Oculus

Oculus (pronounced ok-yuh-luhs)

(1) In anatomy, an eye.

(2) In architecture, a window or other circular (or oval) opening, especially one at the apex of a dome.

(3) In archaeology, a design representing an eye, as on funerary pottery found in megalithic tombs of Europe.

(4) In the mechanical engineering (associated with fluid dynamics), the central boss of a volute.

(5) In poetic and literary use, luminary of the sun and stars; eye of the soul, mind's eye; a spot resembling an eye, such as on a peacock feather; a principle ornament or the main feature of something.

(6) In botany, a bud, bulb or knob on many roots, on the reed etc.

(7) As oculist (plural oculists), one who practices the discipline of oculism (an archaic name for an ophthalmologist or optometrist).

1857: From the Latin oculus (an eye), from the Proto-Italic okwelos, from the primitive Indo-European hsokw (eye; to see).  It was cognate with the Sanskrit अक्षि (ákṣi), the Ancient Greek ὄσσε (ósse), the Gothic augō, the Old English ēaġe (from which Modern English would gain eye) & the Proto-Slavic oko.  Originating in antiquity, it was a widely used feature of Byzantine and Neoclassical architecture, known in French as the œil de boeuf (bull's-eye).  The noun plural is oculi.  An impressively long word with the same root is ocularpneumoplethysmography, a non-invasive technique for detecting carotid stenosis by measurement of ophthalmic artery pressure.  Oculus & oculist are nouns; the noun plural is oculi (under the standard rules of English plural formations, the result would be oculuses by that seems to have been too awful to contemplate). 

The Pantheon

The Pantheon in Rome (from the Latin Pantheum, from the Ancient Greek Πάνθειον (Pantheion) ([temple] of all the gods) was built as a Roman temple and since the 609 has been a Roman Catholic church (Basilica di Santa Maria ad Martyres or Basilica of Saint Mary and the Martyrs).  It was built on the site of an earlier temple constructed during the time of Christ and rebuilt by the Emperor Hadrian circa 126 AD, the actual date uncertain because Hadrian retained the old inscriptions.

Cylindrical with a portico of sixteen staggered Corinthian columns, the dome has a diameter of 43.2m (142 feet) and was for over 1300 years the largest in the world and remains, after some two-thousand years, the largest unreinforced concrete dome, a feat achieved by a gradual reduction in the thickness and weight of the materials used for the upper layers.  Each of the granite columns weigh sixty tons.  Quarried in Egypt, they were dragged 100 km (60 miles), placed on barges and shipped up the Nile to Alexandria where they were transferred to boats to cross the Mediterranean to the port of Ostia.  From there, they were sent by barges, up the Tiber to Rome where they were dragged to the construction site for erection.

The dome was originally covered in bronze and there are reports from travelers of it sparkling in the sunlight, the glint playing on the surrounding skyline.  However during the middle ages most was pilfered, sometimes with official sanction, sometimes not, the shortage of building materials often acute.  The last of it, Pope Urban VIII (Maffeo Barberini, 1568–1644, pope 1623-1644) in 1631, needing ordinance for his military campaigns to expand the borders of the Papal States, stripped what bronze remained as well as that from the portico to melt down for cannons.  Romans, as cynical about their rulers then as now, were soon sharing the saying “quod non fecerunt barbari, fecerunt Barberini” (what was not done by the barbarians, was done by the Barberini).

The ass's ears, circa 1860.

Roman architect and Engineer Marcus Vitruvius Pollio (circa 75-10 BC) wrote the influential De architectura which defined the building and aesthesis standards of Classical architecture and the design of the Pantheon follows his rules, height and width exactly match, meaning a perfect sphere would precisely fit inside the dome.  Vitruvius would not have been best pleased at the additions made in the 1600s by Urban VIII.  Sometimes wrongly blamed on Bernini, pontiff turned amateur architect added two bell towers to the sides of the façade which, although disliked by Romans who nicknamed them le orecchie del culo (the ass’s ears), it wasn’t until late in the nineteen century they were finally demolished.

The Pantheon, Rome.

