A Dictionary of Greek and Roman biography and mythology

(Ξενόδαμος,) of Cythera, a musician and lyric poet, who is mentioned by Plutarch (de Mus. 9, p. 1134b.) as one of the leaders of the second school of music, which was established at Sparta by Thaletas. Some writers ascribed to him Paeans; but others, among whom was Pratinas, said that his compositions were not Paeans, but Hyporchemes, and Plutarch adds that there was still extant in his time an ode by Xenodamus, which was manifestly a hyporcheme. Athenaeus also (i. p. 15d. e.) mentions Xenodamus and Pindar as the two chief composers of hyporchemes among the ancient lyric poets. (Fabric. Bibl. Graec. vol. ii. p. 160 ; Ulrici, Gesch. d. Hellen. Dictkunst, vol. ii. pp. 212, 223, foil., 91.)
