Grimoirium Verum

In the first part is contained various dispositions of characters, by which powers the spirits or, rather, the devils are invoked, to make them come when you will, each according to his power, and to bring whatever is asked: and that without any discomfort, providing also that they are content on their part; for this sort of creature does not give anything for nothing. In the first part is taught the means of calling forth the Elemental Spirits of the Air, Earth, Sea or of the Infernus, according to their affinities. In the second part are expressed the secrets, both Natural and Supernatural which operate by the power of the Dmons. You will find the manner to make use of them, and all without deceit.
