Collectio canonum I in Clm 12612
The manuscript Munich, StB Clm 12612 came to the Staatsbibliothek from the monastery of St. Pancratius at Ranshofen. It contains extracts from the writings of Bernold of Constance, and is, as Ian Stuart Robinson recognized, closely related to his circle. On fol. 118r–119v (RA01) are canons which are also found in the collections that Giorgio Picasso entitled Ambrosiana I and Ambrosiana II. They are in older cores of those collections, the surviving versions of the which have been augmented with excerpts from the Tripartita of Ivo of Chartres. See the descriptions of those collections above. A second block of texts, on fol. 120r–125v (RA02), contains the first 54 canons 169 of the second version of the Tarraconensis. Only canons 25 and 31 of the series of texts in the Tarraconensis are missing in the Ranshofen manuscript. Rudolf Pokorny informed me that a group of texts from the collection of Regino of Prüm are found in this manuscript and that they are almost the same as can be found in the Ms Sankt Gallen, Stiftsbibliothek 676, which contains the Swabian recension of the 74T compiled by Bernold of Constance.
