An illustration from Urania's Mirror (1825) depicting the constellation Libra. This faint constellation, which has no first magnitude stars, is located between Virgo to the west and Scorpius to the east. Both Roman and Babylonian astronomy likened the constellation to a pair of scales, though the Ancient Greeks held it to be the scorpion's claws. Libra is one of the constellations of the zodiac; in Western astrology, Libra covers the period between September 22 and October 21.Illustration: Sidney Hall; restoration: Adam Cuerden
