Geomantic Knight "The cyclic symbolism of the Chess board resides in the fact that it expresses the unfolding of space according to the quaternary and octonary of principle directions (4x4x4=8x8) and that it synthesizes in crystalline form, the two great complementary cycles of the sun and moon: the duodenary of the zodiac and the 28 lunar mansions; further more, the number 64, the sum of the squares on the Chess board is a submultiple of the fundamental cyclic number 25920, which measures the precession of the equinoxes - Titus Burckhardt .
