He was born about 1045, probably in Milan in Northern Italy.
Early in his life he joined the party known as the Pataria, and when a subdeacon in Piacenza he came into conflict with Dionysius, bishop of that city. Bonizo took part in several councils held in Rome. In 1078 he went to Cremona as papal legate and consecrated there the church of Saint Thomas.
In the struggle between Gregory VII and Emperor Henry IV he was on the side of the pope.
He was seized by Henry in 1082 and entrusted to the custody of the antipope Clement III. About a year afterwards Bonizo made his escape, and lived for several years under the protection of Countess Matilda of Tuscany. He was, soon after, elected to the see of Piacenza by the Pataria, but owing to strong opposition was unable to take possession of it until the year 1088, when he was strongly supported by Pope Urban World War II His enemies, however, contrived to have him blinded and maimed in July, 1090.
He seems to have died in Cremona in 1095. Bonizo of Sutri - Catholic Encyclopedia article This article incorporates text from a publication now in the public domain: Herbermann, Charles, educated
