TheSator Square (orRotas-Sator Square orTemplar Magic Square) is a two-dimensionalacrostic class ofword square containing a five-wordLatinpalindrome.[1] The earliest squares were found at Roman-era sites, all in ROTAS form (where the top line is "ROTAS", not "SATOR"), with the earliest discovery atPompeii (and also likely pre-AD 62).[a] The earliest square with Christian-associated imagery dates from the sixth century.[b] By theMiddle Ages, Sator squares existed inEurope,Asia Minor, andNorth Africa.[1][2] In 2022, theEncyclopedia Britannica called it "the most familiar lettered square in the Western world".[3]
A significant volume of academic research has been published on the square, but after more than a century, there is no consensus on its origin and meaning.[1][4][5] The emergence of the "Paternoster theory" in 1926 led to a brief consensus among academics that the square was created by early Christians, but the subsequent discoveries at Pompeii led many academics to believe that the square was more likely created as a Roman word puzzle (per theRoma-Amor puzzle), which was later adopted by Christians. This origin theory, however, fails to explain how a Roman word puzzle became such a powerful religious and magical medieval symbol. It has instead been argued that the square was created in its ROTAS form as a Jewish symbol, embedded with cryptic religious symbolism, which was later adopted in its SATOR form by Christians.[1][2][6] Other less-supported academic origin theories include aPythagorean orStoic puzzle, aGnostic orOrphic or Italian paganamulet, a crypticMithraic orSemitic numerology charm, or that it was a device for assessing wind direction.[1]
The square has long associations with magical powers throughout its history (and even up to the 19th century in North and South America), including a perceived ability to extinguish fires, particularly in Germany. The square appears in early and late medieval medical textbooks such as theTrotula, and was employed as a medieval cure for many ailments, particularly for dog bites andrabies, as well as for insanity, and relief during childbirth.[1][2]
It has featured in a diverse range of contemporary artworks including fiction books, paintings, musical scores, and films,[5] and most notably inChristopher Nolan's 2020 filmTenet.[7] In 2020,The Daily Telegraph called it "one of the closest things the classical world had to ameme".[8]
The Sator square is arranged as a 5 × 5 grid consisting of five 5-letter words, thus totaling 25 characters. It uses 8 different Latin letters: 5 consonants (S, T, R, P, N) and 3 vowels (A, E, O). In some versions, the vertical and horizontal lines of the grid are also drawn, but in many cases, there are no such lines. The square is described as a two-dimensionalpalindrome, orword square, which is a particular class of adouble acrostic.[3][9]
The square comes in two forms: ROTAS (left, below), and SATOR (right, below):[2][6]
R O T A S | S A T O R |
The earliest Roman-era versions of the square have the word ROTAS as the top line (called a ROTAS-form square, left above), but the inverted version with SATOR in the top line became more dominant from early medieval times (called a SATOR-form square, right above).[1] Some academics call it a Rotas-Sator Square,[2][6] and some of them refer to the object as arebus,[1][10] or amagic square.[2] Since medieval times, it has also been known as a Templar Magic Square.[1][11]

The existence of the square was long recognized from early medieval times, and various examples have been found in Europe,Asia Minor,North Africa (in mainlyCoptic settlements), and the Americas.[1][10] Medieval examples of the square in SATOR form abound, including the earliest French example in aCarolingianBible from AD 822 at the monastery ofSaint-Germain-des-Prés. Many medieval European churches and castles have Sator square inscriptions.[1][10]
The first recognized serious academic study of the Sator square is the 1881 publication ofReinhold Köhler's [de] historical survey inZeitschrift für Ethnologie [de], which was titled "Sator-Arepo-Formel". Since then, a considerable body of academic research has been published on the topic.[1][10]
Until the 1930s, a Coptic papyrus with the square in the ROTAS form dating from the fourth or fifth century AD was considered the earliest version.[b][10][13] In 1889, Britishancient historianFrancis Haverfield identified the 1868 discovery of a Sator square found in ROTAS form scratched on a plaster wall in the Roman settlement ofCorinium atCirencester to be of Roman origin; however, his assertion was discounted at the time by most academics, who considered the square to be an "early medieval charm".[1][14]
