Published in 1903, Gawayne and the Green Knight is a modern-language retelling of Sir Gawain and the Green Knight, a 14th-century verse romance following a young knight of the Round Table. During Christmas celebrations, a mysterious, entirely green knight presents a challenge to King Arthur's court: that any may strike the stranger a single blow with his green axe, provided he assent to receiving the same a year later. Gawayne accepts the challenge, and its unexpected outcome leads to a great test of his courage and knighthood. A significant addition to this version is the Lady Elfinhart, whose back-story and romance with Gawayne are tightly interwoven with the plot.
