Portaleone, Abraham ben David. De Auro Dialogi Tres [Three Dialogues on the Application of Gold in Medicine]

Medical Treatise by the Italian Jewish Physician, Author of “Shiltei ha-Giborim.” Abraham Portaleone (1542-1612), began his career as a Talmudic scholar, having studied under Rabbis Jacob Fano, and Judah and Abraham Provenzali. Later, he studied medicine at the University of Pavia, qualifying there in 1563 and was subsequently granted a license by the Dukes of Mantua, Guglielmo and Vincenzo I to treat Christians. This distinction, rare for a Jewish physician, was confirmed by Pope Gregory XIV. It was at the command of said Duke Guglielmo that Portaleone wrote this extensive and intriguing study on the use of gold in medicine.
