LYSIM'ACHUS, b. Pella, Macedonia, about 360 B.C.; a gen. of Alexander the great, He was a pupil of the philosopher Callisthenes; and was in his youth distinguished for bravery- and physical strength. He was attacked by a HMI in the forests of Syria, which he killed without assistance, from which probably- originated the story told by Justia and Seneca of his being exposed to a furious lion and killing it by thrusting his cloak into its mouth. - On the division of the empire at Alexander's death, 323, he received Thrace and the countries on the coast of the Euxine. He took possession .of Thrace after conquering Seuthes, its king, and a powerful army. In B.C. 314 Le joined the league formed against Antigonus by Ptolemy, Seleueus, aud Cassander. In 306 he assumed the title of king. In 302 he was sent into Asia Minor to attack Antigomis, subduing on his way Pbrygia, Lydia, and other places, taking possession of many strong fortresses in which Antigornis had collected immemse treasure. On the approach of Antigonus he withdrew into I3ithynia, where he was joined by Seleucus, and they, in 301, advanced against Antigonus and his son Demetrius. In 'the following year these two gens., aided by the forces of Ptolemy and Cassamlep, met Autigonus at Ipsus„
where a fierce battle was fought; Antigonus was killed, and his dominions shared by the victors, Lysimachus obtaining the .n.w. part of Asia Minor. In 292 he attacked Getre, n. of the Danube, but was defeated, made prisoner, and released on giving his daughter in marriage to the king of the Getre. In 288 he combined with Ptolemy, Seleticus, and Pyrrhus against Demetrius, who had invaded Thrace during his absence and captivity, drove him from Macedonia, became king thereof himself, and compelled Pyrrhus, who laid claims to the kingdom, to retire to his native dominions. The latter part of the life of Lysimachus was imbittered by dotnestic dissensions and intestine troubles. Having put to death his son Agathocles at the instigation of his wife, Arsmoe, the daughter of Ptoletny, king of Egypt, who feared that on the death of Lysimaelins she and her children would be put to death by Agathocles, his subjects rose in rebellion, and Seleucus, at the entreaty of the widow of Agathocles, attacked Lysimachus, who was killed on the plain of Corns.
