Peter Martyr Vermigli (8 September 1499 – 12 November 1562) was a Reformed theologian of the Reformation period. Born in Florence, he fled Italy to avoid the Roman Inquisition in 1542. He lectured on the Bible in Strasbourg, Zürich and at the University of Oxford. Vermigli was primarily a professor of the Bible, especially the Old Testament. His lectures on I Corinthians, Romans, Judges, Kings, Genesis, and Lamentations were turned into commentaries.
Beginning in 1549, Vermigli became involved in controversy regarding the Eucharist. He published his disputation with Catholics at Oxford University along with a tract on the subject. He later wrote treatises on the Eucharist against Catholics as well as Lutherans. After Vermigli's death, Robert Masson collected the doctrinal passages scattered throughout these commentaries into a systematic theology called the Loci Communes, which became Vermigli's most well-known work. Several of Vermigli's letters and shorter treatises were also published during and after his life. Beginning in 1994, scholars began translating his works into modern English in a series called the Peter Martyr Library.
