Omicron

Omicron (pronounced om-i-kron or oh-mi-kron)

(1) The fifteenth letter of the Classical and Modern Greek alphabet and the sixteenth in Ancient archaic Greek; a short vowel, transliterated as o.

(2) The vowel sound represented by this letter.

(3) The common name designated (on 26 November 2021 by the World Health Organization’s (WHO) Technical Advisory Group on Virus Evolution (TAG-VE)) for the variant B.1.1.529 of the SARS-CoV-2 virus which causes the condition COVID-19.

(4) In English, as “o” & “O” (fifteenth letter of the alphabet), a letter used for various grammatical and technical purposes.

Circa 1400: The fifteenth letter of the Greek alphabet (oʊmɪkrɒn; the symbol Oo), literally "small o" (ὂ μικρόν (ò mikrón)), the construct being o + the Ancient Greek (s)mikros (small (source of the modern micro-) and so-called because the vowel was "short" in ancient Greek.  Omega (O) was thus the “long” (O) and omicron the “short” (o).  It’s from omicron both Latin and Cyrillic gained “O”.  Depending on the context in which it’s being written, the plural is omicrons or omicra.

The fifteenth letter of the Greek alphabet was derived from a character which in Phoenician was called 'ain or ayin (literally "eye") and represented by what most dictionaries record as something like "a most peculiar and to us unpronounceable guttural sound".  The Greeks also lacked the sound, so when they adopted characters from the Phoenician alphabet, arbitrarily they changed O's value to a vowel.  Despite the medieval belief, there is no evidence to support the idea the form of the letter represents the shape the mouth assumes in pronouncing it.  The Greeks later added a special character for the "long" O (omega), and the original thus became the "little o" (omicron).  In Middle English and later colloquial use, o or o' has a special use as an abbreviation of “on” or “of”, and remains literary still in some constructions (o'clock, Jack-o'-lantern, tam-o'-shanter, cat-o'-nine-tails, will-o'-the-wisp et al).  The technical use in genealogy is best represented by Irish surnames, the “O’” from the Irish ó (ua), which in the Old Irish was au (ui) and meant "descendant".

As a connective, -o- is the most common connecting vowel in compounds either taken or formed from Greek, where it is often the vowel in the stem.  English being what it is, it’s affixed, not only to constructions purely Greek in origin, but also those derived from Latin (Latin compounds of which would have been formed with the L. connecting or reduced thematic vowel, -i).  The Oxford English Dictionary (OED) adds the usage note that this occurred especially when what was wanted were compounds with a sense of Latin composition, which even if technically possible, would not be warranted but, were correct under the principles of Greek composition.  Similarly, blood type-O was in 1926 originally designated “0” (zero)" denoting the absence of any type-A & B agglutinogens but the letter O was adopted to align the group with existing nomenclature.  The standardized scale in railroads (O=1:48 (1:25 gauges)) dates from 1905.

As the character to represent the numerical value "zero", in Arabic numerals it is attested from circa 1600, the use based on the similarity of shape.  The similarity would later cause a Gaëtan Dugas (1952–1984), a Québécois Canadian flight attendant, mistakenly to be identified as "Patient Zero" (the primary case for HIV/AIDS in the United States).  The error happened because of a mistake made in 1984 in either the reading or transcription of a database maintained by the Center for Disease Control and Prevention (CDC) which tracked the sexual liaisons and practices of gay and bisexual men, mostly those from California and New York. Dugas, because he was statistically unusual in having no relevant connections with either state, was coded as "Patient O" (indicating out-of-state) but this was at some point misinterpreted as "Patient 0 (Zero)".  Dugas was later identified as "Patient Zero" (ie the person who introduced HIV/AIDS to North America) in Randy Shilts's (1951-1994) book And the Band Played On: Politics, People, and the AIDS Epidemic (1987) which explored the outbreak of the AIDS epidemic in the United States.  Shilts would later dismiss the significance of the technical error, claiming it made no difference to his point that Dugas engaged in behavior by which he either carelessly, recklessly or intentionally infected his many sexual partners with HIV (a claim subsequently contested by others).  Shilts died in 1994 from an AIDS-related condition.

