XLVI. When he again hoped to regain the style of royalty, and began to gather around him the form and substance of an empire, he permitted the Thebans to remain independent. The Athenians, however, revolted from him. They erased the name of Diphilus, who was inscribed upon the rolls as "priest of the Saviours,"[320] and decreed that archons should be elected after their ancestral custom; and they also sent to Macedonia to invite Pyrrhus to come and help them, as they perceived that Demetrius was becoming more powerful than they had expected. Demetrius indeed angrily marched upon Athens, and began to besiege the city, but the philosopher Krates, an able and eloquent man, who was sent to make terms with him by the Athenian people, partly by entreaties, and partly by pointing out in what quarter his true interests lay, prevailed upon him to raise the siege. Demetrius now collected what ships he could, and with eleven thousand infantry and a few cavalry soldiers sailed to Asia, intending to detach the provinces of Lydia and Karia from Lysimachus's dominions. At Miletus he was met by Eurydike,[321] the sister of Phila, who brought him her daughter Ptolemäis, who had been long before promised to him in the treaty concluded by the mediation of Seleukus. Demetrius married her, and immediately after the wedding betook himself to gaining over the cities of Ionia, some of which joined him of their own accord, while others were forced to yield to his arms. He also captured Sardis, and several of the officers of Lysimachus deserted to him, bringing him both soldiers and money. When, however, Lysimachus's son Agathokles came to attack him with a large force, he withdrew into Phrygia, meaning if possible to gain possession of Armenia, stir up Media to revolt, and make himself master of the provinces in the interior, among which a fugitive could easily find an abundance of places of refuge. Agathokles pressed him hard, and Demetrius, although victorious in all the skirmishes which took place, was reduced to great straits, as he was cut off from his supplies of provisions and forage, while his soldiers began to suspect him of meaning to lead them to Armenia and Media. Famine now began to distress his army, and he also lost a large body of men, who were swept away in crossing the river Lykus through mistaking the ford. Yet the men did not cease to joke; and one of them wrote before the tent of Demetrius the first verses of the play of OEdipus at Kolonus, slightly altered: "Child of Antigonus, the blind old man, What place is this, at which we have arrived?"
