Golgotha

Golgotha (pronounced gol-guh-thuh or gol-goth-uh)

(1) In the Bible’s canonical Gospels, the hill near Jerusalem on which Jesus Christ was crucified; the ancient (and now alternative) name for Calvary.

(2) A place of suffering, sacrifice or martyrdom.

(3) A place of burial (rare and usually without an initial capital).

(4) In eighteenth & nineteenth century Oxbridge slang, rooms of the heads of the colleges (obsolete).

(5) In UK slang, a hat (an allusion to "the place of the skulls" (obsolete)).

(6) A charnel house (an alternative name for a crypt or ossuary).

(7) In the Eastern Orthodox Church, a representation of Christ crucified.

1590–1600: From the Late Latin Golgotha, from the Ancient Greek Γολγοθᾶ (Golgothâ) from the Aramaic (Semitic) גּוּלְגּוּלְתָּא‎ (gulgultā) (literally “place of the skull”) and cognate with the Hebrew gulgōleth (skull).  The hill gained the name because its shape was skull-like.  In Dutch the spelling was originally Golgota which influenced use in some early English translations of the Bible.  The use of Calvary to refer to the mount on which Christ was crucified dates from the late fourteenth century.  It was from the Latin Calvariae, Calvariae & Calvaria (related to calvus (bald)), from the Ancient Greek Kraniou topos, a translation of the Aramaic gulgultā and the Old English used Heafodpannan stow as a loan-translation.

Historians agree Golgotha lay immediately beyond Jerusalem's city walls but there’s no certainty about the exact location although the tradition of pilgrimage has since the early Medieval period focused on the southern chapels of the Church of the Holy Sepulchre, probably because the site received the imperial imprimatur within a century of Rome adopting Christianity.  However, speculation has always been encouraged by the apparently contradictory passages in surviving texts which can be interpreted in different ways, thus the suggestions of alternative sites, a matter of some interest to scholars in the field but ignored usually by most of Christendom for whom the Church of the Holy Sepulchre has for so long been a place of veneration.  Beginning in the nineteenth century, there have been archeological excavations but, two-thousand years on, the fragments and remains unearthed have provided only material for speculative interpretation.

The uncertainty about the exact location of Golgotha casts no doubt on the crucifixion of Jesus Christ as a historical event, described in the Book of Mark 15:22-27 (King James Version (KJV (1611)):

And they bring him unto the place Golgotha, which is, being interpreted, The place of a skull.  And they gave him to drink wine mingled with myrrh: but he received it not.  And when they had crucified him, they parted his garments, casting lots upon them, what every man should take.  And it was the third hour, and they crucified him.  And the superscription of his accusation was written over, THE KING OF THE JEWS.  And with him they crucify two thieves; the one on his right hand, and the other on his left.

From what was done of the slopes of Golgotha followed the resurrection, the central event of Christianity and the only vital component for if one accepts the story of the resurrection then Christianity makes sense.  If one’s faith can’t make that leap, Christianity is just another of the competing constructs of moral theology. 

For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him.  For this we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep.  For the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and the dead in Christ shall rise first:  Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.  Wherefore comfort one another with these words.  1 Thessalonians 4: 14-18 (King James Version (KJV (1611)).

Canada's Golgotha (1918), sculpture in bronze by Francis Derwent Wood RA (1871-1926), photograph by F Hilaire d'Arcis (1845-1935), Royal Academy of Arts Collection, London.

Canada's Golgotha is a sculpture in bronze depicting a Canadian soldier allegedly crucified on a barn door in occupied Belgium, surrounded by the jeering German troops responsible for the atrocity, said to have taken place in 1915.  There was during the First World War (1914-1918) an extensive catalogue of atrocity stories including some quite graphical imagery and there were an accepted part of the propaganda efforts on both sides of the conflict but the event carved by Wood was never verified, the contemporary witness statements later discredited.  Immediately after the end of hostilities, the German government objected to the sculpture being put on public display unless documentary evidence could be produced which proved the incident took place.  The Canadian government asserted such evidence was in their hands but declined to furnish copies which provoked further complaints from Berlin and ultimately, the sculpture was withdrawn from the exhibition.  It was kept in storage until 1992 and has since been exhibited though the curators were careful to explain the work was to be treated as an example of Christian art rather than something part of the historic record of war.  That didn’t prevent controversy.

