John Dee - Tuba Veneris (Latin, 1580)
This little grimoire written by John Dee predates his magical workings documented in the Mysteriorum Libri. It may be an example of the Ars Steganographiae of Abbott Trithemius. For a critical edition with German translation, commentary and critical apparatus, see Jorg M. Meier, Das Buchlein der Venus (Bonn 1990). NOTE: This transcription is based on several manuscripts. Primary ones are: W = London, the Warburg Institute.
