Note 280 — BOOK XIII.
William Robson translation
It is Matthew Paris who furnishes us with information relative to this attempt to persuade St. Louis. This is the chronicler that throws most light upon the events of that period; such as the council of Lyons, the quarrel of Frederick and the pope, and the crusade of the king of France. We also find some details in William of Nangis, in Joinville, and in the Ecclesiastical Annals of Raynaldi.
