On the Secret Works of Art and Nature and the Nullity of Magic

The Bodleian Catalogus catalog, Oxford 1738, Vol. 1, p. 100, cites an edition with the following title: Specula mathematica et perspectiva Mathematical Mirrors and Perspective. Frankfurt, 1614, quarto. In my edition, there is no mention of the treatise de speculis on mirrors on the general or any special title page; however, it is contained within it starting from page 168. As I see from the Bodleian catalog, it begins on that very same page in the edition cited there, so that there is no difference between this and my edition other than in the title, provided it is correctly stated in the aforementioned catalog.

The local university library possesses this very rare piece.

— Epistola de secretis operibus artis et naturae, et de nullitate magiae. Opera Ioannis Dee, Londinensis, e pluribus exemplaribus castigata olim, et ad sensum integrum restituta. Nunc vero a quodam veritatis amatore in gratiam verae scientiae candidatorum foras emissa; cum notis quibusdam partim ipsius Iohannis Dee, partim edentis. Epistle on the secret works of art and nature, and on the nullity of magic. By the work of John Dee of London, formerly corrected from several copies and restored to the complete sense. Now, however, issued forth by a certain lover of truth for the sake of candidates of true science; with certain notes partly by John Dee himself, partly by the editor.
