 Other forms of the legend are to be found in the story of Doolin's mother in "Doon de Mayence", the English romance of "Sir Triamour", in the story of the mother of Octavian in "Octavian the Emperor", in the German folk book "Historie von der geduldigen Königin Crescentia", based on a 12th-century poem to be found in the "Kaiserchronik", and the English "Erl of Toulouse" (c. 1400).In the last-named romance it has been suggested that the story gives the relations between Bernard I, Count of Toulouse, son of the Guillaume d'Orange of the Carolingian romances, and the empress Judith, second wife of Louis the Pious—who were indeed charged with adultery and purged themselves by an oath and an offer for trial by combat, although the historical situation has been embellished with romantic incident.In Marcel Proust's "In Search of Lost Time" (1913–27), the narrator remembers a magic lantern he had in his room, in Combray, that showed the image of Golo riding his horse towards Genevieve's castle.
