Historia Caroli Magni

The Historia Caroli Magni ('History of Charles the Great'), also known as the Historia Karoli Magni et Rotholandi ('History of Charles the Great and Roland') or the (Pseudo-)Turpin Chronicle, is a 12th-century Latin chronicle consisting of legendary material about Charlemagne's campaigns in Spain. The chronicle states it was written by Charlemagne's contemporary Turpin, Archbishop of Reims, but it was found out as a medieval forgery. The work was extremely popular, and served as a major source of material on Charlemagne in chronicles, fiction and iconography throughout Medieval Europe. The miracles of the flowering lances and the death of Ferracutus appear on the windows of Chartres cathedral.
