There are endless accounts of spirits appearing to men on earth. Here are a few of them:--Marcus Brutus, one of the murderers of Julius Cæsar, being one night in his tent, saw a monstrous figure coming in about the third hour of night. Brutus immediately cried out, "What art thou, a man or a god? and why art thou come hither?" The spectre answered, "I am thy evil genius; thou shalt see me at Philippi." Brutus, with feigned calmness, answered, "I will meet thee there." Disordered, however, in body, and disturbed in mind, Brutus related the affair to Cassius, who, being of the sect of Epicurus, told Brutus that what he supposed he saw was nothing more than mere fancy; that there were no such things as genii or other spirits which could appear to man; that even if they should appear, they could not assume a human shape or voice, and had no power over men. Though Brutus was somewhat encouraged by what Cassius said, he could not entirely overcome his uneasiness. In the midst of the battle of Philippi, Brutus thought he saw Julius Cæsar, whom he had assassinated, riding to him at full speed, which so terrified him that he fell upon his own sword. Cassius also fell there under the hand of his freedman Pindarus. Pausanius writes that, four hundred years after the battle of Marathon, there were heard, in the place where it was fought, the neighing of horses, and the shouts of soldiers animating one another to the fight. Plutarch also speaks of spectres seen and dreadful howlings heard in the public baths, where several citizens of Chœronea, his native town, had been murdered. He says that the inhabitants had been obliged to shut up these baths, but that, notwithstanding this precaution, great noises continued to be heard, and dreadful spectres were frequently seen by the neighbours. Plutarch frequently makes mention of spectres and apparitions; particularly he says, that, in the famous battle above alluded to, several soldiers saw the apparition of Theseus fighting for the Greeks and against the Persians. It is recorded in Socrates, that after the defeat of the Athenian army under the prætor Laches, as he was flying in company with the Athenian general, and came to a place where several roads met, he refused to go the same road that the others took, and the reason being asked him, he answered that his genius, or familiar spirit, who frequently attended him, dissuaded him from it; and the event justified the precaution, for all those who went a different way from him were killed or made prisoners by the enemy's cavalry. When Bruno, Archbishop of Wirtzburgh, a short time before his sudden death, was sailing with Henry III., he descried a terrific spectre standing upon a rock which overhung the foaming waters, by whom he was thus hailed; "Ho! bishop, I am thy evil genius. Go whither thou choosest, thou art and shalt be mine. I am not now sent for thee, but soon thou shalt see me again."
