Moreover, of the men of his own time who were famous for eloquence or learning, there is not one whom he did not make more famous by what he said or wrote in favour of him. For Cratippus the Peripatetic he obtained the Roman citizenship from Caesar, now in power, and he also induced the council of the Areiopagus to pass a decree requesting him to remain at Athens and discourse with the young men, and thus be an ornament to the city.

Furthermore, there are letters from Cicero to Herodes, and others to his son, in which he urges them to study philosophy with Cratippus.These letters are not extant. But Gorgias the rhetorician he censured for leading the young man into pleasures and drinking parties, and banished him from his son’s society.The younger Cicero, in a letter to Tiro ( ad fam. xvi. 21, 6), says that he had found Gorgias useful as a teacher of declamation, but had dismissed him in obedience to his father’s positive command.

This is almost the only one of his Greek letters (there is also a second, addressed to Pelops of Byzantium) which was written in a spirit of anger; and Gorgias he properly rebukes, if, as he was thought to be, he was worthless and intemperate; but towards Pelops he shows a mean and querulous spirit for having neglected to obtain for him certain honorary decrees from the Byzantians.
