Note 23 — Chapter V · THE COLLEGE AND THE “WIZARD WARDEN” OF MANCHESTER.

Dee’s magic crystal, or show stone, was preserved at Strawberry Hill until that famous collection was dispersed. A correspondent in Notes and Queries (2nd S., No. 201) says that John Varley, the painter, well known to have been attached to astrology, used to relate a tradition that the Gunpowder Plot was discovered by Dr. Dee with his magic mirror; and he urged the difficulty, if not the impossibility, of interpreting Lord Mounteagle’s letter without some other clue or information than hitherto gained. In a Common Prayer Book, printed by Baskett in 1737, is an engraving of the following scene: In the centre is a circular mirror on a stand, in which is the reflection of the Houses of Parliament by night, and a person entering carrying a dark lantern. Next, on the left side are two men in the costume of James’s time, looking into the mirror—one evidently the King, the other evidently, from his secular habit, not the doctor (Dee), but probably Sir Kenelm Digby. On the right side, at the top, is the eye of Providence darting a ray on the mirror; and below are some legs and hoofs, as if evil spirits were flying out of the picture. The plate is inserted before the service for the 5th November, and would seem to represent the method by which, under Providence (as is evidenced by the eye), the discovery of the Gunpowder Plot was at that time seriously believed to have been effected. The tradition must have been generally and seriously believed, or it never could have found its way into a Prayer Book printed by the King’s printer.
