This was the most popular of the various masses which were often included in Books of Hours which were taken to church as well as used at home. The Mass of the Virgin was celebrated in church every Saturday, the day dedicated to Mary. Opening with a small miniature of St Luke painting the Virgin, the text is surrounded by a full border with the Tree of Jesse. The preceding leaf, now lost, probably contained a full-page miniature facing this page and constituting another double spread.