The oculus in the Pantheon is the most famous of the many built by the Romans.  Open to the weather, it allows rain to enter and fall to the floor, where it is carried away through drains. A masterpiece of Roman architectural scale, though it looks small, the oculus’ diameter is 27 feet (8.2m) allowing it to light the building as the sun lights the earth and rain also keeps the building cool during the hot summer months.  A clever trick of lighting (and mathematics) was played out on every 21 April, the founding date of Rome.  At midday, the sunlight hits the metal grille above the door, filling the entrance way with light, timed to coincide with a ceremony at which the emperor appears in the space, reflecting his status as either an earthly god on one on whom the blessings of the gods shone.  Which of these applied depended on the Emperor.  In style, if not scale, the Pantheon was the inspiration for the Große Halle (Great Hall (and referred to in contemporary documents also as the Volkshalle (People's Hall or Ruhmeshalle (Hall of Glory)) which was to be the centrepiece of Germania as Berlin was to be re-named upon becoming the capital of the Third Reich.

Albert Speer's (1905–1981; Nazi court architect 1934-1942; Nazi minister of armaments and war production 1942-1945) post-war memoirs (1969) are not wholly truthful but on matters of architecture they are thought reliable and provide an insight not only into the grandiose plans but also the political and psychological aspects of representational buildings to which Adolf Hitler (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945) attached such importance.  The monumental size alone was significant and despite Hitler being scornful of the mystical notions of some of his paladins, Speer was convinced that inherent in the awe-inspiring scale of the designs was the idea of them becoming places of worship, something which would be reinforced as they aged, unchanged, over the centuries.  Able to accommodate 150-180,000 people, the dome would have had a diameter of 250 metres (825 feet). rising in a slightly parabolic curve to a height of 221 metres (726 feet) while the oculus would be 46 metres (152 feet) in diameter, larger than the entire dome of either the Pantheon (43 metres (142 feet)) or that of St Peter's Basilica (44 metres (145 feet)).  The interior would be 16 times the volume of St Peter's.

Model of the Great Hall intended for Germania.

Speer also noted that even in the late 1930s when first he showed the architectural drawings to Hitler, the Führer suspended belief in facts when it suited him.  Because it was technically possible, Speer originally envisaged building the dome without the use of any structural steel but Hitler objected that were it to be struck by a bomb, the vaulting might be so damaged that without a supporting framework, repairs would be impossible.  Speer conceded the point but when he had questioned whether it was wise to have so tall a structure build in the very heart of the Reich's capital where it would act as a navigational aid for attacking bombers, Hitler breezily replied that Hermann Göring (1893–1946; leading Nazi 1922-1945, Hitler's designated successor & Reichsmarschall 1940-1945) had assured him his Luftwaffe would ensure "no enemy plane will ever enter Germany's skies".  Infamously, the Reichsmarschall would boast to the German people: "If as much as a single enemy aircraft flies over German soil, my name is Meier!"; the Royal Air Force's (RAF) bombing raids on Berlin soon began.

The eye-like feature on a peacock's tail-feathers are called an oculus and because the collective noun for a group of peacocks (peafowl) is "an ostentation" so these several could be styled "an ostentation of oculi".  This photograph is available as a 2024 calendar.

1350-1400: From the Middle English bobel (noun), possibly from the Middle Dutch bobbel and/or Middle Low German bubbele (verb), all probably of echoic origin.  Related forms appear as the Swedish bubbla, the Danish boble 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 which began circa 1711 and collapsed in 1720.  In response to the collapse, 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, many have been describing them as a bubble which will burst and while that has happened with particular coins (the exchange collapses are something different), the industry thus far has continued with only the occasional period of deflation.  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.

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 which is usually regarded as the Dutch tulpenmanie (tulip mania) which bounced during the 1630s, contract prices for some bulbs of the recently introduced and wildly fashionable tulip 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.  In history, there would have been many pervious 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 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 to anything wanting firmness, substance, or permanence is from 1590s.  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.  

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.  Bubble thus began as an an unofficial term used to describe the cluster of people outside the household with whom one felt comfortable in an age of pandemic.

