This manuscript, produced in the first half of the 9th century in Fulda, contains two astronomical texts: several excerpts of the Aratus latinus and the Aratea by Germanicus with explanatory scholia, illustrations of the 34 constellations and a (now removed) drawing of the entire night sky. The Aratea, based on the astronomical didactic poem by Aratus of Soli, served as illustrative source for the astronomical background knowledge required for teaching the computus (calculating the date of Easter) at the school of the Fulda Monastery.
