Astraea in Wikipedia

In Greek mythology, Astræa or Astrea (Ancient Greek: Ἀστραῖα;[1] English translation: "star-maiden") was a daughter of Zeus and Themis or of Eos and Astraeus. She and her mother were both personifications of justice, though Astræa was also associated with innocence and purity. She's always associated with the Greek Goddess of justice, Dike, who used to live in Earth but then left it since she was sickened by human greed. Astræa, the celestial virgin, was the last of the immortals to live with humans during the sagacious Bronze Age (the third age, after the Utopian Golden Age and defective Silver Age) in the old Greek religion's five deteriorating Ages of Man. Fleeing from the new wickedness of humanity, she ascended to heaven to become the constellation Virgo;[2] the scales of justice she carried became the nearby constellation Libra, reflected in her symbolic association with Justitia in Latin culture. In the Tarot, the 8th card, Justice, with a figure of Justitia, can thus be considered related to the figure of Astræa on historical iconographic grounds...
