Ariston of Collytus (; died c. 424 BC), was the father of the Greek philosopher
Plato (originally named Aristocles). Legend holds that he was descended from
Codrus, the ancient king of Athens.
Diogenes Laërtius on the authority of
Speusippus and others, relates a story that "Ariston made violent love to
Perictione, then in her bloom, and failed to win her; and that, when he ceased to offer violence,
Apollo appeared to him in a dream, whereupon he left her unmolested until her child was born." Ariston died when Plato was still a boy, and his mother
Perictione remarried
Pyrilampes, a friend of the Athenian politician
Pericles.
