Marcus Tullius Cicero,
For Quintus Roscius the Actor…
“ Will he throw discredit on that man as a witness whom he approved of as a judge? Will he say that you ought not to trust that man whom he has trusted himself? Will he disparage the credit of that man as a witness to the judge, when on account of his opinion of his good faith and scrupulousness as a judge, he brought witnesses before him? When I produce that man as a witness, will he dare to find fault with him, when if I were to bring him as a judge even, he would be bound not to decline him? Oh, but says he, he was not on his oath when he said that to Luscius and Manilius. ”
