I've recently come across something called the Trithemius Table of Practice, has anyone used this table? I have not read the book that it comes from, The Art of Drawing Spirits into Crystals but various sites that describe the table hint at the fact that it may be able to be used in place of a traditional circle. Is this true? Can the table be used in place of a magic circle or must one have both?
If you have used this Table of Practice, what are your experiences with it? Thank.