Controversial too was the event remembered as the Nemmersdorf massacre, a series of atrocities against civilians perpetrated by Red Army soldiers during their advance into East Prussia in October 1944.  The German army swiftly (though temporarily) retook Nemmersdorf and gathered evidence of the violence, including a number of crucified bodies.  The material was passed to the Nazi Propaganda Ministry which immediately organized a publicity campaign illustrating this “Bolshevik Barbarism”, intending to inculcate the population with a fanatical desire to resist lest they suffer a similar fate.  However, there were still memories of the false atrocity stories from the earlier war and the Nazi’s propaganda efforts, increasingly disconnected from reality, had come to be regarded by many as the “fake news” of the day and the most notable consequence of the campaign was panic and a flood of civilians evacuating the eastern territories to trek west.

Nail

Pre 900: From the Middle English noun nail & nayl, from the Old English nægl and cognate with the Old Frisian neil, the Old Saxon & Old High German nagal, the Dutch nagel, the German Nagel, the Old Norse nagl (fingernail), all of which were from the unattested Germanic naglaz.  As a derivative, it was akin to the Lithuanian nãgas & nagà (hoof), the Old Prussian nage (foot), the Old Church Slavonic noga (leg, foot), (the Serbo-Croatian nòga, the Czech noha, the Polish noga and the Russian nogá, all of which were probably originally a jocular reference to the foot as “a hoof”), the Old Church Slavonic nogŭtĭ, the Tocharian A maku & Tocharian B mekwa (fingernail, claw), all from the unattested North European Indo-European ənogwh-.  It was further akin to the Old Irish ingen, the Welsh ewin and the Breton ivin, from the unattested Celtic gwhīnā, the Latin unguis (fingernail, claw), from the unattested Italo-Celtic əngwhi-;the Greek ónyx (stem onych-), the Sanskrit ághri- (foot), from the unattested ághli-; the Armenian ełungn from the unattested onogwh-;the Middle English verbs naile, nail & nayle, the Old English næglian and cognate with the Old Saxon neglian, the Old High German negilen, the Old Norse negla, from the unattested Germanic nagl-janan (the Gothic was ganagljan).  The ultimate source was the primitive Indo-European h₃nog- (nail) and the use to describe the metal fastener was from the Middle English naylen, from the Old English næġlan & nægl (fingernail (handnægl)) & negel (tapering metal pin), from the Proto-Germanic naglaz (source also of Old Norse nagl (fingernail) & nagli (metal nail).  Nail is a noun & verb, nailernailless & naillike are adjectives, renail is a verbs, nailing is a noun & vern and nailed is a verb & adjective; the noun plural is nails.

Nail is modified or used as a modifier in literally dozens of examples including finger-nail, toe-nail, nail-brush, nail-file, rusty-nail, garden-nail, nail-fungus, nail-gun & frost-nail.  In idiomatic use, a “nail in one's coffin” is a experience or event that tends to shorten life or hasten the end of something (applied retrospectively (ie post-mortem) it’s usually in the form “final nail in the coffin”.  To be “hard as nails” is either to be “in a robust physical state” or “lacking in human feelings or without sentiment”. To “nail one's colors to the mast” is to declare one’s position on something.  Something described as “better than a poke in the eye with a rusty nail” is a thing, which while not ideal, is not wholly undesirable or without charm.  In financial matters (of payments), to be “on the nail” is to “pay at once”, often in the form “pay on the nail”.  To “nail something down” is to finalize it. To have “nailed it” is “to perfectly have accomplished something” while “nailed her” indicates “having enjoyed sexual intercourse with her”.  The “right” in the phrase “hit the nail right on the head” is a more recent addition, all known instances of use prior to 1700 being “hit the nail on the head” and the elegant original is much preferred.  It’s used to mean “correctly identify something or exactly to arrive at the correct answer”.  Interestingly, the Oxford English Dictionary (OED) notes there is no documentary evidence that the phrase comes from “nail” in the sense of the ting hit by a hammer.