Flirting with risk of exposure to, inter-alia, Omicron: Lindsay Lohan in facemask during the Covid-19 pandemic.

The authorities discourage the use of masks with the one-way, non-return valves (this one a twin-valve model) during epidemics & pandemics because, while affording the usual protection to the wearer, there is a slight reduction in their effectiveness in reducing the risk of infecting others.

A variant of the original SARS-CoV-2 virus which causes Covid-19, Omicron (B.1.1.529) was first reported to the World Health Organization (WHO) in November 2021 after being detected in Botswana.  Rapidly, it out-competed other SARS-CoV-2 strains to become the predominant variant in circulation, the primary transmission vector of that thought to be international air travel.  The WHO’s Technical Advisory Group on Virus Evolution (TAG-VE) named variant B.1.1.529 “Omicron” in November 2021, skipping the Greek letters next in sequence (nu (Ν, ν) & xi (Ξ ξ)), the former not used because of the confusion envisaged by virtue of the English pronunciation (“new” virus) and the latter avoided so the feelings of Xi Jinping (b 1953; general secretary of the Chinese Communist Party (CCP) and paramount leader of the People's Republic of China (PRC) since 2013) weren’t hurt, the origins of Covid-19 being a sensitive issue among the CCP’s Central Committee.

Flirting virus: Omicron FLiRT variant.

Although a number of Omicron sub-variants have subsequently been identified, none has been found so structurally dissimilar that the TAG-VE felt constrained to allocate a different Greek letter.  Instead, such variants were tagged alpha-numerically according to the group’s established convention (BA.1, BA.2 etc; identified sub-variants of BA.5 listed in a BQ.n sequence).  By June 2024, Omicron and its sub-variants remain dominant globally although new strains continue to emerge, notably the “FLiRT" which sounds encouraging but the US Centre for Disease Control (CDC) provided a rather dry explanation: “F for L at position 456, and R for T at position 346 (references to specific mutations in the virus’s spike protein).  The FLiRT variants are sub-variants of the Omicron JN.1 strain and include notable strains such as KP.2, KP.3, and KP.1.1.  The FLiRT variants now account for a significant portion of cases in the United States.

The Omicron and others: Notable Lancias

1981 Lancia Beta Spyder (Zagato).

Vincenzo Lancia (1881–1937) used letters from the Greek alphabet (Alpha, Beta, Lambda, Kappa, Omicron et al) as model names for many of his early vehicles and in 1953 returned to the practice for a one-off range based on a commercial chassis.  However, when the Beta (1972-1984) was released in 1972 it was the first time since 1945 the company had used letters from the Greek to designate a passenger vehicle.  It wasn’t Lancia’s first use of Beta, that had been the 1909 car which replaced the Alpha (also Alfa) and, although the 1972 car had been intended to be the model which would symbolize Lancia’s re-birth (il risorgimento), Beta rather than Alfa was chosen to avoid confusion with Alfa Romeo.  Over time, the Beta would be offered with two four-door saloon bodies and a coupé from which two variants were derived: (1) a three-door estate labeled HPE (high-performance estate) in the tradition of the "shooting brake" (a la the Reliant Scimitar et al) and (2) as a co-project with Lombardy-based coach-builder Zagato, a targa-style convertible with a structural arrangement vaguely similar to that used by the Triumph Stag.  In some markets, in an attempt to enhance the image, the Montecarlo sports car was badged as a Beta.  The survival rate of the Betas was low because of chronic rust but the oft-told tale the steel was of poor quality (described as “porous” and obtained in some sort of barter transaction between Italy and the Soviet Union) has been debunked, the Betas (like to contemporary Alfa Romeo Alfasud) crumbling away because of design flaws, inadequate corrosion-prevention measures and poor build quality, the latter due in part to the appalling state of the relations between capital & labor during the troubled 1970s.

