Erec

Sir Erec, the son of King Lac, is a Knight of the Round Table in Arthurian legend. He features in numerous Arthurian tales (notably the Post-Vulgate Cycle), but he is most famous as the protagonist in Chrétien de Troyes' first romance, Erec and Enide. Because of Erec and Enide‘s relationship to the Welsh Geraint and Enid, Erec and Geraint are often conflated or confused.

The Arthurian romance by Chrètien de Troyes that examines the tension between love and the duties of chivalry (defense of others, maintenance of the knightly reputation, and exercise in arms).
