Rabanus Maurus
Rabanus Maurus Magnentius (c. 780 – 4 February 856), also known as Hrabanus or Rhabanus, was a Frankish Benedictine monk, the archbishop of Mainz in Germany and a theologian. He was the author of the encyclopaedia De rerum naturis ("On the Natures of Things" or "On the Universe"). He also wrote treatises on education and grammar and commentaries on the Bible. He was one of the most prominent teachers and writers of the Carolingian age, and was called "Praeceptor Germaniae," or "the teacher of Germany." On the Roman calendar (Martyrologium Romanum, 2001, pp. 126f.), he is celebrated on 4 February and listed as 'sanctus,' though the online version of the Catholic Encyclopedia of nearly a century earlier lists him as 'beatus.'
Life
Rabanus was born of noble parents in Mainz. The date of his birth remains uncertain, but in 801 he received a deacon's order at Fulda in Hesse, where he had been sent to school. In the following year, at the insistence of Ratgar, his abbot, he went together with Haimon (later of Halberstadt) to complete his studies at Tours. He studied there under Alcuin, who in recognition of his diligence and purity gave him the surname of Maurus, after the favourite disciple of Benedict, Saint Maurus. Returning to Fulda two years later, he was entrusted with the principal charge of the school, 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. At this period he probably compiled his excerpt from the grammar of Priscian, a popular text-book during the Middle Ages. According to Butler's Lives of the Saints, Rabanus ate no meat and drank no wine.