Haverfield was ultimately proved right by the 1931–32 excavations atDura-Europos inSyria that uncovered three separate Sator square inscriptions, all in ROTAS form, on the interior walls of a Roman military office (and a fourth a year later) that were dated from circa AD 200.[1][15]
In 1936, Italian archaeologistMatteo Della Corte [it] discovered a Sator square, also in ROTAS form, inscribed on a column in thePalestra Grande [it] (the gymnasium) near theAmphitheatre of Pompeii (CIL IV 8623).[16] This discovery led Della Corte to reexamine a fragment of a square, again also in ROTAS form, that he had made in 1925 at the house of Publius Paquius Proculus, also at Pompeii (CIL IV 8123). The square at the house of Publius Paquius Proculus was dated between AD 50 and AD 79 (based on the decorative style of the interior), and the palestra square find was dated pre-AD 62 (and therefore theearthquake of AD 62),[a] making it the oldest known Sator square discovery to date.[1][10]
The words are in Latin, and the following translations are known by scholars:[2][6]
The most direct sentence translation is: "The sower (or, farmer) Arepo holds the wheels with care (or, with care the wheels)".[1][10][14][4][17] Similar translations include: "The farmer Arepo works his wheels",[18] or "Arepo the sower (sator) guides (tenet) the wheel (rotas) with skill (opera)".[19]
Some academics, such as French historianJules Quicherat,[10] believe the square should be read in aboustrophedon style (i.e. in alternating directions).[20] The boustrophedon style, which in Greek means "as the ox plows", emphasizes the agricultural aspect of the text of the square.[1] Such a reading when applied to the SATOR-form square, and repeating the central word TENET, gives SATOR OPERA TENET – TENET OPERA SATOR, which has been very loosely interpreted as: "as ye sow, so shall ye reap",[10] while some believe the square should be read as just three words – SATOR OPERA TENET, which they loosely translate as: "The Creator (the author of all things) maintains his works"; both of which could imply Graeco-RomanStoic and/orPythagorean origins.[1][5]
British academic Duncan Fishwick observes that the translation from the boustrophedon approach fails when applied to a ROTAS-form square;[10] however, Belgian scholarPaul Grosjean reversed the boustrophedon rule on the ROTAS form (i.e. starting on the right-hand side instead of the left) to get SAT ORARE POTEN, which loosely translates into the Jewish call to prayer, "are you able to pray enough?".[1][10]
The word AREPO is ahapax legomenon, appearing nowhere else in attested Latin literature. Some academics believe it is likely a proper name, or possibly atheophoric name, that was adapted from a non-Latin word or was invented specifically for the Sator square.[10] French historianJerome Carcopino believed that it came from theGaulish word for a 'plough'; however, this has been discounted by other academics.[c][10] American ancient legal historianDavid Daube believed that AREPO represented aHebrew orAramaic rendition of the ancient Greek foralpha (Ἄλφα) andomega (ω), bespeaking the "Alpha-Omega" concept (cf.Isiah 44.6, andRevelation 1:8) from early Judeo-Christianity.[1]J. Gwyn Griffiths contended that the term AREPO came, viaAlexandria, from the attested Egyptian name "Hr-Hp" (ḥrḥp), which he took to mean "the face ofApis".[1][21] In 1983, Serbian-American scholarMiroslav Marcovich proposed the term AREPO as a Latinized abbreviation ofHarpocrates (or "Horus-the-child"), god of the rising sun, also calledΓεωργός `Aρπον, which Marcovich suggests corresponds to SATOR AREPO. This would translate the square as: "The sower Horus/Harpocrates keeps in check toils and tortures".[1][22][5]
Duncan Fishwick, among other academics, believed that AREPO was simply a residual word that was required to complete what is a complex and sophisticated palindrome (which Fishwick believed was embedded with hidden Jewish symbolism, per the "Jewish Symbol" origin theory below), and to expect more from the word was unreasonable from its likely Jewish creators.[2]
Attempts have been made to discover "hidden meanings" by theanagrammatic method of rearranging the letters of which the square is composed.[1]
