Now Brutus, feeling that the noblest spirits of Rome for virtue birth, or courage were depending upon him, and surveying with himself all the circumstances of the dangers they were to encounter, strove indeed, as much as possible, when abroad, to keep his uneasiness of mind to himself, and to compose his thoughts; but at home, and especially at night, he was not the same man, but sometimes against his will his working care would make him start out of his sleep, and other times he was taken up with further reflection and consideration of his difficulties, so that his wife that lay with him could not choose but take notice that he was full of unusual trouble, and had in agitation some dangerous and perplexing question. Porcia, as was said before, was the daughter of Cato, and Brutus, her cousin-german, had married her very young, though not a maid, but after the death of her former husband, by whom she had one son that was named Bibulus; and there is a little book, called Memoirs of Brutus, written by him, yet extant. This Porcia, being addicted to philosophy, a great lover of her husband, and full of an understanding courage, resolved not to inquire into Brutus's secrets before she had made this trial of herself. She turned all her attendants out of her chamber, and taking a little knife, such as they use to cut nails with, she gave herself a deep gash in the thigh; upon which followed a great flow of blood, and soon after, violent pains and a shivering fever, occasioned by the wound. Now when Brutus was extremely anxious and afflicted for her, she, in the height of all her pain, spoke thus to him: "I, Brutus, being the daughter of Cato, was given to you in marriage, not like a concubine, to partake only in the common intercourse of bed and board, but to bear a part in all your good and all your evil fortunes; and for your part, as regards your care for me, I find no reason to complain; but from me, what evidence of my love, what satisfaction can you receive, if I may not share with you in bearing your hidden griefs, nor to be admitted to any of your counsels that require secrecy and trust? I know very well that women seem to be of too weak a nature to be trusted with secrets; but certainly, Brutus, a virtuous birth and education, and the company of the good and honourable, are of some force to the forming our manners; and I can boast that I am the daughter of Cato, and the wife of Brutus, in which two titles though before I put less confidence, yet now I have tried myself, and find that I can bid defiance to pain." Which words having spoken, she showed him her wound, and related to him the trial that she had made of her constancy; at which he being astonished, lifted up his hands to heaven, and begged the assistance of the gods in his enterprise, that he might show himself a husband worthy of such a wife as Porcia. So then he comforted his wife.
But a meeting of the senate being appointed, at which it was believed that Caesar would be present, they agreed to make use of that opportunity; for then they might appear all together without suspicion; and, besides, they hoped that all the noblest and leading men of the commonwealth, being then assembled as soon as the great deed was done, would immediately stand forward and assert the common liberty. The very place too where the senate was to meet seemed to be by divine appointment favourable to their purpose. It was a portico, one of those joining the theatre, with a large recess, in which there stood a statue of Pompey, erected to him by the commonwealth, when he adorned that part of the city with the porticos and the theatre. To this place it was that the senate was summoned for the middle of March (the Ides of March is the Roman name for the day); as if some more than human power were leading the man thither, there to meet his punishment for the death of Pompey.
As soon as it was day, Brutus, taking with him a dagger, which none but his wife knew of, went out. The rest met together at Cassius's house, and brought forth his son that was that day to put on the manly gown, as it is called, into the forum; and from thence, going all to Pompey's porch, stayed there, expecting Caesar to come without delay to the senate. Here it was chiefly that any one who had known what they had purposed, would have admired the unconcerned temper and the steady resolution of these men in their most dangerous undertaking; for many of them, being praetors, and called upon by their office to judge and determine causes, did not only hear calmly all that made application to them and pleaded against each other before them, as if they were free from all other thoughts, but decided causes with as much accuracy and judgment as they had heard them with attention and patience. And when one person refused to stand to the award of Brutus, and with great clamour and many attestations appealed to Caesar, Brutus, looking round about him upon those that were present, said, "Caesar does not hinder me, nor will he hinder me, from doing according to the laws."Yet there were many unusual accidents that disturbed them and by mere chance were thrown in their way. The first and chiefest was the long stay of Caesar, though the day was spent, and he being detained at home by his wife, and forbidden by the soothsayers to go forth, upon some defect that appeared in his sacrifice. Another was this:
