In the course of my rituals, I've created several talismen and lamens for use with the Art of Drawing Spirits into Crystals. Below you will find the Lamen of Kammael, and an image of my "Table of Practice" I use with the rit. I just put the crystal in the center and read the evocations while wearing the lamen.
As you can see, I wrote the names of God around the outer edges in the "Celestial Script" from Agrippa, but the text of the "grimoire" lists them in the Latin script. I just liked how it looked.
