Lysimăchus in Harpers Dictionary of Classical Antiquities
（Λυσίμαχος). One of Alexander's generals, who obtained Thrace in the division of the provinces after Alexander's death (B.C. 323), and assumed the title of king in B.C. 306. He joined the other generals of Alexander in opposing Antigonus, and it was he and Seleucus who gained the decisive victory at Ipsus over Antigonus, in which the latter fell (B.C. 301). In B.C. 291 Lysimachus was taken prisoner by Dromichaetes, king of the Getae, whose country he had invaded, but he was restored to liberty by the latter. In B.C. 287 Lysimachus and Pyrrhus expelled Demetrius from Macedonia. Pyrrhus, for a time, obtained possession of the Macedonian throne; but in the following year he was driven out of the country by Lysimachus, who now became king of Macedonia. Towards the end of his reign the aged Lysimachus put to death his son Agathocles, at the instigation of his wife, Arsinoe, daughter of Ptolemy Soter. This bloody deed alienated the minds of his subjects, and Seleucus invaded the dominions of Lysimachus. The two monarchs met in the plain of Corus (Corupedion), and Lysimachus fell in the battle that ensued, B.C. 281, in his eightieth year.
