Quarantine (pronounced kwawr-uhn-teen
or kwor-uhn-teen)
(1) In historic English common law, the period
of 40 days during which a widow was entitled to remain in her deceased
husband's home while any dower is collected and returned.
(2) A strict isolation imposed to prevent
the spread of disease and (by extension), any rigorous measure of isolation,
regardless of the reason.
(3) A period, originally 40 days (the
historic understanding of the maximum known incubation period of disease) of
detention or isolation imposed upon ships, persons, animals, or plants on
arrival at a port or place, when suspected of carrying some infectious or
contagious disease; a record system kept by port health authorities in order to
monitor and prevent the spread of contagious diseases. The origin was in measures taken in 1448 in Venice's
lazaret to avoid renewed outbreaks of
the bubonic plague.
(4) In historic French law, a 40-day period
imposed by the king upon warring nobles during which they were forbidden from
exacting revenge or to continue warfare.
(5) A place where such isolation is
enforced (a lazaret).
(6) In international relations, a blockade
of trade, suspension of diplomatic relations, or other action whereby one
country seeks to isolate another.
(7) In computing, a place where files
suspected of harboring a computer virus or other harmful code are stored in a
way preventing infection of other files or machines; the process of such an
isolation.
(8) To withhold a portion of a welfare
payment from a person or group of people (Australia).
(9) To quarantine someone or something.
1600–1610: From the Middle English quarentine (period a ship suspected of
carrying contagious disease is kept in isolation), from the Norman quarenteine, from the French quarenteine, from the Italian quarantina, a variant of quarantena, originally from the upper
Italian (Venetian) dialect as quaranta
giorni (space of forty days, group of forty), from quaranta (forty) from the Medieval Latin quarentīna (period of forty days; Lent), from the Classical Latin quadrāgintā (four tens, forty) and
related to quattuor (four), from the
primitive Indo-European root kwetwer
(four). The difference between
quarantine and isolation is one of context; while people might for many reasons
be isolated, quarantine is a public health measure to deal with those exposed
to or at risk of having been infected by a communicable disease, the duration
of the quarantine being sufficient to ensure any risk of spreading the infection
has passed. The name is from the
Venetian policy (first enforced as the 30 day edict trentino in 1377) of keeping ships from plague-stricken countries
waiting off its port for forty days to ensure no latent cases remained
aboard. The extended sense of "any
period of forced isolation" dates from the 1670s. A doublet of carene and quadragene.
In the context the L'Ancien Régime (pre-revolutionary France), it was a calque of the
French quarantaine, following the edicts
of Louis IX (and formalized by the quarantaine
du Roi (1704) of Louis XIV which was a mechanism of quieting squabbling
nobles). Quarantine was introduced to
international relations as a euphemism for "blockade" in 1937 because
the Roosevelt administration was (1) conscious of public reaction to the
effects on civilians of the Royal Navy’s blockade of Imperial Germany during
World War I (1914-1918) and (2) legal advice that a “blockade” of a non-belligerent
was, under international law, probably an act of war. The use was revived by the Kennedy administration
during the Cuban Missile Crisis (October 1962).
The verb meaning "put under quarantine" came quickly to be
used in any sense including figuratively (to isolate, as by authority) dates
from 1804. Predating the use in public
health, in early sixteenth century English common law, the quarentine was the period of 40 days during which a widow was
entitled to remain in her dead husband's home while any dower is collected and
returned. The alternative spellings quarentine, quarantin, quaranteen,
quarantain, quarantaine, quarrentine, quarantene, quarentene, quarentyne,
querentyne are all obsolete except in historic references). While not of necessity entirely synonymous,
detention, sequester, separation, seclusion, segregation, sequestration,
lazaretto, segregate, confine, separate, seclude, insulate, restrict, detach
& cordon, are at least vaguely similar.
Quarantine is a noun & verb, quarantiner is a noun, quarantinable is
an adjective and quarantined & quarantining are verbs & adjectives.

Bleriot traversant la Manche le 25
Juillet 1909
(Blériot crossing the English Channel on 25 July 1909), coloré à la main pochoir print (hand-coloured stencil print) by Ernest
Montaut (1879–1909). In 1909, this image
was issued as a commemorative postcard.
It’s a
modern conceit that technology now moves too fast for bureaucracy and laws to
keep pace but twas often thus. Although
as early as 1785, men had crossed the English Channel by hot-air balloon, for
thousands of years since the retreat of the glaciers, most arriving in British
Isles had travelled across the seas so by 1909 the British had never troubled
to update the forms used by their customs officials. So, when French engineer
and pioneer aviator Louis Blériot (1872–1936) on 25 July 1909 flew across the
English Channel in his Type XI monoplane (a flight duration of some 37 minutes),
the Collector of Customs at Dover noted in his daily log: “I issued to him a Quarantine Certificate,
thereby treating it [the aircraft] as a yacht and the aviator as Master and
owner.”
