John Dee and Enochian magic
Type of Spiritual Experience
In order to understand this observation, you need to read the background on John Dee himself
This prophetic ability is only partly attributable to befuddling. Dee suffered a series of crushing events which probably served to render him reasonless and egoless.
On returning to Mortlake after six years Dee found his precious library ruined and many of his prized books and instruments stolen. Dee was married twice and had eight children. In 1578 he married the 23-year-old Jane Fromond (Dee was fifty-one at the time). She was to be the wife that Kelley claimed Uriel had demanded that he and Dee share. Jane died during the plague in Manchester along with a number of his children. So grief may have had a hand in his abilities.
A description of the experience
Enochian Vision Magick – Lon Milo DuQuette
...after nearly five years of working together, years of exhausting magical sessions, and years of traipsing their families around Europe (not to mention a notorious wife-swapping incident), familiarity finally bred contempt, and the two magicians parted company without ever getting into the driver's seat of Enochian magick and turning the key.
Dee's complicated life would draw him back to the English court and the distracting world of political intrigue and survival. In 1588, as the Spanish armada set sail to annihilate England's much smaller fleet (an event Dee predicted years earlier), Elizabeth called again upon her Merlin.
Dee shocked her courtiers by urging the queen to not engage the Spanish armada and keep her ships at bay, prophesying that a mighty storm would scatter and destroy the Spaniards.
Elizabeth wisely heeded Dee's words. The storm manifested right on cue, and in the chaos that followed, the Spanish armada went down to defeat. In many circles Dee was credited with magically raising the tempest that saved England.
The story of this event became instant legend. William Shakespeare, writing only twenty-three years later, would use Dee as the model for Prospero, the storm-raising magician in his play, The Tempest.
