged is a verb & adjective and bandagelike is an adjective; the noun plural is bandages.

The noun compress, (in the surgical sense of "soft mass of linen or other cloth to press against some part of the body (with the aid of a bandage)”), as an adaptation from the earlier verb, evolved in the 1590s in parallel with bandage.  In earlier use, the noun ligament (band of tough tissue binding bones) was a late fourteenth century creation from the Latin ligamentum (a band, bandage, tie, ligature), from ligare (to bind, tie), from the primitive Indo-European root leig- (to tie, bind) and in the medical literature, ligamental, ligamentous & ligamentary still occasionally appear.  One technical term from medicine which seems extinct is the verb deligate (to bind up, bandage), noted since 1840 (and implied in deligated), from the Latin deligatus (bound fast), from deligare (to bind fast), the construct being de- (from the Latin dē-, from the preposition dē (of, from); the Old English æf- was a similar prefix) + ligare (to bind).  Under the Raj, the noun puttee (long strip of cloth wound round the lower leg as protection by soldiers) enjoyed a evolution in spelling typical of many words in British India, patawa in 1875, puttie by 1886 and the modern puttee finally (more or less) standardized by 1900).  The source was the Hindi patti (band, bandage) from the Sanskrit pattah (strip of cloth).  The noun fascia did have a brief career in medicine, being from the Latin fascia (a band, bandage, swathe, ribbon), derivative of fascis (bundle (which as fasces became a familiar form in the twentieth century)).  In English, the original use was in architecture, the anatomical application not noted until 1788 and it’s now also a familiar form in botany, music, astronomy and interior design, most obviously in cars.  The noun bandeau (headband), now much associated with revolutionaries (and in fashion the emulation) dates from 1706, from the French bandeau, from the twelfth century Old French bandel & bendel (bandage, binding), a diminutive of bande (a band, a strip).  As a style of women's top or bra, it was first described in 1968 and is distinguished from similar styles in being of a rectangular cut, the hems forming two horizontal lines above and below the breasts.

The bandage dress

Model Charlotte McKinney (b 1993) in red bodycon dress, 2018.  This one is not a true "bandage" because it's not constructed with the horizontal cuts of fabric (al la a wrapped bandage).

Although the motif of what is called the bandage dress is clearly identifiable in depictions of women pre-dating Antiquity, the creation of the modern commercial product is credited to the 1980s work of Tunisian couturier Azzedine Alaïa (1935-2017) but it is with French designer Hervé Peugnet’s (1957–2017) fashion house Hervé Léger that the style is now most associated.  The bandage dress is a specific interpretation of the earlier, figure-hugging bodycon dress, the name originally a contraction of "body conscious" which the industry would later morph into "body confidence" (a movement forgotten as soon as GLP-1 (glucagon-like peptide-1) appetite-suppressant drugs entered mainstream availability) in reaction to criticism and in Japan, they were marketed as ボディコン (bodikon), a spelling better suited to traditional pronunciation in Japanese.

Model Kate Upton (b 1992) in bandage dress, 2011.  Quite how the predominate color should be described will divide opinion.  Most would probably settle on “purplish-gray” although something like “dusky plum-grey” would appeal to those in the marketing department; it could be called “mauve” but usually that implies a lighter hue.  This one is a genuine “bandage”, distinguished by being built from form-hugging horizontal sections of fabric.

What distinguished bandage from bodycon was the fabric, the former made not with anything woven, engineered instead to compress using machine-knitted material, the completed panels left uncut and assembled to created the finished item.  Bandage dresses thus, although truly suitable for only one body type, because of the compression effect of the knitted fabric, do (slightly) extend the parameters of the silhouette which can be accommodated while still being aesthetically successful whereas bodycon dresses made from fabrics which merely cling rather than smooth out imperfections rely on an ideally formed frame.  For that reason, the jocular slang “body compression” was sometimes used to describe this sub-set of the bodycon, the bandage dress working like externally worn shapewear, corset-like in effect if not quite an actual exoskeleton.

Lindsay Lohan (b 1986) in bodycon dress with fishnet stockings, 2008.  Visually, this one is a bit of a hybrid because, although not built-up with fabric layers, the "bandage-look is emulated with stitched-folds.  When worn by someone with a flawless figure, the "corrective" tricks of the bandage construction are not demanded.  

Hervé Léger in 1992 first displayed the bandage dresses which would come to be the style’s definitive look; instantly popular, they were a red-carpet staple well into the twenty-first century.  Still a big seller, the bandage dress in 2015 migrated, via the twittersphere, from the fashion section to the front page when the comments of Patrick Couderc (b 1961, then managing director of Hervé Léger's British distributor, MJH Fashion), were published.  In an interview with the Daily Mail on Sunday, Mr Couderc made it clear he’d prefer it if some women would avoid buying Hervé Léger’s most famous creation, those on the proscribed list including lesbians, those beyond a certain age and anyone with a less than ideal silhouette.

