“ Ion of Chios:—Writer of Dithyrambs, Tragedy, and Melic Poems. He also wrote Comedies, Inscriptions, Paeans, Hymns, Drinking-Songs, Eulogies, Elegies, and perhaps the prose-work called Presbeuticus , which some authorities consider spurious. Among other works ascribed to him are The Founding of Chios , a treatise On Cosmology , and Memoirs or Notes. He was a very famous man. He is said to have competed victoriously in Attica in the Dithyramb and Tragedy at the same time, and to have sent the Athenians a gift of Chian wine as a token of his regard.
