), a son of the Athenian orator Hyperides, is said by Plutarch (Vit. x. Orat.
p. 848), who calls him a rhetor, to have written orations, one of which, viz. against Phocion, is mentioned by Plutarch himself. (Phoc.
4; comp. Athen. 13.590
; Sid. s. v. Γλαύκιππος
; Phot. Bibl. Cod.
266. p. 495, ed. Bekker.) Whether he is the same as the rhetorician Glaucippus, of whom a fragment is preserved by Seneca (Controv.
4.25), or as the Glaucippus who wrote on the Sacra of the Athenians (Macr. 1.13
), is uncertain.