Tulips

Bubbles were however a means of risk-reduction, not a form of quarantine.  The risks in a bubble 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.  Staying home and limiting physical contact with others remained preferable, the next best thing to an actual 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 a 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 support underneath the skirt.   While bouffant gowns could be tea (mid-calf) or floor length, bubble skirts truncate the look hemlines tend to be well above the knee.  Perhaps with a little more geometric accurately, the design is known also as the “puffball” and, in an allusion to oriental imagery, the “harem” skirt.  Fashion designer Christian La Croix 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.

It must have been a memorable silhouette 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 and Hubert de Givenchy experimented in 1954 and 1958, respectively. A year later, Yves Saint Laurent 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 industry in the sense that it would be missing from annual or seasonal ranges, 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, probably about seven or eight.  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 is best when combined with a sleek, fitted top to emphasize the slimness of the waistline, cinched if necessary with a belt some sort of delineating tie.  The bubble needs to be the feature piece too, avoiding details or accessories which might otherwise distract; if one is wearing a partially un-stuffed pillow, the point needs to be made it’s being done on purpose.

The bubble is adaptable although just because something can be done doesn’t mean it should be done.  The bubble skirt has however received the Paris Hilton imprimatur so there’s that.

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.  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 permit a little more swish and flow, a romantic rather than decadent look.  The reception was generally polite but for those who hoped for a different interpretation, history suggests the bubble will be back in a dozen-odd years.

Doomsday

Doomsday (pronounced doomz-dey)

(1) In Christian eschatology, the day of the Last Judgment, at the end of the world (sometimes capital letter); the end of days; the end of times.

(2) Any day of judgment or sentence (sometimes initial capital).

(3) In casual use, the destruction of the world, since the 1950s, by means of nuclear weapons.

(4) As doomsday weapon(s), the device(s) causing the destruction of the world; anything capable of causing widespread or total destruction.

(5) Given to or marked by forebodings or predictions of impending calamity; especially concerned with or predicting future universal destruction.

(6) As Doomsday Clock, a symbolic warning device indicating how close humanity is to destroying the world, run since 1947 as a private venture by the members of the Bulletin of the Atomic Scientists.

Pre 1000: A compound from the Middle English domes + dai from the Old English construct dom (judgment) + dæg (day), dōmesdæg (sometimes dōmes dæg) (Judgment Day) and related to the Old Norse domsdagr.  Dome was borrowed from the Middle French dome & domme (which survives in Modern French as dôme), from the Italian duomo, from the Latin domus (ecclesiae) (literally “house (of the church)”), a calque of the Ancient Greek οἶκος τῆς ἐκκλησίας (oîkos tês ekklēsías); doublet of domus.  Dom was from the Proto-West Germanic dōm and was cognate with the Old Frisian dōm, the Old Saxon dōm, the Old High German tuom, the Old Norse dómr and the Gothic dōms.  The Germanic source was from a stem verb originally meaning “to place, to set”, a sense-development also found in the Latin statutum and the Ancient Greek θέμις (thémis).  Dai had the alternative forms deg, deag & dœg all from the Proto-West Germanic dag; it was cognate with the Old Frisian dei, the Old Saxon dag, the Old Dutch dag, the Old High German tag, the Old Norse dagr and the Gothic dags.

In medieval England, doomsday was expected when the world's age had reached 6,000 years from the creation, thought to have been in 5200 BC and English Benedictine monk, the Venerable Bede (circa 672-735) complained of being pestered by rustici (the "uneducated and coarse-mannered, rough of speech"), asking him "how many years till the sixth millennium be endeth?"  However, despite the assertions (circa 1999) of the Y2K doomsday preppers, there is no evidence to support the story of a general panic in Christian Europe in the days approaching the years 800 or 1000 AD.  The use to describe a hypothetical nuclear bomb powerful enough to wipe out human life (or all life) on earth is from 1960 but the speculation was the work of others than physicists and the general trend since the 1960s has been towards smaller devices although paradoxically, this has been to maximize the destructive potential through an avoidance of the "surplus ballistic effect" (ie the realization by military planners that blasting rubble into to smaller-sized rocks was "wasted effort and bad economics").

The Domesday Book

Domesday is a proper noun that is used to describe the documents known collectively as the Domesday Book, at the time an enormous survey (a kind of early census) ordered by William I (circa 1028-1087; styled usually as William the Conqueror, King of England 1066-1087) in 1085.  The survey enumerated all the wealth in England and determined ownership in order to assess taxes.  Domesday was the Middle English spelling of doomsday, and is pronounced as doomsday.

