A team under the leadership of Professor Anders Winroth is working on new editions of the two recensions of Gratian's Decretum with support of the Andrew W. Mellon Foundation, Yale University, and the Stephan Kuttner Institute of Medieval Canon Law, and with assistance from Yale Digital Collections Center. The digital tools developed for the project will be available at the DESMM Partners site. The new editions aim to replace Emil Friedbergs 1879 edition of the second recension through a fresh collation of the most important manuscripts and a reconsideration of Gratian's sources (both material and formal). The finished edition will be published in the series Monumenta iuris canonici, published by the Kuttner Institute and the Vatican Library. An English translation is also planned.

The purpose of this website is to make the most important working materials of the editorial team available to other scholars already before the edition is published. Users of the site should remember that these are working materials, not the finished edition, and they should use it accordingly.

The first recension of Gratian's Decretum contains approximately 237,800 words, 1,860 chapters ("canons") and 941 dicta (653 dicta post, 252 dicta ante, and 36 dicta initialia).

Edition in Progress

Caveat emptor! These are pages in progress from the new edition of the first recension of Gratian's Decretum, under the general editorship of Anders Winroth. The work on the edition is far from completed and the files are provided as-is, since they contain information that may be useful. Much of the edition corresponds to Friedberg's text with the second-recension additions removed. They will still be much expanded and revised before formal publication. Use your scholarly judgment in employing these files, which should most usefully be considered incomplete accumulations of materials towards an edition.

The files have been produced using Classical Text Editor.

Ivo of Chartres, Works: A collaborative web site with working editions of the works more or less correctly ascribed to Ivo. Gratian used the Panormia and the Tripartita as important sources. The web site contains work by several people, including Martin Brett, Bruce Brasington, Przemysław Nowak, and Christof Rolker
Gregory of St. Grisogono, Polycarpus. Another important source of Gratian, here in the Monumenta Germaniae Historica's working edition, the work of, particularly, Uwe Horst, drawing on collations by Carl Erdmann, and with an introduction by Horst Fuhrmann.

Working materials

Scans of the most up to date editions of Gratian's material sources This link no longer works. Contact Anders Winroth if you want to share one of the scans made for this project.

Many of Emil Friedberg's references to Gratian's material sources (i.e., the original sources of the legal texts that he quoted) are out of date. The project aims to identify the most recent editions of those texts and provides scans of the relevant pages. The edition refers to these sources. No infringement of copyright is intended in providing these brief excerpts.

The material is organized into separate folders for each questio, and each file is numbered: 1.2.3 should be read C. 1 q. 2 c. 3. 22.10 refers to D. 22, c. 10.

No scan has normally been made when the edition is available at the Digital Monumenta Germaniae Historica website or is Paul Hinschius's edition of Pseudo-Isidore, which are already available on the internet (users might also want to compare Karl-Georg Schon's preliminary edition, available at the MGH website).
