This Book of Hours according to the custom of the Roman Church contains a pre-bound fragment of an Italian Book of Hours, including the Athanasian Creed and the prayer O domina mea sanctissima. The actual manuscript begins with the beginning of the Gospel of John, accompanied by a picture of John on Patmos. Mary in the Gloriole to O Intemerata and Obsecro te is followed by the Hours of the Virgin with a cycle of pictures from the Annunciation (Lauds) to the Flight into Egypt (Compline). The beginnings of the prayers for Advent with three readings and the picture of the Death of Mary, followed by David Praying in front of the Penitential Psalms, Litany and requiem (orants and pleurants in front of the coffin), close the cycle. Of special quality, clearly distinguished from the Dutch pictures, are the three miniatures of the Annunciation, the Crucifixion, and the benefactor, kneeling in front of Saint Bernhard. Characteristic features, in addition to the style of the figures (generous folds in the garments), are the patterns of the floor, the backgrounds, the corner ornamentation of the frames, as well as the filigree tendrils with leaves heightened with gold, together with the blue angels which carry the initials “by”. These return, as in the three miniatures, in the Book of Hours Walters 239 (cf. Roger S. Wieck, The Book of Hours in Medieval Art and Life, London 1988,, no. 87, fig. 110), whose Flemish provenance (Bruges) must also be considered in the attribution of the miniatures from LM 11 to the group of manuscripts from Ypres. The miniature of the Visitation of Mary, which opens the Hours of the Virgin with sequences of antiphons and psalms as well as three readings, exemplifies the characteristic style of all following miniatures, both in terms of composition and colouring. Above all, the Dutch style can be recognized in the small faces lacking in differentiation.
