From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
An Excellent way to Prove whether a Person is a Witch or not.
First. Try to obtain St. John's roots and one ounce of herb of the same plant called moto. Write the following letters upon a scrap of paper and put to the root and herbs:
S A T O R + Cross of Jesus Christ mild epos
A R E P O + Cross of Jesus Christ Mesopos
T E N E T + Cross of Jesus Christ Habenepos
O P E R A
R O T A S.
This must be sewed up in a piece of leather, and if you wish to see the witch, only carry the paper with you, but it must be taken in the hour when the first quarter of the moon occurs.
You will then perceive that no witch can remain in the same room with you.
The grimoire Egyptian Secrets of Albertus Magnus lists this spell.
