“There were two chiefs of this conspiracy, the son of that Brutus whom Sulla put to death, M. Brutus Cæpio, who came for refuge to Cæsar himself after the battle of Pharsalia, and C. Cassius who yielded to him the galleys in the Hellespont, both of Pompey’s party, and with them was joined one of Cæsar’s most intimate friends, Decimus Brutus Albinus. He had always treated them honourably, and with great confidence, and when he was going to the war in Africa, he had given them armies, and the government of the Gauls, to Decimus Brutus of the Transalpine, and to M. Brutus of the Cisalpine. Brutus and Cassius were at this time designed prætors, and were in difference for a jurisdiction which among the citizens is accounted the most honourable of all others, whether they contended out of ambition, or only feigned to do it, lest their conspiracy should be perceived. Cæsar was arbitrator between them, and, as it is said, he acknowledged to his friends that Cassius had reason, but yet he would favour Brutus, so much he loved and honoured him, for all men believed he was his son, because he visited Servilia Cato’s sister at the time she grew with child of Brutus, wherefore it is likewise said, that in the battle of Pharsalia he ordered his captains to have a great care of Brutus’ life.
“However, whether he was ungrateful, or knew nothing of it, or did not believe it, or that he thought his mother’s incontinence of dishonour, whether love of liberty made him prefer his country before his own father, or being of the ancient race of the Bruti who had expelled the kings, and now pricked forward by the reproaches of the people, who on the statues of the old Brutus, and on his prætor’s tribunal had secretly written such words as these, ‘Brutus thou sufferest thyself to be corrupted with gifts. Brutus thou art dead, would to God thou wert now alive; either thy successors degenerate, or thou hast not begot them.’ He, I say, young as he was, chafed by these and such like things, engaged himself in this enterprise as an act worthy his predecessors.
“The discourses concerning the royalty were not then quite extinct, when just as they were going to the senate Cassius took Brutus by the hand, and said, ‘What shall we do if Cæsar’s flatterers propose to make him king?’ To which Brutus answered, that he would not be at the senate. Whereupon, the other again demanded, ‘What if they summon us as prætors, what shall we do then, my friend?’ ‘I will,’ he said, ‘defend my country, even till death.’ Whereupon, Cassius embracing him said, ‘And what persons of quality will you take for companions in so brave an attempt? Do you think there are none but tavern-people and artificers that put writings on your tribunal? Know that they are the prime men of the city, who expect from other prætors only plays and shows; but require their liberty from you as the work of your predecessors.’ Thus they discovered to each other what they had long had in their thoughts; and began to try their own friends, and some of Cæsar’s, according as they knew them capable of good things. They engaged in their design the two brothers, Cæcilius and Bucolianus, Rubrius Rex, Q. Ligarius, M. Spurius, Servilius Galba, Sextius Naso, Pontius Aquila: and of Cæsar’s friends they drew to their conspiracy Decimus, of whom I have already spoken; Caius Casca, Trebonius, Attilius Cimber, Minucius, and Basilus. When they thought they had companions enough, for it was not convenient to communicate this design to all the world, they gave their words one to another without either oath or sacrifice, and yet no one changed his mind or ever discovered the plot.
“There was nothing now wanting but choice of time and place. The time urged, for within four days Cæsar was to depart and take guards. For the place they thought the palace most convenient; for they concluded that all the senators, though they were not made privy to it, yet, seeing the action, would joyfully join with them; which, as it is said, happened at the death of Romulus, after having changed the regal power into tyranny. Wherefore this attempt would have the same success with that; especially being not privily executed, but in the palace, and for the good of the commonwealth. That they needed not to fear anything from Cæsar’s army, being all composed of Roman people; in conclusion, that the authors of this great action doing it publicly, could expect nothing but reward.
