The scales were first used as a symbol of Libra by the ancient Greeks. They believed that the goddess of justice, Dike, used scales to weigh the souls of the dead. If a soul was heavier than a feather, it was sent to the underworld. If it was lighter than a feather, it was sent to the Elysian Fields.
The scales have continued to be used as a symbol of Libra throughout history. In astrology, Libra is the sign of balance and harmony. People born under this sign are often fair-minded and diplomatic. They are also good at seeing both sides of an argument.
The scales are a reminder that we should always strive for justice and fairness in our lives. They are also a reminder that we should always be open-minded and willing to consider different points of view.
