In page Rabanus Maurus:

"

Returning to Fulda, in 803 he was entrusted with the principal charge of the abbey school,[1] which under his direction became one of the most preeminent centers of scholarship and book production in Europe, and sent forth such pupils as Walafrid Strabo, Servatus Lupus of Ferrières, and Otfrid of Weissenburg. It was probably at this period that he compiled his excerpt from the grammar of Priscian,[2] a popular textbook during the Middle Ages. According to Alban Butler's Lives of the Saints, Rabanus ate no meat and drank no wine.
