Demetrius

But almost all the other lines afford many examples of men who killed their sons, and of many who killed their mothers and wives; and as for men killing their brothers, just as geometricians assume their postulates, so this crime came to be a common and recognized postulate in the plans of princes to secure their own safety.

In proof that in the beginning Demetrius was naturally humane and fond of his companions, the following illustration may be given. Mithridates the son of Ariobarzanes was a companion of his, and an intimate of the same age. He was one of the courtiers of Antigonus, and though he neither was nor was held to be a base fellow, still, in consequence of a dream, Antigonus conceived a suspicion of him.

Antigonus dreamed, namely, that he was traversing a large and fair field and sowing gold-dust. From this, to begin with, there sprang up a golden crop, but when he came back after a little while, he could see nothing but stubble. In his vexation and distress, he heard in his dream sundry voices saying that Mithridates had reaped the golden crop for himself and gone off to the Euxine Sea.
