Rather than lurid, fantastical apocalyptic rantings, these warnings fall too close to the truth. For the general public-both Dee's contemporaries and modern day -his "conversations" with angels and spirits did ruin his reputation. Scholars these days (among many other people) dismiss Dee as a deluded crank or would-be magician -or both. This fascinating man who led a very interesting life during historically interesting times is relagated to a footnote or a few paragraphs by most commentators. I believe that in all of Dr. John Dee's meticulous writings there are valid cases of contact with something or some otherworldly beings. Whether any of them were who they or Kelley said them to be-who knows? The fact that Dee chose to work with the obviously unbalanced Kelley for so long says a lot. In his desire to attain results, Dee probably pushed Kelley even more towards the brink of insanity. Dee's longing desire for these results also led to the "illusions" he was warned about in some sessions. The warnings themselves are very interesting in their own right to me.
In a very great sense, these warnings provide some of the strongest evidence for contact with a higher realm. This could have been from the Oversoul (if there is such a thing), creatures that are on higher planes of existence, beings that share our world but in another dimension -or even the epiphany of angels. In this last case these angelic messengers were sent by Divine Mercy to warn Dee of his hubris and folly. I agree with Cherry Gilchrist that Dee was a great man but not a wise one.
And what of the sinking of the Spanish Armada? Many occultists claim that John Dee raised up spells that caused the storms that sank it. I think he may have had some unique talents-but I don't think he had this kind of power! Dee was out of favor with Queen Elizabeth I by 1588 and apparently wasn't aware of the defeat of the Armada until months afterwards. There is a strange entry in one of his 'spiritual diaries' which has only the most tenuous reference to a threat to England from a foreign fleet in the early 1580s. The rumors that have Dee sinking the Armada with magic seem to date from the 17th century, and they can't be used for anything useful, except that they added to Dee's reputation as a magician! A medallion mentioned by some that say has Dee's magical spells on it to defeat the Spanish Armada (or things of that nature) was actually struck in commemoration of the English victory. Instead of even mentioning Dee, this medallion actually credits God with sinking the Armada.
I may return later to do some more about "the original 007" as I find him a fascinating character. This will be all about Dee for awhile as I am working on other things. Thanks again so much for everyone's thoughtful and intelligent comments! Peace and be well to anyone stopping by!