There was an element of classism too in his critique as he lamented the growing popularity of the bandage dress, too many now seen on the wrong-shaped customers and worse still, they were often cheap knock-offs of the £1,300 (US$1600) originals and thus increasingly associated with reality TV stars and those working in hair salons.  Admitting dryly “you can be a victim of your success”, his comments seemed to echo those reported earlier in the century by the distributers of a high-end cognac and the Maybach, Daimler-Benz’s ill-fated mistake in thinking what was needed was a brand above Mercedes-Benz which, for almost a century, had been good enough for presidents, popes and potentates.  Then the complaint had been that drink and car were finding favor with hip-hop & rap stars and this most interpreted as an expression of concern the association with people of color might “cheapen the brand”.  Mr Couderc didn’t comment on skin color but told The Mail he refuses to give free dresses to celebrities if they are “judged to lack sufficient class”.

Clearly a student of the interplay of sociology and economics, he allowed his mind to wander wide, recalling that he’d “...never go out to dinner if she’s not wearing tights.  I think hosiery is something which is very magical in my world and I’m veering off into complete poetry now.  But it’s a social statement because in the 1980s, the difference between someone who was wearing tights and someone who was not was very significant.”  Clearly nostalgic for a time when the poor were less inclined to get ideas above their station, he added that then, “...whoever was wearing tights was working in a private office in a bank in St James’s and whoever was not wearing tights was coming to work as a shampooist in a High Street hairdresser, commuting from Croydon.  We were living in a time where the distinction between the two social strata was much more significant than today”.  How he must long for that vanished, pre-1945 world, when folk from Croydon were deferential to their betters.

Actor Salma Hayek (b 1966) in lavender bandage dress, 1998.

The attitude was hardly unique in the industry, Abercrombie & Fitch early in the century re-built into a highly profitable company using a model former CEO Mike Jeffries (b 1944) described in a 2006 interview as “exclusionary” noting their clothes were a product in which “a lot of people don’t belong and they can’t belong.”  That really wasn’t an unusual business model but it was rare for a CEO so bluntly to state the obvious and, when the comments were published in 2013, Mr Jeffries issued a apology saying "We are completely opposed to any discrimination, bullying, derogatory characterizations or other anti-social behavior based on race, gender, body type or other individual characteristics".  Also controversial was a later comment, attributed in 2013 to (an unnamed) Abercrombie and Fitch district manager.  It’s said the person being interviewed requested anonymity so the statements have never been verified but it was reported that when asked how the company responds to non-profits asking for donations of discontinued clothing to be given to the poor and homeless, the reply was “Abercrombie and Fitch doesn’t want to create the image that just anybody, poor people, can wear their clothing. Only people of a certain stature are able to purchase and wear the company name”, to which he added they would rather “burn the clothes” than risk them being seen on the backs of the poor.  Again, while rarely discussed, the practice of destroying rather than discounting or giving away unsold or discontinued items is widespread in the industry.  In 2024, Mr Jefferies was indicted in the US on criminal charges of sex trafficking and interstate prostitution of young men.  In 2025, a judge accepted a motion filed by the prosecution and defense saying Mr Jeffries was suffering from advanced dementia and Alzheimer's disease and was thus not competent to stand trial.  After a period of assessment in hospital at the FMC (Federal Medical Center), in November 2025 he was released from custody but, surprising some, within a month prosecutors informed the court Mr Jeffries had been re-assessed after treatment and was now fit to stand trial; in August 2026 this was accepted by the court and a hearing date is expected soon to be announced.

Speaking at Hervé Léger’s boutique in Knightsbridge, Central London, the like-minded Mr Couderc wasn’t entirely lacking in empathy, noting “You women have a lot of problems. You will lose the plot.  You will come and you will put a dress on and you’ll be in front of the mirror, like, ‘Argh, I’m so fat’”.  “Yes, you have a 12th of an inch around your stomach, it’s not really a disaster, and what you’re not noticing is that your cleavage is about two inches too low because you are 55 and it’s time that you should not display everything like you’re 23.”  At this point he did concede the particular virtue of the bandage dress was it could in such cases “provide useful support” but that didn’t mean he approved.

How a Hervé Léger bandage dress should hang.

He’d clearly thought about things, his advice to lesbians (presumably young or old) that “if you’re a committed lesbian and you are wearing trousers all your life, you won’t want to buy a Léger dress.  Lesbians would want to be rather butch and leisurely.”  Warming to the topic, he went on to say “voluptuous” women (most drawing the inference he meant "not slender") and those with “very prominent hips and a very flat chest” should wear something else, adding the handy hint that women must not wear underwear that was too small, because “the knicker line cuts through the flesh and goes through the other side of the dress” thereby creating the dreaded VPL “visible panty line.”

Hervé Léger’s Moscow store.

