Peter Martyr Vermigli (1499–1562) was an Italian-born Reformed theologian and one of the most influential figures of the sixteenth-century Reformation. Born in Florence and trained as an Augustinian canon, he embraced Protestant convictions and left Italy in 1542, going on to teach at Strasbourg, at Oxford as Regius Professor of Divinity under Edward VI, and finally at Zurich. A formidable biblical exegete and systematic thinker, his posthumously compiled Loci Communes (Common Places) became a standard of Reformed theology, and his writings shaped Reformed thought across Europe and England.
