The Sator Square is a word square than contains a palindrome in Latin. It features the words SATOR AREPO TENET OPERA ROTAS arranged in a square so that they may be read top-to-bottom, bottom-to-top, left-to-right, and right-to-left. (It can even be read boustrophedon, meaning alternate lines may be read in opposite directions.) The earliest known appearance of the square was found in the ruins of Herculaneum, which was buried in AD 79 in the ash of Mt. Vesuvius.

As the Ox Turns

Higgledy-Piggledy
Sator Square palindrome
Reads all directions and
Means just the same;
Plowman Arepo can
Boustrophedonically
Turn as the ox does and
Still garner fame.
