(Ἀρίσταρχος) of TEGEA, a tragic poet at Athens, was contemporary with Euripides, and flourished about 454 B. C. He lived to the age of a hundred. Out of seventy tragedies which he exhibited, only two obtained the prize. (Suidas, s.v. Euseb. Chiron. Arnen.) Nothing remains of his works, except a few lines (Stobaeus, Tit. 63.9, tit. 120.2; Athen. 13.612f.), and the titles of three of his plays, namely, the Ἀσκληπιός, which he is said to have written and named after the god in gratitude for his recovery from illness (Suidas), the Ἀχιλλεύς, which Ennius translated into Latin (Festus, s. v. prolato aere,) and the Τάνταλος. (Stobaeus, 2.1.1.)
