Raoul de Houdenc (or Houdan) c.1165–c.1230 was the French author of the Arthurian romance Meraugis de Portlesguez and possibly the Vengeance Raguidel. Modern scholarship suggest he is probably to be identified with one Radulfus from Hodenc-en-Bray. Raoul de Houdenc was esteemed as a master poet in the ranks of Chrétien de Troyes by Huon de Méry (Tournoi de l'antéchrist, 1226). http://en.wikipedia.org/wiki/Raoul_de...
