2. CALLIAS I., son of Phaenippus and probably nephew of the above, is mentioned by Herodotus (6.121) as a strong opponent of Peisistratus, and as the only man in Athens who ventured to buy the tyrant's property on each occasion of his expulsion. On the same authority, if indeed the chapter be not an interpolation (6.122; see Larcher, ad loc.), we learn, that he spent much money in keeping horses, was a conqueror at the Olympic and Pythian games, at the former in B. C. 564 (Schol. ad Aristoph. Av. 283), and gave large dowries to his daughters, allowing them--a good and wise departure from the usual practice--to marry any of the Athenians they pleased.