The origin and meaning of the square has eluded a definitive academic consensus even after more than a century of study.[6][4][5] In 1938, British classical historian Donald Atkinson said the square occupied the "mysterious region where religion, superstition, and magic meet, where words, numbers, and letters are believed, if properly combined, to exert power over the processes of nature ...".[13] Even by 2003, American academic Rose Mary Sheldon called it "one of the oldest unsolved word puzzles in the world".[1] In 2018, American ancient classical historian Megan O'Donald still noted that "most interpretations of the ROTAS square have failed to gain consensus due to failings", and, in particular, reconciling the archeological evidence with the square's later adoption as a religious and magical object.[23]
Irrespective of the theory of its origin, the evidence that the Sator square, particularly in its SATOR form, became adopted into Christian imagery is not disputed by academics.[1][2] Academics note the repeated association of Christ with the "sower" (or SATOR),[1] and the words of the Sator square have been discovered in Christian settings even in very early medieval times, including:
The Sator square appears in diverse Christian communities, such as inAbyssinia where in theEthiopian Book of the Dead, the individual nails in Christ's cross were called: Sador, Alador, Danet, Adera, Rodas.[1] These are likely derived from even earlierCoptic Christian works that also ascribe the wounds of Christ and the nails of the cross with names that resemble the five words from the square.[1]
While there is little doubt among academics that Christians adopted the square, it was not clear that they had originated the symbol.[1][14]
During 1924 to 1926, three people separately discovered,[d] or rediscovered, that the square could be used to write the name of theLord's Prayer, the "Paternoster", twice and intersecting in a cross form (see image opposite). The remaining residual letters (twoAs and twoOs) could be placed in the four quadrants of the cross and would represent theAlpha and Omega that are established inChristian symbolism.[2][18] The positioning of theAs andOs was further supported by the fact that the position of theTs in the Sator square formed the points of a cross – there are obscure references in theEpistle of Barnabas toT being a symbol of the cross – and that theAs andOs also lay in the four quadrants of this cross.[10] At the time of this discovery, the earliest known Sator square was from the fourth century,[b][1] further supporting the dating of the Christian symbolism inherent in the Paternoster theory.[2] Academics considered the Christian origins of the square to be largely resolved.[1][14][2][6][15]
With the subsequent discovery of Sator squares at Pompeii, dating pre-79 AD,[a] the Paternoster theory began to lose support, even among notable supporters such as French historianGuillaume de Jerphanion.[10][15] Jerphanion noted that (1) it was improbable that many Christians were present at Pompeii, (2)first-century Christians would have written the square in Greek and not Latin, (3) the Christian concepts of Alpha and Omega only appear after the first century, (4) thesymbol of the cross only appears from about AD 130–131, and (5) cryptic Christian symbols only appeared during thepersecutions of the third century.[1][10][15]
Jérôme Carcopino claimed the Pompeii squares were added at a later date by looters. The lack of any disturbance to the volcanic deposits at the palestra, however, meant that this was unlikely,[10][14][15] and the Paternoster theory as a proof of Christian origination lost much of its academic support.[1][10][6][15][24]
Regardless of its Christian origins, many academics considered the Paternoster discovery as being a random occurrence to be mathematically impossible.[13] Several examined this mathematical probability including German historianFriedrich Focke [de] and British historianHugh Last, but without reaching a conclusion.[1] A 1987 computer analysis by William Baines derived a number of "pseudo-Christian formulae" from the square but Baines concluded it proved nothing.[6]
There is considerable contemporary academic support for the theory that the square originated as a Roman-era word puzzle.[1][6][23] Italian historianArsenio Frugoni found it written in the margin of theCarme delle scolte modenesi beside the Roma-Amor palindrome,[1] and Italian classicistMargherita Guarducci noted it was similar to the ROMA OLIM MILO AMOR two-dimensional acrostic word puzzle that was also found at Pompeii (seeWiktionary for details on the Pompeiian graffito), and at Ostia and Bolonia.[1] Similarly, another ROTAS-form square scratched into a Roman-era wall in the basement of theBasilica di Santa Maria Maggiore was found alongside the Roma-Amor, and the Roma-Summus-Amor, palindromes.[26] Duncan Fishwick noted the "composition of palindromes was, in fact, a pastime of Roman landed gentry".[10] American classicalepigraphist Rebecca Benefiel noted that by 2012, Pompeii had yielded more than 13,000 separate inscriptions and that the house of Publius Paquius Proculus (where a square was found) had more than 70 pieces of graffiti alone.[4]
