Catalogue Note
a rare treatise on minerals, metals, gems and gemstones. "That mineralogy had made little advance during the previous hundred years might be inferred from the fact that Giovanni Guidi of Volterra in 1625 dedicated to Ferdinand II, grandduke of Tuscany, and published at Venice a treatise De mineralibus by one of his ancestors who lived from 1464 to 1530, and that there was another printing of this book in 1627. Such an inference, however, would not be quite justified, since Guidi was a jurisconsult and the volume is chiefly concerned with legal questions concerning alchemists, gems, and so forth" (Thorndike VII p. 252). Guidi also includes commentary of his own, and there is much information on the working practices of silver- and goldsmiths, gem merchants, cutters and polishers, etc.
"The section on gems referred to by Thorndike appears on pages 64-73, and as in the other portions of the work, consists of a series of questions raised by Guidi and answered by quotations or statements taken from other authorities, among them Pliny, Isidore of Seville, the Bible, etc. The questions on gems are general and jump from topic to topic with little solid information divulged. Questions on pearls are included. More on gems appears in the section entitled 'De Ornamentis', pp.17-80" (Sinkankas).
