Libra
Justice, harmony and balance have been associated with the stars of Libra since ancient times. These are the scales of the Roman goddess of justice, Astraea. The Babylonians saw them as the scales in which the souls of the dead were weighed - when the Sun moves into Libra in the Autumn, the days and nights are of equal length, and so finely balanced. The stars of Libra have also been seen as an altar or a mound, connected with the Tower of Babel. Zebeneschimali, Libra's second brightest star, is one of the only green stars in the sky which can be seen clearly with the naked eye. Libra lies between Virgo and Scorpio on the zodiac band.
