History of magic squares

Magic squares are rather old. According to legend the first known magic square was discovered by Emporor Yu in China about 2200 B.C. When he was walking on the banks of the Loh river, he saw a mystical turtle with some dots within squares on its shell.

The very first textual reference can be found, however, in the writings of Zhuang Zi (369-286 B.C.). In this representation, the odd numbers are represented by white dots (Yang symbols) and represent the sky, while the even numbers are shown as black dots (the Yin symbols), the symbol of the Earth.
