Rabanus Or Hrabanus (Mauris), a German theologian, born in Mentz about 776, died at Winkel in 856. He was educated in the Benedictine convent of Fulda, and continued his studies in Tours under Alcuin, who gave him the surname of Maurus in honor of St. Maurus. He returned to Fulda in 804, founded there the first public convent school in Germany, and labored especially for the spread and improvement of the German language. He wished to free the German church from the influence of Rome, and succeeded in introducing the rule that the clergy should only preach in the native tongue. He has also the merit of having given a new impetus to Biblical research by requiring the study of the original tongue of the New Testament. These innovations drew upon him the displeasure and suspicion of the clerical party, and though finally elevated to the rank of an abbot, he laid down his office in 842 to live in the priory of St. Peter; but in 847 he resumed teaching, and was consecrated archbishop of Mentz. Among his works is Glossaria Latino-theo-disca, which is now an important monument of the earliest phase of the German language. He wrote also De Universo, De Arte Gram-matica Prisciani, and several other theological treatises.

His works (exclusive of the Glossaria) were published by Calvonerius (6 vols. fol., Cologne, 1627).
