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

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

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

1969 Rolls-Royce Silver Shadow.

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

1967 Rolls-Royce Silver Shadow two-door saloon by James Young (left) and 1971 two door saloon by Mulliner Park Ward (MPW) (right).

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

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

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

Shadow Volumes

Example of shadow mapping with Python summarized by FinFET.

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

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

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

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

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

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

The Microsoft Volume Shadow Copy Service (VSS)

The handy Nirsoft Utilities includes a Shadow Copy viewer.

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

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

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

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

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

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

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

Umbra

Umbra (pronounced uhm-bruh)

(1) Shade; shadow, now restricted mostly to literary use.

(2) The invariable or characteristic accompaniment or companion of a person or thing.

(3) In astronomy, the complete or perfect shadow of an opaque body, as a planet, where the direct light from the source of illumination is completely cut off.

(4) In astronomy, the dark central portion of a sunspot.

(5) A phantom or shadowy apparition, as of someone or something not physically present; ghost; spectral image.

(6) An uninvited guest brought along by one who was invited (archaic).

(7) The fully shaded inner region of a shadow cast by an opaque object.

(8) One of the family Umbridae of mudminnows; a sciaenoid fish, the umbrine.

(9) In typography, a sans-serif display typeface released in 1935 as a variation of the earlier Tempo.  Similar to many contemporary art deco designs, it's constructed with a shadow effect, the letter shapes built as negative space and defined by a black dimensional shadow.

1590s: From the Latin umbra (literally “shade”; shadow), a doublet of umber and of uncertain origin.  If it was from the Old Latin omra, source may have been the primitive Indo-European hzmrup-, related to the Ancient Greek ἀμαυρός (amaurós) (dark) and “rot” & “rotten” in the Luwian hieroglyphic.  Etymologists also note the Hittite Maraššantiya (their name for the Kızılırmak River), and this Indo-European source is said to be a possible borrowing from a Semitic root ḥ-m-r (be red), linked to the Arabic ح م ر‎ (ḥ m r).  All agree there is a connection with the Lithuanian unksna.  The adjectives are umbral & umbrageous and the noun plurals are umbras & umbrae.

The early meaning was that of a “phantom or ghost," a figurative use drawn from the Latin umbra (shade, shadow), which gave rise to the later umbrage (A feeling of anger or annoyance caused by something offensive or (now rarely) a feeling of doubt, from the Middle French ombrage (umbrage), from the Old French ombrage, from the Latin umbrāticus (in the shade), from umbra (shadow, shade)).  The astronomical sense of a "shadow cast by the earth or moon during an eclipse" was first used during the 1670s.  The meaning "an uninvited guest accompanying an invited one" is from 1690s and was an invention in English, from a secondary sense used in Ancient Rome.  The related noun umber (brown earthy pigment) is from the 1560s, from the French ombre (in terre d'ombre), or the Italian ombra (in terra di ombra), both from the Latin umbra (shade, shadow) or otherwise from Umbra, the feminine form of Umber "of or belonging to Umbria, the region in central Italy from where the coloring material was first discovered.  Burnt umber, specially prepared and redder in color, is attested from circa 1650 and distinguished from raw umber, both well-known to artists of the era.

It’s the cosmic coincidence of the relationship between the diameter of the Moon and its distance from the Sun which makes solar eclipses such a spectacular sight from planet earth.  On other planets, where the relationship is different, solar eclipses may not be as enchanting.  A solar eclipse happens sometimes as the Moon moves between the Sun and Earth, the Moon blocking the light of the Sun from reaching Earth.  Astronomers classify solar eclipses into three types:

(1) A total solar eclipse which is visible from a small area on Earth.  Those who see a total eclipse are those standing in the center of the Moon's shadow when it hits Earth. The sky becomes very dark, as if it were night. A total eclipse occurs only when the Sun, Moon and Earth are in a direct line.

(2) A partial solar eclipse happens when the Sun, Moon and Earth are not exactly aligned, the sun appearing to have a dark shadow on a small part of its surface.

(3) In an annular solar eclipse, the Moon seems further because the annular happens when the Moon is farthest from Earth and thus does not block the entire view of the Sun, instead looking like a dark disk on top of a larger Sun-colored disk.

A solar total eclipse.

