QUADRATO MAGICO

Il quadrato del Sator è una ricorrente iscrizione latina, in forma di quadrato magico, composta dalle cinque seguenti parole: SATOR, AREPO, TENET, OPERA, ROTAS. La loro giustapposizione, nell'ordine indicato, dà luogo a un palindromo, vale a dire una frase che rimane identica se letta da sinistra a destra o viceversa. L'iscrizione è stata oggetto di frequenti ritrovamenti archeologici, sia in epigrafi lapidee sia in graffiti, ma il senso e il significato simbolico rimangono ancora oscuri, nonostante le numerose ipotesi formulate.

In particular, this is a square 2D palindrome, which is when a square text admits four symmetries: identity, two diagonal reflections, and 180 degree rotation. As can be seen, the text may be read top-to-bottom, bottom-to-top, left-to-right, or right-to-left; and it may be rotated 180 degrees and still be read in all those ways.

The Sator Square is the earliest dateable 2D palindrome. It was found in the ruins of Pompeii, at Herculaneum, a city buried in the ash of Mount Vesuvius. It consists of a sentence written in Latin: "Sator Arepo Tenet Opera Rotas." Its translation has been the subject of speculation with no clear consensus; see below for details.
