In Adam Boreel (1602-1665): A Collegiant's Attempt to Reform Christianity, Francesco Quatrini offers a reassessment of the life and thought of Adam Boreel, a leading member of the Dutch nonconformist Collegiant movement. Usually regarded as a less important member of this religious group, Boreel is described as a forerunner whose ideas influenced later Collegiants. Drawing on both archival and published sources, Francesco Quatrini provides the first modern biography of Boreel as well as a critical analysis of his writings. He corrects misconceptions about Boreel, who appears here as an intriguing figure who drew his views from several different sources. In this way, Francesco Quatrini revealed that Boreel was a major leader in the era's intellectual discourse.