A 1969 computer study by Charles Douglas Gunn started with a Roma-Amor square and found 2,264 better versions, of which he considered the Sator square to be the best.[1] The square's origin as a word puzzle solved the problem of AREPO (a word that appears nowhere else in classical writing), as being a necessary component to complete the palindrome.[23]
Fishwick still considered this interpretation unproven and clarified that the apparent discovery of the Roma-Amor palindrome written beside the 1954 discovery of a square on a tile at Aquincum was incorrectly translated (if anything it supported the square as a charm).[10] Fishwick, and others, consider the key failing of the Roman puzzle theory of origin is the lack of any explanation as to why the square would later become so strongly associated with Christianity, and with being a medieval charm.[10][23][15] Some argue that this can be bridged if considered as aPythagorean-Stoic puzzle creation.[1][5]
In 2018, Megan O'Donnell argued that the square is less of a pure word puzzle but more a piece of Latin Romangraffito that should be readfiguratively as a wheel (i.e. the ROTAS), and that the textual-visual interplay had parallels with other forms of graffito found in Pompeii, some of which later became adopted as charms.[23]
Some prominent academics, including British-Canadian ancient Roman scholar Duncan Fishwick,[2] American ancient legal historianDavid Daube,[1] and British ancient historianMary Beard,[27] consider the square as being likely of Jewish origin.[1]
Fishwick notes that the failings of the Paternoster theory (above) are resolved when looked at from a Jewish perspective.[2] Large numbers of Latin-speaking Jews had been settled in Pompeii, and their affinity for cryptic and mystical word symbols was well known.[2][10] The Alpha and Omega concept appears much earlier in Judaism (Ex. 3.14; Is. 41.4, and44.6), and the letters "aleph" and "tau" are used in theTalmud as symbols of totality.[2][10] TheTs of TENET may be explained not as Christian crosses, but as a Latin form of the Jewish "tau" salvation symbol (from Ezekiel), and its archaic form (+ or X) appears regularly onossuaries of bothHellenistic and early Roman times.[2][10] Fishwick highlights the central position of the letterN, as Jews attached significance to the utterance of the "Name" (or nomen).[2][10]
In addition, Fishwick believes a Jewish origin provides a satisfactory explanation for the Paternoster cross (or X) as the configuration is an archaic Jewish "tau" (+ or X).[2][10] Fishwick draws attention to some liturgical prayers in Judaism, where several prayers refer to "Our Father".[2][10] None of these liturgical prayers, however, can be dated to beforeJesus.[28][29] Fishwick concludes that the translations of the words ROTAS OPERA TENET AREPO SATOR are irrelevant, except to the extent that they make some sense and thereby hide a Jewish cryptic charm, and to require them to mean more is "to expect the impossible".[2][10] The motivation for the creation square might have been the Jewishpogroms of AD 19 or AD 49; however, it fell into disuse only to be revived later by Christians facing their own persecution, and who appreciated its hidden Paternoster and Alpha and Omega symbolism, but who focused on the SATOR form (which emphasized the "sower", which was associated with Christ).[2]
Research in 2006 by French classical scholar Nicolas Vinel drew on recent discoveries on the mathematics of ancient magic squares to propose that the square was a "Jewish cryptogram using Pythagorean arithmetic".[25] Vinel decoded several Jewish concepts in the square, including the reason for AREPO, and was able to explain the word SAUTRAN that appears beside the square that was discovered on the palestra column in Pompeii.[25] Vinel addressed a criticism of the Jewish origin theory – why would the Jews have then abandoned the symbol? – by noting the Greek texts that they also abandoned (e.g. theSeptuagint) in favor of Hebrew versions.[25]
