1350-1400: From the Middle English noun bobel which may have been from the Middle Dutch bubbel & bobbel and/or the Low German bubbel (bubble) and Middle Low German verb bubbele, all thought to be of echoic origin.  The related forms include the Swedish bubbla (bubble), the Danish boble (bubble) and the Dutch bobble.  The use to describe markets, inflated in value by speculation widely beyond any relationship to their intrinsic value, dates from the South Sea Bubble (a classic example of stock-price speculation) which began circa 1711 and collapsed in 1720.  In response to the collapse, the UK parliament passed The Bubble Act (1720), which required anyone seeking to float a joint-stock company to first secure a royal charter; interestingly, the act was supported by the South Sea Company before its failure.  Ever since cryptocurrencies emerged, analysts have been describing them as a bubble which will burst and while that has happened with hundreds of coins (the exchange collapses are something different), the industry thus far has continued with only with occasional periods of inflation and deflation; this makes cryptocurrencies highly volatile meaning there is much scope for profit and much risk of loss, the extent to which they're subject to insider trading an manipulation has been debated but only as a matter of degree.  Bubble & bubbling are nouns & verbs, bubbler is a noun, bubbled is a verb, bubbly is a noun & adjective, bubbleless & bubblelike are adjectives and bubblingly is an adverb; the noun plural is bubbles.

Tulips.  The collective noun police in the seventeenth century missed an opportunity in not declaring that henceforth the standard use would be: "a bubble of tulips".

However, although the South Sea affair was the first use of “bubble” to describe such a market condition, it wasn’t the first instance of a bubble, the most infamous of which was the Dutch tulpenmanie (tulip mania) which bounced during the 1630s, contract prices for some bulbs of the recently introduced and wildly fashionable flower reaching extraordinarily high levels, the values accelerating from 1634 until a sudden collapse in 1637.  Apparently just a thing explained by a classic supply and demand curve, the tulip bubble burst with the first big harvest which demonstrated the bulbs and flowers were really quite common and easy to grow.  In history, there would previously have been many bubbles but it wasn’t until the economies and financial systems of early-modern Europe were operating that the technical conditions existed for them to manifest in the form and to the extent we now understand.  Interestingly, for something often regarded as the proto-speculative asset bubble and a landmark in economic history, twentieth-century revisionist historians have suggested it was more a behavioral phenomenon than anything with any great influence on the operation of financial markets or the real economy, the “economic golden age” of the Dutch Republic apparently continuing (mostly) unaffected for almost a century after the bottom fell out of the tulip market.  The figurative uses have been created or emerged as required, the first reference pre-dating the tulip affair, the usual motion being andything lacking a desired firmness, substance, or permanence; the first recorded used was in the 1590s but it was likely long established in oral use.  The soap-bubble dates from 1800, bubble-shell is from 1847, bubble-gum was introduced in 1935 and bubble-bath appears first to have be sold in 1937.  The slang noun variation “bubbly” was first noted in 1920, an invention of US English to describe a happy, talkative young lady.

The term "bubble top" (also briefly as "bubble-top") came into use in the 1940s after advances in materials and manufacturing techniques allowed the cockpit canopies of aircraft to be made using large Perspex moldings.  The concept had been around for decades but it was the combination of modern plastics and the demands of wartime which made possible the mass-production of large moldings.  The designers called them "bubble canopies" but pilots preferred the snappier "bubbletop".  Spitfire TE288 was built in May 1945 at Vickers Armstrong's Castle Bromwich factory but, with the end of hostilities in Europe it was only briefly in service, mostly in a training role.  Gifted in 1964 to the Canterbury branch of the Brevet Club, it was mounted on a plinth as a memorial outside the club's building but by 1984 had become so valuable it was moved to the RNZAF (Royal New Zealand Air Force) museum at Wigram.  During restoration, molds were taken and a fibreglass replica was constructed to be placed on the plinth.  Optimized for the low-altitude performance needed to counter the threat of the German V1 “Doodlebugs” (an early cruise missile), the Spitfire Mk XVI was a variant of the Mark IX and powered by the Packard-built Rolls-Royce Merlin 266 engine rated 1,720 HP (horsepower).  Entering production in October 1944, 1,054 were built and as well as serving as interceptors, they were used in the ground attack role, notably against the sites from which the V2 missiles (an early ballistic missile and the first major step on the path to ICBMs (inter-continental ballistic missile) and the big rockets used by the US in the Apollo programme) were launched.  The bubble canopy afforded outstanding visibility while the clipped wingtips improved responsiveness (notably the superior roll-rate) while sacrificing some performance above 15,000 feet (4,500 metres) but by then the demands of aerial combat had shifted lower in the sky.