Quite what he thought the reaction to his comments would be isn’t recorded but while his views may not much have changed since the 1980s, much of the rest of the world now has the means to respond en masse and what should have been the foreseen twitterstorm (X used to be called Twitter) quickly gathered, the hashtags  #boycottherveleger & #wecanwearwhateverthefuckwewant soon trending.  Doubtlessly fearing the "righteous wrath and indignation" of blood-thirsty lesbians, those not slender, chav shampooists and women of a certain age, Max Azria’s (1949-2019) BCBGMAXAZRIA Group (that in 1998 had acquired Hervé Léger), went immediately into crisis management mode, issuing a statement saying they were “...shocked and appalled by Patrick Couderc’s comments made in the Mail on Sunday.  BCBGMAXAZRIA Group is working in concert with MJH Fashion, the London-based licensee of the Herve Leger brand, to investigate and establish appropriate next steps. The statements made by Mr Couderc are not a reflection of Herve Leger by Max Azria or MJH Fashion ideals or sentiments.”  The Herve Leger by Max Azria brand celebrates sensuality, glamour and femininity without discrimination.”  Less than 24 hours later, MJH Fashion confirmed Mr Couderc was no longer employed by the company.  Max Azria (1949–2019) in 2016 ended his connection with BCBGMAXAZRIA and its associated companies and in 2017 the group filed for Chapter 11 bankruptcy protection, the intellectual property rights and assets later acquired by the Marquee Brands division of the Global Brands Group.  Bandage dresses remain popular.

Foxbat

Foxbat or fox-bat (pronounced foks-bat)

(1) As Foxbat, the NATO (North Atlantic Treaty Organization) reporting name for the Soviet-era MiG-25 (Mikoyan-Gurevich MiG-25) high-altitude supersonic interceptor and reconnaissance aircraft.

(2) A common name for members of the Megachiroptera (the Pteropus (suborder Yinpterochiroptera), a genus of megabats), some of the largest bats in the world.

Fox is from the Middle English fox, from the Old English fox (fox), from the Proto-West Germanic fuhs, from the Proto-Germanic fuhsaz (fox), from the primitive Indo-European púḱsos (the tailed one), derive possibly from puḱ- (tail).  It was cognate with the Scots fox (fox), the West Frisian foks (fox), the Fering-Öömrang North Frisian foos, the Sölring and Heligoland fos, the Dutch vos (fox), the Low German vos (fox), the German Fuchs (fox), the Icelandic fóa (fox), the Tocharian B päkā (tail, chowrie), the Russian пух (pux) (down, fluff), the Sanskrit पुच्छ (púccha) (source of the Torwali پوش‎ (pūš) (fox) and the Hindi पूंछ (pūñch) (tai”).

Bat in the context of the animal was a dialectal variant (akin to the dialectal Swedish natt-batta) of the Middle English bake & balke, from the North Germanic. The Scandinavian forms were the Old Swedish natbakka, the Old Danish nathbakkæ (literally “night-flapper”) and the Old Norse leðrblaka (literally “leather-flapper”).  The Old English word for the animal was hreremus, from hreran (to shake) and it was known also as the rattle-mouse, an old dialectal word for "bat", attested from the late sixteenth century.  A more rare form, noted from the 1540s, was flitter-mouse (the variants were flinder-mouse & flicker-mouse) in imitation of the German fledermaus (bat) from the Old High German fledaron (to flutter).  In Middle English “bat” and “old bat” were used as a (derogatory) term to describe an old woman, perhaps a suggestion of witchcraft rather than a link to bat as "a prostitute who plies her trade by night".  It’s ancient slang and one etymologist noted the French equivalent hirondelle de nuit (night swallow) was "more poetic".  To “bat the eylids” is an Americanism from 1847, an extended of the earlier (1610s) meaning "flutter (the wings) as a hawk", a variant of bate.  Fox-bat is a noun; the noun plural is fox-bats.  When used of the MiG-25 (as "Foxbat", the NATO reporting name), it's a proper noun and thus used with an initial capital.

Fox-bat in flight.

The term fox-bat or flying fox, (genus Pteropus), covers some sixty-five bat species found on tropical islands from Madagascar to Australia and north through Indonesia and mainland Asia.  Most species are primarily nocturnal and are the largest bats, some attaining a wingspan of 5 feet (1.5 m) with an overall body length of some 16 inches (400 mm).  Zoologists list fox-bats as “Old World fruit bats” (family Pteropodidae) that roost in large numbers and eat fruit and are thus a potential pest, many countries restricting their importation.  Like nearly all Old World fruit bats, flying foxes use sight rather than echolocation, a physiological process for locating distant or invisible objects (such as prey) by means of sound waves reflected back to the emitter by the objects) to navigate, despite the largely nocturnal habit of most species.  In the database maintained by the International Union for Conservation of Nature and Natural Resources (IUCN), about half of all flying fox species are listed as suffering declining populations, 15 said to be vulnerable and 11 endangered. The fox-bats were previously classified in the suborder Megachiroptera, but most researchers now place them in the suborder Yinpterochiroptera, which also contains the superfamily Rhinolophoidea, a diverse group that includes horseshoe bats, trident bats, mouse-tailed bats, and others.

MiG-25 (Mikoyan-Gurevich MiG-25).

Once the most controversial fighter in the skies, there was so much mystery surrounding the MiG-25 that US, British and NATO planners spent years spying on it with a mixture of awe and dread.  Conceived originally by Soviet designers to counter the threat posed by Boeing’s B-70 Valkyrie bomber, development continued even after the B70 project, rendered redundant by advances in missile technology, was cancelled.  First flown in 1964 and entering service in 1970, nearly 1200 were built and were operated by several nations as well as the USSR.  Able (still) to outrun any other fighter, only the US Lockheed SR-71 Blackbird was faster but fewer than three dozen of those were built and those were configured only for strategic reconnaissance.  When first the West became aware of the Foxbat, it caused quite a stir because, combining stunningly high speed with high altitude tolerance and a heavy weapons load, it did appear to be the long-feared platform which would render Soviet airspace immune from US penetration.  It was the threat the Foxbat was thought to pose which was influential in the direction pursued by US engineers when developing the McDonnell Douglas F15.

