Lupus Servatus, also Servatus Lupus (c. 805 – c. 862), in French Loup, was a Benedictine monk and Abbot of Ferrières Abbey during the Carolingian dynasty, who was also a member of Charles the Bald's court and a noted theological author of the 9th century. He is sometimes regarded as the first humanist of the Early Middle Ages because of the quality of his literary style, his love of learning, and his work as a scribe and textual critic.
Lupus was born into an influential family within the Archdiocese of Sens. Many of his family held influential positions in the Church or court. His father was Bavarian and his mother Frankish. He assumed the nickname of Servatus in commemoration of his miraculous escape from danger either in a serious illness or on the battlefield. He began his education at the Abbey of Saints Peter and Paul in Ferrières-en-Gâtinais under St. Aldric, then abbot of the monastery. Here he was educated in the trivium and quadrivium.
Lupus was not fond of the required learning but developed a passion for Classical studies. Abbot Aldric saw fit to send him to deepen his theological education at the Abbey of Fulda under Rabanus Maurus. Spending years in study and writing he developed a reputation as a scholar. Rabanus made use of his pupil, having him translate and compose bodies or works. During his residence at Fulda (c. 830–36) he became an intimate friend and disciple of the learned Einhard, whose Vita Karoli magni he was one of the first to read and praised it because of its style (epist. 1, 5). Lupus had written a letter to Einhard expressing his admiration and asked for a loan of Einhard's secular works (this would become a common practice of Lupus). His opinion was that education should be esteemed and intended not for a certain purpose, but as a good of its own value (epist. 1, 5). He was interested therefore not only in Christian but also in pagan classical authors and even those who did not belong to the reading canon of the Carolingian schools, such as Suetonius, of whom he was one of very few readers in the early Middle Ages, and Cicero, whose works he seems to know almost in their entirety, not only his better known rhetorical writings, and whom he mentions and cites very often. He borrowed manuscripts from Einhard (epist. 1, 6) and from the library of the monastery of Fulda and corresponded therefore with Abbot Markward (epist. 10, 4; 91, 4).
