The Music ceased. Matilda addressed herself to the Spirit: She spoke in a language unintelligible to the Monk, and was answered in the same. She seemed to insist upon something which the Daemon was unwilling to grant. He frequently darted upon Ambrosio angry glances, and at such times the Friar's heart sank within him. Matilda appeared to grow incensed. She spoke in a loud and commanding tone, and her gestures declared that She was threatening him with her vengeance. Her menaces had the desired effect: The Spirit sank upon his knee, and with a submissive air presented to her the branch of Myrtle. No sooner had She received it, than the Music was again heard; A thick cloud spread itself over the Apparition; The blue flames disappeared, and total obscurity reigned through the Cave. The Abbot moved not from his place: His faculties were all bound up in pleasure, anxiety, and surprize. At length the darkness dispersing, He perceived Matilda standing near him in her religious habit, with the Myrtle in her hand. No traces of the incantation, and the Vaults were only illuminated by the faint rays of the sepulchral Lamp.
'I have succeeded,' said Matilda, 'though with more difficulty than I expected. Lucifer, whom I summoned to my assistance, was at first unwilling to obey my commands: To enforce his compliance I was constrained to have recourse to my strongest charms. They have produced the desired effect, but I have engaged never more to invoke his agency in your favour. Beware then, how you employ an opportunity which never will return. My magic arts will now be of no use to you: In future you can only hope for supernatural aid by invoking the Daemons yourself, and accepting the conditions of their service. This you will never do: You want strength of mind to force them to obedience, and unless you pay their established price, they will not be your voluntary Servants. In this one instance they consent to obey you: I offer you the means of enjoying your Mistress, and be careful not to lose the opportunity. Receive this constellated Myrtle: While you bear this in your hand, every door will fly open to you. It will procure you access tomorrow night to Antonia's chamber: Then breathe upon it thrice, pronounce her name, and place it upon her pillow. A death-like slumber will immediately seize upon her, and deprive her of the power of resisting your attempts. Sleep will hold her till break of Morning. In this state you may satisfy your desires without danger of being discovered; since when daylight shall dispel the effects of the enchantment, Antonia will perceive her dishonour, but be ignorant of the Ravisher. Be happy then, my Ambrosio, and let this service convince you that my friendship is disinterested and pure. The night must be near expiring: Let us return to the Abbey, lest our absence should create surprize.'
