Question: Are Salome and Sir Gawain and the Green Knight both Germanic in background?

full_context: Document 1: Salome (opera): Salome, Op. 54, is an opera in one act by Richard Strauss to a German libretto by the composer, based on Hedwig Lachmann's German translation of the French play "Salomé" by Oscar Wilde. Strauss dedicated the opera to his friend Sir Edgar Speyer.
Document 2: Ariadne auf Naxos: Ariadne auf Naxos ("Ariadne on Naxos"), Op. 60, is an opera by Richard Strauss with a German libretto by Hugo von Hofmannsthal. Combining slapstick comedy and consummately beautiful music, the opera's theme is the competition between high and low art for the public's attention.
Document 3: Sir Gawain and the Green Knight: 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.
Document 4: A Modern Salome: A Modern Salome is a lost 1920 silent film comedy directed by Leonce Perret and starring Hope Hampton. It was produced and distributed by Metro Pictures. The film is based on the Oscar Wilde play "Salome".
Document 5: Salome's Last Dance: Salome's Last Dance is a 1988 film by British film director, Ken Russell. Although most of the action is a verbatim performance of Oscar Wilde's 1893 play "Salome", which is itself based on a story from the New Testament, there is also a framing narrative written by Russell himself. Wilde (Nickolas Grace) and his lover Lord Alfred Douglas (Douglas Hodge) arrive late on Guy Fawkes Day at their friend's brothel, where they are treated to a surprise staging of Wilde's play, public performances of which have just been banned in England by the Lord Chamberlain's office.
Document 6: King Arthur and King Cornwall: "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".
Document 7: Lady Bertilak: 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.
Document 8: Green 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.
Document 9: Elektra (opera): Elektra, Op. 58, is a one-act opera by Richard Strauss, to a German-language libretto by Hugo von Hofmannsthal, which he adapted from his 1903 drama "Elektra". The opera was the first of many collaborations between Strauss and Hofmannsthal. It was first performed at the Dresden State Opera on 25 January 1909. It was dedicated to his friends Natalie and Willy Levin.
Document 10: Sword of the Valiant: 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.
Document 11: Samson and Delilah (opera): Samson and Delilah (French: "Samson et Dalila" ), Op. 47, is a grand opera in three acts and four scenes by Camille Saint-Saëns to a French libretto by Ferdinand Lemaire. It was first performed in Weimar at the Grossherzogliches (Grand Ducal) Theater (now the Staatskapelle Weimar) on 2 December 1877 in a German translation.
Document 12: Le Chevalier à l'épée: 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.
Document 13: Gawain and the Green Knight (film): 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".
Document 14: Richard Strauss: Richard Georg Strauss (11 June 1864 – 8 September 1949) was a leading German composer of the late Romantic and early modern eras. He is known for his operas, which include "Der Rosenkavalier", "Elektra", "Die Frau ohne Schatten" and "Salome"; his Lieder, especially his "Four Last Songs"; his tone poems, including "Don Juan", "Death and Transfiguration", "Till Eulenspiegel's Merry Pranks", "Also sprach Zarathustra", "Ein Heldenleben", "Symphonia Domestica", and "An Alpine Symphony"; and other instrumental works such as "Metamorphosen" and his Oboe Concerto. Strauss was also a prominent conductor in Western Europe and the Americas, enjoying quasi-celebrity status as his compositions became standards of orchestral and operatic repertoire.
Document 15: Also sprach Zarathustra (Strauss): Also sprach Zarathustra , Op. 30 (Thus Spoke Zarathustra or Thus Spake Zarathustra) is a tone poem by Richard Strauss, composed in 1896 and inspired by Friedrich Nietzsche's philosophical novel of the same name.
