Lionel (Arthurian legend)

Lionel (Lionello in Italian) is a character in the cyclical prose tradition of the Arthurian legend in which he is a Knight of the Round Table and one of the sons of King Bors of Ganis (Gannes, Ganys, Gaun[n]es) and his wife, Queen Evaine. Lionel was introduced in the Lancelot-Grail cycle as the younger brother of Bors de Ganis, a double cousin of Lancelot, and (depending on the work) either a cousin or nephew of Lancelot's younger half-brother Hector de Maris.

Albeit not relatively well-known today, Lionel was a popular character during the medieval era, notably including a major fascination by the king Edward III of England. Outside of the Arthurian literature, he is also the subject of a traditional ballad. He should not be confused with Gawain's son also named Lionel, nor with a Lyonnel character in Perceforest.
