Astrognome A-Z of Constellations # 49 Libra


Libra the Scales

A small faint constellation of the zodiac, the ancient Greeks knew it as the ‘claws of the scorpion’ an extension of the neighbouring constellation of the Scorpion. However the Romans made it a separate constellation at the time of Julius Caesar. Since then the scales of Libra have come to be regarded a the symbol of justice held aloft by the goddess of justice Astraea.
