Breviarium canonicorum regularium monasterii sanctae crucis mortariensis
A late medieval Latin breviary, a manuscript prayer book for canons regular, copied in 1470 for use at the monastery of Holy Cross in Mortara. The picture is a historiated initial with a bearded saint in a green robe holding a book and a long sword, set in a red and blue illuminated letter with gold leaf and green foliage, and a designer might take its jewel-toned palette and interlaced border ornament.