In scripture, the number 40 often occurs although
Biblical scholars, always anxious to dismiss musings from numerologists, new
age practitioners and crystal-wearing basket weavers, reject the notion it has
any special meaning beyond the idea of a “period of trial or struggle”,
memorably expressed in the phrase “forty days and forty nights”. In the Old Testament, when God destroyed the
earth in the Great Flood, he delivered rain for 40 days and 40 nights (Genesis
7:12). After killing the Egyptian, Moses
fled to Midian where he spent 40 years in the desert tending flocks (Acts 7:30)
and subsequently he stood on Mount Sinai for 40 days and 40 nights (Exodus
24:18) and then interceded on Israel’s behalf for 40 days and 40 nights
(Deuteronomy 9:18, 25). In Deuteronomy
25:3, the maximum number of lashes a man could receive as punishment for a
crime was set at 40. The Israelite spies
took 40 days to spy out Canaan (Numbers 13:25), the Israelites wandered for 40
years (Deuteronomy 8:2-5) and before Samson’s deliverance, Israel served the
Philistines for 40 years (Judges 13:1). Goliath
taunted Saul’s army for 40 days before David arrived to slay him (1 Samuel
17:16) and when Elijah fled from Jezebel, he traveled 40 days and 40 nights to
Mt. Horeb (1 Kings 19:8). The number 40
also appears in the prophecies of Ezekiel (4:6; 29:11-13) and Jonah (3:4). In the New Testament, the quarentyne was the desert in which
Christ fasted and was tempted for for 40 days and 40 nights (Matthew 4:2) and
there were 40 days between Jesus’ resurrection and ascension (Acts 1:3). Presumably, this influenced Western medicine because
it was long (and still by some) recommended that women should for 40 days rest
after childbirth.
Plague, the Venetians and Quarantino
The Plague of Justinian arrived in
Byzantine capital of Constantinople in 541, brought from recently conquered
Egypt across the Mediterranean by plague-ridden fleas in the fur of rats on
ships bringing loot from the war. From
the imperial capital it spread across Europe, Asia, North Africa and Arabia,
killing an estimated thirty to fifty million, perhaps a quarter the inhabitants
of the eastern Mediterranean. Plague never
really went away, localized outbreaks happening periodically unit it returned as
a pandemic some eight-hundred years later; the Black Death, which hit Europe in
1347, claimed some two-hundred million in just four years and demographically,
Europe would not for centuries recover from the Black Death.

There was at the time little scientific
understanding of contagion but it became clear it was related to proximity so
officials in Venetian-controlled port city of Ragusa (now Dubrovnik in Croatia)
resolved to keep newly arrived sailors in isolation until it was apparent they
were healthy. Initially, the sailors
were confined to their ships for thirty days, formalized in a 1377 Venetian law
as a trentino (thirty days), which
radically reduced the transmission rate and by 1448, the Venetians had
increased the forced isolation to forty days (quarantine), which, given
bubonic plague’s thirty-seven day cycle from infection to death, was an example
of a practical scientific experiment.
The word soon entered Middle English as quarantine (already in use in
common law as a measure of certain rights accruing to a widow), the origin of
the modern word and practice of quarantine.
The English had many opportunities to practice quarentine. In the
three-hundred odd years between 1348 and 1665, London suffered some forty
outbreaks, about once a generation (or every twenty years), the significance of
this pattern something which modern epidemiologists would later understand. Quarentine
laws were introduced in the early sixteenth century and proved effective,
reducing the historic medieval death-rates to about twenty percent.
Eggs à la Lohan
During the Covid-19 pandemic, some turned back to neglected hobbies. One of Lindsay Lohan's recommendations for a time of quarantine was to take the time to cook, posting a photograph of Eggs à la Lohan, a tasty looking omelet, inspired apparently by a widely shared motivational poem by Kitty O’Meara (on the internet dubbed the "poet laureate of the pandemic") which included the lines: And the people stayed home. And read books, and listened, and rested, and exercised, and made art, and played games, and learned new ways of being, and were still. And listened more deeply. Some meditated, some prayed, some danced. Some met their shadows. And the people began to think differently.
And the people healed. And, in the absence of people living in ignorant, dangerous, mindless, and heartless ways, the earth began to heal. And when the danger passed, and the people joined together again, they grieved their losses, and made new choices, and dreamed new images, and created new ways to live and heal the earth fully, as they had been healed.
Unfortunately, viewed from early 2023, it would seem Ms O'Meara's hopes quarantine might have left us kinder, gentler and more thoughtful may not have been realized. It may be Mr Putin didn’t read the poem and just ate his omelet.
