Plutarch Demetrius 46

[1] But as soon as he had entered upon the path of hope, as upon a royal highway, and had gathered about himself a body and form of sovereignty, he restored to the Thebans their ancient form of government; the Athenians, however, revolted from him. They voted to elect archons, as had been their custom of old, and took away from Diphilus, who had been appointed priest of the Saviour-gods, the privilege of giving his name to the current year; ¹ and when they saw that Demetrius had more strength than they expected, they summoned Pyrrhus to their aid from Macedonia. Demetrius came up against them in a rage, and began a strenuous siege of the city.

[2] But the people sent to him Crates the philosopher, a man of great repute and influence, and Demetrius, partly because he was induced to grant the ambassador’s appeals in behalf of the Athenians, and partly because he was convinced when the philosopher showed him what would be an advantageous course, raised the siege, and after assembling all the ships he had, ² and putting on board eleven thousand soldiers, together with his cavalry, he sailed for Asia, to wrest Caria and Lydia from Lysimachus.

[5] Agathocles followed him, and though Demetrius had the advantage in their engagements, he was shut off from getting provisions and forage, and was in great straits; besides, his soldiers were suspicious that he was trying to make his way towards Armenia and Media. And not only did famine press them harder, but also some mistake was made in crossing the river Lycus, and a large number of men were carried away by the current and lost. But nevertheless they would have their pleasantries; and one of them wrote up in front of the tent of Demetrius the opening words of the Oedipus, slightly changed:—
