Lycias was an Athenian orator who flourished in the 4th century BCE.He assisted in the expulsion of the Thirty Tyrants, and distributed among the citizens his large fortune which the Tyrants had confiscated. When Dionysios of Syracuse sent a delegation to the Olympic games in c. 386 BC, Lysias held an oration (Olympiakos), in which he attacked Dionysius. The speech incited the listeners to such an extend, that they destroyed the tents of the Syracusan delegation.
