In mathematics, especially historical and recreational mathematics, a square array of numbers, usually positive integers, is called a magic square if the sums of the numbers in each row, each column, and both main diagonals are the same. There is only one 3 by 3 magic square up to rotation, but henceforth the number of possible squares grows rapidly (880 for 4x4, 275305224 for 5x5, 17753889197660635632 for 6x6)
I am fairly learned in the mathematical arts, and once an Islamic Sufi friend of mine asked me if I knew anything about Magic Squares. In Islamic magic, magic squares were apparently constructed in magical spells, in conjunction with other things. He told me that he wanted to use magic squares so that he could frighten his enemies by magically rearranging their furniture while they slept.
