Gottfried's work is regarded, alongside Wolfram von Eschenbach's "Parzival" and the "Nibelungenlied", as one of the great narrative masterpieces of the German Middle Ages. He is probably also the composer of a small number of surviving lyrics. His work became a source of inspiration for Richard Wagner's opera "Tristan und Isolde" (1865).

Document 4: Lohengrin (opera): Lohengrin, WWV 75, is a Romantic opera in three acts composed and written by Richard Wagner, first performed in 1850.

It is part of the Knight of the Swan tradition.
Document 5: Parzival: Parzival is a medieval German romance written by the poet Wolfram von Eschenbach in Middle High German. The poem, commonly dated to the first quarter of the 13th century, centers on the Arthurian hero Parzival (Percival in English) and his long quest for the Holy Grail following his initial failure to achieve it.
Document 6: Parsifal: Parsifal (WWV 111) is an opera in three acts by German composer Richard Wagner. It is loosely based on "Parzival" by Wolfram von Eschenbach, a 13th-century epic poem of the Arthurian knight Parzival (Percival) and his quest for the Holy Grail (12th century).

Document 8: Richard Wagner: Wilhelm Richard Wagner ( ; ] ; 22 May 181313 February 1883) was a German composer, theatre director, polemicist, and conductor who is primarily known for his operas (or, as some of his later works were later known, "music dramas"). Unlike most opera composers, Wagner wrote both the libretto and the music for each of his stage works. Initially establishing his reputation as a composer of works in the romantic vein of Weber and Meyerbeer, Wagner revolutionised opera through his concept of the "Gesamtkunstwerk" ("total work of art"), by which he sought to synthesise the poetic, visual, musical and dramatic arts, with music subsidiary to drama. He described this vision in a series of essays published between 1849 and 1852. Wagner realised these ideas most fully in the first half of the four-opera cycle "Der Ring des Nibelungen" ("The Ring of the Nibelung").
Document 9: Le donne rivali: Le donne rivali is an intermezzo in two acts by composer Domenico Cimarosa with an Italian libretto by a now unknown poet. It is speculated that Giuseppe Petrosellini may have been the author of the libretto. The opera premiered at the Teatro Valle in Rome during Carnival in 1780. The original choreography was created by Alberto Cavos, the original costumes by Antonio Dian, and the original scenery by Domenico Fossati. Music critics particularly admire the final quintet that closes the opera. In recent years, "Le donne rivali" has been occasionally revived and recorded. In 1991, the Juilliard Opera Center intertwined the work with Mozart's unfinished opera "Lo sposo deluso", which shares the same libretto, to make one large work.
