Gawain is often portrayed as a formidable, courteous, and also a compassionate warrior, fiercely loyal to his king and family. He is a friend to young knights, a defender of the poor, and as "the Maidens' Knight", a defender of women as well. 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. Gawain appears in English, French and Celtic literature as well as in Italy where he appears in the architecture of the north portal in the cathedral of Modena, constructed in 1184.
