In offering certain sacrifices, he was to wear, according to the usage prescribed on such occasions, a garland of flowers, and it happened that the officer who brought the garland, by mistake or accident, presented it wrong side before. Again, in some procession which was formed, and in which a certain image of gold, made in honor of him, was borne, the bearer of it stumbled and fell, and the image was thrown upon the ground. This was a very dark presage of impending calamity. Then a great number of vultures and other birds of prey were seen, for a number of days before the battle, hovering over the Roman army; and several swarms of bees were found within the precincts of the camp. So alarming was this last indication, that the officers altered the line of the intrenchments so as to shut out the ill-omened spot from the camp. These and other such things had great influence upon the mind of Cassius, in convincing him that some great disaster was impending over him. Nor was Brutus himself without warnings of this character, though they seem to have had less power to produce any serious impression upon his mind than in the case of Cassius. The most extraordinary warning which Brutus received, according to the story of his ancient historians, was by a supernatural apparition which he saw, some time before, while he was in Asia Minor. He was encamped near the city of Sardis at that time. He was always accustomed to sleep very little, and would often, it was said, when all his officers had retired, and the camp was still, sit alone in his tent, sometimes reading, and sometimes revolving the anxious cares which were always pressing upon his mind. One night he was thus alone in his tent, with a small lamp burning before him, sitting lost in thought, when he suddenly heard a movement as of some one entering the tent. He looked up, and saw a strange, unearthly, and monstrous shape, which appeared to have just entered the door and was coming toward him. The spirit gazed upon him as it advanced, but it did not speak. Brutus, who was not much accustomed to fear, boldly demanded of the apparition who and what it was, and what had brought it there. "I am your evil spirit," said the apparition. "I shall meet you at Philippi." "Then, it seems," said Brutus, "that, at any rate, I shall see you again." The spirit made no reply to this, but immediately vanished. Brutus arose, went to the door of his tent, summoned the sentinels, and awakened the soldiers that were sleeping near. The sentinels had seen nothing; and, after the most diligent search, no trace of the mysterious visitor could be found.
