Philitas of Cos (/fɪˈlaɪtəs/; Greek: Φιλίτας ὁ Κῷος, Philitas ho Kōos; c. 340 – c. 285 BC), sometimes spelled Philetas (/faɪˈliːtəs/; Φιλήτας, Philētas; see Bibliography below), was a Greek scholar, poet and grammarian during the early Hellenistic period of ancient Greece. He is regarded as the founder of the Hellenistic school of poetry, which flourished in Alexandria after about 323 BC. Philitas is also reputed to have been the tutor of Ptolemy II Philadelphus and the poet Theocritus. He was thin and frail; Athenaeus later caricatured him as an academic so consumed by his studies that he wasted away and died.
Philitas was the first major Greek writer who was both a scholar and a poet. His reputation continued for centuries, based on both his pioneering study of words and his verse in elegiac meter. His vocabulary Disorderly Words described the meanings of rare literary words, including those used by Homer. His poetry, notably his elegiac poem Demeter, was highly respected by later ancient poets. However, almost all his work has since been lost.
