- Virgo is the second-largest constellation in the sky, exceeded only by the much fainter Hydra. The Greeks called the constellation Παρθένος (Parthenos), which is the name Ptolemy gave in the Almagest. She is usually identified as Dike, goddess of justice, who was daughter of Zeus and Themis; but she is also known as Astraea, daughter of Astraeus (father of the stars) and Eos (goddess of the dawn). Virgo is depicted with wings, reminiscent of an angel, holding an ear of wheat in her left hand (the star Spica).

In ancient Greek times, the area of sky we know as Libra was occupied by the claws of the scorpion, Scorpius. Aratus and Eratosthenes, among others, called this area Χηλαί (Chelae), literally meaning ‘claws’, an identification that lives on in the names of the individual stars of Libra (see below). As things have worked out, Libra is now a slightly larger constellation than Scorpius, but is much less conspicuous.
