Seleucus was another of the generals of Alexander--the only one, in fact, besides Lysimachus, who now survived. He had, of course, like Lysimachus, attained to a very advanced period of life, being at this time more than seventy-five years old. These veterans might have been supposed to have lived long enough to have laid aside their ancient rivalries, and to have been willing to spend their few remaining years in peace. But it was far otherwise in fact. Seleucus was pleased with the pretext afforded him, by the coming of Lysandra, for embarking in new wars. Lysandra was, in a short time, followed in her flight by many of the nobles and chieftains of Macedon, who had espoused her cause. Lysimachus, in fact, had driven them away by the severe measures which he had adopted against them. These men assembled at the court of Seleucus, and there, with Lysander and Ptolemy Ceraunus, they began to form plans for invading the dominions of Lysimachus, and avenging the cruel death of Agathocles. Seleucus was very easily induced to enter into these plans, and war was declared. Lysimachus did not wait for his enemies to invade his dominions; he organized an army, crossed the Hellespont, and marched to meet Seleucus in Asia Minor. The armies met in Phrygia. A desperate battle was fought. Lysimachus was conquered and slain. Seleucus now determined to cross the Hellespont himself, and, advancing into Thrace and Macedon, to annex those kingdoms to his own domains. Ptolemy Ceraunus accompanied him. This Ptolemy, it will be recollected, was the son of Ptolemy, king of Egypt, by his wife Eurydice; and, at first view, it might seem that he could have no claim whatever himself to the crown of Macedon. But Eurydice, his mother, was the daughter of Antipater, the general to whom Macedon had been assigned on the original division of the empire after Alexander's death. Antipater had reigned over the kingdom for a long time with great splendor and renown, and his name and memory were still held in great veneration by all the Macedonians. Ptolemy Ceraunus began to conceive, therefore, that he was entitled to succeed to the kingdom as the grandson and heir of the monarch who was Alexander's immediate successor, and whose claims were consequently, as he contended, entitled to take precedence of all others.