Solar eclipses are not rare, visible around every eighteen months somewhere on Earth although the viewing spot is always relatively small.  Unlike lunar eclipses, solar eclipses last only a few minutes.  The umbra is the darkest part of a shadow, especially the cone-shaped region of full shadow cast by Earth, the Moon, or another body during an eclipse. In a full lunar eclipse, which generally lasts for one or two hours, the entire disk of the Moon is darkened as it passes through the umbra. During this period the Moon takes on a faint reddish glow due to illumination by a small amount of sunlight that is refracted through the Earth's atmosphere and bent toward the darkened Moon; the reddish tint is caused by the filtering out of blue wavelengths as the sunlight passes through the Earth's atmosphere, leaving only the longer wavelengths on the red end of the spectrum.

The umbra is the innermost and darkest part of a shadow, the area in which the light source is entirely obscured by the occluding body and if standing in this space, the viewer will experience a total eclipse.  Viewed in the abstract, the Sun, Moon & Earth all being (almost) spherical, umbra forms a right circular cone and, if viewed from the cone's apex, the two bodies will seem the same size.  The penumbra, from the Latin paene (almost, nearly) is the region in which only some of the light source is obscured by the occluding body so the viewer standing in the experiences a partial eclipse.  The antumbra, from the Latin ante (before) is the region from which the occluding body appears entirely within the disc of the light source.  The viewer standing in this apace experiences an annular eclipse, which manifests as a bright ring visible around the eclipsing body.  If the viewer is able to move closer to the light source, the apparent size of the occluding body increases until it causes a full umbra.

An umbraphile (shadow lover) is a person with much interest in eclipses, often making extraordinary efforts to travel to see them.  The construct is umbra +‎ phile.  Phile is from the Latin -phila, from the Ancient Greek φίλος (phílos) (dear, beloved) and from the same source is -phil, a word-forming element meaning "one that loves, likes, or is attracted to," via the French -phile and the Medieval Latin -philus in this sense, from the Ancient Greek -philos, a common suffix in personal names (such as Theophilos), from philos (loving, friendly, dear; related, own) and related to philein (to love) which is of unknown origin.  One authoritative etymologist suggests the original meaning was "own; accompanying" rather than "beloved."

Umbraphilia emerged as a niche in nineteenth century high-end tourism, gentlemen scientists and society figures sailing around the world to observe and sometimes report their findings.  The longest known observation of a solar eclipse was that undertaken on 30 June 1973 when a group travelled on board the Concorde, enjoying seventy-four minutes of totality.

Wraith

Wraith (pronounced reyth)

(1) The apparition of a person living (or thought to be alive), said to appear as a portent of impending death.

(2) A visible spirit; a ghost or any apparition.

(3) In art or graphic design, a a deliberately insubstantial (sometimes even translucent) copy or representation of something.

(4) Something pale, thin and lacking in substance (a column of smoke; swirling mist etc).

1510s: A word of uncertain etymology.  Some trace it back to an Old English from the Old Norse reith or reidh (twisted or angry) and in Old English it evolved into wrethe (used generally to refer to “anger, fury or vengeance”).  As Middle English emerged it shifted to wraith which came to be associated with “a ghost or spirit, especially one thought to be the spirit of one dead or about to die”.  The link between the earlier meanings of anger and the later association with spirits may reflect the origins of the modern idea of “a restless or vengeful spirit”.  Most however prefer a connection with early sixteenth century Middle Scots, some suggesting it was from a translation of the Aeneid (29-19 BC), the epic poem written by the Roman poet Virgil (Publius Vergilius Maro (70–19 BC)) which recounts the legend of Aeneas, a Trojan who fled the fall of Troy to travelled to Italy, where he became the ancestor of the Romans.  That view has limited support although many etymologist do seem to agree it was in Middle Scots the form was first popularized, probably as warth, word meaning something like or related to “ghost”, the word perhaps from the Old Norse vorðr (“watcher or guardian” (in the sense of “guardian angel”), source of the Icelandic vörður (guard) and which may also have been an influence on the Gaelic & Irish arrach (specter, apparition)."  Wraith & wrathfulness are nouns, wraithlike, wraithesque, wraithful & wraithish are adjectives and wrathfully is an adverb; the noun plural is wraiths.

A wraith-like Lindsay Lohan, Las Angeles, 2008.  In art or graphic design, a wraith is a deliberately insubstantial (sometimes even translucent) copy or representation of something.  It’s used also of something or someone pale and thin, especially in reaction to sudden or considerable weight-loss.

