It seems a lot of old Latin stuff liked this Sator Square, five five-letter words that form a palindrome:
S A T O R A R E P O T E N E T O P E R A R O T A S
Was there ever a Hebrew equivalent to this? (I'm not asking if you can come up with one now; I'm asking if anything like this was found on Jewish carvings, in Ibn Ezra's riddles, or the like. Hopefully therefore on-topic as "Judaism.")
And no, I will not attempt to connect this to the Gemara where Moshe goes forward in time to R' Akiva's classroom!
