On the Governance of the Palace
De Ordine Palatii
Hincmar of Reims · 806 – 882
Written for a young king in the last year of Hincmar's life, describing how Charlemagne's court was run — the officers, the twice-yearly assemblies, who advised on what — and arguing that a king who rules without counsel is a tyrant and that the bishops are owed a hearing.
