The second is best aseribed to Thaletas of Gortyn, Xenodamus of Cythera, Xenocritus of Locri, Polymnastus of Colophon, and Sacadas of Argos. For we are told that the institution of the Feast of Naked Youths at Sparta, of the Provings in Arcadia, and of the Feast of Garments as it is called at Argos, was due to these musicians. Thaletas, Xenodamus, and Xenocritus were composers of Paeans, Polymnastus of the so-called Orthian or High-pitched Songs, and Sacadas of Elegies . . . Polymnastus, too, composed nomes to be sung to the flute.