Original Domesday book, UK National Archives, London.

The name Domesday Book (which was Doomsday in earlier spellings) was first recorded almost a century after 1086.  An addition to the manuscript was made probably circa 1114-1119 when it was known as the Book of Winchester and between then and 1179, it acquired the name by which it has since been known.  Just to clarify its status, the Treasurer of England himself announced “This book is called by the native English Domesday, that is Day of Judgement” (Dialogus de scaccario), adding that, like the Biblical Last Judgment, the decisions of Domesday Book were unalterable because “… as from the Last Judgment, there is no further appeal.”  This point was reinforced by a clause in the Dialogue of the Exchequer (1179) which noted “just as the sentence of that strict and terrible Last Judgement cannot be evaded by any art or subterfuge, so, when a dispute arises in this realm concerning facts which are written down, and an appeal is made to the book itself, the evidence it gives cannot be set at nought or evaded with impunity.”  It was from this point that began in England the idea of the centralised written record taking precedence over local oral traditions, the same concept which would evolve as the common law.

The Doomsday Book described in remarkable detail the landholdings and resources of late eleventh century England and is illustrative of both the power of the government machine by the late medieval period and its deep thirst for information.  Nothing on the scale of the survey had been undertaken in contemporary Europe, and was not matched in comprehensiveness until the population censuses of the nineteenth century although, Doomsday is not a full population census, the names appearing almost wholly restricted to landowners who could thus be taxed.  It was for centuries used for administrative and legal purposes and remains often the starting point for many purposes for historians but of late has been subject to an increasingly detailed textual analysis and it’s certainly not error-free.

The Doomsday Clock

The Doomsday Clock is a symbol that represents the likelihood of a man-made global catastrophe.  Maintained since 1947 by the members of the Bulletin of the Atomic Scientists (BOTAS), the clock was created as a metaphor for threat to humanity posed by nuclear weapons.  On the clock, a hypothetical global catastrophe is represented as the stroke of midnight and BOTAS’s view of the closeness to that hour being reached by the number of minutes or seconds to midnight.  Every January, BOTAS’s Science and Security Board committee meets to decide where the second-hand of the clock should point and in recent years, other risk factors have been considered, including disease and climate change, the committee monitoring developments in science and technology that could inflict catastrophic damage.

Lindsay Lohan and her lawyer in court, Los Angeles, December 2011.

These concerns do have a long history in philosophy and theology but the use in 1945 of nuclear fission to create atomic weapons focused the minds of many more on the possibilities, the concerns growing in the second half of the twentieth century as the bombs got bigger and proliferated extraordinarily to the point where, if all were detonated in the right place at the right time, almost everyone on Earth would have been killed several times over.  At least on paper, the threat was real and even before Hiroshima made the world suddenly aware of the matter, there had been some in apocalyptic mood: Winston Churchill's (1875-1965; UK prime-minister 1940-1945 & 1951-1955) “finest hour” speech in 1940 warning of the risk civilization might “…sink into the abyss of a new Dark Age made more sinister, and perhaps more protracted, by the lights of perverted science”.  It had been a growing theme in liberal interwar politics since the implications of technology and the industrialisation of warfare had been writ large by the World War I (1914-1918).

HG Wells’ (1866–1946) last book was Mind at the End of its Tether (1945), a slim volume, best remembered for the fragment “…everything was driving anyhow to anywhere at a steadily increasing velocity”, seemingly describing a world which had become more complicated, chaotic and terrifying than anything he had prophesized in his fiction. In this it’s often contrasted with the spirit of cheerful optimism and forward-looking stoicism of the book he published a few months earlier, The Happy Turning (1945), but that may be a misreading.  Mind at the End of its Tether is a curious text, easy to read yet difficult to reduce to a theme; in his review, George Orwell (1903-1950) called it “disjointed” and it does have a quality of vagueness, some chapters hinting at despair for all humanity, others suggesting hope for the future.  It’s perhaps the publication date that tints the opinions of some.  Although released some three months after the first use of atomic bombs in August 1945, publishing has lead-times and Wells hadn’t heard of the A-bomb at the time of writing although, he had in 1914 predicted such a device in The World Set Free.  In writing Mind at the End of its Tether, Wells, the great seer of science, wasn’t in dark despair at news of science’s greatest achievement, nuclear fission, but instead a dying man disappointed about the terrible twentieth century which, at the end of the nineteenth, had offered such promise.

