He dreamed, namely, that Antigonus himself, with his whole army, was competing in a race over the course and back; he ran vigorously and swiftly at first, then, little by little, his strength failed him; and at last, after he had made the turn, he became weak, breathed heavily, and with difficulty made the finish. And conformably to the vision, Antigonus himself encountered many difficulties by land, and since Demetrius also encountered a great storm and a heavy sea and was cast upon a rough coast which had no harbours, losing many of his ships, he returned without accomplishing anything. Antigonus was at this time almost eighty years old, and his great size and weight, even more than his old age, made it difficult for him to conduct expeditions. He therefore made use of his son instead, whose good fortune and experience now enabled him to conduct the greatest affairs successfully, and whose luxuries, extravagances, and revelries gave his father no concern. For although in time of peace Demetrius plunged deep into these excesses and devoted his leisure to his pleasures without restraint and intemperately, yet in time of war he was as sober as those who were abstemious by nature.
