The earliest known examples were found as graffiti in Pompeii , dating back to before the eruption of Mount Vesuvius in 79 AD . In these early versions, the square often began with "ROTAS" rather than "SATOR".
The Sator Square is a 5x5 Latin palindrome found in ancient ruins across Europe (Pompeii, England, Syria). It reads the same forward, backward, top to bottom, and bottom to top:
The square depicts a Creator figure (Sator) actively maintaining the machinery of the universe (Rotas) through sustaining effort (Tenet). It is an image of a God who does not just create and leave, but who holds the world together.
