ENOCHIAN
Enochian is a system of magic that was derived from the work of John Dee and Edward Kelley.
The system was passed on to Dee and Kelley by the angels who worked through the pair.
The actual scrying method of Enochian magic was recorded in Dee's diary Libri Mysteriorum.
Enochian magic was subsequently incorporated into the magical practise of the ritual magicians of the Hermetic Order of the Golden Dawn.