Double-headed nails are used for temporary structures like fencing.  When the shaft is hammered in to the point where the surface of the lower head is flat against the surface of that into which it's being hammered, it leaves the upper head standing proud with just enough of the shaft exposed to allow a claw-hammer to be used to extract nail.  There is a story that as part of an environmental protest against the building or demolition of some structure (the tales vary), activists early one morning went to the temporary fencing around the contested site and hammered in all the double-headed nails.  This is believed to be an urban myth.

The sense of “fingernail” appears to be the original which makes sense give there were fingernails before there were spikes (of metal or any other material) used to build stuff.  The verb nail was from the Old English næglian (to fix or fasten (something) onto (something else) with nails), from the Proto-Germanic ganaglijan (the source also of the Old Saxon neglian, the Old Norse negla, the Old High German negilen, the German nageln and the Gothic ganagljan (to nail), all developed from the root of the nouns.  The colloquial meaning “secure, succeed in catching or getting hold of (someone or something)” was in use by at least the 1760; hence (hence the law enforcement slang meaning “to effect an arrest”, noted since the 1930s.  The meaning “to succeed in hitting” dates from 1886 while the phrase “to nail down” (to fix in place with nails) was first recorded in the 1660s.

As a noun, “nail-biter” (worrisome or suspenseful event), perhaps surprisingly, seems not to have been in common use until 1999 an it’s applied to things from life-threatening situations to watching close sporting contests.  The idea of nail-biting as a sign of anxiety has been in various forms of literature since the 1570s, the noun nail-biting noted since 1805 and as a noun it was since the mid-nineteenth century applied to those individuals who “habitually or compulsively bit their fingernails” although this seems to have been purely literal rather than something figurative of a mental state.  Now, a “nail-biter” is one who is “habitually worried or apprehensive” and they’re often said to be “chewing the ends of their fingernails” and in political use, a “nail biter” is a criticism somewhat less cutting than “bed-wetter”.  The condition of compulsive nail-biting is the noun onychophagia, the construct being onycho- (a creation of the international scientific vocabulary), reflecting a New Latin combining form, from the Ancient Greek ὄνυξ (ónux) (claw, nail, hoof, talon) +‎ -phagia (eating, biting or swallowing), from the Ancient Greek -φαγία (-phagía).  A related form was -φαγος (-phagos) (eater), the suffix corresponding to φαγεῖν (phageîn) (to eat), the infinitive of ἔφαγον (éphagon) (I eat), which serves as aorist (essentially a compensator for sense-shifts) (for the defective verb ἐσθίω (esthíō) (I eat).  Bitter-tasting nail-polish is available for those who wish to cure themselves.  Nail-polish as a product dates from the 1880s and was originally literally a clear substance designed to give the finger or toe-nails a varnish like finish upon being buffed.  By 1884, it was being sold as “liquid nail varnish” including shads of black, pink and red although surviving depictions in art suggests men and women in various cultures have for thousands of years been coloring their nails.  Nail-files (small, flat, single-cut file for trimming the fingernails) seem first to have been sold in 1819 and nail-clippers (hand-tool used to trim the fingernails and toenails) in 1890.

