a Greek poet and grammarian, of the island of Cos, flourished under Philip and Alexander the Great, and was preceptor of Ptolemy Philadelphus. He was the author of some Elegies, Epigrams, and other works, which have not come down to us. He is celebrated in the poems of Ovid and Propertius, as one of the best poets of his age. Elian reports a very improbable story of him, namely, 'that his body was so slender and feeble, that he was obliged to have some lead in his pockets, to prevent him from being carried away by the wind.'
