The Egyptians saw Libra as an equalizing factor of the Nile, which leveled it to the most desireable level for fertile lands and abundant crops. It was said the Scales were used to weigh the hearts of men after their deaths. Hearts on one side of the scale and a feather on the other would determine the destiny of a man in the afterworld. If the balance went over to the feather, he would be brought to the place of the gods, but if it leaned towards the man, they would be dropped to the underworld forever, never to see the light of Ra. Because of this, Egyptians portrayed Libra as a feather rather than a set of scales. They also called it the Scales of Ma'at.
