Havelok the Dane

"If any excuse is needed for recasting the ancient legend of Grim the fisher and his foster-son Havelok the Dane, it may be found in the fascination of the story itself, which made it one of the most popular legends in England from the time of the Norman conquest, at least, to that of Elizabeth. From the eleventh to the thirteenth centuries it seems to have been almost classic; and during that period two full metrical versions - one in Norman-French and the other in English - were written, besides many other short versions and abridgments, which still exist."
