Gawain features frequently in modern literature and media. Modern English depictions of him are heavily influenced by Malory, though characterizations are inconsistent. Alfred Tennyson adapts episodes from Malory to present Gawain as a worldly and faithless knight in his Idylls of the King .    Similarly, T. H. White 's novel The Once and Future King follows Malory, but presents Gawain as more churlish than Malory's torn and tragic portrayal.  In contrast, Thomas Berger 's Arthur Rex portrays Gawaine as open-minded and introspective about his flaws, qualities that make him the Round Table's greatest knight.  Though he usually plays a supporting role, some works feature Gawain as the main character. Vera Chapman 's The Green Knight and Anne Crompton's Gawain and Lady Green offer modern retellings of Sir Gawain and the Green Knight .  Gwalchmai is the protagonist in Gillian Bradshaw 's Celtic-tinged Hawk of May and its sequels.  An aged Gawain is one of the central characters in Kazuo Ishiguro 's novel The Buried Giant . 
It begins with the New Year's celebration in Camelot.
