In Greek mythology, Soter (Σωτήρ "Saviour, Deliverer") was the personification or daimon of safety, preservation and deliverance from harm. Suidas makes him the brother and husband of Praxidike and by her the father of Ktesios, Arete and Homonoia. (Note that both Soter and Ktesios were also cult titles of Zeus). In the Orphic Hymns Praxidike was identified with Persephone, Soter with Zeus, and their daughters Praxidikai with the Erinyes. Aeschylus references Soter as the husband of Peitharchia and father of Eupraxia.
Soteria (Σωτηρία), personification of the abstract concept of safety and salvation, was also worshipped by the Greeks. She had a sanctuary in Patrae, which was believed to have been founded by Eurypylos of Thessaly.