The expression "nail down the lid" is a reference to the lid of a coffin (casket), the implication being one wants to make doubly certain anyone within can't possible "return from the dead".  The noun doornail (also door-nail) (large-headed nail used for studding batten doors for strength or ornament) emerged in the late fourteenth century and was often used of many large, thick nails with a large head, not necessarily those used only in doors.  The figurative expression “dead as a doornail” seems to be as old as the piece of hardware and use soon extended to “dumb as a doornail” and “deaf as a doornail).  The noun hangnail (also hang-nail) is a awful as it sounds and describes a “sore strip of partially detached flesh at the side of a nail of the finger or toe” and appears in seventeenth century texts although few etymologists appear to doubt it’s considerably older and probably a folk etymology and sense alteration of the Middle English agnail & angnail (corn on the foot), from the Old English agnail & angnail.  The origin is likely to have been literally the “painful spike” in the flesh when suffering the condition.  The first element was the Proto-Germanic ang- (compressed, hard, painful), from the primitive Indo-European root angh- (tight, painfully constricted, painful); the second the Old English nægl (spike), one of the influences on “nail”.  The noun hobnail was a “short, thick nail with a large head” which dates from the 1590s, the first element probably identical with hob (rounded peg or pin used as a mark or target in games (noted since the 1580s)) of unknown origin.  Because hobnails were hammered into the leather soles of heavy boots and shoes, “hobnail” came in the seventeenth century to be used of “a rustic person” though it was though less offensive than forms like “yokel”.

In the 1930s, the straight-8 became a favorite for manufacturers of luxury cars, attracted by its ease of manufacture (components and assembly-line tooling able to be shared with straight-sixes), the mechanical smoothness inherent in the layout and the ease of maintenance afforded by the long, narrow configuration.  However, the limitations were the relatively slow engine speeds imposed by the need to restrict the “crankshaft flex” and the height of the units, a product of the long strokes used to gain the required displacement.  By the 1950s, it was clear the future lay in big-bore, overhead valve V8s although the Mercedes-Benz engineers, unable to forget the glory days of the 1930s when the straight-eight W125s built for the Grand Prix circuits generated power and speed Formula One wouldn’t again see until the late 1970s, noted the relatively small 2.5 litre (153 cubic inch) displacement limit for 1954 and conjured up a quixotic final fling for the layout.  Used in both Formula One as the W196R and in sports car race as the W196S (better rememberd as the 300 SLR) the new 2.5 & 3.0 litre (183 cubic inch) straight-8s, unlike their pre-war predecessors, solved the issue of crankshaft flex by locating the power take-off at the centre, adding mechanical fuel-injection and a desmodromic valve train to make the things an exotic cocktail of ancient & modern.  Dominant during 1954-1955 in both Formula One & the Sports Car Championship, they were the last of the straight-8s.

Schematic of Buick “Nailhead” V8, 1953-1966.

Across the Atlantic, the US manufacturers also abandoned their straight-8s.  Buick introduced their overhead valve (OHV) V8 in 1953 but, being much wider than before, the new engine has to be slimmed somewhere to fit between the fenders; it would not be until later the platform was widened.  To achieve this, the engineers narrowed the cylinder heads, compelling both an conical (the so-called “pent-roof”) combustion chamber and an arrangement in which the sixteen valves pointed directly upwards on the intake side, something which not only demanded an unusual pushrod & rocker mechanism but also limited the size of the valves.  So, the valves had to be tall and narrow and, with some resemblance to nails, they picked up the nickname “nail valves”, morphing eventually to “nailhead” as a description of the whole engine.  The valve placement and angle certainly benefited the intake side but the geometry compromised the flow of exhaust gases which were compelled through their anyway small ports to make a turn of almost 180^o on their way to the tailpipe.

