The central section (f. 10r-42r) comprises the last 3 gatherings of what were originally 13 gatherings of commentaries on the gospel and epistle readings for the temporal cycle compiled from sermons of French Dominican scholars Durandus of St. Pourçain and Jacobus of Lausanne. The closing section (f. 42r-46v) includes tables and lists for Biblical, classical, and Mideastern dates; the position in the third house of all the planets; the significance of each house; the power and virtues of the signs of the zodiac on the parts of the body, regions, plants, stones, and stars; the virtues of each house; the movement of each house; the properties of each planet; the properties of each sign; and the sun's position in the zodiac arranged by month.