In 1947, though the USSR had still not even tested an atomic bomb and the US enjoyed exclusive possession of the weapon, BOTAS was well aware it was only a matter of time and the clock was set at seven minutes to midnight.  Adjustments have been made a couple of dozen times since, the most optimistic days being in 1991 with the end of the Cold War when it was seventeen minutes to midnight and the most ominous right now, BOTAS in 2023 choosing 90 seconds, ten seconds worse than the 100 settled on in 2020.

The committee each year issues an explanatory note and in 2021 noted the influences on their decision.  The COVID-19 pandemic was a factor, not because it threatened to obliterate civilization but because it “…revealed just how unprepared and unwilling countries and the international system are to handle global emergencies properly. In this time of genuine crisis, governments too often abdicated responsibility, ignored scientific advice, did not cooperate or communicate effectively, and consequently failed to protect the health and welfare of their citizens.  As a result, many hundreds of thousands of human beings died needlessly”.  COVID-19 they noted, will eventually recede but the pandemic, as it unfolded, was “a vivid illustration that national governments and international organizations are unprepared to manage nuclear weapons and climate change, which currently pose existential threats to humanity, or the other dangers—including more virulent pandemics and next-generation warfare—that could threaten civilization in the near future”.  In 2023, the adjustment was attributed mostly to (1) the increased risk of the use of nuclear weapons after the Russian invasion of Ukraine, (2) climate change, (3) biological threats such as COVID-19 and (4) the spread of disinformation through disruptive technology such as generative AI (artificial intelligence).

The acceleration of nuclear weapons programs by many countries was thought to have increased instability, especially in conjunction with the simultaneous development of delivery systems increasingly adaptable to the use of conventional or nuclear warheads.  The concern was expressed this “may raise the probability of miscalculation in times of tension”.  Governments were considered to have “…failed sufficiently to address climate change” and that while “fossil fuel use needs to decline precipitously if the worst effects of climate change are to be avoided”, instead “…fossil fuel development and production are projected to increase”.  Political factors were also mentioned including the corrosive effects of “false and misleading information disseminated over the internet…, a wanton disregard for science and the large-scale embrace” of conspiracy theories often “driven by political figures”.  They did offer a glimmer of hope, notably the change of administration in the US to one with a more aggressive approach to climate change policy and a renewed commitment to nuclear arms control agreements but it wasn’t enough to convince them to move the hands of the clock.  It remains a hundred seconds to midnight.

The clock is not without critics, even the Wall Street Journal (WSJ) expressing disapproval since falling under the control of Rupert Murdoch (b 1931).  There is the argument that after seventy years, its usefulness has diminished because over those decades it has become "the boy who cried wolf": a depiction of humanity on the precipice of the abyss yet life went on.  Questions have also been raised about the narrowness of the committee and whether a body which historically has had a narrow focus on atomic weapons and security is adequately qualified to assess the range of issues which should be considered.  Mission creep too is seen as a problem.  The clock began as a means of expressing the imminence of nuclear war.  Is it appropriate to use the same mechanism to warn of impending climate change which has anyway already begun and is likely accelerating?  Global thermo-nuclear war can cause a catastrophic loss of life and societal disruption within hours, whereas the climate catastrophe is projected to unfolds over decades and centuries.  Would a companion calendar be a more helpful metaphor?  The criticism may miss the point, the clock not being a track of climate change but of political will to do something to limit and ameliorate the effects (everyone having realised it can’t be stopped).

Xanadau

Xanadu (pronounced zan-a-du)

Also known as Shangdu, Xanadu was the capital of Kublai Khan's (1215-1294) Yuan dynasty (1271-1368) in China, before he decided to move his throne to the Jin dynasty (1115-1234) capital of Zhōngdū (middle capital), which he renamed Khanbaliq, later known in the West as Peking and of late, Beijing.  Xanadu then became his summer capital.  Xanadu was visited by the Venetian merchant Marco Polo (circa 1254–1324) in about 1275, and was destroyed in 1369 by the Ming army under Zhu Yuanzhang (1328-1398).

