The work is an adaptation of the story of Charlemagne's battles in Spain and the adventures of his nephew, the paladin Orlando (Roland), including the tale of his mortal duel with Ferraguto and his ultimate death at Roncesvalles.
An adaptation of the Pseudo-Turpin material also occurs in the anonymous Franco-Venetian epic L'Entrée d'Espagne (c. 1320; the author is thought to be from Padua).
The author begins with Charlemagne's intention to subdue Spain and then give the crown to his nephew, the count Orlando.
In the end, the author tells the famous episode of the treachery of Gano of Maganza, envious of the glory of the family of Orlando.
In the great battle of Roncesvalles, the main characters die, but are vindicated by Charlemagne, who is finally able to conquer Spain and to condemn the fraudulent Gano.
