Palindrome (pronounced pal-in-drohm)
(1) A word, line, verse, number, sentence etc,
reading the same backward as forward.
(2) In biochemistry, a region of DNA in which the
sequence of nucleotides is identical with an inverted sequence in the
complementary strand.
1638: From the Ancient Greek παλίνδρομος (palindromos) (running back again; recurring, literally “literally "a running back”) the construct being πάλιν (pálin) (again, back) + δρόμος (dromos) (direction, running, race, racecourse). Pálin was from the primitive Indo-European kwle-i-, a suffixed form of the root kwel- (revolve, move round) (kw- becomes the Greek p- before some vowels. The word palindrome was first published by Henry Peacham (1578-circa 1645) in The Truth of Our Times (1638). Although derived from the Greek root palin + dromos, the Greek language uses καρκινικός (carcinic, literally “crab-like”) to refer to letter-by-letter reversible writing. The related palinal (directed or moved backward, characterized by or involving backward motion) dates from 1888. The noun palinode (poetical recantation, poem in which the poet retracts invective contained in a former satire) dates from the 1590s and was from either the sixteenth century French palinod or the Late Latin palinodia, from the Greek palinōidia (poetic retraction), again from pálin; the related form were palinodical & palinodial. The word palinode was sometimes applied to the apologies artists and others in the Soviet Union were compelled to publish, often after being accused of formalism or something just as heinous. Palindrome & palindromist are nouns, palindromically is an adverb and palindromic an adjective.
Even before he spent the final years of his political career as a senior official in the collaborationist regime of Vichy France under Marshal Philippe Pétain (1856-1951), the palindromic Laval was already notorious for his dubious financial dealings while in government and being a party to the Hoare–Laval Pact (1935), concocted with the then British Foreign Secretary Samuel “Slippery Sam” Hoare (1880-1959) with which the pair sought to end the tiresome Second Italo-Ethiopian War (the last of the colonial land-grabs in the era of European colonization) because it was “bad for business”. Something of a precursor to the 1938 Munich Agreement in which the UK and France acquiesced to the Nazi’s dismemberment of Czechoslovakia in exchange for what, delusionally, they believed would be Adolf Hitler’s (1889-1945; Führer (leader) and German head of government 1933-1945 & head of state 1934-1945) final territorial claim in Europe, what the Hoare–Laval Pact offered was a partition of Abyssinia, something which in retrospect would have been merely the first step to Benito Mussolini (1883-1945; Duce (leader) & Prime-Minister of Italy 1922-1943) absorbing the whole country as a colony of Imperial Italy. Even for the, by then jaded, people of France and the UK the cynicism was too blatant and the reaction when the details were made public ensured both ministers were dismissed.
Pétain had little faith in the arrangements his regime negotiated with the Germans honored, telling colleagues after one meeting: "It will take six weeks to work out all the details and six months for the Germans to forget all about them." Because Berlin didn't formerly created diplomatic relations with France after the defeat in 1940, Otto Abetz was never properly credentialed as ambassador but wholly he discharged the duties. His great nephew is Eric Abetz (b 1958; Liberal Party senator for Tasmania, Australia 1994-2022, Treasurer of Tasmania since 2024).
Hoare was an accomplished ice-skater and made a political comeback as did Laval who, sniffing the winds of French defeat in 1940, became a convinced fascist, serving in the Vichy regime between July 1940-August 1944 variously as vice-president of the Council of Ministers and head of government. He fled to Spain after the Liberation of France but was extradited and put on trial for plotting against the security of the state and collaborating with the Nazis; found guilty, he was executed by firing squad in October 1945. Old Marshal Pétain fared a little better. Although also sentenced to death for his role during the occupation, Charles de Gaulle (1890-1970; President of France 1959-1969), then serving as Chairman of the Provisional Government of the French Republic, couldn’t bring himself to sign the death warrant for one of the country’s heroes of World War I and commuted the sentence to life imprisonment, officially on the grounds of “age”.
Perhaps surprisingly, the longest known palindromic word is not German despite their fondness for lengthy compounds. According to the Guinness Book of World Records the record is held by the 19 character saippuakivikauppias which is Finnish for “a travelling salesman who sells lye (caustic soda)”. It’s said not often to come up in conversation and seems to exist only a curiosity used in lists of long palindromes where it's the undisputed number one. In English, palindromes of a few characters are common but examples with more than seven letters are rare. Tattarrattat (the sound made by knocking on a door), as it’s usually spelled, has 12 characters but is a bit of a fudge because it’s also an onomatopoeia so some lexicographers insist it doesn’t count. Also cheating but clever is the 11 letter aibohphobia meaning a fear of palindromes, the construct being the suffix -phobia + its reverse. Adding to the charm is that it’s doubtless a non-existent condition, but it’s suspected there are anyway a few of those in the literature of psychiatry. From India, there's kinnikinnik, a smoking mixture of bark & leaves (but no tobacco). English’s longest “real” palindrome appears to be detartrated, the past participle of detartrate (to remove tartrates (salts of tartaric acid)), especially from fruit juices and wines, in order to reduce tartness or sourness). Not only is it a real word but it describes a common process in the industrial production of foods and beverages.