1987 Lancia Thema 8·32.

By the standards of European front wheel drive mass-production, the Lancia Thema (1984-1994 and available as a four-door saloon, a five door estate and a low-volume long wheelbase (LWD) limousine) was completely conventional and mostly unexceptional but there was one memorable diversion: the Thema 8·32.  Introduced at the 1986 Turin Motor Show, instead of the predictable variety of four & six-cylinder petrol and diesel engines used in the mainstream range, the 8·32 was fitted with a version of the 3.0 litre V8 Ferrari used in their 308 and Mondial models.  By the mid-1980s, although it was no longer novel to put powerful engines into previously nondescript saloons, the 8·32 was in the avant garde of the more extreme, pre-dating the BMW M5 (E28) by some months and the Mercedes-Benz 500E (W124) by seven years but what made it truly bizarre was it retained the Thema’s front wheel drive (FWD) configuration.  That probably sounds like the daftest idea since Oldsmobile and Cadillac in the mid 1960s decided to offer big FWD "personal coupes" (which eventually would be offered with V8 engines as large as 500 cubic inches (8.2 litre)) but journalists who tested the 8·32 declared it a surprisingly good good road car although those who tried them on racetracks did note the prodigious understeer.  Ferrari supplying Lancia with a V8 was actually returning a favor: In 1954, it was the Lancia D50 Formula One car which became the first Ferrari V8.  By 1986, even the V8-powered Cadillac DeVille range had switched to FWD but it was a very different machine from the 8·32 and many DeVille owners probably neither noticed nor cared the configuration had changed although they would have appreciated the flat floor and additional interior space.

1974 Lancia Stratos HF.

The 8·32 experiment (which Lancia opted not the repeat) wasn’t the first time Ferrari had provided engines for a Lancia. The Stratos HF (1973-1978, the HF standing for "High Fidelity", a moniker sometimes attached to Lancia’s high performance variations) was named after the Stratos Zero, a 1970 show car designed by Bertone’s Marcello Gandini (1938–2024) although, except conceptually, the production vehicle bore little resemblance to that which lent the name.  The diminutive wedge was powered by the 2.4 litre V6 with which Ferrari used in the Dino 246 (1969-1974) and it was one of the outstanding rally cars of the 1970s, winning the 1974 Targa Florio and taking the World Rally Championship (WRC) in 1974, 1975 & 1976.  Still competitive in the late 1970s when factory support was withdrawn because Fiat, the conglomerate which by then owned Lancia, wished to use its activities in motorsport to promote more mainstream models, it continued in private hands to win events into the 1980s and replicas have since been produced.  Such is the appeal of the Stratos that Torino-based coach-builder Manifattura Automobili in 2018 announced a run (said to be limited to 25) of the "New Stratos", based on the (shortened) platform of a Ferrari 430 Scuderia (2007). 

1971 Lancia 2000 Coupé.

The Lancia Flavia was in production between 1961 and 1971 before it was re-named the 2000, a reference to the two litre flat-four, introduced in 1969, an enlarged version of the power-plant which, in 1.5 and 1.8 litre form had powered the Flavia.  Although a decade old at its introduction, the 2000 was still of an advanced specification including the then still uncommon option of fuel-injection.  Although the earlier Flavias were built as four-door saloons, two-door coupés & convertibles (including a quite strange looking coupé by Zagato), the 2000 was offered only with saloon and coupé coachwork, the latter so elegant that most were prepared to forgive the FWD beneath, something the Lancia cognoscenti (a most devoted crew) inexplicably believe is a good idea.

