Secreti bellissimi del cavaliere G.M. Bonardi [sic] Frateggiano, doue si contengono varii effetti dalla natura prodotti
A 1603 Italian book of secrets, printed in Ferrara by V. Baldini and attributed to Gio. Maria Bonardo Fratteggiano, a writer active 1563-1589, offering recipes and natural effects for a general curious readership. The pictures are small woodcuts: an ornate historiated initial with a dragon-like figure in a decorative border, and a bearded astrologer seated on a plinth holding a celestial globe, a sun and crescent, and compasses amid scattered stars, a clear model for emblematic or astrological ornament.
