Original fileDe demonstratione, libri quinque
This is a digital scan of a 16th-century title page printed on paper, featuring black typography and a central woodcut printer's device. The device shows a winged horse, Pegasus, leaping over a staff entwined with two snakes and flanked by two overflowing cornucopiae resting on clouds. Handwritten ink annotations in cursive, including the name 'Joannes Dee' at the top and 'Fran' and 'Bernard' flanking the device, appear in the margins, and the paper shows visible yellowing and staining characteristic of an early modern book.
This title page marks the 1560 Parisian edition of Bartolomeo Viotto’s work, bearing the signature of the famous Elizabethan polymath and occultist John Dee, confirming it was part of his personal library.