Relic site of Xanadu.  Xanadu was located in what is now called Inner Mongolia, 220 miles (350 km) north of what is no the city of Beijing (Peking).  Today, only ruins remain, surrounded by a grassy mound that was once the city walls. Since 2002, restoration work has been undertaken and in June 2012, Shangdu was made a World Heritage Site.

Kubla Khan (1797) by Samuel Taylor Coleridge (1772-1834)

By his own account, Samuel Taylor Coleridge was reading about Shangdu while taking laudanum, an opium based medicine.  It led to an opium-induced dream, during which he composed some three-hundred lines of verse.  As soon as he awoke, he wrote down the first fifty but unfortunately, was then interrupted by “a man on business from (the local Somerset village of) Porlock.”   Once the business was concluded, Coleridge found the distraction had driven from his mind the rest of the poem.  All find Coleridge’s story charming but scholars doubt it’s true, the poet having used a similar excuse years before.  Most think it a case of writer’s block.

In Xanadu did Kubla Khan
A stately pleasure-dome decree:
Where Alph, the sacred river, ran
Through caverns measureless to man
Down to a sunless sea.
So twice five miles of fertile ground
With walls and towers were girdled round:
And here were gardens bright with sinuous rills
Where blossomed many an incense-bearing tree;
And here were forests ancient as the hills,
Enfolding sunny spots of greenery.
But oh! that deep romantic chasm which slanted
Down the green hill athwart a cedarn cover!
A savage place! as holy and enchanted
As e'er beneath a waning moon was haunted
By woman wailing for her demon-lover!
And from this chasm, with ceaseless turmoil seething,
As if this earth in fast thick pants were breathing,
A mighty fountain momently was forced;
Amid whose swift half-intermitted burst
Huge fragments vaulted like rebounding hail,
Or chaffy grain beneath the thresher's flail:
And 'mid these dancing rocks at once and ever
It flung up momently the sacred river.
Five miles meandering with a mazy motion
Through wood and dale the sacred river ran,
Then reached the caverns measureless to man,
And sank in tumult to a lifeless ocean:
And 'mid this tumult Kubla heard from far
Ancestral voices prophesying war!
The shadow of the dome of pleasure
Floated midway on the waves:
Where was heard the mingled measure
From the fountain and the caves.
It was a miracle of rare device,
A sunny pleasure-dome with caves of ice!
A damsel with a dulcimer
In a vision once I saw:
It was an Abyssinian maid,
And on her dulcimer she played,
Singing of Mount Abora.
Could I revive within me
Her symphony and song,
To such a deep delight 't would win me
That with music loud and long,
I would build that dome in air,
That sunny dome! those caves of ice!
And all who heard should see them there,
And all should cry, Beware! Beware!
His flashing eyes, his floating hair!
Weave a circle round him thrice,
And close your eyes with holy dread,
For he on honey-dew hath fed,
And drunk the milk of Paradise.

Dome

Dome (pronounced dohm)

(1) In architecture, a vault, having a circular plan and usually in the form of a portion of a sphere, so constructed as to exert an equal thrust in all directions.

(2) A domical roof or ceiling; a polygonal vault, ceiling, or roof.

(3) Any covering thought to resemble the hemispherical vault of a building or room; anything shaped like a hemisphere or inverted bowl.

1505–1515: From the Middle French domme & dome (a town-house; a dome, a cupola) (which persists in modern French as dôme), from the Provençal doma, from the Italian duomo (cathedral), from the Medieval Latin domus (ecclesiae; literally “house (of the church)”), a calque of the Ancient Greek οἶκος τῆς ἐκκλησίας (oîkos tês ekklēsías).  Dome is a noun & verb, domed & doming are verbs and domelike, domical, domish & domesque are adjectives; the noun plural is domes.

