Themis is an ancient Greek god, one of the titans and the personification of law and order.
The second wife of Zeus, according to the account in the Theogony of Hesiod, was Themis (“Justice”), and, as we have pointed out elsewhere, she is a form of the great earth goddess. Her primary role apparently was that of controlling the cycle of the seasons, and so regularly did she bring about the periods of productiveness that men came to look upon her as a power to whom they could appeal for the elucidation of matters in which human arbiters failed. In brief, she became an oracular goddess, and the righteousness of her deliverances established her as the personification of justice and equity
