Plutarch, Cato the Younger
Bernadotte Perrin, Ed.

36. But the Ptolemy in Cyprus, fortunately for Cato, poisoned himself to death. And since the king was said to have left much treasure, Cato determined, while sailing himself to Byzantium, to send his nephew Brutus to Cyprus, since he did not altogether trust Canidius. Then, after reconciling the exiles and citizens of Byzantium and leaving the city in concord, he sailed to Cyprus. [2] Now, there were many furnishings of a princely sort, such as beakers, tables, precious stones, and purple vestments, which had to be sold and turned into money. So Cato, wishing to treat everything with the greatest exactness, and to force everything up to a high price, and to attend to everything himself, and to use the utmost calculation, would not trust even those who were accustomed to the market, but, suspecting all alike, assistants, criers, buyers, and friends, and at last talking privately himself with the purchasers and encouraging each one to bid, he thus succeeded in selling most of the merchandize. [3] For this reason he gave offence to most of his friends, who thought that he distrusted them, and Munatius, the most intimate of them all, he threw into a rage that was well nigh incurable. Hence Caesar also, when he wrote a discourse against Cato,¹ dwelt most bitterly on this part of his denunciation.
