From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
How to Manage in Selling Cattle you wish to Dispose of.

Every one shall run after me to purchase my cattle from me. As true as Christ baptized with the water from the river Jordan, so I, too, baptize thee. + + +
The grimoire Egyptian Secrets of Albertus Magnus lists this spell.