The Foxbat however never realized its apparently awesome implications. Because the original design brief was to produce a device which could combat the fast, high-flying B-70, many of the characteristics desirable in a short-range interceptor were neglected in the quest for something which could get very high, very quickly.  At that it was a breathtakingly successful but there were compromises, the fuel burn was epic and, with a very high take-off and landing speed, it could operate only from the longest runways.  Still, at what it was good at it was really good and its very presence meant the US had to plan any mission within range of a Foxbat, cognizant of the threat it was thought to present.  Unbeknown to the West, at lower altitudes it presented little threat and was no dog-fighter; it was essentially a dragster built for the skies, faster in a straight line than just about anything but really not good at turning.  Its design philosophy was essentially the same as the Lockheed F-104 Starfighter, a US supersonic interceptor which first flew in 1954 with over 2,500 built and supplied to many air forces, the last of which wasn’t retired from active service until 2004.  An uncompromising machine built for speed, pilots dubbed it the “winged missile” and that assessment was not unrelated to it later gaining the nickname “widow-maker”; those who flew the thing described the characteristics it exhibited in low speed turns as: “banking with intent to turn”.

It wasn’t until 1976 when a Soviet defector landed a new Foxbat in Japan in 1976 that US engineers were able to examine the airframe and draw an understanding of its capabilities.  What their analysis found was that the limitations in Soviet metallurgy and manufacturing techniques had resulted in a heavy airframe, one which really couldn’t maneuver at high speeds, and handled poorly at low altitudes. The surprisingly primitive radar was of limited effectiveness in conventional combat situations against enemy fighters, which, combined with the low altitude clumsiness meant that its drawbacks tended to outweigh the advantage it had in sheer speed at altitude, something which meant less to the US since missiles had replaced the B-70 strategic bomber (which never entered production).

In its rare combat outings, those advantages did however confer the occasional benefit.  In 1971, a Soviet Foxbat operating out of Egypt used its afterburners to sustain Mach 3 for an extended duration, enabling it to outrun three pursuing Israeli F4-Phantoms and one downed a US Navy F/A-18 Hornet during the first Gulf War (1991).  During the Iran-Iraq War (1980-1988), the Iraqi Air Force found them effective against old, slow machinery but sustained heavy losses when confronted with the Iran’s agile F-14 but most celebrated was probably the Foxbat’s success during the Gulf War in claiming both of the last two American aircraft lost in air-to-air combat.  Otherwise, the Foxbat has at low altitude proved vulnerable, the Israeli Defense Force (IDF) shooting down several in the war over Lebanon (1981) although they have of late been used, most improbably, in a ground attack role in the Syrian Civil War, the Syrian Arab Air Force, lacking a more appropriate platform, pressing the Foxbats into a ground support role, in at least one case using air-to-air missiles to attack ground targets.  The Soviet designers took note of the operating environment when developing the Foxbat’s successor, the MiG-31 (NATO reporting name Foxhound), a variant which sacrificed a little of the pure speed and climb-rate in order to produce a better all-round fighter.

Usually unrelated: 1957 Morris Minor Traveller (left) and 1960 Jaguar XK150 FHC (right).  Stations wagons with wood frames (real and fake) are in the US called "woodies" but the spelling "woody" also appears in UK use.  Although between 1968-1973, there were “badge-engineered” Versions of the Minor’s commercial derivatives sold as the Austin 6cwt & 8cwt Van & Pick up, all the “woodies” were Morris Travellers.

Although for the whole of the Jaguar XK150’s production run (1957-1961) the Morris Minor Traveller (1952-1973) was also being made in factories never more than between 20-60 odd miles (32-100 km) distant, so different in form and function were the two it’s rare they’re discussed in the same context.  One was powered by an engine which had five times won the Le Mans 24 hour endurance classic while the other was one of several commercially-oriented variants of a small, post-war economy car, introduced in the austere England of 1948.  The Traveller did however have charm and it was also authentic in its construction, the varnished ash genuinely structural, an exoskeleton which provided the strength while the panels behind were there just to keep out the rain.  By contrast, by the mid-1950s, the US manufacturers had abandoned the method and produced “woodies” with a combination of fibreglass (fake timber) and DI-NOC, (Diurno Nocturna, from the Spanish, literally “daytime-nighttime” and translated for marketing purposes as “beautiful day & night”) appliqué, an embossed vinyl or polyolefin material with a pressure-sensitive adhesive backing produced since the 1930s and perfected by Minnesota Mining & Manufacturing (3M).

