We see there the custom of evocations of the dead distinctly pointed out, and solemnly practiced in a temple consecrated to these ceremonies; that demonstrates at least the belief and custom of the Greeks. And if Cleonice really appeared to Pausanias and announced his approaching death, can we deny that the evil spirit, or the spirit of Cleonice, is the author of this prediction, unless indeed it were a trick of the priests, which is likely enough, and as the ambiguous reply given to Pausanias seems to insinuate.
Pausanias the historian[305] writes that, 400 years after the battle of Marathon, every night a noise was heard there of the neighing of horses, and cries like those of soldiers exciting themselves to combat. Plutarch speaks also of spectres which were seen, and frightful howlings that were heard in some public baths, where they had put to death several citizens of Chæronea, his native place; they had even been obliged to shut up these baths, which did not prevent those who lived near from continuing to hear great noises, and seeing from time to time spectres.
Dion the philosopher, the disciple of Plato, and general of the Syracusans, being one day seated, towards the evening, very full of thought, in the portico of his house, heard a great noise, then perceived a terrible spectre of a woman of monstrous height, who resembled one of the furies, as they are depicted in tragedies; there was still daylight, and she began to sweep the house. Dion, quite alarmed, sent to beg his friends to come and see him, and stay with him all night; but this woman appeared no more. A short time afterwards, his son threw himself down from the top of the house, and he himself was assassinated by conspirators.
Marcus Brutus, one of the murderers of Julius Cæsar, being in his tent during a night which was not very dark, towards the third hour of the night, beheld a monstrous and terrific figure enter. "Who art thou? a man or a God? and why comest thou here?" The spectre answered, "I am thine evil genius. Thou shalt see me at Philippi!" Brutus replied undauntedly, "I will meet thee there." And on going out, he went and related the circumstance to Cassius, who being of the sect of Epicurus, and a disbeliever in that kind of apparition, told him that it was mere imagination; that there were no genii or other kind of spirits which could appear unto men, and that even did they appear, they would have neither the human form nor the human voice, and could do nothing to harm us. Although Brutus was a little reassured by this reasoning, still it did not remove all his uneasiness.
