Beginning with the Old Testament, then followed by two historical works, The Antiquities and The Jewish War, by Flavius Josephus who lived in the first century AD, then Josephus an Encyclopedia of the middle ages, by Isidore, who lived in the sixth century in Spain. Next is a collection of medical works, and then the New Testament. The final of the long works is a Chronicle of Bohemia by Cosmas from Prague.
Additionally there are some short works. The first, before the picture of the Heavenly City, is a work on penitence. Following the Devil portrait, is a work about exorcising evil spirits.