1961 Pontiac Ventura Sports Coupe (Bubble Top).

The term (as bubble top) later was applied to cars with rooflines in a shape which recalled the use in aviation although the structures were of conventional metal & glass.  The classic examples were the full-sized two-door hardtops produced by GM's (General Motors) Chevrolet and Pontiac divisions in 1960-1962, the 1961 models the most collectable.  The 1961 Pontiac Ventura Sports Coupe (a sub-model of the Catalina) pictured is fitted with Pontiac's much admired 8-Lug wheels, their exposed centres actually the brake drum to which the rim (in the true sense of the word) directly was bolted.  Introduced for 1960, the design was a fortuitous conjunction of fashion & function because as well as looking good, the heat dissipation qualities were outstanding, addressing one of the problems which plagued drum brakes.  Unfortunately, the design was not compatible with (outboard) disc brakes and as their fitment increased, sales of the option (circa US$125) fell and in 1968 production of the 8-Lug ceased.  

The word "bubble" spiked shortly after the start of the Covid-19 pandemic.  Over time, use has expanded to encompass large-scale operations like touring sporting teams and even the geographical spaces used for the 2022 Beijing Winter Olympics but the original meaning was more modest: small groups based on close friends, an extended family or co-workers.  These small bubbles weren't supposed to be too elastic and operated in conjunction with other limits imposed in various jurisdictions; a bubble might consist of a dozen people but a local authority might limit gatherings to ten in the one physical space so two could miss out, depending on the details in the local rules.  The way most governments handled the pandemic was a bit muddled but in such events, as in most wars, much is a muddle.  Bubble thus began as an an unofficial term used to describe the cluster of people beyond one's household with whom one felt comfortable in an age of what was believed a highly infectious virus.  Bubbles were however a means of risk-reduction, not a form of quarantine.  In a bubble, risk still exist, most obviously because some may belong to more than one bubble, contact thus having a multiplier effect, the greater the number of interactions, the greater the odds of infection so staying home and limiting physical contact with others remained preferable, the next best thing to an imposed quarantine.  The more rigorously administered bubbles used for events like the Olympics are essentially exercises in perimeter control, a defined "clean" area, entry into which is restricted to those tested and found uninfected.  At the scale of something like an Olympic games, it's a massive undertaking to secure the edges but, given sufficient resource allocation can be done although it's probably misleading to speak of such an operation as as a "bubble".  Done with the static-spaces of Olympic venues, they're really quarantine-zones.  Bubble more correctly describes touring sporting teams which move as isolated bubbles often through unregulated space.

The Bubble Skirt

A type of short skirt with a balloon style silhouette, the bubble dress (more accurately described as a bubble skirt because that’s the bit to which the description applies) is characterized by a voluminous skirt with the hem folded back on itself to create a “bubble” effect at the hemline.  Within the industry, it was initially called a tulip skirt, apparently because of an at least vague resemblance to the flower but the public preferred bubble.  It shouldn’t be confused with the modern tulip skirt and the tulip-bubble thing is just a linguistic coincidence; there’s no link with the Dutch tulipmania of the 1630s.  Stylistically, the bubble design is a borrowing from the nineteenth century bouffant gown which featured a silhouette made of a wide, full skirt resembling a hoop skirt, sometimes with a hoop or petticoat beneath to provide structural support.  While bouffant gowns could be tea (mid-calf) or floor length, bubble skirts tend to truncate the look well above the knee; while calf-length creations are seen in collects, they're rare on the high street.  Perhaps with a little more geometric accuracy, the design is known also as the “puffball” and, in an allusion to oriental imagery, the “harem” skirt.  Fashion designer Christian Lacroix (b 1951) became fond of the look and a variation included in his debut collection was dubbed le pouf but, in English, the idea of the “poof skirt” never caught on although it was used by furniture makers.

It must have been a memorable sight in the still austere post-war world, a sheath dress made voluminous with layers of organza or tulle, the result a cocoon-like dress with which Pierre Cardin (1922-2022) and Hubert de Givenchy (1927-2018) experimented in 1954 and 1958, respectively. A year later, Yves Saint Laurent (1936-2008) for Dior added the combination of a dropped waist dress and bubble skirt; post-modernism had arrived.  For dressmakers, bubble fashion presented a structural challenge and mass-production became economically feasible only because of advances in material engineering, newly available plastics able to be molded in a way that made possible the unique inner construction and iconic drape of the fabric.  For that effect to work, bubble skirts must be made with a soft, pliable fabric and the catwalk originals were constructed from silk, as are many of the high end articles available today but mass-market copies are usually rendered from cotton, polyester knits, satin or taffeta.

The bubble skirt was never a staple of the shows in the sense that it would be missing from annual or seasonal collections, sometimes for a decade or more and sales were never high, hardly surprising given it was not often a flattering look for women above a certain age (perhaps anyone aged over eight or nine).  Deconstructing the style hints at why: a hemline which loops around and comes back up (created sometimes by including a tighter bottom half with the bulk of additional material above), it formed a shape not dissimilar to a pillow midway through losing its stuffing.  For that reason, models caution the look works best when combined with a sleek, fitted top to emphasize the slimness of the waistline, cinched if necessary with a tie or belt of some sort to delineate when one thing starts and the other finishes.  The bubble needs to be the feature too, avoiding details or accessories which might otherwise distract; if one appears to be wearing a partially un-stuffed pillow, the point needs to be made it’s being done on purpose and the obvious way that's achieved is to ensure it's the focus piece.  Really, tempting though it may seem in the catalogue, it's a style for experts in a narrow BMI (body mass index) range.

