Antony

This incident strengthened the party of Brutus and Cassius; and when they were taking count of the friends whom they could trust for their enterprise, they raised a question about Antony. The rest were for making him one of them, but Trebonius opposed it. For, he said, while people were going out to meet Caesar on his return from Spain, Antony had travelled with him and shared his tent, and he had sounded him quietly and cautiously; Antony had understood him, he said, but had not responded to his advances; Antony had not, however, reported the conversation to Caesar, but had faithfully kept silence about it.

Upon this, the conspirators again took counsel to kill Antony after they had slain Caesar; but Brutus prevented this, urging that the deed adventured in behalf of law and justice must be pure and free from injustice. But the conspirators were afraid of Antony’s strength, and of the consideration which his office gave him, and therefore appointed some of their number to look out for him, in order that, when Caesar entered the senate-chamber and their deed was about to be done, they might engage Antony outside in conversation about some urgent matter and detain him there.
