Boios (Βοῖος), Latinized
Boeus, was a Greek grammarian and mythographer, remembered chiefly as the author of a lost work on the transformations of mythic figures into birds, his
Ornithogonia, which was translated into Latin by
Aemilius Macer, a friend of
Ovid, who was the author of the most familiar such collections of
metamorphoses. In the 2nd century CE,
Antoninus Liberalis gave extremely brief summaries of the contents of some of the myths collected in
Ornithogonia.