On the catwalks however, again seemingly every decade or so, the bubble returns, the industry relying on the short attention span of consumers of pop culture inducing a collective amnesia which allows many resuscitations in tailoring to seem vaguely original or at least a novel variation on the theme.  Still, if ever a good case could be made for a take on a whimsical 1950s creation to re-appear, it was the staging of the first shows of the 2020-2021 post-pandemic world and the houses responded, Louis Vuitton, Erdem, Simone Rocha and JW Anderson all with billowy offerings; even seen was an improbably exuberant flourish of volume from Burberry.  What appeared on the post-Covid catwalk seemed less disciplined than the post-war originals, the precise constraints of intricately stitched tulle forsaken to encourage rather more swish and flow, the look romantic rather than decadent.  Generally the reception was polite but for those who hoped for a more adventurous interpretation, history suggests the bubble will be back in a dozen-odd years.

Strapless, pale-pink bubble gown (Look 53) from Balenciaga's Spring/Summer 2026 collection, Paris Fashion Week, October 2025.

By using a structural bubble hem, the gown illustrates how a light-weight fabric can be made to emulate a selective rigidity.  The fashion critics said the oversized glasses were there as an evocation of futurism but the skinnytokers (said to be “the acceptable pro ana”) call it the “bug-eye look” and recommend them because the exaggerated size of the frames and lens creates the visual illusion of making the face appear thinner.  Most catwalk models are of course anyway splendidly slender but skinnytok's skinnysplainers would suggest they’d look good even on them; in such matters, the skinnytokers are the world's foremost experts.  The double-faced fabric was neo gazar (the original gazar a silk organza with a plain weave created by the house in 1957-1958), co-developed by Balenciaga and the textile company Lorma, incorporating a soft silk & wool lamiset weft.  The advantages neo gazar offers are said to be a capacity to maintain a shape without the same extent of internal framework, while being easier to work with than original, more rigid, silk gazar.

Although Look 53 may be a classic case study of the disconnect between what appears on catwalks in headline collections and stuff actually sold, that’s not a criticism because such pieces must be assessed on the basis of fulfilling their intended purpose and that this creation admirably did.  Pierpaolo Piccioli’s (b 1967) first collection for the house (after a long stint at Valentino) was much anticipated by critics, most of whom appear to have been impressed, noting the designer’s mastery handling of the distinctive “house codes” Balenciaga has over the decades made signatures.  So everybody liked the clothes but whether the show notes were of much help is uncertain, notably the text: “The meaning of Balenciaga is a methodology.  The process of creation as ideology, as identity, an expression of humanity and human invention.”  The collection deserved to be judged on its merits but what to make of the show notes?  It was grammatically coherent English and so laden with words and phrases with recognizable semantic associations that, in a strictly linguistic sense, the passage couldn’t be devoid of meaning but what would be concluded by those not students of textual deconstruction?  It was of course a delight for those students because it was an exemplar of what in literary theory is called “semantic inflation” (or “floating signifiers”), abstract nouns arranged in a way that might be used by sentences saying something profound while yielding no precise meaning.  Structurally, what each phrase did was substitute a metaphorical association for a concrete predication; nothing could be proved or falsified.

Walmart Mission and Vision Statement: No background in literary deconstruction required.

Just about every process of course has a “method” with “methodology” used just as a “fancy” way of making what seems an obvious point and while the process of creation certainly can be an expression of an ideology, something more specific in the text may have helped.  After all, what people create is by definition “an expression of humanity and human invention”, that applying equally to bubble dresses, hamburgers and nuclear weapons.  Still, while not as succinct a statement as something like E=mc², the show notes were not useless because earnest students of marketing effortlessly would identify the ritualistic, atmospheric prose as part of the discourse of luxury branding which needs to convey characteristics such as “edginess”, “avant-garde sensibility”, “intellectual seriousness” and a certain distance from the vulgar business of selling cheap clothes to the working class shopping at places like Walmart.  Between themselves, in expressions, gestures, clothing and more, the rich often communicate in intricate or elaborate codes not obvious to others.  Positioning the company in the cultural & economic milieu of those used to abstractions, Balenciaga would be assured the folk who buy their garments could (unlike the literalists at price-tag-focused Walmart), interpret connotative meaning despite the absence of denotative precision, the trick being to read not what is said but what is meant.  Indeed, so impressed might some of them have been by the show notes they may even have “sampled” chunks of the text for their next mission statement because it’s hard to improve on: “Recollection rather than tribute, shadows of Balenciaga’s architectonic shapes are embedded in the actuality of today—bold and disruptive volumes applied to clothes that define our modern wardrobe.  A vocabulary of contemporaneity, entirely transformed through approach.”

