M. Tullius Cicero Pro S. Roscio Amerino 120

[120] Moreover, the thing demanded of you was such that it made no difference whether you refused it or confessed yourself guilty of the crime. And as this is the case, I ask of you why you refused it? When Sextus Roscius was murdered they were there. The slaves themselves, as far as I am concerned, I neither accuse nor acquit; but the point which I see you contending for, namely, that they be not submitted to the question, is full of suspicion. But the reason of their being held in such horror by you, must be that they know something, which, if they were to tell, will be pernicious to you. Oh, say you, it is unjust to put questions to slaves against their masters. Is any such question meant to be put? For Sextus Roscius is the defendant, and when inquiry is being made into his conduct, you do not say that you are their masters. Oh, they are with Chrysogonus. I suppose so; Chrysogonus is so taken with their learning and accomplishments, that be wishes these men—men little better than labourers from the training of a rustic master of a family at Ameria, to mingle with his elegant youths, masters of every art and every refinement—youths picked out of many of the politest households.
