The murmurs and the discontent of the people at the indications that the time for the realization of their fears was drawing nigh, became more and more audible, and at length a conspiracy was formed to put an end to the danger by destroying the ambitious aspirant's life.

Two stern and determined men, Brutus and Cassius, were the leaders of this conspiracy.

They matured their plans, organized their band of associates, provided themselves secretly with arms, and when the Senate convened, on the day in which the decisive vote was to have been passed, Caesar himself presiding, they came up boldly around him in his presidential chair, and murdered him with their daggers.
Antony, from whom the plans of the conspirators had been kept profoundly secret, stood by, looking on stupefied and confounded while the deed was done, but utterly unable to render his friend any protection.
Cleopatra immediately fled from the city and returned to Egypt.
Arsinoe had gone away before.

Caesar, either taking pity on her misfortunes, or impelled, perhaps, by the force of public sentiment, which seemed inclined to take part with her against him, set her at liberty immediately after the ceremonies of his triumph were over.

He would not, however, allow her to return into Egypt, for fear, probably, that she might in some way or other be the means of disturbing the government of Cleopatra.