More speculative is the idea of any link with the Middle English wray or bewray and few are convinced any exist despite the similarity in form (something anyway hardly unusual in English).  Even the origin of wray is contested although the orthodox history contends it was from the Middle English wrayen, wraien & wreien (to show, make known, accuse), from the Old English wrēġan (to urge, incite, stir up, accuse, impeach), from the Proto-Germanic wrōgijaną (to tell; tell on; announce; accuse), from the primitive Indo-European were- or wrē- (to tell; speak; shout).  It was said to be akin to the Dutch wroegen (to blame), the German rügen (to reprove) and the Swedish röja (to betray; reveal; expose).  Beray was from the Middle English bewraien, bewreyen & biwreyen, from the Old English bewrēġan, from the Proto-Germanic biwrōgijaną (to speak about; tell on; inform of), the construct being be- +‎ wray.  It was cognate with the Old Frisian biwrōgja (to disclose, reveal), the Dutch bewroegen (to blame; accuse), the Middle Low German bewrȫgen (to accuse; complain about; punish), the Old High German biruogen (to disclose, reveal) and the Modern German berügen (to defraud).  The attraction of the idea of a relationship between wray or beray and wraith is the use of wraith to mean a “vengeful” spirit.

JRR Tolkien (1892–1973), a philologist (is the study of language in oral and written historical sources) of some note, favored a link with writhe on the basis of the sense of “writhing; bodily distorted” (as in a ghost or apparition).  Writhe was from the Middle English writhen, from the Old English wrīþan, from the Proto-West Germanic wrīþan, from the Proto-Germanic wrīþaną (to weave, twist, turn), from the primitive Indo-European wreyt- (to twist, writhe).  It was cognate with the Middle Dutch writen (to turn, twist), the dialectal German reiden (to turn; twist around), the Danish vride (to twist), the Swedish vrida (to turn, twist, wind) and the French rider (to wrinkle, furrow, ruffle).

Not quite what she meant: Gretchen Wieners (Lacey Chabert (b 1982)) in Mean Girls (2004).

In late eighteenth century English, the noun “fetch” could mean “apparition of a living person, specter, a double”, from fetch-life (a deity, spirit, etc who guides the soul of a dead person to the afterlife (a psychopomp)) the source an English dialect word of unknown origin but which may have been from the Old English fæcce (evil spirit formerly thought to sit on the chest of a sleeping person; a mare) and may have been related to or even from the Old Irish fáith (seer, soothsayer).  The (now archaic) "fetch candle" was a mysterious light, which, when seen at night, was believed to foretell a person's death.  The Irish idea of the fetch and the fetch light describes the apparition associated with impending death (commonly in English now called a wraith).  The fetch or wraith was a doppelganger (double) of the dying who appeared when the time was approaching for them to need their spirit to guide them to the afterworld (ie act as a psychopomp).  The poet Percy Bysshe Shelley (1792–1822) and the writer Goethe (Johann Wolfgang von Goethe, 1749–1832) are among those who described seeing their own wraiths although most are said to have been visible only to those surrounding the dying.

1952 Rolls-Royce Silver Wraith with touring limousine coachwork by Park Ward.

Rolls-Royce has for almost a century used model names which summon imagery of the silently ethereal including Ghost, Phantom, Seraph, Shadow, Spirit, Spectre & Wraith.  The first Wraiths were introduced in 1938 and although World War II (1939-1945) interrupted things, almost 500 chassis left the factory between then and 1946.  The name was revived in 1946 when the company introduced their first post-war model as the Silver Wraith and although stylistically there would be nothing like the imaginative lines of the new US cars, the underpinnings were significantly modernized and the model would remain in the catalogue until 1958 with almost 2000 chassis produced.  Unlike the smaller Silver Dawn (1949-1955), the factory would only ever supply the Wraith rolling chassis to coachbuilders who would fabricate the bodies in accordance with customer preference although, the (slightly) higher-performance Bentley version was available with what came to be known as the “standard steel body”.

1971 Rolls-Royce Silver Shadow long-wheelbase (LWB) saloon with central division (top) and 1979 Rolls-Royce Silver Wraith (bottom).

