 Although some historical elements are interwoven into the story, Matthew had little reliable information to go on and much of the narrative is therefore fictitious.Of particular interest is that it features the oldest surviving account of the "Constance" tale-type.The king of York tries to marry his daughter; when she refuses, she is abandoned in the woods, where Offa finds her, and he marries her, but later, when he is at war, through a forged letter, she is again abandoned in the woods with her children, and she, Offa, and the children are reunited many years later.
