effects which the over heating of his furnace foreboded[56]. To the superstitions of Greece and Rome, we are also indebted for those subordinate evil spirits called _genii_, who for many centuries were the subject of numerous spectral illusions. A phantasm of this kind appeared to Brutus in his tent, prophesying that he should be again seen at Philippi. Cornelius Sylla had the first intimation of the sudden febrile attack with which he was seized, from an apparition who addressed him by his name; concluding, therefore, that his death was at hand, he prepared himself for the event, which took place the following evening. The poet Cassius Severus, a short time before he was slain by order of Augustus, saw, during the night, a human form of gigantic size,—his skin black, his beard squalid, and his hair dishevelled. The phantasm was, perhaps, not unlike the evil genius of Lord Byron’s Manfred:— “I see a dusk and awful figure rise Like an infernal god from out the earth; His face wrapt in a mantle, and his form Robed as with angry clouds; he stands between Thyself and me—but I do fear him not.” The emperor Julian was struck with a spectre clad in rags, yet bearing in his hands a horn of plenty, which was covered with a linen cloth. Thus emblematically attired, the spirit walked mournfully past the hangings of the apostate’s tent[57]. We may now advert to the superstitious narratives of the middle ages, which are replete with the notices of similar marvellous apparitions. When Bruno, the Archbishop of Wirtzburg, a short period before his sudden death, was sailing with Henry the Third, he descried a terrific spectre standing upon a rock which overhung the foaming waters, by whom he was hailed in the following words:—“Ho! Bishop, I am thy evil genius. Go whether thou choosest, thou art and shalt be mine. I am not now sent for thee, but soon thou shalt see me again.” To a spirit commissioned on a similar errand, the prophetic voice may be probably referred, which was said to have been heard by John Cameron, the Bishop of Glasgow, immediately before his decease. He was summoned by it, says Spottiswood, “to appear before the tribunal of Christ, there to atone for his violence and oppressions.”
