This unique Middle English text, not previously published, of the immensely popular story of Charlemagne's Spanish wars and defeat at Roncevaux, has only recently been discovered. It is one of the earliest prose romances, pre-dating Sir Thomas Malory's Morte D'Artur by more than a decade. This version testifies to a distinctive British tradition of the Charlemagne story. The manuscript's history locates the text in Lancastrian and regional politics of the mid-fifteenth century.
