This coming Wednesday, at the recommendation of Frater Ex Nihilo – John Dee’s Five Books of Mystery, as edited by Joseph H. Peterson.
They request that you read the following pages:
42-46: Just pretty pictures of some of the tools of the art, what was known, and what was constructed.
56 – 86: Dee’s long prayer, receiving of most of the instructions for the magical instruments, getting a bit bitch slapped by the angels multiple times.
245-254: Lots of stuff, but this is where the shewstone materializes from the spirit realm.
If you have trouble with the first link, try this one. You can scroll down and manually load the PDF.