It wasn't the last time the head design of a Detroit V8 would be dictated by considerations of width.  When Chrysler in 1964 introduced the 273 cubic inch (4.5 litre) V8 as the first of its LA-Series (that would begat the later 318, 340 & 360 as well as the V10 made famous in the Dodge Viper), the most obvious visual difference from the earlier A-Series V8s was the noticeably smaller cylinder heads.  The A engines used as skew-type valve arrangement in which the exhaust valve was parallel to the bore with the intake valve tipped toward the intake manifold (the classic polyspherical chamber).  For the LA, Chrysler rendered all the valves tipped to the intake manifold and in-line (as viewed from the front), the industry’s standard approach to a wedge combustion chamber.  The reason for the change was that the decision had been taken to offer the compact Valiant with a V8 but it was a car which had been designed to accommodate only a straight-six and the wide-shouldered polyspheric head A-Series V8s simply wouldn’t fit.  So, essentially, wedge-heads were bolted atop the old A-Series block but the “L” in LA stood for light and the engineers wanted something genuinely lighter for the compact (in contemporary US terms) Valiant.  Accordingly, in addition to the reduced size of the heads and intake manifold, a new casting process was developed for the block (the biggest, heaviest part of an engine) which made possible thinner walls.

The nailhead wasn’t ideal for producing ultimate power but it did lend itself to prodigious low-end torque, something much appreciated by Buicks previous generation of buyers who has enjoyed the low-speed responsiveness of the famously smooth straight-8.  However, like everybody else, Buick hadn’t anticipated that as the 1950s unfolded, the industry would engage in a “power race”, something to which the free-breathing Cadillac and Chrysler’s Hemis were well-suited.  The somewhat strangulated Buick Nailhead was not at all suited and to gain power the engineers were compelled to add high-lift, long-duration camshafts which enabled the then magic 300 horsepower number to be achieved but at the expense of smoothness and tales of Buick buyers returning to the dealer to fix the “rumpity-rump” idle became legion.  Still, the Nailhead was robust, relatively light and offered what was then a generous displacement and the ever inventive hot-rod community soon worked out the path to power was to use forced induction and reverse the valve use, the supercharger blowing the fuel-air mix through the exhaust ports and the exhaust gases through the larger intake ports.  Thus the for a while Nailhead enjoyed a career as a niche player although the arrival in the mid 1950s of the much more tunable Chevrolet V8s ended the vogue for all but a few devotees who continued use well into the 1960s.  Buick acknowledged reality and, unusually, instead of following the industry trend and drawing attention to cubic inch displacement and horsepower, publicized their torque output, confusing some (though probably not Buick buyers who were a loyal crew).

Lockheed SR-71 Blackbird (1964-1999).

Not confused was the United States Air Force (USAF) which was much interested in power for its aircraft but also had a special need for torque on the tarmac and that briefly meant another small niche for the Nailhead.  The Lockheed SR-71 Blackbird (1964-1979) was a long-range, high-altitude supersonic (Mach 3+) aircraft used by the (USAF) for reconnaissance between 1966-1998 and by the National Aeronautics & Space Administration (NASA) for observation missions as late as 1999.  Something of a high-water mark among the extraordinary advances made in aeronautics and materials construction during the 1950s & 1960s, the SR-71 used the Pratt & Whitney J58 turbojet engine which used an innovative, secondary air-injection system to the afterburner, permitting additional thrust at high speed.  The SR-71 still holds a number of altitude and speed records and Lockheed’s SR-72, a hypersonic unmanned aerial vehicle (UAV) is said to be in an “advanced stage” of design and construction although whether any test flights will be conducted before 2030 remains unclear, the challenges of sustaining in the atmosphere velocities as high as Mach 6+ onerous given the heat generated.

At the time, the SR-71 was the most exotic aircraft on the planet but during testing and early in its career, to fly, it relied on a pair of even then technologically bankrupt Buick Nailhead V8s.  These were mounted in a towed cart and were effectively the turbojet’s starter motor, a concept developed in the 1930s as a work-around for the technology gap which emerged as aero-engines became too big to start by hand but no on-board electrical systems were available to trigger ignition.  The two Nailheads were connected by gears to a single, vertical drive shaft which ran the jet up to the critical speed at which ignition became self-sustaining.  The engineers chose the Nailheads after comparing them to other large displacement V8s, the aspect of the Buicks which most appealed being the torque generated at relatively low engine speeds, a characteristic ideal for driving an output shaft.  After the Nailhead was retired in 1966, later carts used Chevrolet big-block V8s but in 1969 a pneumatic start system was added to the infrastructure of the USAF bases from which the SR-71s most frequently operated, the sixteen-cylinder carts relegated to secondary bases the planes rarely used.

