Sir Thomas Malory's collection of medieval romances traces the rise of Arthur from his mysterious boyhood to his coronation and the establishment of the Round Table. Guided by the wizard Merlin, Arthur pulls the sword from the stone, proves his royal lineage, and unites Britain by subduing rebellious kings and Saxon invaders. The narrative unfolds through distinct branches, focusing on the magical origins of Camelot, the quest for the Holy Grail, the tragic romance of Lancelot and Guinevere, and the adventures of various knights such as Gareth and Balin. Central to the work is the moral code of chivalry, which demands that knights defend the weak, honor ladies, and seek truth.
However, human flaws, pride, and forbidden passions gradually undermine the unity of the realm. As the fellowship faces internal strife and magical curses, the foundations of Camelot begin to fracture. The epic moves toward a somber decline, hinting at the final dissolution of the Round Table and the passing of Arthur into legend.