In phased releases over 1957-1958, Jaguar made available the usual three versions of its XK sports car, the DHC (drophead coupé, a style which elsewhere was usually called a cabriolet or convertible) and FHC (fixed head coupé, ie coupé), later joined by the more minimalist OTS (open two-seater, a roadster) and the line was a link between flowing lines of the inter-war years and the new world, celebrated by the E-Type (1961-1974) which created such a sensation upon debut at the 1961 Geneva Motor Show.  One sometimes unappreciated connection between the XKs (XK120: 1948-1954, XK140: 1954-1957 & XK150: 1957-1961) and E-Type is neither was envisaged as the long-term model both became.  The XK120 had been shown at the 1948 London Motor show with the purpose of drawing attention to the new XK straight-six (which would serve in vehicles as diverse as racing cars, limousines and fire engines until 1992) but such was the public response it was added to the factory catalogue, the early models hurriedly built in aluminium to satisfy demand.  Later, Jaguar hadn't believed there would be a market for more than a few hundred E-Types so it was not designed in a way optimized for mass-production which was embarked upon only because demand was so high.  Many of the car's quirks and compromises remained part of the structure until the end of production more than a decade later.   

Minor modification: 1960 Jaguar XK150 3.4 Shooting Brake (“Foxbat”).

The Morris Minor Traveller was the last true woodie in production and is now a thing in the lower reaches of the collector market but there's one less available for fans because of a sacrifice to a project by industrial chemist and noted Jaguar enthusiast, the late Geoffrey Stevens, construction undertaken between 1975-1977. He wanted the Jaguar XK150 shooting brake the factory never made so blended an XK150 FHC with the rear compartment of a Morris Minor Traveller of similar vintage.  Mr Stevens in 1976 dubbed his creation “Foxbat” because, just as a MiG-25 landing in Japan was an event so unexpected it made headlines around the world, he suspected that in the circles he moved, a timber-framed XK150 shooting brake would be as much a surprise.  In that he proved correct and the unique shooting brake has been restored as a charming monument to English eccentricity, even the usually uncompromising originality police among the Jaguar community (mostly) fond of it.  In a nice touch (and typical of an engineer’s attention to detail), a “Foxbat” badge was hand-cut, matching the original Jaguar script.  Other than the hybrid coach-work, the XK150 is otherwise “matching-numbers” (chassis number S825106DN; engine number V7435-8).   

On the Wings of a Russian Foxbat: Deep Purple bootleg, 1977.

The origin of the term “bootlegging” dates from the late eighteenth century when it was used by British customs and excise officers to describe the trick smugglers used hiding valuables in their large sea-boots.  Since then, it’s been applied variously including (1) the distilling, transporting and selling of unlawful liquor (2) unlicensed copies of software and (3) unauthorized recordings of music and film.  In music, bootleg recordings began to appear in some volume in the 1960s and originally were often from live performances.  Often created from tapes of dubious quality with little or no editing, these bootlegs generally were tolerated by the industry because they tended to circulate among fans who anyway purchased the official product and were thought of just a form of free promotional material.  Later, when things became more organized and bootleggers began distributing replicas of official releases, the attitude changed and for decades the software industry fought ongoing battles against bootleg copies (which in some non-Western markets represented in excess of 90% of installations).

On the Wings of a Russian Foxbat, re-released (in re-mastered form with bonus tracks) in 1995 as Live in California, Long Beach Arena, 1976.

Taken from a performance by the English heavy metal band Deep Purple at the Long Beach Arena, Los Angeles on 27 February 1976, the bootleg On the Wings of a Russian Foxbat was released in 1977 and was another example of the effect on popular culture of the Soviet pilot’s defection.  The link with the event in Japan was that the quality of the band’s performance was unexpectedly good, their reputation at the time not good (they would break-up only weeks after the Long Beach show).  Additionally, the sound quality was outstanding (certainly by the usual bootleg standards), something not then easy to achieve in an outdoor venue with a raucous audience.  Curiously, the original On the Wings of a Russian Foxbat bootleg used for the cover art a picture of unsmiling soldiers from the PLA (People’s Liberation Army) from the Republic of China (then usually called “Red China” or “Communist China); presumably the bootleggers decided the star on the caps was “sufficiently Russian”.  In 1995, re-mastered, the recording (with a few bundled “extras”) was re-issued as an “official” release, the fate of many a bootleg with a cult-following.  With memories of the diplomatic incident in 1976 having faded, although On the Wings of a Russian Foxbat still appeared on the cover, the album was marketed as Live in California, Long Beach Arena, 1976.

Exoskeleton & Endoskeleton

Exoskeleton (pronounced ek-soh-skel-i-tn)

(1) In zoology, an external covering or integument, any hardened external structure, as the shells of crustaceans or the scales and plates of fishes and reptiles, especially when it is of the nature of bone.

(2) All hard parts, such as hair, teeth, and nails which develop from the ectoderm or mesoderm in vertebrates (generally used only in technical literature).

(3) A wearable robotic machine used for aided or augmented mobility.

1841: The construct was exo- + skeleton.  The prefix endo- was used as a word-forming element meaning "inside, within, internal.  It was from the Ancient Greek ἔνδον (éndon) (within; inner; internal) from the primitive Indo-European en-do- (an extended form of the root en (in)).  Skeleton was from the New Latin skeleton (bones, bony framework of the body), from the Ancient Greek skeleton soma (dried-up body, mummy, skeleton), from the neuter of σκελετός (skeletós) (dried up, withered, dried body (and as a noun: parched; mummy), from σκέλλω (skéllō & skellein) (dry, dry up, make dry, parch), from the primitive Indo-European (s)kelha- (to parch, wither); related was the Ancient Greek σκληρός (sklirós) (hard).  Exoskeleton is a noun; the noun plural is exoskeletons or exoskeleta.

