The Lais are dedicated to an unknown king, who is identified as Henry II.
The origin of the lais has been the subject of much discussion.
The Lais which may be definitely attributed to Marie are: Guigemar, Equitan, Le Feene, Le Bisclavret (the werewolf), Les Deux amants, Laustic, Chaitivel, Lanval, Le Chevrefeuille, Milon, Yonec and Eliduc. The other similar lays are anonymous except the Lai d'Ignaure by Renant and the Lai du cor of Robert Biket, two authors otherwise unknown.
See Die Fabeln der Marie de France (1898), edited by Karl Warnke with the help of materials left by Eduard Mall; and Die Lais der Marie de France (2nd ed., 1900), edited by Karl Warnke, with comparative notes by Reinhold Kohler; the two works being vols.
For an analysis of the Lais see Revue de philologie francaise, viii.