Within two years of the introduction of the Silver Shadow (1965-1980), a long-wheelbase (“LWB” which gained an additional 4 inches (100 mm) odd of rear-seat leg room) version had been produced and this configuration was introduced as a factory option in most markets between 1969-1971.  Built sometimes with an electrically operated glass division (the associated hardware absorbing most of the gained rear legroom) production continued on a small scale until 1976 when the Silver Shadow II was released at which point the LWB was re-branded as the Sliver Wraith II, incorporating not only the Shadow’s worthwhile mechanical improvements (which was good) but also carrying-over the vinyl roof (which was bad).  Rolls-Royce always used a brand of high-quality vinyl called “Everflex” and never used the word “vinyl”.  The re-naming followed the practice adopted in 1971 when the Silver Shadow two-door saloon (1966-1971) and convertible (1967-1971 and then known as a Drophead Coupé (DHC)) was renamed Corniche which, in convertible form would last until 1995, the saloon retired in 1980.

2015 Rolls-Royce Wraith.  The “Starlight headliner” was fabricated by weaving some 1300 strands of fibre-optic cable into the ceiling’s leather lining.  In the US market the option listed at US$14,700, a cost which reflected the high labor component in the production process and it should be compared with the bespoke audio system option which cost US$8,625 (the bulk of the input costs of the audio system was in mass-produced solid-state components).  Rolls-Royce has confirmed the 2023 Wraiths will be their last V12 coupés, the replacement (electric) Spectre going on sale in 2024. 

When introduced in 2013, it was the first time since 1946 the word “Wraith” had been used by the factory as a stand-alone model name.  Only ever available as a two door hardtop (no central pillar) coupé, the Wraith used the highly regarded 6.6 litre (402 cubic inch), twin-turbocharged BMW V12 used in their flagship 7 Series (G11 2015-2022) in happier times.  As is the modern practice at Rolls-Royce, a number of limited production runs of special models were available in the decade the Wraith was made but the platform also attracted the tuners, some emphasizing addition power, some additional stuff, all with high-price tags.

Mansory’s original version of the Rolls-Royce Wraith (top) was almost restrained, something later abandoned when the “Palm Edition 999” (bottom) was released.

German-based Mansory modifies high-priced cars, boosting both power and bling.  A particular specialty is carbon-fibre fabrication, the standard of their work acknowledged as world class and their approach to engineering is also sound, something not always achieved by those who make already highly tuned engines more powerful still.  The appearance (inside & out) of the machinery they modify doesn’t suit all tastes but their success proves a market exists for such things and their sales in markets like the Middle East and India proves that east of Suez there’s a receptive (and rich) audience.  Things from Rolls-Royce, Ferrari etc are anyway expensive but for Mansory (an others) the target market is not millionaires but billionaires, some of the latter needing accessories to prove they’re not merely one of the former.  Just to make sure the message was getting through however, when Rolls-Royce released their SUV (sports utility vehicle), Mansory badged their take as the Rolls-Royce Cullinan Mansory Billionaire (the project a co-development with the German fashion house Billionaire).  Disappointingly perhaps, it was advertised with a list price well under US$1 million.  In the long-running cartoon show The Simpsons, nuclear power-plant co-owner C Montgomery Burns used the phrase “price taggery” in one sense but it's applied also when discussing Veblen goods produced for the "conspicuous consumption" market; there, the purpose of the product is to advertise one's disposable income and a well-publicized (high) price-tag is essential.  

The electric Rolls-Royce Spectre.  Instead of an internal combustion engine, the Spectre is powered by two electric motors producing a combined net 577 horsepower and 664 pound-feet of torque.  There was a time when Rolls-Royce would never have painted their cars purple but the catchment of those with the resources to buy or lease (rent) such things has expanded to include many whose tastes come from different traditions.  It's not the difference between good and bad taste; it's just a difference.

Rolls-Royce has announced its intention by 2030 to offer a range of vehicles powered exclusively by electric propulsion.  For Rolls-Royce, the engineering and financial challenges aside, the obstacles are few because, unlike an operation like Ferrari which for decades has based part of its mystique on the noise its engines make at full-cry, it has always put a premium of silence and smoothness.  Enzo Ferrari (1898-1988) said it was the howl of the V12 Packard engines (which he dubbed “the song of 12”) he heard on the race tracks which convinced him to make the V12 the signature configuration for the cars which would bear his name but for Charles Rolls (1877–1910), the co-founder of Rolls-Royce, the most influential sound was its absence.  In 1904, he had the opportunity to ride in Columbia Electric car and, knowing what so many of his customers craved, was most impressed, noting: “The electric car is perfectly noiseless and clean. There is no smell or vibration. They should become very useful when fixed charging stations can be arranged.”  So, in 120-odd years not much has changed.  Ferrari are doubtlessly hoping the hydrogen re-fueling infrastructure develops at a similarly helpful rate, the exhaust note from exploding hydrogen able to be as intoxicating as that of burning hydrocarbons.