Bubbletop

Bubbletop (pronounced buhb-uhl-top)

(1) In aircraft design, a design of pilot’s canopy (originally military slang for what designers dubbed the “bubble canopy”, a Perspex molding which afforded exceptional outward visibility).

(2) An automobile using a transparent structure over the passenger compartment, replacing the usual combination of roof & windows.

(3) A descriptor of certain automobiles (as "Bubble Top") of the early 1960s, based on the shape rather than the method of construction, conventional metal and glass used.

1940s: The construct was bubble +‎ top.  Bubble dates from the late fourteenth century and was from the Middle English noun bobel which may have been from the Middle Dutch bubbel & bobbel and/or the Low German bubbel (bubble) and Middle Low German verb bubbele, all thought to be of echoic origin.  The related forms include the Swedish bubbla (bubble), the Danish boble (bubble) and the Dutch bobble.  Top pre-dates 1000 and was from the Middle English top, toppe & tope (top, highest part; summit; crest; tassel, tuft; (spinning) top, ball; a tuft or ball at the highest point of anything), and the Old English top & toppa (top, summit, tuft of hair), from the Proto-West Germanic topp, from the Proto-Germanic tuppaz (braid, pigtail, end), of unknown origin.  It was cognate with the Old Norse toppr (top), the Scots tap (top), the North Frisian top, tap & tup (top), the Saterland Frisian Top (top), the West Frisian top (top), the Dutch top (top, summit, peak), the Low German Topp (top), the German Zopf (braid, pigtail, plait, top), the Swedish topp (top, peak, summit, tip) and the Icelandic toppur (top).  Alternative forms are common; bubble-top in automotive & aeronautical engineering and bubble top in fashion.  Bubbletop is a noun and bubbletopped is an adjective; the noun plural is bubbletops.

Evolution of the Mustang's bubbletop: P-51C (top), P-51 III (centre) and P-51D (bottom).

“Bubbletop” began as World War II (1939-1945) era military slang for officially was described as the “bubble canopy”, the transparent structure sitting atop the cockpit of fighter aircraft, the advantages being (1) superior visibility (the purest interpretation of the design affording an unobstructed, 360° field-of-view, (2) improved aerodynamics, (3) easier cockpit ingress & egress (of some significance to pilots force to parachute and (4), weight reduction (in some cases).  Bubbletops had been seen on drawing boards in the early days of aviation and some were built during World War I (1914-1918) but it was the advent of Perspex and the development of industrial techniques suitable for the creation of large, variably-curved moldings which made mass-production practical.  The best known early implementations were those added to existing air-frames including the Supermarine Spitfire, Republic P-47 Thunderbolt and North American P-51 Mustang.  By 1943, the concept had become the default choice for fighter aircraft and the technology was applied also to similar apparatuses used elsewhere on the fuselage where they were styled usually as “blisters”.  In the post war years it extended to other types, most dramatically in the Bell 47 helicopter where the cabin was almost spherical, some 70% of the structure clear Perspex.

The enormous and rapid advances in wartime aeronautics profoundly influenced designers in many fields and nowhere was that more obvious than in the cars which began to appear in the US during the 1950s.  Elements drawn variously from aeronautics and ballistics did appear in the first generation of genuinely new post-war models (most of what was offered between 1945-1948 being barely revised versions of the 1942 lines) but it was in the next decade the designers were able to embrace the jet-age (a phrase which before it referred to the mass-market jet-airline travel made possible by the Boeing 707 (which entered commercial service in 1958) was an allusion to military aircraft, machines which during the Cold War were a frequent sight in popular culture).  On motif the designers couldn’t resist was the bubble canopy, something which never caught on in mass-production although Perspex roofed cars were briefly offered before word of their unsuitability for use in direct sunlight became legion.

GM Firebird XP-21 (Firebird I, 1953).

Not content with borrowing the odd element from aircraft, the General Motors (GM) team decided the best way to test which concepts were adaptable from sky to road was to “put wheels on a jet aircraft” and although they didn’t do that literally, by 1953 when Firebird XP-21 was first displayed, it certainly looked as though it was exactly that.  Its other novelty was it was powered by a gas turbine engine, the first time a major manufacturer in the US had built such a thing although a number of inventors had produced their own one-offs.  When the XP-21 (re-named Firebird I for the show circuit) made its debut, some in the press referred to it as a “prototype” but GM never envisaged it as the basis for a production car, being impractical for any purpose other than component-testing; it should thus be thought of as a “test-bed”.  The bubble canopy looked as if it could have come from a US Air Force (UFAF) fighter jet and would have contributed to the aerodynamically efficiency, the 370 hp (280 kW), fibreglass-bodied Firebird I said to be capable of achieving 200 mph (320 km/h) although it’s believed this number came from slide-rule calculations and was never tested.  Despite that, in its day the Firebird II made quite a splash and a depiction of it sits atop the trophy (named after the car’s designer, Harley Earl (1893–1969), the long time head of GM’s styling studio) presented each year to the winner of NASCAR’s (National Association for Stock Car Auto Racing) premiere event, the Daytona 500.

