In a certain monastery of holy Nuns there lived, as a boarder, a young maiden of noble birth, who was tempted by an Incubus that appeared to her by day and by night, and with the most earnest entreaties, the manners of a most passionate lover, incessantly incited her to sin; but she, supported by the grace of God and the frequent use of the sacraments, stoutly resisted the temptation. But, all her devotions, fasts and vows notwithstanding, despite the exorcisms, the blessings, the injunctions showered by exorcists on the Incubus that he should desist from molesting her; in spite of the crowd of relics and other holy objects collected in the maiden’s room, of the lighted candles kept burning there all night, the Incubus none the less persisted in appearing to her as usual, in the shape of a very handsome young man. At last, among other learned men, whose advice had been taken on the subject, was a very erudite Theologian who, observing that the maiden was of a thoroughly phlegmatic temperament, surmised that that Incubus was an aqueous Demon (there are in fact, as is testified by Guaccius, igneous, aerial, phlegmatic, earthly, subterranean demons who avoid the light of day), and prescribed an uninterrupted fumigation in the room. A new vessel, made of glass-like earth, was accordingly brought in, and filled with sweet cane, cubeb seed, roots of both aristolochies, great and small cardamon, ginger, long-pepper, caryophylleæ, cinnamon, cloves, mace, nutmegs, calamite storax, benzoin, aloes-wood and roots, one ounce of triasandalis, and three pounds of half brandy and water; the vessel was then set on hot ashes in order to force up the fumigating vapour, and the cell was kept closed. As soon as the fumigation was done, the Incubus came, but never dared enter the cell; only, if the maiden left it for a walk in the garden or the cloister, he appeared to her, though invisible to others and throwing his arms round her neck, stole or rather snatched kisses from her, to her intense disgust. At last, after a new consultation, the Theologian prescribed that she should carry about her person pills made of the most exquisite perfumes, such as musk, amber, chive, Peruvian balsam, and others. Thus provided, she went for a walk in the garden, where the Incubus suddenly appeared to her with a threatening face, and in a rage. He did not approach her, however, but, after biting his finger as if meditating revenge, disappeared and was never more seen by her.
