13th-century canon law manuscript containing an incomplete text of the 'Decretum' of Gratian with the gloss of Bartholomeus Brixiensis, a correction of the gloss of Johannes Teutonicus Zemeke.

The work has been dated to the 13th century by Borland, and to the 14th century by Dolezalek. The manuscript was probably written in Italy and illuminated in France or England. The main body of text is written in double columns of 50 lines, with glosses in two columns.

Both the 'Decretum' and the gloss are written in littera textualis, with later marginal and interlineal additions and glosses written by a professional scribe. Dolezalek has identified these additions as bearing the following sigla: 'la.gi.', 'la', 'gi.', 'hu.', 'gi.hu.', 'jo.fi.', 'jo.fa.', 'jo.d.', archi.', 'guydo'. Dolezalek suggests that these relate to additions referencing the works of Guido de Baysio, Johannes de Friburgo, Johannes de Deo, and others.

The division of the 'Decretum' is as follows:

Gratian, 'Concordia discordantium canonum ac primum de jure naturae et constitutionis', in 101 distinctions. Folios 1r-93v.

Gratian, 'Causae', containing 36 causes. Folios 93v-356r. Inserted with Causa 33 at folios 314r-344v is 'de penetentiate'.

Gratian, 'De consacratione'. Incomplete, stops halfway through Division 5, Chapter 38, lacking the final 2 Chapters. Folios 356r-385v.

The manuscript is decorated throughout, and the 'concordia discordantium' and each 'causa' is introduced by an illuminated miniature and a large decorated initial. The miniature and initial of the 'concordia' on the recto side of folio 1 differ slightly from the decoration found in the rest of the volume.

The miniature on the recto side of folio 1 consists of triple trefoiled arches with backgrounds of crimson and blue diaper. In the centre arch there is a crowned figure who is seated and holding a sceptre which is surmounted by a fleur de lys. He is wearing a blue cloak lined with red and there is a dog lying at his feet. His right hand points to a group of three figures under the left arch, one of whom holds a scroll. In the right arch stand two soldiers in mail, one of whom is holding a sword. In front of the two soldiers is a kneeling figure presenting a scroll. This miniature is worn and defaced by use.

The miniatures of the 'causae' are all rectangular and on backgrounds of blue diaper with white relief tracery. There are borders in bands of pale pink outlined with black, relieved by faint white tracery and with a square of gold in each corner. The text followinging the miniatures is introduced by large decorated floriated initials. These are in colours of red, pale blue, pale lake, and burnished gold on backgrounds of blue with white tracery. Two of these initials are anthropomorphic, visible on folios 93v and 151v.

The illuminated initials can be found on the following folios: 93v, 116v, 135r, 143v, 145v, 148r, 151v, 158v, 161v, 164v, 168r, 180r, 191r, 195v, 198v, 203r, 216v, 220v, 223v, 224v, 227r, 229r, 237r, 261r, 273r, 277r, 284v, 293v, 297v, 299r, 302v, 304r, 313v, 317r, 347r, 348v, 355v, and 357r.

There is evidence of contemporary repairs throughout.

Each folio, recto and verso, has been lined and ruled.

Paraphs are in red and blue, with rubrics in red. Litterae notabiliores are red and blue with red and blue penwork. Initials are stroked in red.

In addition to the central text and the gloss, there are some interlineal and marginal annotations, as well as maniculae and faces, throughout