(1) A sometimes highly embroidered, broad-brimmed hat of straw or plush felt, usually with a high conical or cylindrical crown and a saucer-shaped brim, worn especially in Spain, Mexico, and the south-western United States.

(2) A style of automobile wheel-cover which became popular in the US during the 1950s, the enveloping design vaguely similar to the motifs associated with the hat.

(3) A mixed drink, made with coffee liqueur and cream.

(4) In ten-pin bowling, a series of four consecutive strikes.

1590–1600: From the Spanish from sombrero de sol (broad-brimmed hat offering shade from the sun) and originally "umbrella, parasol" (a sense found in English by the 1590s), from sombra (shadow; shade) from the Late Latin subumbrare (to shadow), the construct being sub (under) + umbrāre (from umbra (shadow)) + ero (the dative & ablative singular of erus, from the Proto-Italic ezos (master), from the primitive Indo-European heshós (master) and cognate with the Hittite išhāš (master)) and thus literally "shade-maker".  Sombrero is a noun and sombreroed is an adjective, (the non-standard sombrerolike & sombreroesque both used informally); the noun plural is sombreros.

Politicians are often compelled to wear sombreros in the search for votes.  Others wear them by choice.

Traces of a sombrero-like shape can be discerned in the designs used for the early post-war Cadillacs but it was in the 1950s the style became popular with many manufacturers emulating the lines.  Although less popular by the early 1960s, the coachbuilders Hess & Eisenhardt chose to use sombrero-style wheel covers from the 1957 Lincoln Premiere when the White House’s 1961 presidential parade limousine was updated in 1963 with a current model grill.  This was the famous SS X-100 (the Secret Service inventory number) in which the president was assassinated in Dallas in November 1963.  It was extensively re-modeled in the aftermath of the assassination (and again in 1967), Hess & Eisenhardt reverted to the turbine-style wheel covers from the Continental Mark II (1956-1957) with which the car had originally been fitted.  Although other presidential parade cars were built in 1968 and 1972, X-100 continued to be used by Presidents Johnson, Nixon, Ford and Carter until 1977 and it’s now on permanent display in the Henry Ford Museum in Dearborn, Michigan.

The terms “wheel cover” & “hubcap” (or hub-cap) have long been used interchangeably but the two, historically, are different.  The distinction between the two is that a wheel cover covers the entire diameter of the wheel whereas a hubcap covers only the center portion of the wheel, concealing at most only the lug nuts which secure the wheel.  The origin of the hub cap pre-dates powered-transportation and was simply a device which fitted over the hub of a wheel to prevent dirt and debris from entering the assembly and contaminating the grease which provided lubrication and some of the early versions were actually called dirt-caps or grease-caps.

As wheel designs evolved from those used on hand-carts or horse-drawn vehicles, the hubcaps were enlarged to extend protection to the lug nuts, reducing abrasion and limiting the moisture penetration which encouraged rust.  The hubcap was thus a purely utilitarian device and this functionality was extended in the 1920s when all-enveloping wheel covers (some of which had actually been seen in the nineteenth century) began to appear in volume.  These were usually covers for wire wheels (a type preferred because they were much lighter that those made from pressed steel) and served to protect both the spokes and the brakes behind from dirt and the impact of stones and rocks, an important consideration when so many roads were un-sealed.  Owners and drivers appreciated the protection, wire wheels notoriously time-consuming to clean.  One drawback however was that the air-flow to the brake drums was inhibited so the brakes were more prone to overheating, thus reducing their retardative effect but as some soon discovered, speed and economy were actually improved because the smooth wheel covers were aerodynamically more efficient, as aspect of design which continues to be exploited to this day.  In the UK, both hubcaps and wheel covers were originally called nave plates.  Nave (hub of a wheel) was from the Middle English nave, from the Old English nafu, from the Proto-West Germanic nabu, from the Proto-Germanic nabō (which influenced the Dutch naaf, the German Nabe and the Swedish nav), from the primitive Indo-European hneb- (navel) and related to the Latin umbō (shield boss), the Latvian naba and the Sanskrit नभ्य (nabhya).  The idea of it being “something central” was a development from the Latin nāvem, the singular accusative of nāvis, terms from architecture which referred to the middle section of a church (later extended to other structures & shipbuilding).

