Magiae naturalis
Porta's Natural magic was originally published in four "books" (=chapters) and later expanded to 20 chapters. The text is devoted to various experiments, distillation, transmutation of metals, artificial gems, etc. The 17th chapter on optics is the most important: it went through 18 editions in different languages prior 1600.
