Arbatel of Magick 
The spiritual Wisdom of the Ancients

In the Name of the Creator of all things both visible and invisible, who revealeth his Mysteries out of his Treasures to them that call upon him; and fatherly and mercifully bestoweth those his Secrets upon us without measure. May he grant unto us, through his onely-begotten Son Jesus Christ our Lord, his ministring spirits, the revealers of his secrets, that we may write this Book of Arbatel, concerning the greatest Secrets which are lawful for man to know, and to use them without offence unto God. Amen.
