The Star Gauge: an ancient Chinese palindrome that brought a husband back

In the fourth century, Su Hui's husband was stolen by a concubine.  To get him back, she composed a palindromic figure to rival the Roman Sator Square: a poem arranged from 841 characters that can be read diagonally as well as back and forth, up and down. It can be read 2,848 ways.  Naturally, he got rid of the concubine and returned to his wife.  (Who wouldn't?)  More details at my source, the blog Futility Closet.The Star Gauge
