There came a man up to Casca, one of the company, and, taking him by the hand, "You concealed," said he, "the secret from us, but Brutus has told me all." At which words when Casca was surprised, the other said laughing, "How came you to be so rich of a sudden, that you should stand to be chosen aedile?" So near was Casca to let out the secret, upon the mere ambiguity of the other's expression. Then Popilius Laenas, a senator, having saluted Brutus and Cassius more earnestly than usual, whispered them softly in the ear, and said, "My wishes are with you, that you may accomplish what you design, and I advise you to make no delay, for the thing is now no secret."This said, he departed, and left them in great suspicion that the design had taken wind. In the meanwhile, there came one in haste from Brutus's house and brought him news that his wife was dying.
For Porcia, being extremely disturbed with expectation of the event, and not able to bear the greatness of her anxiety, could scarce keep herself within doors; and at every little noise or voice she heard, starting up suddenly, like those possessed with the bacchic frenzy, she asked every one that came in from the forum what Brutus was doing, and sent one messenger after another to inquire. At last, after long expectation and waiting, the strength of her constitution could hold out no longer; her mind was overcome with her doubts and fears, and she lost the control of herself, and began to faint away. She had not time to betake herself to her chamber, but, sitting as she was amongst her women, a sudden swoon and a great stupor seized her, and her colour changed, and her speech was quite lost. At this sight her women made a loud cry, and many of the neighbours running to Brutus's door to know what was the matter, the report was soon spread abroad that Porcia was dead; though with her women's help she recovered in a little while, and came to herself again. When Brutus received this news, he was extremely troubled, not without reason, yet was not so carried away by his private grief as to quit his public purpose.
For now news was brought that Caesar was coming, carried in a litter. For, being discouraged by the ill-omens that attended his sacrifice, he had determined to undertake no affairs of any great importance that day, but to defer them till another time, excusing himself that he was sick. As soon as he came out of his litter, Popilius Laenas, he who but a little before had wished Brutus good success in his undertaking, coming up to him, conversed a great while with him, Caesar standing still all the while, and seeming to be very attentive. The conspirators (to give them this name), not being able to hear what he said, but guessing by what themselves were conscious of that this conference was the discovery of their treason, were again disheartened, and, looking upon one another, agreed from each other's countenances that they should not stay to be taken, but should all kill themselves. And now when Cassius and some others were laying hands upon their daggers under their robes, and were drawing them out, Brutus, viewing narrowly the looks and gesture of Laenas, and finding that he was earnestly petitioning and not accusing, said nothing, because there were many strangers to the conspiracy mingled amongst them: but by a cheerful countenance encouraged Cassius. And after a little while, Laenas, having kissed Caesar's hand, went away, showing plainly that all his discourse was about some particular business relating to himself.
Now when the senate was gone in before to the chamber where they were to sit, the rest of the company placed themselves close about Caesar's chair, as if they had some suit to make to him, and Cassius, turning his face to Pompey's statue, is said to have invoked it, as if it had been sensible of his prayers. Trebonius, in the meanwhile, engaged Antony's attention at the door, and kept him in talk outside. When Caesar entered, the whole senate rose up to him. As soon as he was sat down, the men all crowded round about him, and set Tillius Cimber, one of their own number, to intercede in behalf of his brother that was banished; they all joined their prayers with his, and took Caesar by the hand, and kissed his head and his breast. But he putting aside at first their supplications, and afterwards, when he saw they would not desist, violently rising up, Tillius with both hands caught hold of his robe and pulled it off from his shoulders, and Casca, that stood behind him, drawing his dagger, gave him the first, but a slight wound, about the shoulder. Caesar snatching hold of the handle of the dagger, and crying out aloud in Latin, "Villain Casca, what do you?" he, calling in Greek to his brother, bade him come and help. And by this time, finding himself struck by a great many hands, and looking around about him to see if he could force his way out, when he saw Brutus with his dagger drawn against him, he let go Casca's hand, that he had hold of and covering his head with his robe, gave up his body to their blows. And they so eagerly pressed towards the body, and so many daggers were hacking together, that they cut one another; Brutus, particularly, received a wound in his hand, and all of them were besmeared with the blood.