Model Kate Upton (b 1992) making visible parts of her endoskeleton, Halloween Party, 2011.

Skelton was an early variant form.  The noun use of Greek skeletos passed into Late Latin as (sceletus), hence the French squelette and the rare English skelet (1560s), the Spanish esqueleto & the Italian scheletro.  The meaning "bare outline" was first recorded circa 1600; hence the term "skeleton crew" from 1778 used to describe minimal staffing, the skeleton key a similar allusion to some of a structure being removed.  The phrase "skeleton in the closet" (source of secret shame to a person, family or institution) is from 1812 and thought an adoption from the imagery in the fable Bluebeard (1697) by Charles Perrault (1628-1703). Exoskeleton was in 1841 coined by by English paleontologist Sir Richard Owen (1804–1892).  Exoskeleton has become more widely used in recent years because of the interest in fields such as engineering, robotics and medicine in using external structures, often to augment or replace human functions.  As early as the 1960s, the "exoskeleton look" became fashionable among architects who would no longer conceal features like plumbing pipes

Trilobite (pronounced try-low-byte) translates literally as “three lobes".  Often casually referred to as bugs or sea-bugs, in taxonomy, all trilobites actually belong in the class of trilobite in the phylum arthropod and within the class are ten orders.  It’s not known how many species of trilobites existed but almost 21,000 have thus far been identified in the fossil record, their numbers and variety leading them to be regarded as one of history’s more successful animals.  They inhabited all the seas and oceans and endured some three-hundred million years, surviving several mass-extinction events.  Their long duration, their structure and living habits meant they became a common and frequently discovered fossil, noted since antiquity although the first attempt scientifically to classify one seems to have been by Wan Shizen of China who, in 1689 described trylobite pygidia (tails) as "batstones".  The first known scientific drawing was by Welsh botanist, the Reverend Edward Lhuyd (1660-1709) whose sketch of a trilobite was published in "The Philosophical Transactions of the Royal Society.  The drawing, now classified as being a Ogygiocarella debuchii, was then (not unreasonably), called the "flatfish".

Truly ancient, trilobites pre-date the Cambrian explosion (some 540 million years ago) and went extinct only towards the end of the Permian extinction event (some 250 million years ago) which ended the Paleozoic age which had lasted some 290 million years.  However, the earlier events took their toll, a few orders vanishing after the Ordovician event (some 445 million years ago) while the Devonian event (some 370 million years ago) removed all but one order, that last survivor dying out in the Permian event.  Why such a successful and prolific creature could not endure these extinctions remains a debate, the more popular theories including (1) environmental change happening with such rapidity there was no time for evolutionary adaptation and (2) the needed sources of nutrition vanishing because organisms lower in the food-chain went extinct.  All shared the same basic structure, having three lobes: a left pleural, a middle axial and a right pleural lobe, their bodies divided into a cephalon (dead), thorax (middle), and pygydium (tail).  Trilobites had a thick, protective exoskeleton which formed a hard calcite shell, something like that of the modern crab and is the reason for their frequency in the fossil record, the exoskeletons usually the only part to survive although, in the rare cases where certain surrounding conditions exist, traces of soft tissue such as antennae can survive fossilization.  As a trilobite grew, it molted its exoskeleton, and many of the fossils which exist are molted frames rather than dead creatures.

Before & after avian intrusion: 1952 Mercedes-Benz 300 SL (W194), Carrera Panamericana, Mexico, November 1952.

In nature, exoskeletons evolved over thousands of generations through the interplay of natural selection and adaptation to prevailing environmental conditions but with man-made objects such things, in cases of immediate need, can within hours be fashioned.  Returning to the circuits for the first time since the end of World War II (1939-1945), Mercedes-Benz had enjoyed immediate success with the new 300 SL (W194) race car which, despite being underpowered, proved its mettle with a combination of robustness, reliability and outstanding aerodynamics which both increased performance and improved fuel economy.  The W194, ten of which were built, is often referred to as “the first gullwing” (although the configuration had in 1939 been seen on a one-off Bugatti and was not uncommon in aviation and nautical use) but the distinctive doors were introduced only after those enforcing the regulations of sports car at Le Mans ruled the 300 SL’s original “doors” were no such things and were merely “elaborately framed windows”.  With re-designed doors fitted, the W194 promptly delivered the factory a 1-2 result in the 1952 24 hour endurance classic.

1952 Carrera Panamericana: The winning 300 SL in the factory museum.

Concluding things that year was the third Carrera Panamericana, a gruelling endurance event of eight stages over some 3,100 km (1,925 miles) between 19-23 November.  With typical thoroughness, the factory shipped three W194s along with a large support staff and all was going well until the lead car collided with a large bird (contemporary articles variously reporting the unfortunate creature as a vulture or buzzard) which smashed through the windscreen at an impact speed in excess of 215 km/h (135 mph), stunning the co-driver and leaving him bloodied.  Shook awake, he recovered and when the car reached the service point a new windscreen was fitted and, as a precaution against other vultures (or whatever) seeking vengeance, eight metal bars were fitted, the ad-hoc birdcage designed to keep them out, not in.  Without further avian “events”, the W194 repeated the result from Le Mans by finishing 1-2 and, fully restored, the winning car is part of the collection of the Mercedes-Benz Museum in Stuttgart.

