Peregrino, Bonaventura (originally SERACH YOM TOB, or SALOMO NAVARRA), a convert from Judaism, was born about 1643 at Casale, not far from the famous Spanish monastery at Montferrat. He was baptized at Bologna Jan. 18, 1665, on which occasion he took the name under which he was afterwards known. According to the spirit of his age, Peregrino endeavored to demonstrate the mysteries of Christianity from the letters of the Old Testament according to the rules of the Cabala (q.v.), and wrote in Italian Pretioso Giqjello sopra ii nome di Dio Tetragrammaton, which, however, has never been published.
