While this was going on, Antiochus happened to be at Seleucia, on the Zeugma, when the Navarchus Diognetus arrived from Cappadocia, on the Euxine, bringing Laodice, the daughter of king Mithridates, an unmarried girl, destined to be the king’s wife. This Mithridates boasted of being a descendant of one of the seven Persians who killed the Magus, and he had maintained the sovereignty handed down from his ancestors, as it had been originally given to them by Darius along the shore of the Euxine. Having gone to meet the princess with all due pomp and splendour, Antiochus immediately celebrated his nuptials with royal magnificence. The marriage having been completed, he went to Antioch, and after proclaiming Laodice queen, devoted himself thenceforth to making preparation for the war. Meanwhile Molon had prepared the people of his own Satrapy to go all lengths, partly by holding out to them hopes of advantages to be gained, and partly by working on the fears of their chief men, by means of forged letters purporting to be from the king, and couched in threatening terms. He had also a ready coadjutor in his brother Alexander; and had secured the co-operation of the neighbouring Satrapies, by winning the goodwill of their leading men with bribes. It was, therefore, at the head of a large force that he took the field against the royal generals. Terrified at his approach Xenon and Theodotus retired into the cities; and Molon, having secured the territory of Apollonia, had now a superabundance of supplies.
