Themis, who has already been alluded to as the wife of Zeus, was the daughter of Cronus and Rhea, and personified those divine laws of justice and order by means of which the well-being and morality of communities are regulated. She presided over the assemblies of the people and the laws of hospitality. To her was intrusted the office of convoking the assembly of the gods, and she was also mistress of ritual and ceremony. On account of her great wisdom Zeus himself frequently sought her counsel and acted upon her advice. Themis was a prophetic divinity, and had an oracle near the river Cephissus in Bœotia.
She is usually represented as being in the full maturity of womanhood, of fair aspect, and wearing a flowing garment, which drapes her noble, majestic form; in her right hand she holds the sword of justice, and in her left the scales, which indicate the impartiality with which every cause is carefully weighed by her, her eyes being bandaged so that the personality of the individual should carry no weight with respect to the verdict.
This divinity is sometimes identified with Tyche, sometimes with Ananke.
Themis, like so many other Greek divinities, takes the place of a more ancient deity of the same name who was a daughter of Uranus and Gæa. This elder Themis inherited from her mother the gift of prophecy, and when she became merged into her younger representative she transmitted to her this prophetic power.
