Themis — Titan goddess
Themis was one of the Titans, daughter of Uranus and Gaea.
Themis was the Titan goddess of divine law and order--the traditional rules of conduct first established by the gods. She was also a prophetic goddess who presided over the most ancient oracles, including Delphoi (Delphi).
Themis' Name and Role
She was the human-like representation of the natural and moral order. The name derives from the Greek word meaning that which is current and contemporary. According to Hesiod, she was the second wife of Zeus, a marriage that helped the supreme Olympian to stabilise his power over all gods and humans.
Themis' three subsistences
Themis had three subsistences; goddess of natural order, which manifested through the Hores (the Hours), meaning the seasonal and never-ceasing rotation of time; goddess of moral order, manifested through Eunomia (fair order), Deke (trial) and Erene (peace), which were the utmost characteristics of the society, and through the Moires, which represented the destiny of every human being; and finally, goddess of prophecy, shown through the Nymphs, as well as the virgin Astraea.
Themis in Delphi
Initially, Themis substituted her mother in the Oracle of Delphi, having inherited the ability to foresee events from her; however, when Apollo was born, Themis cared so much for him that she eventually offered the Oracle to him.