By the 1650s, the formalized use in architecture ensured the meaning was (more or less) standardized as “a round, vaulted roof, a hemispherical covering of a building” and thus the ultimate specialized evolution from the Greek dōma (a house, housetop (used especially of those with a roof “in the eastern style”), from domos (house), from the primitive Indo-European root dem- (house, household).  The medieval use of the German dom and Italian duomo as verbal shorthand for “cathedral” (essentially a clipping from “house of God”) was picked up in the imperfect way so many words entered English to describe architectural features in the style of hemispherical cupolas, the domes at the intersection of the nave and the transept, or over the sanctuary, characteristic architectural feature of Italian cathedrals.  The sense in English of “a building, a house” had been borrowed in English as early as the 1510s and was used mostly of stately homes and it endures but only as a literary device and it’s rarely seen outside of poetry.

The shape occurs to one degree or another in nature and is common in man-made objects and the built environment so dome is an often seen modifier (cake dome, pleasure dome, lava dome; onion dome et al) and appears in the opening lines of one of the most cherished fragments of English verse: Kubla Khan (1797) by Samuel Taylor Coleridge (1772-1834).

In Xanadu did Kubla Khan
A stately pleasure-dome decree:
Where Alph, the sacred river, ran
Through caverns measureless to man
Down to a sunless sea.

Some of the use has also been opportunistic and not especially domical.  Vistadomes were raised, glass-enclosed sections built into the roofs of railway carriages, placed over an elevated section of seats to afford passengers a better view of the scenery.  The idea was picked up by General Motors, the Oldsmobile Vista Cruiser station wagon (1964-1977), the Buick Roadmaster Estate (1991-1996) and the Scenicruiser busses (1954-1956 and made famous in the Greyhound livery some wore until the 1970s) all used raised, partially-windowed sections although none were officially described as “domes”.

The Hagia Sophia, now the main mosque in Istanbul; the minarets were added after the fall of Constantinople to the Ottoman Turks in 1453 and there are many architectural critics who maintain visually they improve the balance of the structure.  The illustration on the right shows how the Byzantine engineers used pendentives to make the construction of domes possible.     

Domes however are most associated with grand-scale, representational architecture (although quite a few builders of McMansions found them hard to resist).  One intriguing aspect of structural engineering upon which the integrity of a dome depends on what are called pendentives (the triangular segments of the lower part of a hemispherical dome left by the penetration of the dome by two semicircular vaults intersection at right angles).  Dating from 1727, pendentive was from the mid-sixteenth century French pendentif, from the Latin pendentem (nominative pendens) (hanging and the source of the English “pendulous”), the present participle of pendere (to hang) from the primitive Indo-European roots pen & spen- (to draw, stretch, spin).  What pendentives permit is the use of a circular dome over a square void square room or an elliptical one over something rectangular room.  Pendentives, (geometrically the triangular segments of a sphere), taper to points at the bottom and spread at the top to establish the continuous circular or elliptical base as required.  As structural supports, pendentives distribute the bulk of a dome’s weight to the four corners (the strongest points) and ultimately to the piers and the foundations below.  The classic example is the Hagia Sophia, the sixth century Byzantine cathedral at Constantinople (modern day Istanbul).  It was converted into a mosque when Constantinople fell to the Ottoman Turks in 1453 and, after a century-odd as a museum, is again a mosque.

Scale model of Germania.  Hitler would spend hours pondering the details but in 1945, he spent even longer looking at the model of what was planned for the Austrian city of Linz where he'd decided to have his tomb installed.

Domes have long been a favorite of emperors, dictators and those other megalomaniacs: architects.  A truly monumental one would have been the Volkshalle (People's Hall and known also as the Große Halle (Great Hall) & Ruhmeshalle (Hall of Glory), the centerpiece of Adolf Hitler’s (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945) never realized plan to re-built Berlin as Germania, a worthy Welthauptstadt (world capital) of his “thousand year Reich”.  Although Albert Speer (1905–1981; Nazi court architect 1934-1942; Nazi minister of armaments and war production 1942-1945) was Germania’s chief architect, in some aspects he was really a glorified draftsman, correcting the technical errors in the drawings passed to him by the Führer who had be sketching parts of the design since the early 1920s.

