Plutarch, Demetrius
Bernadotte Perrin, Ed.

2. To begin, then, Antigonus had two sons by Stratonicé the daughter of Corrhagus, one of whom he named Demetrius, after his brother, arid the other Philip, after his father. This is what the majority of writers say. But some have it that Demetrius was not the son, but the nephew of Antigonus; for his own father died when the boy was quite young, and then his mother immediately married Antigonus, so that Demetrius was considered to be his son. [2] Well then, Philip, who was a few years younger than Demetrius, died. Demetrius, the surviving son, had not the height of his father, though he was a tall man, but he had features of rare and astonishing beauty, so that no painter or sculptor ever achieved a likeness of him. They had at once grace and strength, dignity and beauty, and there was blended with their youthful eagerness a certain heroic look and a kingly majesty that were hard to imitate. [3] And in like manner his disposition also was fitted to inspire in men both fear and favour. For while he was a most agreeable companion, and most dainty of princes in the leisure devoted to drinking and luxurious ways of living, on the other hand he had a most energetic and eager persistency and efficiency in action. Wherefore he used to make Dionysus his pattern, more than any other deity, since this god was most terrible in waging war, and on the other hand most skilful, when war was over, in making peace minister to joy and pleasure.