GM Firebird II (1956).

Compared with its predecessor, the Firebird II (1956), rendered this time in titanium was almost restrained, the Perspex canopy a multi-part structure over a passenger compartment designed to seat “a family of four”.  The family might have chosen to drive mostly in darkness because the heat build-up under the midday sun would have tested the “individually-controlled air conditioning”, a system upon which comfort depended because the Perspex sections were fixed; there were no opening “windows”.  Still, even if hot, the family would have got places fast because the same 200 mph capability was claimed.

GM Firebird III (1958).

The Firebird III was displayed at the 1958 Motorama and although GM never built any car quite like it, within a season, elements of it did begin to appear on regular production models in showrooms (notably the rear skegs which Cadillac used for a couple of years) and some of its features are today standard equipment in even quite modest vehicles.  The striking “double bubbletop” never made the assembly lines although some race cars have at least partially implemented the concept.  What proved more of a harbinger was the specification, the Firebird III fitted with anti-lock brakes, cruise control, air conditioning, an automated “accident avoidance system” and instead of a steering wheel, the driver controlled the thing with a joystick, installed in a centrally-mounted “Unicontrol & Instrument Panel”.  All these were analogue-era electro-mechanical devices too bulky, fragile or expensive for mass production, wider adoption in the decades to come made possible by integrated circuits (IC) and micro-processors.

1959 Cadillac Cyclone (XP-74).

Borrowing from the Firebird II, Cadillac also used a bubble top for the Cyclone (XP-74) concept car which in 1959 toured the show circuit.  Although it was powered by the corporation’s standard 390 cubic inch (6.5 litre) V8, there was some adventurous engineering including a rear-mounted automatic transaxle and independent rear suspension (using swing axles, something not as bad as it sounds given the grip of tyres at the time) but few dwelt long on such things, their attention grabbed by features such as the bubble top (this time silver coated for UV (ultra violet) protection) which opened automatically in conjunction with the electrically operated sliding doors.  The Perspex bubble canopies from fighter aircraft never caught on for road or race cars but so aerodynamically efficient was the shape it found several niches.

1953 Ferrari F166MM Spider by Vignale (left) and 1969 MGCGT (centre) and the MGC's replica hood in  fibreglass (right).

Bubbles often appeared atop the hood (bonnet) to provide clearance for components inconveniently tall (typically induction systems).  Most were centrally located (there was the occasional symmetrical pair) but the when BMH (British Motor Holdings, the old  BMC (British Motor Corporation) shoehorned their big, heavy straight-six into the MGB (1963-1980), it wouldn’t fit under the bonnet, the problem not the cylinder head but the tall radiator so the usual solution of a “bonnet bulge” was used.  However, for that to clear the forward carburetor, the bulge would have been absurdly high so a small bubble (usually, ones this size are referred to as "blisters") was added.  It probably annoyed some there wasn’t a matching (fake) one on the other side but it’s part of the MGC’s charm, a quality which for years most found elusive although it’s now more appreciated.  For MGC owners wish to shed some weight or for MGB owners who like the look, the “bonnet with bubble” is now available in fibreglass.

The winning Ford GT40 Mark IV (J-Car) with bubble to the right, Le Mans 1967 (left) and the after-market (for replicas) “Gurney Bubble” (right).

US racing driver Dan Gurney (1931–2018) stood 6' 4" (1.9 m) tall which could be accommodated in most sports cars and certainly on Formula One but when he came to drive the Ford GT40 Mark IV it was found he simply didn’t fit when wearing his crash helmet.  The original GT40 (1964) gained its name from the height being 40 inches (1016 mm) but Mark IV (the “J-Car”, 1966) was lower still at 39.4 inches (1,000 mm).  Gurney was the tallest ever to drive the GT40 and the solution sounds brutish but fix was effected elegantly, a “bubble added to the roof to clear the helmet.  Gurney and AJ Foyt (b 1935) drove the GT40 to victory in the 1967 Le Mans 24-hour endurance classic and the protrusion clearly didn’t compromise straight-line speed, the pair clocked at 213 mph (343 km’h), on the famous 3.6-mile Mulsanne Straight (which was a uninterrupted 3.6 miles (5.8 km) until the Fédération Internationale de l'Automobile (the FIA; the International Automobile Federation and world sport’s dopiest regulatory body) imposed two “chicanes”),  Known ever since as the “Gurney Bubble”, such is the appeal that they’re now available for any GT40 replica: Like the AC Shelby Cobra, the GT40 “reproduction” industry is active and there are many times more of these than there are survivors of 105 originals.

