History: It is the only constellation in the sky that represents an inanimate object. For the longest time, it has been represented as a set of scales. Libra is located between Virgo and Scorpius. Early Greeks actually considered this constellation to be a part of Scorpius and that it was located where the claws would be thought to be at. Some say that the Greeks viewed it as a part of Virgo because of the goddess of justice. The Egyptians saw Libra as equalizing the Nile flood to the level most desirable for fertile lands and abundant crops. They also said that Libra was used to measure the hearts of men after death. Hearts on one side of the scales and a feather on the other determined human destiny in the afterworld.
Libra is the seventh sign of the zodiac and is ruled by the planet Venus. Libra is an air sign.