Pre 1000: From the Middle English mule, from the Anglo-Norman mule and the Old English mūl, both from the Latin mūlus, from the primitive Indo-European mukslós.   Related were the Middle Dutch mūle, the Old French mul (mule, hinny), the Late Latin muscellus (young he-mule), the Old East Slavic мъшкъ (mŭškŭ) (mule), the Phocian Ancient Greek  μυχλός (mukhlós) (he-ass) and the German Maul, Maultier & Maulesel, again derived from Latin.  It’s thought the Latin word was influenced by the Proto-Italic musklo- which is probably (along with the Ancient Greek myklos (pack-mule) and the Albanian mushk (mule)) a loan-word from one of the languages of Asia Minor.  The noun muleteer (mule driver) dates from the 1530s and was from the French muletier, from mulet (mule), a diminutive formation which in French displaced the Old French mul as the word for "mule".  The adjective mulish (possessing the characteristics imputed to the mule) is used of people thought obstinate rather than hard working; the word was in use by 1751 and the  alternative is mulelike (or mule-like), mulesque apparently either never created or not catching on. Mule is a noun & verb, mulishness & muleteer are nouns, mulishly is an adverb and mulish & mulelike are adjectives; the noun plural is mules. 

The mule became a popular pack animal because it was aid to "combine the strength of the horse with the endurance and surefootedness of the ass" and for centuries mules extensively have been bred to select for one characteristic or the other, those working mountainous trails a different beast from those on the plains.  To be zoologically correct, a mule is properly the offspring of a he-ass and a mare; that of a she-ass and a stallion is technically a hinny while a mule born of a horse and a she-ass is a burdon, a late fourteenth century creation based on the Latin burdonem.  Ordinarily, male mules incapable of procreation and commonly the word is applied allusively of hybrids and things of mixed nature.  The phrase "test mule" entered engineering (and later product development generally) in the 1920s to describe devices built for purposes of evaluation and thus expendable, a fate suffered no doubt by many an unfortunate. 

The mule's well-deserved reputation as a stellar beast of burden appears in the odd idiomatic form but it's the other traits which accounts for most popular use and perhaps surprisingly, given "stubborn as a mule" now appears in much greater frequency than "dumb as a mule" .  The meaning “stupid person” was noted by the 1470s, that of someone "obstinate or stubborn” not emerging until the eighteenth century although the latter use has endured and "working like a mule" proved an acceptable replacement when "working like an N-word" became proscribed.  There must have been some grounds for the beast picking up its reputation for obstinacy but there seems no evidence of the origin of that but it must sufficiently have been recognized to gain currency and become a proverbial descriptor of stubbornness.  A soul with such a tendency said to be "mulish"; within the family, Winston Churchill's (1875-1965; UK prime-minister 1940-1945 & 1951-1955) daughter Sarah (1914-1982) was nicknamed “the mule” (the English upper classes do like nick-names).  It seems likely the phrase "kick like a mule" was born of bitter experience although modern use is almost exclusively figurative, stronger forms of alcoholic drink commonly attracting the label.  It was formalized as the "Moscow Mule" (a cocktail made with vodka, ginger beer, and lime juice) although in the Western intelligence community that term was used also of traitors in the pay of the Soviet Union.  That use was probably modelled on "drug mule", underworld slang for "a smuggler of narcotics" which was noted as early as 1935 and came into general use in the post-war years.  The mule-deer of the western United States picked up the name because of its strikingly large ears.  