Ferrari 250 GT “Tour de France” LWB Berlinettas by Zagato: The “double bubble” roof (left), the Hofmeister kink (centre) and the famous “Z” kink, (right).

The Italian coachbuilding house Zagato was founded in 1919 by Ugo Zagato (1890-1968) and since the early post-war years, their designs have sometimes been polarizing (the phrase “acquired taste” sometimes seen), their angularity often contrasted with the lines of other, notably Pinninfarina and Bertone but unlike many which have over the years folded, Zagato remains active still.  One Zagato design never criticized was his run in 1956 of five Ferrari 250 GT “Tour de France” LWB Berlinettas, memorable also for introducing the signature “Zagato double-bubble roof.  The roof was practical in that it better accommodated taller occupants but it really was a visual trick and a variation on the trick Mercedes-Benz used on the “Pagoda” (W113; 230, 250 & 280 SL; 1963-1971) which they explained by saying “We didn’t lower the roof, we rained the windows”.  The other famous feature (which appeared on only one) was the fetching “Z” shape on the rear pillar, replacing the “Hofmeister kink” used on some others.

1962 Chevrolet Impala “bubble top” Sport Coupe (left), 1963 Ford Consul Capri (centre) and 1972 BMW 3.0CS (E9, right).

The 1959 Chevrolet quickly came to be nicknamed “bubble top” and the style spread, both within GM and beyond.  The “bubble top” reference was to the canopy on aircraft like the P-51D Mustang but was an allusion to the shape, not the materials used; on cars things were done in traditional glass and metal.  Across the Atlantic, Ford in the UK applied the idea to their Consul Capri (1961-1964), a two-door hardtop which the company wanted to be thought of as a “co-respondent's” car (ie the sort of rakish design which would appeal to the sort of chap who slept with other men’s wives, later to be named as “co-respondent” in divorce proceedings).  The Capri was a marketplace failure and the styling was at the time much criticized but it’s now valued as a period piece.  Chevrolet abandoned the look on the full-size cars after 1963 but it was revived for the second series Corvair (1965-1969).  A fine implementation was achieved in the roofline of the BMW E9 (1968-1975) which remains the company’s finest hour.

The bubble shirt and bubble tops.

The bubble skirt (worn by Lindsay Lohan (centre)) is one of those garments which seems never to quite die, although there are many who wish it would.  Once (or for an unfortunate generation, twice) every fashion cycle (typically 10-12 years), the industry does one of its "pushes" and bubble skirts show up in the high street, encouraged sometimes by the odd catwalk appearance; it will happen again.  While the dreaded bubble skirt is easily identifiable, the “bubble top” is less defined but there seem to be two variations: (1) a top with a “bubble skirt-like” appendage gathering unhappily just above the hips (left) and (2) a kind of “boob tube” which, instead of being tightly fitted is topped with an additional layer of material, loosely gathered.  The advantages of the latter (which may be thought of as a “boob bubble”) are it can (1) without any additional devices create the illusion of a fuller bust and (2) allow a strapless bra to be worn, something visually difficult with most boob tubes because the underwear’s outline is obvious under the tight material.

Bulla

Bulla (pronounced bool-uh or buhl-uh)

Circa 1845: From the Latin bulla (round swelling, stud, boss, knob (literally “bubble”)), either from the Latin Latin bullire (to boil), or from the Gaulish, from the primitive Indo-European bew- or beu- (a swelling) or bhel- (to blow, inflate, swell) which may have formed a large group of words meaning “much, great, many” (and also words associated with swelling, bumps, blisters and such and the source also of the Lithuanian bulė "buttocks and the Middle Dutch puyl (bag); etymologists remain divided over any link with the Latin bucca (cheek).  In medieval times, it referred to the seal (or stamp) attached to official documents because of its rounded, blister-like shape, familiar from many uses.  The speculative link with the Latin bullire (to boil) was an allusion to the need for heat to be applied to melt or partially melt the material (gold, lead, wax etc) used in the making of seals (once thus softened, the impression was applied).  Historically, while wax seals wear the most common, official imperial seals were gold and papal seals of lead (although some were gold).  The use to describe certain documents issued by the papal chancellery is an adoption of Medieval Latin.  Although it was never an absolute rule (the seal with a representation of the saints Peter and Paul on one side and the name of the reigning pope on the other has appeared variously), its existence usually indicates a papal document is a bulla, a specific type of papal document distinguished by its formality, purpose, and its authentication.  Bulla is a noun; the noun plural is bullas (the Latin bullae used of the papal documents).

