=Lean´der.= A youth of Abydos. He was passionately in love with Hero, a young girl of Sestos. He was in the habit of swimming across the Hellespont to visit her, in doing which, on a tempestuous night, he was drowned. Lord Byron performed the same feat in 1810, an exploit which he has celebrated in verse in his occasional pieces. He expresses surprise that, as the truth of Leander's story had been questioned, no one had hitherto tested its practicability. =Le´da.= A daughter of king Thespius and Eurythemis, who married Tyndarus, king of Sparta. She is famous for her intrigue with Jupiter. She brought forth two eggs, from one of which sprang Pollux and Helena, and from the other Castor and Clytemnestra. She is said to have received the name of Nemesis after death. =Lem´ures.= The manes of the dead. The ancients supposed that after death the departed souls wandered over the world and disturbed the peace of its inhabitants. =Leon´idas.= A celebrated king of Lacedæmon who went to oppose Xerxes, king of Persia, who had invaded Greece with a vast army. A great battle was fought at Thermopylæ, the entire army of Leonidas consisting of 300 men who refused to abandon him. For a time this small army resisted the vast legions of Xerxes, till at length a traitor conducted a detachment of Persians by a secret path to the rear of Leonidas, when his soldiers were cut to pieces, one only of the 300 escaping. =Lep´idus, M. Æmil´ius.= A celebrated Roman, one of the triumvirs with Augustus and Antony. He was of an illustrious family, and, like many of his contemporaries, remarkable for ambition. He was unable to maintain his position as triumvir, and, resigning power, he sank into obscurity. =Le´the.= One of the rivers of hell, whose waters were imbibed by the souls of the dead which had been for a certain period confined in Tartarus. Those who drank of this river forgot what they had previously known. In this sense the word is constantly used by the poets. =Leucip´pus.= A celebrated philosopher of Abdera, about 428 years before Christ. He was a disciple of Zeno. His life was written by Diogenes. There were several others of the same name. =Leuc´tra.= A village in Boeotia, famous for the victory which Epaminondas, the Theban general, obtained over the superior force of Cleombrotus, king of Sparta, B.C. 371. =Licin´ius, C.= A tribune of the people, celebrated for his intrigues and ability. He was a plebeian, and was the first of that class that was raised to the office of master of the horse to the dictator. There were a number of other Romans of the same name. =Liv´ius, Ti´tus.= A native of Padua, a celebrated historian. He passed the chief part of his time at Naples and Rome, but more particularly at the court of Augustus, who liberally patronized him. The name of Livy is rendered immortal by his history of the Roman empire. The merit of this history is admitted by all, and the high rank which Livy holds amongst historians is undisputed.
