Girolamo Zanchi (1516-1590) was an influential Reformed pastor and professor. Originally from northern Italy, he was converted under the ministry of Peter Martyr Vermigli and subsequently fled north to Protestant Europe. As an instructor and churchman at Strasbourg, Chiavenna, Heidelberg, and Neustadt, Zanchi became a prolific and pioneering Reformed scholastic theologian who sought to wed pious devotion with precise language.
