Gawain (pronounce /ˈgɔːwɪn/ or /gəˈweɪn/; also called Gwalchmei, Gawan, Gauvain, Walewein, etc.) is King Arthur's nephew and a Knight of the Round Table who appears very early in the Arthurian legend's development. He is one of a select number of Round Table members to be referred to as the greatest knight, most notably in Sir Gawain and the Green Knight. He is almost always portrayed as the son of Arthur's sister Morgause (or Anna) and King Lot of Orkney and Lothian, and his brothers are Agravain, Gaheris, Gareth, and Mordred. In some works he has sisters as well. Gawain is often portrayed as a formidable but brash warrior, fiercely loyal to his king and family. He is a friend to young knights, a defender of the poor, and a consummate ladies' man. In some works, his strength waxes and wanes with the sun; in the most common form of this motif, his might triples by noon, but fades as the sun sets. His knowledge of herbs makes him a great healer, and he is credited with at least three children: Florence, Lovell, and Gingalain, the last of which is also called Libeaus Desconus or Le Bel Inconnu, the Fair Unknown. In later Welsh Arthurian literature, Gawain is considered synonymous with the native champion Gwalchmei.