The so-named spinning machine dates from 1793 (first known as the "mule jenny" in 1788), the name derived from it being a "hybrid" of Richard Arkwright's (1732–1792) drawing-rollers and the spinning jenny invented by the English carpenter James Hargreaves (circa 1720–1778).  In what seems to have been an imaginative flight of etymological fancy, it was in the eighteenth century suggested the name "mule" was applied because the thing without complaint did so much of the labor which would otherwise have to be undertaken by human hand but there seems no doubt the inspiration was the machine's hybrid origin.  The use to describe the loose slipper worn as footwear was drawn into English in the 1560s from the Old French mule (slipper) from the Latin mulleus calceus (literally “red high-soled shoe”), a shoe worn by Roman patricians and associated with magistrates.  This footwear is unrelated to the long tradition of the Roman Catholic Pope wearing red shoes, the association tracing back to the notion of the blood of Christ falling on his feet as he carried on his back the cross on which he was crucified on Golgotha.  They were made again famous by fashion icon Benedict XVI (1927–2022; pope 2005-2013, pope emeritus 2013-2022) although his successor, Francis (b 1936; pope since 2013), favours plain black.

Mules, by definition are backless but may be sling-backs and can have open or closed toes.  There are many who would classify these as sandals and some manufacturers agree.  In this context "mule" was from the Ancient Roman mulleus calceus a red (or reddish-purple) shoe popular with upper-class Romans and worn as a symbol of office by the three highest magistrates although the scant historical evidence does suggest the Roman footwear looked more like modern clogs than mules and logically, one would expect footwear with thicker, tougher soles would at the time have been preferred for use outdoors.  High-heeled mules became a popular indoor style during the 1700s, influenced by the pattern, a backless overshoe of the sixteenth century, although, by early in the twentieth, mules were often derided as the "dress-wear" of the "better class of prostitutes" and it wasn’t until Marilyn Monroe (1926–1962) adopted the mule in the 1950s they again assumed some respectability.  By the 1990s, mules were among the most popular of shoes.

The descriptors mules, clogs and slides are sometimes used interchangeably.  The typical clog is a closed-toed wooden (or other) soled shoe with a heel no more than a couple of inches high.  Clogs are backless (although there are clog boots).  Mules, by comparison, traditionally had a higher heel although the strictness applied to that definition has weakened the emphasis seemingly now on the backlessness although there standards too are loose, slingback mules common.  The term slide derives from being applied to designs permitting the foot to slide in and may thus apply to both mules and clogs rather than being a distinct style.

Ossuary

Ossuary (pronounced osh-oo-er-ee or os-oo-er-ee)

(1) A structure dedicated to the storage of the bones of the dead.

(2) Any container for the burial of human bones, such as an urn.

(3) By extension, a place for discarded or broken items or (figuratively), of abandoned concepts or ideas. 

1650-1660: From the Late Latin ossuārium (charnel house; receptacle for bones of the dead), a neuter of ossuārius (of or for bones) and variant of ossārium, the construct being oss- (stem of os) (bone (plural ossua)) + -ārius (the adjectival suffix giving the sense “of or related to”).  The Latin os was from the primitive Indo-European ost (bone).  The model for the word was mortuarium, and the alternative form remains ossuarium.  Ossuary and ossuarium are nouns and ossuarius is an adjective; the noun plural is ossuaries.

The Sedlec Ossuary at Starosedlecká, Kutná Hora, in the Bohemian region of the Czech Republic lies about 42 miles (70 km) east of the capital, Prague.  A medieval town, much of the baroque architecture was build between the thirteenth and sixteenth centuries from the wealth generated by the adjacent silver mine.  On architectural grounds alone Kutná Hora is worthy of its status as a UNESCO World Heritage site but, in the suburb of Sedlec is the Church of All Saints which probably deserves a separate listing.

