Onatas was an ancient Greek sculptor of the time of the Persian Wars and an exponent of the flourishing school of Aegina. Many of his works are mentioned by Pausanias; they included a Hermes carrying the ram, and a strange image of the Black Demeter made for the people of Phigalia; also some elaborate groups in bronze set up at Olympia and Delphi. For Hiero I, king of Syracuse, Onatas executed a votive chariot in bronze dedicated at Olympia. In Delphi he was one of the sculptors who executed the Ex voto of the Tarentines.If we compare the descriptions of the works of Onatas given us by Pausanias with the well-known pediments of Aegina at Munich we shall find so close an agreement that we may safely take the pedimental figures as an index of the style of Onatas. They are manly, vigorous, athletic, showing great knowledge of the human form, but somewhat stiff and automaton-like. His artistic style contribute to the formation of the so-called "severe" style.
Onatas has also been linked to the Riace warriors group, also attributed to Phidias. The pair were found of the coast of Reggio Calabria in 1972.
Onatas (; fl. c. 5th century BC) of Croton or Tarentum was a Pythagorean philosopher. Nothing is known about his life, but a long passage from a work entitled On God and the Divine is preserved Stobaeus. The work probably dates from the 1st century BC or AD and is part of the pseudonymous Neo-Pythagorean literature.
The author ("Pseudo-Onatas") argues that God is a governing part of the universe, although the universe itself is not God but only divine. He argued against the belief in a single deity on the basis of the many "powers" in the universe; they must belong to different gods. He also claimed that the earthy mixture of the body defiles the purity of the soul.
