Likely composed after Aye d’Avignon, this continuation of the Nanteuil cycle chronicles the adventures of Gui, the son of Aye and Garnier, who was made a standard-bearer at Charlemagne’s court. Here Gui is soon accused of murder by members of the ever-pernicious Ganelon clan lead by Hervieu of Lyon, compelling him to flee court. Charlemagne and Hervieu pursue and lay siege to Gui and his love interet, the Princess Aiglentine of Gascony at Nanteuil, where Ganor and Aye come to his rescuse and the traitor, Hervieu, is exposed and killed in single combat with Gui.
In one of the manuscripts, the Venice Marciana Fr. X, the text contains a nine-hundred and forty-three line prologue in Franco-Italian, contrasting with the standard Old French text of Gui which follows.
