SATOR AREPO TENET OPERA ROTAS

LITThe Sator square is a 5×5 Latin word square found at Pompeii (before 79 CE) and across the Roman world. It reads the same left to right, right to left, top to bottom and bottom to top, and TENET crosses at the centre. Its meaning is debated (AREPO is otherwise unknown). Palindromes reverse into themselves; the square reverses in four directions at once.
