LILYBÆUM (anc. geogr.), a city of Sicily, situated on the most westerly promontory of the island of Sicily, and said to have been founded by the Carthaginians on their expulsion from Motya by Dionysius tyrant of Syracuse. It is remarkable for three sieges it sustained; one against Dionysius the tyrant, another against Pyrrhus king of Epirus, and the third against the Romans. The two first failed in their attempts, but the Romans with great difficulty made themselves master of it. No remains of this once state-

ly city are now to be seen, except some aqueducts and temples; though it was standing in Strabo's time.
