“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 deathlike slumber will immediately seize upon her, and deprive her of the power of resisting your attempts. Sleep will hold her till break of morning.
