ANTIOCHUS (the son of Seleucus and grandson of Antiochus),
king of the Syrians, the Babylonians, and other nations, was the sixth in succession from that Seleucus who succeeded Alexander in the government of the Asiatic countries around the Euphrates. He invaded Media and Parthia, and other countries that had revolted from his ancestors, and performed many exploits, from which he was named Antiochus the Great. Elated by his successes, and by the
title which he had derived from them, he invaded Cœle-Syria
and a portion of Cilicia and took them away from Ptolemy Philopator [Epiphanes],1 king of Egypt, who was still a boy. As there was nothing small in his views he marched among the Hellespontines, the Æolians, and the Ionians as though they belonged to him as the ruler of Asia; and, indeed, they had been formerly subjects of the Asiatic
kings. Then he crossed over to Europe, brought Thrace
under his sway, and reduced by force those who would not obey him. He fortified Chersonesus and rebuilt Lysimacheia, which Lysimachus, who ruled Thrace in the time of Alexander, built as a stronghold against the Thracians themselves, but which they destroyed after his death. Antiochus repeopled it, calling back the citizens who had fled, redeeming those who had been sold as slaves, bringing in others, supplying them with cattle, sheep, and agricultural
implements, and omitting nothing that might contribute to its speedy completion as a stronghold; for the place seemed to him to be admirably situated to hold all of Thrace in subjection, and a convenient base of supplies for other operations that he contemplated.
