Lysimachus had, during this period, after the murder of Antipater, his son-in-law, and the last heir of the elder Antipater (perhaps as a punishment for an attempt upon his own life), been in possession of a portion of Macedonia; but he had afterwards given it up to Demetrius. The Macedonians now recognised Pyrrhus as their king; but Lysimachus invaded his kingdom, and after having reigned alone for seven months, Pyrrhus was obliged to divide his empire between himself and Lysimachus. The Macedonians deserting him as a stranger, surrendered to Lysimachus, whom they honoured as an ancient companion of Alexander, and whom they regarded as being nearly related to themselves, being either a Thessalian or a Macedonian. The division, however, between Lysimachus and Pyrrhus did not last for any length of time; for shortly after Lysimachus drove Pyrrhus out of his kingdom. He had reigned over Macedonia altogether five years and six months, partly in conjunction with Lysimachus and partly alone.
The empire of Lysimachus had been gradually extended and consolidated. Greece did not become subject to him; Antigonus Gonatas, who had received the greater part of his father’s fleet, maintained himself there with the remnants of his father’s forces, and from Demetrias he ruled over a part of Greece, although many Greek cities asserted their independence. Besides Macedonia proper and Thrace, Lysimachus ruled over Lydia, Mysia, Ionia, Caria, and, no doubt over Phrygia Major also—an empire as beautiful as he could have wished, “and just of that extent which Alexander ought to have given to his empire in order to insure its stability.” His real residence seems to have been Lysimachia in Chersonesus, in the neighbourhood of the ancient Cardia. With the exception of Thessalonice, all those Macedonian princes built new capitals for themselves; Alexandria was at least enlarged by Ptolemy.
Previously to the conquest of Macedonia, Lysimachus had undertaken an expedition across the Danube, against Dromichætes, a king of the Getæ. In the plain of Bessarabia his retreat was cut off, and he, with all his army, was taken prisoner. The generous conduct of the Dacian king, Dromichætes, is celebrated in the collection of anecdotes; Lysimachus was set free, and his power was not weakened by this defeat.
[283-282 B.C.]
But the royal house was soon to become the scene of a terrible tragedy, the occasion of which came from the family of Ptolemy. Ptolemy had divorced his first wife Eurydice, the daughter of Antipater; and his second wife, the intriguing Berenice, employed every means to cajole Ptolemy, who was enfeebled by age, and to get the succession decided in favour of her own son. She succeeded so well that the aged Ptolemy, two years before his death, resigned his throne to his younger son Ptolemy Philadelphus, and himself took the oath of allegiance to him. The first-born Ptolemy, surnamed Ceraunus, betook himself to Lysimachus, whose eldest son, Agathocles, was married to his sister Lysandra, likewise a daughter of Ptolemy Soter, by his first wife Eurydice. Lysimachus, who received him in a friendly manner, was himself married to Arsinoe, a daughter of Ptolemy by his second wife, by whom he had two sons. This Arsinoe now had recourse to the same intrigues in the house of Lysimachus. His eldest son, Agathocles, was already a man of very mature age (Lysimachus was seventy-four years old at his death) and of great eminence. In many a campaign he had successfully commanded his father’s armies; he was very popular throughout the country, and it was he that was destined to succeed his father. But Arsinoe hated him as the husband of her half-sister, against whom she entertained a deadly enmity; and also because he was an obstacle in the way of her own children. She accordingly determined to deprive him of both his throne and his life. It must be borne in mind, that in case of Lysimachus’ death she had reason to fear for her own life, and that according to the practice of the age, the step-mother and her children would have been murdered by Agathocles as soon as he had ascended the throne.
Arsinoe, therefore, calumniously informed Lysimachus that his life was threatened by his son Agathocles. The latter was at first treated with insult and persecuted by his father, and soon afterwards killed by poison. As this made a great impression, Lysimachus caused several others of his sons to be put to death, and began to rage against all whom Arsinoe pointed out as partisans of Agathocles. These things produced a complete state of anarchy both in the house of Lysimachus and in his kingdom. As everyone felt that his life was in danger, his nobles began to apply for protection to Seleucus, to whom Lysandra, the wife of Agathocles, had fled with one of her husband’s brothers. Seleucus had no objection to being thus called upon to interfere. He marched from Babylon across Mount Taurus down into Western Asia, and, though chiefly by treachery, gained a decisive victory over the aged king in Lower Phrygia. Lysimachus, as at all other times, showed great valour, but fell in the battle. With the exception of Cassandrea, where the widow Arsinoe resided with her children, the whole of the Macedonian state surrendered to Seleucus.
SELEUCUS; ANTIGONUS; THE PTOLEMIES
The whole of Alexander’s empire, with the exception of Egypt, southern Syria, a portion of Phœnicia, and Cyprus, was thus united under the sceptre of Seleucus. As he had not seen his native country since the beginning of Alexander’s expedition, Seleucus now crossed the Hellespont to take possession of his native land, perhaps with the intention of there closing his days in peace. But while sacrificing in the neighbourhood of Lysimachia, he was murdered by Ptolemy Ceraunus, whom he had protected in his misfortunes with the view, according to the policy of the time, of having a dangerous pretender against Ptolemy Philadelphus. The state of dissolution was such that Ptolemy, without any difficulty, was recognised as king by the Macedonian troops of Seleucus, and by all Macedonia. He accordingly took possession of the empire. There was no hereditary family—that was the misfortune. Ptolemy Ceraunus had paved his way to the throne by murder and ingratitude; but he was in himself no insignificant man: he was very brave and resolute. What his morality was will be seen hereafter.
[281-280 B.C.]
The Asiatic provinces of Lysimachus were quite united with the Syrian empire, of which Antiochus remained in undisturbed possession, Seleucus, even in his lifetime, having assigned to him the upper provinces. Antiochus endeavoured to avenge the death of his father; and a war broke out between Ptolemy Ceraunus and this Antiochus, who is surnamed Soter, for all the Macedonian kings bearing the same name are distinguished by surnames. He was called Soter, for having conquered the Gauls in Asia Minor. Ptolemy Ceraunus was also at war with Antigonus.
