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.