Even by the standards of the super-dimensionality which was characteristic of the Third Reich, the domed hall would have been extraordinary.  The oculus would have been 46 m (151 feet) in diameter which would have accommodated the entire rotunda of Hadrian's Pantheon and the dome of St Peter's Basilica.  The  250 m (820 feet) diameter of the dome was (and this was a signature of Speer’s approach), bigger even than Hitler had requested and he was much displeased to learn of a rival architect’s plans for a dome 15 m (49 feet) greater in diameter to sit atop the city’s new railway station.  As things turned out, none of the grandiose structures were ever built and although a tinge of regret can be found in Speer’s post-war thoughts, even he admitted the designs were a failure because of “their lack of human scale”.

Berlin's rebuilt Reichstag with steel & glass dome.

Berlin did however eventually get a new dome, albeit it one rendered not in granite but the glass and steel the Führer thought was fine for factories and warehouses but which would have appalled him as a method of construction for public, representational architecture.  Plonked atop the rebuilt Reichstag, it was said to symbolize the reunification of Germany although quite how it managed that has never really been explained although the distinctive structure has become a city landmark and people seem to like it.  A clever design, it sits directly above the chamber of the Bundestag (the lower house of the bicameral federal parliament) and permits public observation, the clever design also reducing energy use by optimizing the input of natural light while moving shrouds minimize glare and heat-soak.

Cinerama Dome, Los Angeles in 1965, the year of its greatest commercial success.

The Cinerama Dome movie theatre sits on Hollywood’s Sunset Boulevard.  Opened in 1963, the Cinerama Dome introduced a new concept for film projection, a curved screen which sat inside a geodesic dome based on the design developed by US systems theorist & architect Richard Buckminster Fuller (1895–1983), one attraction of which was such things could be built at lower coast and in much less time than a conventional theatre building.  Intended to be the first of perhaps thousands around the planet, it was built in a still remarkable four months but it remains the only concrete geodesic on the planet and while it has operated intermittently since being closed during the COVID-19 pandemic, its future is uncertain and although it will probably be preserved as a historic building, it’s likely to be re-purposed as retail or restaurant space.

The end of the line for Cinerama is another marker in the evolution of the technology which underpinned the evolution of the US economy from one based on agriculture, to one increasingly industrial to one geared around the military & entertainment.  In the 1950s, cinema’s greatest challenge came from television and the film studios fought back by creating differentiation in their products.  The venture into 3D proved a cul-de-sac for a number of reasons but one thing cinemas could do was make their big screens huge and during the 1950s the wide-screen Cinemascope enjoyed a boom.  However, there was a limit to how much screens could grow, hence the interest in Cinerama which projected onto a curved screen designed to take advantage of the way the human eye sees and processes images, the system at its best when provided by three synchronized projectors.  The idea lives on in the curved screens which have become popular among gaming freaks who enjoy the sense of “envelopment”.  It was also the era during which populations moved further from city centres into suburbs and thus, cinemas also needed to move, more of which (but often smaller) would be required.  Thus the attraction of the geodesic dome came which, largely pre-fabricated, was cheap to produce and quick to assemble.  However, Cinerama was expensive to film, to print, to produce and the sheer size and weight of the prints meant it was costly even to ship the material to venues and the conversion process to something which could be used with conventional projection.

Heat Domes

July 2023 Global heat map from the Climate Change Institute, University of Maine, USA.  For those unconvinced, Fox News continues to provide alternative facts.

The “heat dome” is a weather phenomenon, the physics of which has for decades been understood but of late the term has entered general use as much of the northern hemisphere has suffered from prolonged, unusually high temperatures, July 2023 measured as the hottest month ever recorded.  A heat dome occurs when a large, high-pressure system traps and concentrates hot air in a specific region, leading to prolonged and extremely high temperatures. Under a heat dome, the atmospheric pressure aloft prevents the hot air from rising and dissipating, effectively acting as a lid or cap over the area, thus the image of a dome sitting over the land.

The UK's Royal Meteorological Service's simple illustration of the physics of a heat dome.  Heat domes are also their own feedback loop.  A static areas of high pressure which already contains warm or hot air trapped under the high will become hotter and hotter, creating a heat dome.  Hot air will rise into the atmosphere, but high pressure acts as a lid and causes the air to subside or sink; as the air sinks, it warms by compression, and the heat builds. The ground also warms, losing moisture and making it easier to heat even more.
