Each of the sacred unit fractions which the ancient Egyptians attributed to the six parts of the eye of the god Horus: 1/2, 1/4, 1/8, 1/16, 1/32, and 1/64. These fractions,
all with powers of two in their denominators, were used to represent the fractions
of hekat, the unit measure of capacity for grains. According to a legend,
the pieces were lost in a battle, and restored by the god Thoth.
