Ivo of Chartres

Ivo von Chartres , French Yves de Chartres (* around 1040 probably in Chartres ; † December 23, 1115 or 1116 in Chartres) was a French church reformer and bishop of Chartres. He is venerated as a saint.


Ivo may have studied in Bec Abbey , where he is believed to have been a student of Lanfranc and fellow student of Anselm , who later became Archbishops of Canterbury .

He was the first abbot to head the Canons' Monastery of St. Quentin in Beauvais, founded in 1067 . Finally, he was elected Bishop of Chartres in 1090 , invested by King Philip I of France and consecrated in Rome by Pope Urban II . When he refused to divorce the French king, who wanted to marry Bertrade of Anjou , he was persecuted and captured in 1092. King Philip was excommunicated several times between 1095 and 1104.

In the investiture dispute Ivo took a moderate position, but he did not live to see the solution of the dispute based on his ideas through the Worms Concordat 1122.

Ivo is considered to be an important pioneer of the classic development of high medieval scholasticism and canon law .

The time of his canonization is unknown, his feast day is December 23rd .


Ivo von Chartres has traditionally been assigned four collections of canonical content.

Collectio Tripartita A

The tripartita consists of three parts. The first two parts are collectively referred to as A ; they were compiled around the year 1094 and are therefore much older than the third part of the collection called B (see below). Part A is largely arranged in chronological order and contains genuine and false papal letters and council resolutions (mainly from Pseudoisidor ), excerpts from father texts as well as Roman and Franconian law . Ivo's authorship is not assured.


The decretum was written around 1094. It is divided into 17 books with 3760 chapters and covers almost the entire area of ​​canon law. The canons are taken from decretals , councils , church fathers , Roman law and other normative texts. The decretum depends on the decree of Burchard von Worms , the Tripartita A and numerous smaller collections. Ivo added many patristic texts to his collection that cannot be found in any previous canon law collection. The books on the sacraments are particularly carefully prepared.


The third collection, called Panormia , was created after the Decretum (but before about 1120) and has often been ascribed to Ivo since the 12th century; but his authorship is not proven. The work consists of eight books with 1038 chapters and is essentially an abridged version of the Decretum . It was comparatively short and its internal order allowed the location to be found quickly. Presumably for this reason the collection was widely distributed by hand. The work first appeared in print in Basel in 1499 .

Collectio Tripartita B

Like the Panormia , the collection called Tripartita B is essentially an abridged version of the Decretum . The collection was created after 1095 and combined with Tripartia A to form one work. No manuscript that is physically complete today contains only Tripartita A or only Tripartita B, although both were created separately and must have existed separately for a while. In addition, Ivo's authorship is not guaranteed.


Already in St. Quentin and especially as Bishop of Chartres Ivo wrote numerous letters, 288 of which have survived. Individual letters and collections of the same were already in circulation during his lifetime in France, but also in England, Germany and Italy. Probably shortly after his death, two large collections were created, which contain almost all of the letters known today and which were copied very frequently in the course of the 12th century. Around 150 medieval copies have survived to this day; This makes Ivo's collection of letters one of the most widespread of the entire Middle Ages. The letters received deal with very different subjects. a. Ivo's judgments and opinions on the marriages of various nobles, on understanding the Eucharist and repeatedly on various controversial bishops.
