(Γλαύκων), an Athenian mentioned by Teles (ap. Stob. Floril. vol. ii. p. 82. ed Gaisf.), who appears to have borne a distinguished part in the last struggle of the Athenians against Antigonus Gonatas, known by the name of the Chremonidean war, B. C. 263. After its termination he fled, together with Chremonides, to the court of Ptolemy Philadelphus, where he was received with great honour, and rose to a high place in the king's confidence. Droysen (Hellenism. vol. ii. p. 206) supposes him to be the same Glaucon that is mentioned by Pythermus (apud Athen. ii. p. 44) as a waterdrinker, and who is there called one of the tyrants of the Peiraeeus (ἐν τοῖς Πειραιῶς τυραννεύουσι) ; but this expression is understood by Thirlwall, with more probability, to refer to the thirty tyrants of B. C. 404. (Thirlwall's Greece, vol. viii. p. 92 not.)
