(Λυκολέων), an Athenian orator, and a disciple of Isocrates, is mentioned only by Aristotle (Aristot. Rh. 3.10), who quotes a fragment of an oration of his ὑπὲρ Χαβρίον. As in that fragment mention is made of the bronze statue which was erected to Chabrias (Diod. 15.33; Nep. Chab. 1), it is evident that that oration must have been delivered after the year B. C. 377.
