Pyrrhus had not kept Macedon long, for Lysimachus attacked him, and the fickle Macedonians all went over to the Thracian, so that he was obliged to retreat into his own kingdom of Epirus; whilst Seleucus and Lysimachus began a war, in which Lysimachus was killed; and thus both Thrace and Macedon were in the hands of Seleucus, who is therefore commonly called the Conqueror.  He was the last survivor of all Alexander’s generals, and held all his empire except Egypt; but while taking possession of Macedonia he was murdered by a vile Egyptian Greek, whom he had befriended, named Ptolemy Keraunus.  This man, in the confusion that followed, managed to make himself king of Macedon.
