The Magic Square

After Lo Shu, the Scroll of the River Lo, an ancient Chinese legend

A long time ago, in ancient China, there was a huge flood of the River Lo.

The people tried to offer many sacrifices to the River God, but at no avail.

One day, a turtle with an interesting pattern on its shell emerged from the water.

A curious child noticed that there were three rows and three columns with nine cells on the turtle’s shell, and each cell had a different number of circular dots.


The child added the numbers in each of the three rows, and in each of the three column, and in each of the two diagonals, and the sum was always the same, 15.

Then he thought that this must be the magic number of sacrifices to offer to the River God.

The River God was pleased with his offering, and retreated its waters after that.