Also exploited, for better and worse, were aesthetic sensibilities.  It was in the stylistically exuberant US of the 1950s that wheel covers became truly extravagant and heavy, the latter something that brought its own problems.  The design teams took to wheel covers with enthusiasm because changes were cheap to implement and they soon became part of product differentiation, the higher in the hierarchy a model sat, the more elaborate the wheel covers were likely to be.  The sombreros were just one style, others referencing influences as diverse as the original wire wheels, the turbines in jet engines, water fountains, the full moon (though without pock-marks) and beehives.

Wheel covers became part of what was typically an annual cycle of styling changes and it wasn’t unusual for those used on last year’s top-of-the-line model to re-appear on a cheaper line and just because wheel covers had arrived, hubcaps didn’t go away, fitted almost always as standard equipment on the cheapest entry-level models and those defined as heavy-duty such as the ones built for police fleets.  Simple steel stampings, they were cheap to produce and, being lightweight, were less prone to becoming detached during brisk driving, the “flying hubcap” (actually usually a wheel cover) a noted feature of many of Hollywood’s car chases and something the many film buffs delight in noting sometime escape the "continuity process", a lost wheel cover inexplicably having re-attached itself later in the sequence.  The simple pressings were sometimes dubbed “poverty hubcaps” but a more common nickname was “dog dish”, a reference to their appearance if upturned.

The wheel cover as part of a re-style was not restricted to the US but manufacturers in the UK & Europe were more conservative (an exception to this tended to be the locally produced models from companies ultimately owned by US corporations; as in Australia, these sometimes used hand-me-downs from Detroit), hubcaps persisting longer while “trim-rings” began to be added to emulate wheel covers but designs were often carried over from one model to the next.  In this, the Mercedes-Benz 600 (M100, 1963-1981) is a footnote in hubcap history in that in its eighteen-odd years in production, the only styling change (other than the disfigurements demanded by US regulators) was to replace the two-piece hubcap/trim ring combination with a one-piece wheel cover.  This was unfortunate because the earlier style better suited the car and designers have distinguished between them, calling one the "frowning" and the other the smiling, the 600 definitely a "frowning" sort of car.

Wheel covers remained of interest to those designing cars for competition, the trade-off between brake cooling and aerodynamic advantage weighed up according to the nature of the event.  On the circuits a premium usually was attached to cooling but those setting speed records were particularly attracted to the smoothest possible shape which meant flat wheel covers of some description were often fitted and where possible many choose to enclose the wheel to whatever extent was possible; In testing, Jaguar discovered an additional 3-4 mph (5-6 km/h) could be attained if the XK120’s (1948-1954) rear wheels were wholly enclosed by fender skirts (also called spats).  In the modern era, even with aluminum or composite wheels optimized for lightness and brake cooling, there are manufacturers which use additional wheel covers, either to produce downforce for use in competition or to reduce drag, lowering energy consumption to increase a vehicle’s range.  Like many manufacturers of EVs (electric vehicles) Tesla uses the combination of aluminium wheels (for weight-saving) and a plastic wheel cover (for aerodynamic efficiency), the latter the main reason why there have been so few EV convertibles, the inherent inefficiency of the shape imposing a significant penalty "in the drag".  When the naked wheel of a Tesla Cybertruck is revealed, many are struck by the attractiveness of the design.

The selfie sombrero, a 2014 co-development between Christian Cowan-Sanluis and Acer Inc of Taiwan.

In 2014, in one of the IT industry’s less remembered collaborations with the fashion business, designer Christian Cowan-Sanluis (b 1994) joined with Taiwanese (Taiwan a renegade province of the People’s Republic of China (PRC)) manufacturer Acer to produce a “limited-edition” (a perhaps unnecessary announcement) sombrero with an integrated tablet, able to spin through 360^o.  Said to be the ultimate solution to selfie takers who struggle to find their best angle, the wide-brimmed apparatus included an Iconia A1-840 tablet.  Listed upon release at a not unreasonable Stg£599, the selfie-sombrero was based on a hat in Cowan-Sanluis' autumn-winter 2014 collection, noted for having been modeled by Lady Gaga (b 1986).

Technically, the design was helpful for selfie-takers because of the mounting which allowed the tablet to spin through 360^o, helping the user to determine the best angle while snapping and reviewing the results.  With an internet connection, the perfect selfie could then instantly be uploaded to the social platform of choice.  Early adopters were encouraged to place an order, the designer noting the creation of ten pink sparkly glitter cases with accompanying hats in the same style as that worn by Lady Gaga.