1983 Lancia 037.

The last rear-wheel drive car to win the WRC, the 037 (the mysterious name merely a carry-over of the original project name) was a highly modified version of the Montecarlo, a Pininfarina-designed mid-engined coupé produced between 1975 to 1981 (in some markets called the Beta Montecarlo to maintain a link with the more mainstream Beta models and in North America sold as the Scorpion).  The Montecarlo had begun life as a project undertaken by Pininfarina to replace Fiat’s much admired but outdated 124 Coupé but Bertone’s X1/9 design was thought so outstanding it was instead chosen for immediate production while the 124 continued.  Pininfarina’s bigger, heavier car was then designated the Fiat X1/8, envisaged to compete as an up-market, mid-engined, three litre V6 sports car.  However, after the first oil shock in 1973, the market was re-evaluated and, now code-named named X1/20, it was re-positioned as a two litre, four cylinder car and handed to Lancia to become the Montecarlo.  In development since 1980, the competition version, the Lancia Rally 037, was released late the next year and in its first competitive season in Group 5 rallying proved fast but still fragile although, it was certainly promising enough for the factory to return in 1983 when, fully developed, it won the WRC.  It was however the end of an era, the 037 out-classed late in the season by the all-wheel-drive competition which has since dominated the WRC.  In one aspect however it remains a WRC benchmark: no competitor since has looked as good.

1971 Lancia Fulvia 1.3 Coupé.

The slightly frumpy looking Fulvia saloon was the mass-selling (a relative term) model of Lancia’s range between 1963-1976 but the memorable version was the exquisite coupé (1965-1977).  Mechanically similar to the saloon except that it was on a short wheelbase  (SWB) platform and the FWD Fulvias were only ever offered with V4 engines of modest displacement (1.1-1.6 litres), the relatively high-performance achieved by virtue of light weight, high specific output and, in the two-door versions, a surprisingly efficient aerodynamic profile, belying the rather angular appearance (except for the usual special coupes by Zagato which managed almost to look attractive, not something which could be guaranteed to emerge from their drawing boards).  The HF versions were built for competition with more spartan interior trim, aluminum doors & non-structural panels, the engines tuned for higher power.  Produced in small runs, the early Flavia HFs used quite highly-strung 1.2 & 1.3 litre engines (the last batch gaining a five-speed gearbox) but the definitive competition HF was released in 1969 with a 1.6 litre engine and nicknamed Fanalona (big headlamps), an allusion to the seven inch units which had replaced the earlier five inch versions.  Almost mass-produced by earlier standards, over thirteen hundred were build and it delivered for the factory-supported Squadra Corse team, winning the 1972 Monte Carlo Rally.  The success inspired the factory to capitalize on the car’s success, a purely road-going version, the 1600 HF Lusso (Luxury) with additional interior appointments and without the lightweight parts manufactured between 1970-1973.  This one really was mass-produced; nearly four thousand were made and they remain much coveted.

1930 Lancia Omicron with two and a half deck arrangement and a clerestoried upper windscreen.

The Lancia Omicron was a bus chassis produced between 1927-1936; over 600 were built in different wheelbase lengths with both two and three-axle configurations.  Most used Lancia's long-serving, six-cylinder commercial engine but, as early as 1933, some had been equipped with diesel engines which were tested in North Africa where they proved durable and, in the Sudan, Ethiopia, Libya and Algeria, once petrol powered Omicron chassis were being re-powered with diesel power-plants from a variety of manufacturers as late as the 1960s.  Typically of bus use, coachbuilders fabricated many different styles of body but, in addition to the usual single and double deck arrangements, the Omicron is noted for a number of two and a half deck models, the third deck configured usually as a first-class compartment but in at least three which operated in Italy, they were advertised as “smoking rooms”, the implication presumably that the rest of the passenger compartment was smoke-free.  History doesn't record if the bus operators were any more successful in enforcing smoking bans than the usual Italian experience.

1928 Lancia Lambda series 7 tipo Siluro Bateaux (torpedo) "Casaro".

One of the most innovative designs of the 1920s, the Lamba was produced between 1922-1931 and was the first car to enter volume production using a stressed, unitary body.  It featured very effective four-wheel brakes (something surprisingly rare at the time) and independent front suspension, the competence of which was such that it was able to more than match the point-to-point performance of many cars much more powerful but with more brutishly simple solid axles attached to a chassis.  However, because it was so attractive, demand much exceeded Lancia’s capacity to build sufficient numbers and the factory was forced to offer a model with a conventional chassis so coach-builders could provide bodies to fill the supply gap.  All Lambdas were powered by advanced and compact narrow-angle aluminum overhead camshaft V4 engines between 2.1-2.6 litres and over eleven thousand were built.