On 2 February 2020, Lindsay Lohan (b 1986), in a now deleted Instagram post, for the first time publicly acknowledged her relationship with Bader Shammas (b 1987), a group photograph from Dubai, including the couple and her sister Aliana (b 1993), captioned: "@aliana lovely night with sister and my boyfriend bader💗". The couple would later marry. 2 February 2020 (02-02-2020) was the twenty-first century’s only eight-digit global palindrome (ie it works with either the MM-DD-YYYY or DD-MM-YYYY convention). The last eight-digit global palindrome happened 908 years earlier on the even more numerically symmetrical 11 November 1111 (11-11-1111) and the next one will be 908 years hence on 3 March 3030 (03-03-3030). Six and seven digit palindromes are more common.
Palindromic sentences are often created and these are judged not by length but by their elegance which is why “never odd or even” often is cited as an example. Leigh Mercer (1893–1977) was a word nerd and recreational mathematician who devised the classic "A man, a plan, a canal: Panama!" and this approach was in the 1980s taken to its logical extreme in two novels, Satire: Veritas (1980, 58,795 letters) by David Stephens and Dr Awkward & Olson in Oslo (1986, 31,954 words) by Lawrence Levine, both said to be palindromically perfect and wholly nonsensical. Shorter, but of admirable clarity, are the many baptismal fonts in Greece and Turkey which bear the circular 25-letter inscription NIYON ANOMHMATA MH MONAN OYIN (Wash (my) sins, not only (my) face). This appears also in several English churches.
Created essentially because of the inadequacies of the official justice system, they're now often referred to as "proto-vigilante" courts but for centuries they filled a niche before they came increasingly to be associated with injustice and corruption before finally being abolished in 1811, a half-decade after the dissolution of the Holy Roman Empire, the source of their original authority.
In linguistics, these “grid of letters” are called “acrostics”. Acrostic was from the Middle French acrostiche & acrostique (persisting in modern French as acrostiche) and its etymon the Late Latin acrostichis, from the Ancient Greek ἀκροστιχίς (akrostikhís), the construct being ἄκρο- (ákro-) (the prefix indicating, inter alia, the extremity or tip of something) + στῐ́χος (stĭ́khos) (row or file of soldiers; line of poetry, verse) (ultimately from the primitive Indo-European steyg- (to climb, go)). They remain still a popular form for the “word puzzles” appearing in the surviving newspapers and magazines. In verse, an acrostic is a poem in which the initial letters of each line make a word or words when read downwards (the mesostich (middle) or telestich (final) letter of each line might also be used) whereas in prose the first letter of each paragraph or sentence might make up a word. It’s speculated the earliest acrostic may have been created as a mnemonic device and used as a tool to aid oral transmission and most of the acrostics in the Old Testament are of the alphabetical or abecedarian (in this context “a work which uses words or lines in alphabetical order”) kind. For poets however it may have been just an intellectual exercise (or perhaps “a gimmick” if not well-received by certain critics). Geoffrey Chaucer (circa 1344-1400) used a simple acrostic device in ABC, a twenty-four stanza poem in which the first letter of the first word in each stanza is the appropriate letter of the alphabet, from A to Z. The dramatist Benjamin Jonson (circa 1572–circa 1637) in his Argument (prefacing The Alchemist (1610)) used an acrostic verse (“argument” a technical term meaning “the abstract” or “plot summary”).
The palindromic (or “all-round”) acrostic seen on the oath skull is known as the “Sator square” or the “Cirencester word square” because a copy was in 1868 discovered on a painted wall plaster in what is now Victoria Road in the English town of Cirencester in the Cotswold District of Gloucestershire. At the time of the inscription, during the Roman occupation of Britain, the settlement was called Corinium. The best documented of the early examples was one etched onto a wall in the doomed city of Herculaneum, the conclusion of most being Sator Arepo Tenet Opera Rotas should be understood as “The sower, Arepo, makes the wheel work”), the trick being it can be read vertically, horizontally, or in the diagonal. Known also as pentacles, the “SATOR” was the most commonly found in the Western Esotericism of late antiquity, used by Kabbalists, Gnostics, alchemists and other pre-medieval mystics in the creation of magic spells, amulets, potions etc and were thus often seen in the shops of apothecaries. For deconstructionists, the translations are:
sator:
sower/planter
tenet:
he/she/they/it holds/has/grasps/possesses
opera:
work/exertion/service
rotās:
wheels
There has been speculation about the meaning of this pentacle, some a little fanciful and it’s not impossible things were made up just to fit, rather as "the quick brown fox jumps over the lazy dog" was coined to use each letter in the alphabet and "DICK HOOD DID EXCEED" serves no purpose other than to appear the same if inverted and viewed in a looking glass.
ROTAS
OPERA
TENET
AREPO
SATOR
The one on the skull was a second form, copied from an Egyptian papyrus of the late fourth or early fifth century AD:
SATOR
AREPO
TENET
OPERA
ROTAS
Among professionals and amateurs alike, there has been much debate about the possible meaning(s) and although there are a number of permutations, most hint at something like “the sower Arepo holds the wheels carefully”, indicating the care required when sowing the seeds for next season’s crop. The form may however in some places have been vested with magical or religious significance. In sixth century Ethiopia, the five words (corrupted to Sador, Alador, Danet, Adera and Rodas), were used as the names of the five nails of Christ's Cross. In France, the word square was known to have been used as a form of lucky charm and reputedly, one fortunate inhabitant of Lyon was cured of madness by eating three crusts of bread (each inscribed with the square) while making five recitations of the Pater Noster in remembrance of the five wounds of Christ and the five nails. Presumably encouraged by such an event, Spanish and Portuguese Roman Catholic missionaries took these charms to South America where they were said variously to protect folk from snake bites and aid childbirth.