The amount of academic research published on the Rotas-Sator square is regarded as being considerable (and even described by one source as "immense");[4] American academicRose Mary Sheldon attempted to catalog and review the most prominent works in a 2003 paper published inCryptologia.[1] Among the more diverse but less supported theories Sheldon recorded were:
In 2003,Rose Mary Sheldon noted: "Long after the fall of Rome, and long after the general public had forgotten about classical word games, the square survived among people who might not even read Latin. They continued to use it as a charm against illness, evil and bad luck. By the end of the Middle Ages, the 'prophylactic magic' of the square was firmly established in the superstition of Italy, Serbia, Germany, and Iceland, and eventually even crossed to North America".[1] The square appears in versions of several popular magical manuscripts from the early and late Middle Ages, magical text such as theTabula Smaragdina and theClavicula Salomonis.[32]
In Germany in the Middle Ages, the square was inscribed on disks that were then thrown into fires to extinguish them.[1] An edict in 1743 byDuke Ernest Auguste of Saxe-Weimar-Eisenach required all settlements to make Sator square disks to combat fires.[1] By the fifteenth century the square was being used as a touchstone against fire at theChâteau de Chinon andChâteau de Jarnac [fr] in France.[10]
The square appears as a remedy during labour in the twelfth-century Latin medical text theTrotula,[33] and was widely cited as a cure for dog bites andrabies in medieval Europe;[1] in both cases, the remedy/cure is administered by eating bread inscribed with the words of the square.[1][33] By the sixteenth century, the use of the square to cure insanity and fever was being documented in books such asDe Varia Quercus Historia (1555) by Jean du Choul, andDe Rerum Varietate (1557) byGerolamo Cardano. Jean du Choul describes a case where a person fromLyon recovered from insanity after eating three crusts of bread inscribed with the square.[10] After the meal, the person then recited five paternosters for the five wounds of Christ, linking to the Christian imagery believed encoded into the square.[10]
Scholars have found medieval Sator-based charms, remedies, and cures, for a diverse range of applications from childbirth, to toothaches, to love potions, to ways of warding off evil spells, and even to determine whether someone was a witch.[1]Richard Cavendish notes a medieval manuscript in theBodleian says: "Write these [five sator] words on in parchment with the blood of a Culver [pigeon] and bear it in thy left hand and ask what thou wilt and thou shalt have it. fiat."[35] Other examples include Bosnia, where the square was used as a remedy foraquaphobia, and in Iceland, it was etched into the fingernails to curejaundice.[1]
There are examples from the nineteenth century in South America, where the Sator square was used as a cure for dog bites and snake-bites in Brazil,[1] and in enclaves of German settlers (ormountain whites) in theAllegheny Mountains who used the square to prevent fire, stop fits, and prevent miscarriages.[1] The Sator square features in eighteenth-century books onPow-wow folk medicine of thePennsylvania Dutch, such asThe Long Lost Friend (see image).[34]

The Sator square has inspired many works in the arts, including some classical and contemporary composers such as works by Austrian composerAnton Webern and Italian composerFabio Mengozzi,[39] writers such as Brazilian writerOsman Lins (whose novelAvalovara (1973) follows the structure of the square), and painters such as American artistDick Higgins withLa Melancolia (1983),[5] and American artistGary Stephan withSator Arepo Tenet Opera Rotas (1982).[40]
DirectorChristopher Nolan's 2020 filmTenet has a story structure that mimics the square's concept of interlinked multiple directions of meaning, and incorporates all five of the names from the Sator square:[7]
American authorLawrence Watt-Evans notes thatSir Terry Pratchett named the main square in the fictional city ofAnkh-Morpork "Sator Square", in a reference to the symbol. Watt-Evans notes that theDiscworld series is full of other incidental references to unusual symbols and concepts.[41]

It is much more likely that we are dealing with a Latin-speaking Jewish slogan here, and there is plenty of evidence for Jews in the Vesuvian towns (including a kosher version of garum, the Roman staple of rotten fish sauce). "Alpha" and "omega" are well known in Jewish literature, and "our father" is perfectly compatible with a Jewish cultural background (and are found as that in Jewish prayers).
