He was a key member of the Carolingian Renaissance and an important figure during the many reforms of the church under Charlemagne, as well as almost certainly the author of the Libri Carolini,[1] "much the fullest statement of the Western attitude to representational art that has been left to us by the Middle Ages".
During his trip to Rome in 786, Theodulf was inspired by the centres of learning there, and sent letters to a large number of abbots and bishops of the Frankish empire, encouraging them to establish public schools.
[6] Charlemagne recognized Theodulf's importance within his court and simultaneously named him Bishop of Orléans (c. 798) and abbot of many monasteries, most notably the Benedictine abbey of Fleury-sur-Loire.
Capitula ad presbyteros parochiae The first capitulary was a reminder to the priests of his diocese of the importance of manual labour, studying, prayer and chastity.
