Philitas of Cos, sometimes spelled Philetas, 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.
