M. Tullius Cicero Pro P. Sulla 2

[2] And since Lucius Torquatus, O judges, my own most intimate friend, O judges, has thought that if he violated our friendship and intimacy somewhat in his speech for the prosecution, he could by that means detract a little from the authority of my defence, I will unite with my endeavours to ward off danger from my client a defence of my own conduct in the discharge of my duty. Not that I would employ that sort of speech at present, O judges, if my own interest alone were concerned, for on many occasions and in many places I have had, and I often shall have, opportunities of speaking of my own credit. But as he, O judges, has thought that the more he could take away from my authority, the more also he would be diminishing my client's means of protection; I also think, that if I can induce you to approve of the principles of my conduct and my wisdom in this discharge of my duty and in undertaking this defence, I shall also induce you to look favourably on the cause of Publius Sulla.
