Libeaus Desconus is a 14th-century Middle English version of the popular "Fair Unknown" story. Its author is thought to be Thomas Chestre. The story matter displays strong parallels to that of Renaut de Beaujeu's "Le Bel Inconnu"; both versions describe the adventures of Gingalain, the son of King Arthur's knight Gawain and a fay who raises him ignorant of his parentage and his name. As a young man, he visits Arthur's court to be knighted, and receives his nickname; in this case Sir Libeaus Desconus, before setting forth on a series of adventures which consolidate his new position in society. He eventually discovers who is his father, and marries a powerful lady.
