Plutarch, Praecepta gerendae reipublicae
Goodwin, Ed.

Now a statesman ought not only to exhibit himself and his country blameless to the prince, but also to have always for his friend some one of those that are most powerful above, as a firm support of polity; for the Romans are of such a disposition, that they are most ready to assist their friends in their political endeavors. It is good also, when we have received benefit from friendship with princes, to apply it to the advancement of our country; as did Polybius and Panaetius, who through the favor of Scipio to them greatly advantaged their countries for the obtaining felicity. So Caesar Augustus, when he had taken Alexandria, made his entry into it, holding Arius by the hand, and discoursing with him alone of all his familiars; after which he said to the Alexandrians, who expecting the utmost severity supplicated his favor, that he pardoned them first for the greatness of their city, secondly for its builder, Alexander, and thirdly, added he, to gratify this my friend. Is it then fit to compare to this benefit those exceeding gainful commissions and administrations [p. 133] of provinces, in the pursuit of which many even grow old at other men's doors, leaving their own domestic affairs in the mean time unregarded? Or should we rather correct Euripides, singing and saying that, if one must watch and sue at another's court and subject one's self to some great man's familiarity, it is most commendable so to do for the sake of one's country; but otherwise, we should embrace and pursue friendships on equal and just conditions.
