(Δοῦρις), of Samos, a descendant of Alcibiades (Plut. Alc. 32), and brother of Lynceus, lived in the reign of Ptolemy Philadelphus. The early part of his life fell in the period when the Athenians sent 2000 cleruchi to Samos, by whom the inhabitants of the island were expelled, B. C. 352. During the absence from his native country, Duris, when yet a boy, gained a victory at Olympia in boxing, for which a statue was erected to him there with an inscription. (Paus. 6.13.3.) The year of that victory is unknown, but it took place previous to the return of the Samians to their island, in B. C. 324. He must have been staying for some time at Athens, as he and his brother Lynceus are mentioned among the pupils of Theophrastus. (Athen. 4.128.) After his return to Samos, he obtained the tyranny, though it is unknown by what means and how long he maintained himself in that position. He must, however, have survived the year B. C. 281, as in one of his works (ap. Plin. Nat. 8.40) he mentioned an occurrence which belongs to that year.
