Les secrets et merueilles de nature, recueillis de diuers autheurs & diuisez en XVII. liures
A 1586 Lyon compendium of secrets and marvels of nature, compiled from several authors, drawing on Johann Jacob Wecker and Girolamo Ruscelli's edition of Alessio Piemontese's recipes, aimed at readers interested in medicine and pharmacy. Its pictures are small diagrams: a lettered square with crossed diagonals, a pair of arched compartments joined by a bar and key, a winding labyrinth-like channel, and a crossed-bar device, showing how geometric labelling and mechanical schematics were used to explain practical procedures.
