From Smith's Dictionary of Greek and Roman Biography and Mythology (London, 1880)
ABRO'NYCHUS ('Abronuchos), the son of Lysicles, an Athenian, was stationed at Thermopylae with a vessel to communicate between Leonidas and the fleet at Artemisium. He was subsequently sent as ambassador to Sparta with Themistocles and Aristeides respecting the fortifications of Athens after the Persian war. (Herod. viii. 21; Thuc. i. 91.)