1968 London-Sydney Marathon: The 1968 Porsche 911S which finished fourth (left) and after a full restoration (right).  A zoologist would insist this is only a "semiexoskeleton" on the basis of the partial coverage. 

As all in the Northern Hemisphere understand, in Australia, on land, sea & air, all the wildlife will try to kill you.  Noting this, when Porsche’s competition department prepared its three entries for the 1968 London-Sydney they limited their concern about sharks and crocodiles to a single paragraph in the drivers’ instruction sheets and decided the main threat to the cars were wandering “giant” kangaroos and low-flying wedge-tailed eagles (a bird with a wingspan wider even than Mexico’s vultures).  The first event of its type in the modern era, the 1968 London-Sydney Marathon spanned half the globe over a distance of 12,237 miles (16,934) and the route shows how times have changed, stages in Iran & Pakistan included; neither country now places many organizers of events would include in their itineraries but in 1968, kangaroos were still deemed more a threat than terrorism.  Accordingly, the factory designed a kind of exoskeleton, a robust external roll cage which essentially was the W194’s “birdcage” but “on steroids”.  As originally conceived, the structure had been of more modest proportions and while the final result may look like “overkill”, things were “beefed up” following one of the drivers writing off a rented VW Beetle after colliding with a kangaroo during pre-event testing in Australia.  Impressed by the extent of the damage, the engineers produced an impressively strong protective cage, content that whatever else might go wrong, it wouldn’t be a kangaroo which ended the venture.  Porsche 911S #58 finished fourth, victory going to a Hillman Hunter #75, one of the more improbable machines to win an international endurance event.

1968 London-Sydney Marathon: The winning 1968 Hillman Hunter (left) and restored 1967 Pakyan 1725 (right), the Iranian variants often noted for their additional bling.  Unlike the cautious Germans, most teams fitted only rudimentary additional protection against kangaroos and such; some ruefully later casting envious glances at Porsche's exoskeleton. 

In fairness, though an unlikely competition car, the Hillman Hunter (the “mainstream” model in the “Arrow” range which would sold also as “badge-engineered” Sunbeam, Singer & Humber variants) was a success in many countries, lasting in Europe from 1966 until 1979 although its most extraordinary longevity was achieved in the Islamic Republic of Iran.  In 1966, during the reign of Mohammad Reza Pahlavi (1919–1980; last Shah of Iran 1941-1979) assembly from CKD (completely knocked down) packs had begun with the car sold as the Paykan (پیکان, Romanized as Peykān and literally “Arrow”) and, unlike many things, it survived the 1979 revolution to continue to flourish under the rule of Grand Ayatollah Ruhollah Khomeini (1900-1989; Supreme Leader, Islamic Republic of Iran, 1979-1989), full local manufacture starting in 1985.  Although theologically uncompromising, there’s no record of the Imam having complained of the presence on his assembly lines of a product from شیطان کوچک (Sheytān-e Koochak) (the UK & Israel being “Little Satan” and the US شیطان بزرگ (Sheytān-e Bozorg) “Great Satan” although in the West the terms are often misunderstood because in flavour of Shia Islam practiced in Iran, Satan is a pathetic rather than fearsome figure).  When in 1979 Grand Ayatollah Ali Khamenei (1939-2026; Supreme Leader, Islamic Republic of Iran 1989-2026) became supreme leader, the Pakyan carried on and although production of the salon finally ended in 2005, the pick-up variant continued to be sold for another decade, the last not leaving the line until almost 50 years after the first Hunter was sold in the UK.  From the modest Hunter, the ayatollah's got their money's worth.

Exoskeleton cars

MVE Exocet (left) & Exomotive’s Exocet Sport V8 (right).

Exoskeleton vehicles are numerous on farms, mine-sites and such but rarely seen on public roads.  They do though have a niche for those who want something which sacrifices just about everything (aerodynamics, weather protection, doors etc) for the nimbleness only extreme light-weight can deliver.  An example is the MVE Exocet, released for public sale in 2010.  It’s an inventive approach to the kit-car concept and takes the classic front-engined, rear-wheel drive approach, based on Mazda’s Miata (the MX-5, introduced in 1989 and a kind of clone of the Lotus Elan of the 1960s but without the problems), the advantage with the Japanese platform being its unusual sub-frame which permits the removal of the body, leaving the engine, drive-train and suspension as a rolling assembly to be transplanted to the Exocet chassis.