Bulls begin with the phrase Episcopus Servus Servorum Dei (The Bishop, Servant of the Servants of God) and are written in a formal style.  The significance of a document being a bull is that technically it is a decree with enduring legal & doctrinal authority including ex cathedra pronouncements or administrative acts (which can be as procedural as creating religious orders or dioceses).  In this they differ from (1) encyclicals which are letters intended for broader purposes, addressed to bishops, clergy, and the faithful, often dealing with theological or social issues, (2) Apostolic Constitutions which usually deal with issues of governance, the promulgation of liturgical texts or matters pursuant to earlier bullae and (3) Motu Proprio (literally “on his own initiative”) which are edicts issued personally by the pope and these can be used for just about any purpose although they’re most associated with rulings which provide an “instant solution” to a troublesome or controversial matter on which it’s not been possible to find consensus; the Moto Proprio may thus be compared to a "royal decree".  Papal bulls were more common in the medieval and early modern periods when formal seals were the primary means of authentication but today they are rare, most communication from the Vatican in the form of apostolic letters or exhortations, not all with origins in the papal chancellery.

The last papal resignation but one

Even when absolute monarchies were more common, kings usually took care to placate at least elite opinion and today, although the constitutional arrangements in Saudi Arabia, Brunei, Oman and Eswatini (the old Swaziland) remain, on paper, absolute monarchies, even there things are not done quite as once they were.  The Holy See remains an absolute monarchy and is now the only theocracy so structured although doubtlessly many popes have lamented their authority seems to exist more in the minds of canon lawyers than among the curia or his flock, something exacerbated now malcontents can no longer be burned at the stake (as far as is known) and Francis (b 1936; pope since 2013) may recall the words of a world-weary Benedict XIV (1675–1758; pope 1740-1758): “The pope commands, his cardinals do not obey, and the people do what they wish.”

Papal Bull issued by Urban VIII (1568–1644; pope 1623-1644).  By the mid-fifteenth century, papal bulls had ceased to be used for general public communications and were restricted to the more formal or solemn matters.  The papal lead seals (the spellings bulla & bolla both used) were attached to the vellum document by cords made of hemp or silk, looped through slits.

But popes still have great powers not subject to checks & balances or constitutional review, the best known of which is “papal infallibility”.  The Roman Catholic Church’s dogma of papal infallibility holds that a pope’s rulings on matters of faith and doctrine are infallibility correct and cannot be questioned and when making such statements, a pope is said to be speaking ex cathedra (literally “from the chair” (of the Apostle St Peter, the first pope)).  Although ex cathedra pronouncements had been issued since medieval times, as a point of canon law, the doctrine was codified first at the First Ecumenical Council of the Vatican (Vatican I; 1869–1870) in the document Pastor aeternus (shepherd forever).  Since Vatican I, the only ex cathedra decree has been Munificentissimus Deus (The most bountiful God), issued by Pius XII (1876–1958; pope 1939-1958) in 1950, in which was declared the dogma of the Assumption; that the Virgin Mary "having completed the course of her earthly life, was assumed body and soul into heavenly glory".  Pius XII never made explicit whether the assumption preceded or followed earthly death, a point no pope has since discussed although it would seem of some theological significance.  Prior to the solemn definition of 1870, there had been decrees issued ex cathedra.  In Ineffabilis Deus (Ineffable God (1854)), Pius IX (1792–1878; pope 1846-1878) defined the dogma of the Immaculate Conception of the Blessed Virgin Mary, an important point because of the theological necessity of Christ being born free of sin, a notion built upon by later theologians as the perpetual virginity of Mary.  It asserts that Mary "always a virgin, before, during and after the birth of Jesus Christ", explaining the biblical references to brothers of Jesus either as children of Joseph from a previous marriage, cousins of Jesus, or just folk closely associated with the Holy Family.

Technically, papal infallibility may have been invoked only the once since codification but since the early post-war years, pontiffs have found ways to achieve the same effect, John Paul II (1920–2005; pope 1978-2005) & Benedict XVI (1927–2022; pope 2005-2013, pope emeritus 2013-2022) both adept at using what was in effect a personal decree a power available to one who sits at the apex of what is in constitutional terms an absolute theocracy.  Critics have called this phenomenon "creeping infallibility" and its intellectual underpinnings own much to the tireless efforts of Benedict XVI while he was head of the Inquisition (by then called the Congregation for the Doctrine of the Faith (CDF) and now renamed the Dicastery for the Doctrine of the Faith (DDF)) during the late twentieth century (the Holy See probably doesn't care but DDF is also the acronym, inter alia, for “drug & disease free” and (in gaming) “Doom definition file” and there's also the DDF Network which is an aggregator of pornography content).  So while not since 1950 formally invoked, popes have not been reluctant to “play the de facto infallibility card”, possibly thinking of the (probably apocryphal) remark attributed to John XXIII (1881-1963; pope 1958-1963): “When one is infallible, one has to be careful what one says.”

Bulla issued 17 July 1492 by Innocent VIII (1432–1492; pope 1484-1492) granting St Duthac’s Church (Tain) official permission to become a Collegiate Church.

