Mythology of the constellation Libra | Home |



In ancient times, the stars of LIBRA, The Scales, were sometimes intermingled with those of SCORPIUS by the Greeks, but they have always been considered as a separate group by the Romans. This zodiacal constellation is associated with balance - balance of both Nature and of Justice. Some 3000 years ago, the Sun entering LIBRA marked the beginning of Autumn, when days and nights were of equal length, i.e. balanced, and Roman astrologers considered that the constellation represented the scales held by Astraeia, goddess of Justice.I need help with some information about the constellation, Libra? thank you!?Alpha is known as Zubenalgenubi
