Which legendary English hero is depicted in the picture?

Guy of Warwick, or Gui de Warewic, is a legendary English hero of Romance popular in England and France from the 13th to 17th centuries. The story of Sir Guy is considered by scholars to be part of the Matter of England.

The core of the legend is that Guy falls in love with the lady Felice ("Happiness"), who is of much higher social standing. In order to wed Felice he must prove his valour in chivalric adventures and become a knight; in order to do this he travels widely, battling fantastic monsters such as dragons, giants, a Dun Cow and great boars. He returns and weds Felice but soon, full of remorse for his violent past, he leaves on a pilgrimage to the Holy Land; later he returns privately and lives out his long life as a hermit.
