Boethus
3. A Platonic philosopher and grammarian, who wrote a Lexicon to Plato's works (συναγωγὴ λέξεων Πλατωνικῶν), dedicated to Melanthus, which Photius (Phot. Bibl. 154) preferred to the similar work of Timaeus still extant. Another work on the ambiguous words of Plato (περὶ τῶν παρὰ Πλατωνι ἀπορουμένων λέξεων) was dedicated to Athenagoras. (Phot. Bibl. 155.) Whether he is the same as the Boethus who wrote an exegesis to the Phaenomena of Aratus (Geminus, Introd. ad Phaen. 14) is uncertain, and also whether he is the one against whom Porphyrius wrote his work περὶ ψυχῆς. (Euseb. Praep. Evang. 14.10, 15.11, 16; comp. Hesych. s. v. διὰ πάντων κριτής; Aeneas, Gaz. Theophr. p. 16.)
