Magic Squares
This is one of the earliest examples in history of a magic square,
which is a square table filled with numbers that add up to the same sum
for the columns, rows, and diagonals. This particular magic square
was seen on the back of a turtle in ancient China. "Lo Shu" means "Lo River book".
