What does the Sator Square say?
The Sator Square sets five words of five letters in a square so that the same words appear whether it is read left to right, right to left, downwards or upwards. TENET, he holds, forms a cross through the middle. Four of the words are ordinary Latin: sator is a sower, tenet holds, opera is work or care, rotas is wheels. AREPO occurs nowhere else, and is usually taken as a made-up name.
A loose translation is the sower Arepo holds the wheels with care, but no reading has won agreement, and the square may have been valued as a clever thing before it was given any meaning. In later folk practice it was written on bread, wood or paper against fire, fever and the bite of a mad dog.

What sets Sator Square apart
The square is a perfect word square and a palindrome at once: twenty-five letters that give the same five words in four directions, with the middle word reading the same forwards and backwards. Only eight different letters are used. That mechanical perfection is the whole of its claim; the charm has no divine names, no request and no named owner. Later users added those around it, but the grid itself stayed fixed for nineteen centuries.
- Words: SATOR, AREPO, TENET, OPERA, ROTAS
- Oldest examples: two graffiti at Pompeii, made before the eruption of 79 CE
- Early order: ROTAS first in the oldest examples; SATOR first from late antiquity on
- Hidden cross: PATER NOSTER twice, crossing at N, plus two A and two O (Felix Grosser, 1926)
- Unknown word: AREPO, found in no other Latin text
Often mistaken for something else: A magic square is a grid of numbers whose rows and columns add to one sum; the Sator Square is a grid of letters whose rows and columns spell the same words.
The story behind Sator Square
The oldest examples were scratched on walls at Pompeii, so they predate the eruption of 79 CE, and they begin with ROTAS. Others come from Dura-Europos on the Euphrates and from Roman Britain at Cirencester and Manchester. In 1926 Felix Grosser showed that the letters can be rearranged as a cross reading PATER NOSTER with A and O left over, and argued for a Christian origin; the Pompeii dates make that uncertain, and the question is still open.
Why Sator Square matters
Sator Square is the best travelled written charm of Europe, found from a Roman house wall to nineteenth century American charm books, with its design unchanged.
How to read Sator Square
Historians treat it as a puzzle about who made it and why; in folk tradition it was copied out whole, since its force was thought to lie in the unbroken pattern.
Sator Square in practice: an example
A visitor to the Corinium Museum in Cirencester can see the square cut into Roman wall plaster, reading ROTAS OPERA TENET AREPO SATOR.

Common questions
What does the Sator Square say?
It reads SATOR AREPO TENET OPERA ROTAS. A rough sense is the sower Arepo holds the wheels with care, but AREPO is not a known Latin word and scholars have not agreed on a translation.
Is the Sator Square Christian?
It was certainly used by Christians later, and its letters can be arranged into a PATER NOSTER cross. Whether it began as a Christian sign is disputed, because the Pompeii examples are very early for a Christian presence there.
Where is the oldest Sator Square?
The oldest known are two examples scratched at Pompeii, buried by Vesuvius in 79 CE. Both start with the word ROTAS; the order beginning with SATOR became usual later.
