M. Tullius Cicero, Orations, The fourteen orations against Marcus Antonius (Philippics)
C. D. Yonge, Ed.

But, while all slavery is miserable, to be slave to a man who is profligate, unchaste, effeminate, never, not even while in fear, sober, is surely intolerable. He, then, who keeps this man out of Gaul, especially by his own private authority, judges, and judges most truly, that he is not consul at all. We must take care, therefore, O conscript fathers, to sanction the private decision of Decimus Brutus by public authority. Nor, indeed, ought you to have thought Marcus Antonius consul at any time since the Lupercalia. For on the day when he, in the sight of the Roman people, harangued the mob, naked, perfumed, and drunk, and labored moreover to put a crown on the head of his colleague, on that day he abdicated not only the consulship, but also his own freedom. At, all events he himself must at once have become a slave, if Caesar had been willing to accept from him that ensign of royalty. Can I then think him a consul, can I think him a Roman citizen, can I think him a freeman, can I even think him a man, who on that shameful and wicked day showed what he was willing to endure while Caesar lived, and what he was anxious to obtain himself after he was dead?
