Bonizo, a native of Cremona, was bishop of Sutri (in the Patrimonium Petri to the north of Rome) between 1075–1076. He was forced to abandon his see by sympathizers of the emperor and he sought refuge with Matilda of Tuscany. He was present at the funeral of Anselm of Lucca at Mantua in 1086 and compiled a canon law collection in the late 1080’s or early 1090’s after having been bishop of Piacenza, where he was mutilated and again driven out by his opponents. Little else is known of his life.

Content, Sources, and Structure

In the epilogue Bonizo calls his work a brevis ac compendiosa dictatiuncula ex sanctorum patrum autenticis canonibus (canon 10. 79). The title Liber de vita christiana is used in the Ms Florence. The collection is systematically organized and divided into ten books; blocks of texts taken from other collections are left intact. There are no book titles or capitulationes, but each canon has a rubric in textu. Bonizo inserted texts of his own among the canons of the collection, making the Liber de vita christiana part canon law collection and part treatise.

Bonizo made extensive use of the Liber decretorum of Burchard and the collection of Anselm. He was more interested in ecclesiastical discipline than Anselm, however, and paid more attention to marriage. Striking is the extent to which he used older material: monastic rules, the Hibernensis, capitularies, Ansegis and Benedictus Levita and the Collectio Bonaevallensis. Canon 10. 46 may have been taken from the 10th century Beneventan Collectio IX librorum in the Ms Vat. lat. 1349. Bonizo used older collections particularly for penitential texts. He also used penitentials themselves. For Roman law Bonizo used the Codex and Epitome Iuliani. [175]

He made use of a series of forged texts attributed to popes Symmachus and Celestine (canons 10. 44–47) which is also appended to the collection of Saint-Hilaire in a manuscript now at Reims: Omnes enim quos, Sive quis autem sacerdos cum filia spirituali and Non debet episcopus, presbiter aut diaconus commisceri. This series also appears in the early core of the Collectio Ambrosiana I which had not yet been augmented with canons from the Tripartita. It is also found in the appendix to the Sinemuriensis in the Ms Orléans, BM 306 (canons 604–608), which made use of Italian sources.

The collection of Bonizo was used in turn for the collection Polycarpus. Bonizo’s version of the arbor consanguinitatis, which was based on that of Burchard, was adopted by a number of canonists who made no other use of the collection. The papal chronicle in the 4th book of the Liber de vita christiana was also widely received.
