“We will not ask which of the ancient writers mention facts of seemingly-supernatural nature; but rather which of them does not? In Homer, we find Ulysses evoking the spirit of his friend, the soothsayer Tiresias. Preparing for the ceremony of the “festival of blood”, Ulysses draws his sword, and thus frightens away the thousands of phantoms attracted by sacrifice. The friend himself, the so-long-expected Tiresias, dares not approach him so long as Ulysses holds the dreaded weapon in his hand.
Aeneas prepares to descend to the kingdom of the shadows, and as soon as they approach its entrance, the Sibyl who guides him utters her warning to the Trojan hero, and orders him to draw his sword and clear himself a passage through the dense crowd of flitting forms:
“Tuque invade viam, vaginaque eripe ferrum.”
Glanvil gives a wonderful narrative of the apparition of the “Drummer of Tedworth”, which happened in 1661; in which the scin-lecca, or double, of the drummer-sorcerer was evidently very much afraid of the sword.
Psellus, in his work, gives a long story of his sister-in-law being thrown into a most fearful state by an elementary daimon taking possession of her. She was finally cured by a conjurer, a foreigner named Anaphalangis, who began by threatening the invisible occupant of her body with a naked sword, until he finally dislodged him.”
