In his final days, the herds of horses, as he found out, which he had dedicated to the river Rubicon when he crossed it, and had let loose without a keeper, stubbornly refused to graze and wept copiously. Again, when he was offering sacrifice, the soothsayer Spurinna warned him to beware of danger, which would come not later than the Ides of March; and on the day before the Ides of that month a little bird, the king-wren, with a sprig of laurel, flew into the Hall of Pompey pursued by others of various kinds from the nearest grove, which tore it to pieces in the same place.
In fact the very night when the day of his murder began to dawn he dreamt now that he was flying above the clouds, and now that he was clasping the hand of Jupiter; and his wife Calpurnia thought that the pediment of their house fell, and that her husband was stabbed in her arms; and suddenly the door of the room flew open of its own accord.
Both for these reasons and because of poor health having hesitated for a long time whether to stay at home and put off what he had planned to do in the senate; but at last, as Decimus Brutus was urging him on not to disappoint the full meeting which had for some time been waiting for him, he went forth almost at the fifth hour; and when a note revealing the plot was handed to him by someone on the way, he put it with others which he held in his left hand, intending to read them presently. Then, after several victims had been slain, and he could not get favourable omens, he entered the House in defiance of portents, laughing at Spurinna and calling him a false prophet, because the Ides of March were come without bringing him harm; though Spurinna replied that they had indeed come, but they had not gone.
