This leaf, and three others in the Morgan, are all that remain of a once splendid copy of Gregory's Decretals. The frontispieces for Books IV and V may yet turn up. This leaf was the beginning of Book III, dealing in part with the participation of the lay congregation in the Mass, the subject of the large miniature. Within the initial U (of ut) a monk receives his tonsure, while in the border below is an unusual depiction of people swimming. The Master of 1328 was one of the finest Bolognese artists before Niccolò da Bologna. His name is derived from the register he made in that year for the Haberdashers of Bologna (Bologna, Museo Civico Medievale, MS. 633).
