The astronomical-computist collective work produced in Cologne c. 805 contains eight diagrams and texts relating to the writings of Isidore of Seville and those of the Venerable Bede. The latter is concerned with the calculation of the phases of the moon and the four seasons and also contains speculations about the construction of the world which is held together by the four elements.

Folios 83v and 84r show the phases of the moon and the four elements.
