Albrecht Dürer's Magic Square

In recreational mathematics, a magic square is a n × n square grid - where n is the number of rows (or columns) - filled with distinct positive integers in the range of [1.. n2] such that the sum of the integers in each row, column or diagonal equals a same value...

Artist Albrecht Dürer's magic square in his 1514 engraving Melencolia is believed to be the first seen in European art. I admit that I can't get my head around math but I found this interesting.
