Sir Gawain and the Green Knight (Middle English: "Sir Gawayn and þe Grene Knyȝt") is a late 14th-century Middle English chivalric romance.
 It is one of the best known Arthurian stories, with its plot combining two types of folklore motifs, the beheading game and the exchange of winnings.
 The Green Knight is interpreted by some as a representation of the Green Man of folklore and by others as an allusion to Christ.
 Written in stanzas of alliterative verse, each of which ends in a rhyming bob and wheel, it draws on Welsh, Irish, and English stories, as well as the French chivalric tradition.
 It is an important poem in the romance genre, which typically involves a hero who goes on a quest which tests his prowess, and it remains popular to this day in modern English renderings from J. R. R. Tolkien, Simon Armitage, and others, as well as through film and stage adaptations.
Sword of the Valiant: The Legend of Sir Gawain and the Green Knight is a 1984 dramatic fantasy film starring Miles O'Keeffe, Trevor Howard, Lila Kedrova, Cyrielle Clair, Leigh Lawson, Peter Cushing, and Sean Connery.
 The film is loosely based on the poem "Sir Gawain and the Green Knight", written in the late 14th century, but the narrative differs substantially.
 This was the second time director Stephen Weeks had adapted the traditional tale into a movie.
 His first try was "Gawain and the Green Knight", starring singer Murray Head, and released in 1973.
"The Marriage of Sir Gawain" is an English Arthurian ballad, collected as Child Ballad 31.
 Found in the Percy Folio, it is a fragmented account of the story of Sir Gawain and the loathly lady, which has been preserved in fuller form in the medieval poem "The Wedding of Sir Gawain and Dame Ragnelle".
 The loathly lady episode itself dates at least back to Geoffrey Chaucer's "Wife of Bath's Tale" from "The Canterbury Tales".
 Unlike most of the Child Ballads, but like the Arthurian "King Arthur and King Cornwall" and "The Boy and the Mantle", "The Marriage of Sir Gawain" is not a folk ballad but a song for professional minstrels.
Lady Bertilak is a character in the medieval poem "Sir Gawain and the Green Knight".
 She is ordered by her husband, the Green Knight, or Lord Bertilak, to test Sir Gawain's purity.
Le Chevalier à l'épée ('The Knight with the Sword') is an earlier-thirteenth-century Old French romance, surviving in only one manuscript.
 It is the earliest romance to focus specifically on the Arthurian knight Sir Gawain and its plot is in some important respects similar to that of "Sir Gawain and the Green Knight".
 The poem presents a satirical or cynical take on ideas of chivalry.
"King Arthur and King Cornwall" is an English ballad surviving in fragmentary form in the 17th-century Percy Folio manuscript.
 An Arthurian story, it was collected by Francis James Child as Child Ballad 30.
 Unlike other Child Ballads, but like the Arthurian "The Boy and the Mantle" and "The Marriage of Sir Gawain", it is not a folk ballad but a professional minstrel's song.
 It is notable for containing the Green Knight, a character known from the medieval poems "The Greene Knight" and the more famous "Sir Gawain and the Green Knight"; he appears as "Bredbeddle", the character's name in "The Greene Knight".
The Green Knight is a character in the 14th-century Arthurian poem "Sir Gawain and the Green Knight" and the related work "The Greene Knight".
 His true name is revealed to be Bercilak de Hautdesert in "Sir Gawain", while "The Greene Knight" names him "Bredbeddle".
 The Green Knight later appears as one of Arthur's greatest champions in the fragmentary ballad "King Arthur and King Cornwall", again under the name "Bredbeddle".
 In "Sir Gawain and the Green Knight", Bercilak is transformed into the Green Knight by Morgan le Fay, a traditional adversary of King Arthur, in order to test his court.
 In "The Green Knight" he is transformed by a different woman for the same purpose.
 In both stories he sends his wife to seduce Gawain as a further test.
 "King Arthur and King Cornwall" portrays him as an exorcist and one of the most powerful knights in Arthur's court.
Opera buffa (] ; plural: "opere buffe"; Italian for "comic opera") is a genre of opera.
 It was first used as an informal description of Italian comic operas variously classified by their authors as "commedia in musica", "commedia per musica", "dramma bernesco", "dramma comico", "divertimento giocoso".
Gawain and the Green Knight is a 1973 film directed by Stephen Weeks, and starring Murray Head as Gawain and Nigel Green in his final theatrical film as the Green Knight.
 The story is based on the medieval English tale "Sir Gawain and the Green Knight".
Gerald Morris (October 29, 1963– ) is an American author.
 Morris is known for his series of stories for preteen and teen readers based in the Middle Ages during the time of King Arthur.
 Collectively called "The Squire's Tales", the books blend retellings of traditional Arthurian Myths, such as Sir Gawain and the Green Knight and Tristan and Iseult, with original plotlines.
 The books at the start of the series focus somewhat on Sir Gawain, but primarily on Terence, an original character and Gawain's squire.
 Although the two characters' roles are minor in some books, they remain throughout series, whereas main characters from the other books are only mentioned or reappear briefly later in the series.
