The Lay of Havelok the Dane (1280)

According to Wikipedia: "Havelok the Dane, also known as Havelok or Lay of Havelok the Dane, is a Middle English chivalric romance. The story, however, is also known in two earlier Anglo-Norman versions. Most scholars place Havelok the Dane at the end of the thirteenth century, between 1280 and 1290.[1] The name “Havelok” also has many variations in spelling, and can found as “Haveloc” or “Havelock.” Early versions also use the Welsh form of "Abloec."
