The Roman de Fergus is an Arthurian romance written in Old French probably at the very beginning of the 13th century, by a very well educated author who named himself Guillaume le Clerc (William the Clerk). The main character is Fergus, the son of Soumilloit (a name corresponding to Sorley or Somerled; Scottish Gaelic: Somhairle), a rich but old-fashioned farmer and a noble Arthurian woman who rises to become the best knight of King Arthur.