Because of the light weight, even when using sensible four-cylinder engines the Exocet delivers high-performance but the Americans in particular can’t resist the idea that just about any car can be improved by the installation of a V8 and quite outlandish power to weight ratios are possible.  An indicative example of Exomotive’s Exocet Sport used a 525 horsepower (LS3) version of one of the later evolutions of the small-block Chevrolet V8 which, fully fueled, weighed in at 1690 lb (767 kg, the 2026 Formula 1 regulations set a minimum dry-weight (ie excluding fuel) of 768 kg).  Because it possible to buy, off the shelf (as a “crate” engine), V8 engines with about the same power as a F1 power-plant generates, although there was be something a weight penalty, the potential does exist to build a two-seater roadster with a similar power-to-weight ratio and there are jurisdictions which even allow such a thing to be registered for use on public roads.  Opinions would differ on whether such a build is a good idea but the little machines, if the V8 was tuned more for low and mid-range torque rather than ultimate power, would seem to have great potential in competitions such as short-course events and hill-climbs although the dubious aerodynamics would render it less suited to high-speed tracks.

Art and money: Porsche 934 (left) by Benedict Radcliffe (b 1976) sold for US$249,002 while Comedian (a banana duct-taped to the wall, right) by Maurizio Cattelan (b 1960) realized US$6.2 million.

The exoskeleton concept inspired English artist and sculptor Benedict Radcliffe to create a number of small scale tubular steel sculptures in the shape of cars including the Lancia Stratos (1973-1978), Lamborghini Countach (1974-1990) and Ferrari F40 (1987-1992), mostly powdered-coated in lurid colors.  Usually, they sell for several thousand US dollars but in early 2025, one in 1:1 scale in the shape of a Porsche 934 sold for US$249,002; in a nod to history, it was painted in the same fluro-orange used for the Jägermeister livery used for the race cars in 1979-1977 and rolled on period-correct centre-locking BBS wheels shod with Avon slick tires.  At that price, it was little different from what one would pay for a new Porsche 911 GT3, straight from the showroom floor.  Still, it’s less than the US$1.5 million which is typical of what’s been paid in recent years on the rare occasions a 934 is offered for sale.  Produced between 1976-1977, Porsche built 31 934s, simply for the purpose of creating a version of the 930 (the 911 Turbo, 1975-1978) which would comply with the FIA Group 4 (GT Cars) rules (the 935 was the companion Group 5 (Special Production Cars) project).  The art market cannot be assessed with any form of conventional metrics but in paying a quarter-million odd for a tubular structure, one gets quite a lot compared with the Italian visual artist Maurizio Cattelan’s Comedian, (a banana duct-taped to the wall); a couple of months earlier, at auction, it had gone under the hammer for US$6.2 million.

Endoskeleton (pronounced en-doh-skel-i-tn)

(1) In zoology, the internal skeleton or framework of the body of an animal (generally the bony or cartilaginous skeleton of vertebrates).  Certain invertebrates, such as sponges and echinoderms, also have endoskeletons.

(2) For most (non-technical) purposes, a synonym for skeleton.

1838: The construct was endo- + skeleton  The prefix exo- was used as a word forming element in words of Greek origin meaning "outer, outside, outer part" and was used from the mid-nineteenth century.  It was from the Ancient Greek ἔξω (éxō) (outer; external) and was related to ex (out of).  Endoskeleton is used almost exclusively in the biological sciences.  For most general purposes, it’s synonymous with skeleton which is the default assumption of use because it’s familiar from humans and most familiar animals.  Endoskeleton is a noun; the noun plural is endoskeletons or endoskeleta.

The nicely defined shoulder blade and ribcage definition of Lindsay Lohan's endoskeleton.

The word endoskeleton may not have been needed had all creatures on earth had “conventional” skeletons like humans, cats, dogs, fish and such; there would have been just “skeletons”.  Of course, architects and engineers likely would have been unable to resist coining “exoskeleton” there seems no better word to describe an externally-located superstructure.  Both an endoskeleton and exoskeleton are structural frameworks to some degree (sometimes wholly) supporting and shaping an organism’s body and which form an animal evolved to adopt was a product of history and environment.  That’s best illustrated by those with hard outer shell (really the ultimate exoskeleton) which functions as a kind of armor-plate.  Among man-made objects, both models are used and easily identified although exoskeletons (such as the futtocks in nautical design) probably are more common in anything with a “skin” including buildings, aircraft and ships.

Endoskeleton cars

The Birdcage: The Maserati Tipo 60/61 (chassis #2549).

Endoskeleton cars are far from uncommon but some make the concept more obvious than others.  The Maserati Tipo 60/61 (1959-1961) gained the nickname “Birdcage” (by which it’s almost always known) because observers were much taken with the delicacy of the construction.  By the late 1950s, space-frames had become familiar to race-car builders but they were usually robust-looking arrangements whereas Maserati had rendered an intricate latticework of some 200 chromoly steel tubes welded often in triangulated form in the points of highest stress, the design delivering both lightness and rigidity.

Mercedes-Benz 300 SLR (W196S, upper) & 300 SL (W198, lower).

One of the reasons the Maserati’s skeleton looked so delicate was that the space-frame had become associated with Teutonic-flavored construction like that used by Mercedes-Benz for its 300 SL & 300 SLR.  Both shared the same method of construction but despite the names and the the visual similarity between the two, there were few common components beyond the nuts, bolts & screws.  The 300 SL (W198; 1954-1963) was a road car while the SLR (W196S; 1955) was a lengthened version of the W196R Formula One Grand Prix car with a sexy body and an enlarged (though somewhat detuned) straight-eight engine.  Despite appearing much more substantial than the Maserati's birdcage, the German space-frame was remarkably light.
