Several stories also feature knights struggling to stave off the advances of voluptuous women, including "Yder", the Lancelot-Grail Cycle, "Hunbaut", and "The Knight of the Sword". The Green Knight parallel in these stories is a King testing a knight as to whether or not he will remain chaste in extreme circumstances. The woman he sends is sometimes his wife (as in "Yder"), if he knows that she is unfaithful and will tempt other men; in "The Knight of the Sword" the king sends his beautiful daughter. All characters playing the Green Knight's role kill unfaithful knights who fail their tests.