But for a pope’s own purposes, a bulla can prove invaluable.  Pietro Angellerio (1215-1296) was for five months between July and December 1294 installed as Pope Celestine V.  Prior to his elevation, Celestine had for decades been a monk and hermit, living a anchorite existence in remote caves and subsisting on little more that wild vegetables, fruits, honey and the occasional locust, his unworldly background meaning he emerged as the ultimate compromise candidate, declared pope after a two-year deadlock in the church’s last non-conclave papal election.  The cardinals had been squabbling for all those two years which so upset the hermit in his cave that he wrote them a letter warning divine retribution would be visited upon them if they didn't soon elect a pope.  Realizing he was entirely un-political, without enemies and likely pliable, the cardinals promptly elected him by acclamation.

Shocked, the hermit declined the appointment, only to have his own arguments turned on him, the cardinals insisting if he refused the office he would be defying God himself; trapped, he was crowned at Santa Maria di Collemaggio in Aquila, taking the name Celestine V.  The anchorite, lost in the world of power politics and low skulduggery was utterly unsuited to the role and within weeks expressed the wish to abdicate and return to his solitary cave in the Abruzzi Mountains.  The cardinals told him it wasn’t possible and only God could release him from the office (will all that implies) but they couldn’t stop him consulting the lawyers who drafted for him two bulls, the first codifying the regulations concerning a pope’s abdication and the second a sort of “enabling act”.  The second bull (Quia in futurum (for in the future)) restored the constitution (Ubi periculum (Where there lies danger)), and re-established the papal conclave (the constitution had been suspended by Adrian V (circa 1216-1276; pope 1276)).  The bulls having put in place the required mechanisms, while at Naples, Celestine V abdicated.

That done, he resigned, intending to return to his cave but his successor, Boniface VIII (circa 1231-1303; pope 1294-1303) had no wish to have such a puritanical loose cannon at large (he feared some dissidents might proclaim him antipope) and imprisoned him (in an agreeable circumstances) in the castle where ultimately he would die.   His resignation from the office was the last until Benedict XVI who in 2013 did rather better, retiring to a sort of papal granny flat in the Vatican where he lived (uniquely) as pope emeritus.  Celestine was canonized on 5 May 1313 by Clement V (circa 1265-1314; pope 1305-1314) and no subsequent pontiff has taken the name Celestine. 

1966 Lamborghini Miura P400 re-painted in what most would probably call hot pink but professionals list as fashion fuchsia (Hex: #F400A1; RGB: 244, 0, 161; CMYK: 0, 100, 34, 4).  The Miura (1966-1973) was named after a breed of fighting bull and was the first Lamborghini to borrow an identity from bullfighting and the first to wear the corporate logo featuring a bull.  In the film The Italian Job (1969), a Miura is shown being crushed by a bulldozer but that was filmic trickery using a second, pre-wrecked car and the orange Miura seen driven through the Alps still exists.  In many places the film's car is referred to as "tangerine" or "orange", both of which well describe the vivid hue which the factory listed as Arancio Miura (meaning "Miura Orange" although the use in Italian of arancio to mean the color "orange" is untypical, the word used usually in the sense of "orange tree").  In a technological quirk, some film sites call the car "red" but that's a function of some prints or photographs not correctly maintaining the integrity or the original.  The term “hot pink” (Hex: #FF69B4; RGB: 255, 105, 180; CMYK: 0, 59, 29, 0) is used very loosely and has become the general term for bright shades while “baby pink” is used casually of most pastels.  In theory, the color palette is infinitely variable but the practical limitation is the range able to be perceived by the human eye, illustrated by the announcement in April, 2025 of the “discovery” of a “new color” (“new” in the sense no human had ever seen it although it may well be common around the universe).

To this day Lamborghini still uses terms from the tradition of bullfighting for some models which perhaps is surprising given bullfighting is now not as socially respectable as it was during the 1960s but disapprobation of the “sport” is not new and Pius V (1504–1572; pope 1566-1572) as early as 1567 called the practice: “alien from Christian piety and charity”, “better suited to demons rather than men” and “public slaughter and butchery” fit for paganism but not Christendom.  Word nerds will be delighted to note Pius V’s ban on bullfighting was technically a “papal bull”.  De Salute Gregis Dominici (On the Salvation of the Lord’s Flock) was issued on 1 November 1, 1567 as a formal proclamation with the papal lead bulla attached and, as an official decree, it was binding upon Church and Christian princes.  Appalled by the cruelty, Pius called bullfighting “a sin” and condemned the events as “spectacles of the devil”, prohibiting Christians from attending or participating under pain of excommunication.  However, like many papal thought bubbles down the ages which never quite make it to the status of doctrine, his ban was soon ignored and after his death the edict quietly was allowed to lapse.  Predictably, in Spain and Portugal, where bullfighting had deep cultural & political roots, the bulla was either ignored or resisted and Philip II (1527–1598; King of Spain 1556-1598), while as devout a Catholic as any man, was known as Felipe el Prudente (Philip the Prudent) for a reason and quietly he turned the royal blind eye, allowing bullfighting to continue.
