Praxiphanes, *Peripatetic philosopher (end of 4th–mid-3rd cent. bce). Probably he was born in *Mytilene and worked in *Rhodes. At some time he was publicly honoured in *Delos (IG 11. 613). The few traces of his work remaining suggest that he concentrated on grammatikē (grammar) and literary criticism. He was involved in controversy with the Epicurean *Carneiscus on the subject of friendship, and also with *Callimachus (3), who wrote a book Against Praxiphanes.