Sedlec’s Church of All Saints is better known as the Sedlec Ossuary, the church of bones, said to contain the bones of between some forty and sixty-thousand dead.  Its origins were a mission by the abbot of the Sedlec Cistercian Monastery, sent by the King of Bohemia to Jerusalem.  The abbot returned with an urn of soil from the Golgotha, the place where Jesus Christ was said to be crucified and this earth he spread around the grounds of the church’s cemetery.  As word of the "Holy Soil" became known, from all over Bohemia, people began to ask to be buried at Sedlec’s Church of All Saints.

Such was the demand that by the fifteenth century, skeletal remains had to be exhumed from the cemetery, the town needing to expand and more space needed for the more recently dead.  In what may sound a little shocking (but must have been judged theologically sound), the bones lay stacked in the basement of the church until 1870 when František Rint (1835-circa 1895), a woodcarver and carpenter from the small town of Česká Skalice in northern Bohemia, was employed by the House of Schwarzenberg (the ruling family of the town) to organize and arrange them.  The results of his efforts were spectacular, the carpenter creating intricate sculptures, including several chandeliers and a copy of the Schwarzenberg coat of arms.  The most spectacular of the chandeliers is also technically interesting for anatomists, said to include at least one of every bone in the human body

The elaborate constructions may seem macabre but each is accompanied by religious displays arranged from bone, conveying to visitors the message that the chapel remains a respectful place of worship and indeed, regular masses continue to be held in both the upper and lower chapel.  Musical performances however are staged only within the church proper so what might prove the interesting acoustic properties of all those bones remains unexplored.  The site, opened to tourists early in the century proved popular, almost a quarter-million visiting in the last year before the pandemic and it quickly became the biggest attraction in central Bohemia.  The financial blessing has proved also a curse however, local residents complaining the volume of visitors often overwhelms the operations of what remains a functioning Roman Catholic church and cemetery.  It’s said there are tourists who treat the place as just another theme-park.

Still, such is the importance of the ossuary to the local economy, that the ancient site is often renovated, including some attention to the condition of the bones which sounds strange but it seems human bone is subject to discoloration over time and restoring them to a more brilliant white is thought greatly to enhance the tourists' visual experience.  Even if one’s taste doesn’t extend to the macabre, Kutná Hora remains one of the medieval treasures of Bohemia and within the same Cistercian complex as the ossuary is the Sedlec Cathedral, the Church of the Assumption of Our Lady and Saint John the Baptist.  Built between 1290-1320, the cathedral is one of the oldest remaining in the Baroque Gothic style and also enjoys a place on the UNESCO World Heritage list and a short distance from there is a truly secular attraction, the Kutná Hora's Chocolate Museum, a tiny homage to chocolate with exhibits dating from the early nineteenth century.  There are chocolate tasting sessions and private candlelit dinners can be booked.

The ossuary vibe: Lindsay Lohan wearing Alexander McQueen skull scarf, 2012.

So entrenched in fashion has the skull been for hundreds of years that not even its use (as the “Death’s Head”) by the Nazi SS (the Schutzstaffel (security squad), 1925-1945, also stylized as ᛋᛋ with Armanen runes) tainted it sufficiently to discourage its appearance on clothes, accessories and jewelry.  Seasonally, the popularity ebbs and flows but skulls are seemingly always at least a niche and the appeal is also cross-cultural, the skull variously a good luck charm and a symbol employed to ward of disease and evil spirits.  In the English-speaking world, the widespread use of the skull symbol seems to have begun in the Elizabethan period (1558-1603) although most acknowledge the practice began in Bohemia and came to England via sea-farers and traders, the original items being skull rings, either carved from a human jawbone or rendered from metal.  An especially popular form was the skull ring with the jawbone disappearing to create the illusion of a finger piercing the wearer's mouth, still a widely used pattern today.  One curious aspect of the appeal is that Satanists and Christians alike have both embraced the iconography, skulls a likely to be seen among Devil worshipers as they are to be in the mix with images of saints and crucifixes.  Of late though, while they haven’t disowned the medieval art, Christianity seems now less keen on skulls.  The Satanists remain committed.
