Written by Agobard of Lyons

A letter addressed to Count Mathfrid of Orléans, one of the most influential men at Louis the Pious' court during the thirteen years between 815, when he is first attested at Louis the Pious's court, and 828, when he was deposed.

Its aim is to to criticize the corruption rife at the Carolingian royal court. However, it also contains important elements on the notion of just rule under God's authority.
