Mordred, Arthur’s great opponent and eventual vanquisher, is the dark and sinister character, the man of mysterious origin and of blighting influence, moving gloomily through the drama. By some said to be Arthur’s own son, a child of sin and crime, and by others said to be the son of King Lot and Arthur’s sister, his life was miraculously preserved when the king ordered the slaying of all children born on May-day, in the hope of removing the infant who, as Merlin had prophesied to him, “shall destroy you and all the knights of your realm”; and thereafter he played a malignant part in the drama. If ill-news were to be borne to the king, Mordred bore it; were trust to be violated, Mordred violated it; were knights to be betrayed, Mordred was the spy and informer. Left to rule the land in Arthur’s absence, he usurped the throne; left to guard Guinevere, he carried her away and attempted to force her in marriage; an outcast, he became Arthur’s deadliest rival and fulfilled Merlin’s prediction. It was he, and not the racial antagonist, who was destined to give the final blow to the Order that the king had established. Tennyson, following the suggestion of the chroniclers, has sharply contrasted Mordred with Lancelot, whose enemy he was, not so much because Lancelot was sinful, as because his sin gave him the opportunity of striking a blow against Arthur’s favourite knight. He was Lancelot’s rival, too, his secret and cunning rival, for the love of Guinevere. All the pictures we have of Mordred are adverse; he is the “passing envious” man who hates all more successful than himself, the man who “laid his ear beside the doors,” who was “always sullen”; the tale-bearer, whose narrow face and thin lips pictured the petty, spiteful spirit within; the man whose shield was blank and unblazoned, but who “Like a subtle beast Lay couchant with his eyes upon the throne, Ready to spring, waiting a chance: for this He chill’d the popular praises of the King With silent smiles of slow disparagement; And tampered with the Lords of the White Horse, Heathen, the brood by Hengist left; and sought To make disruption in the Table Round Of Arthur, and to splinter it into feuds Serving his traitorous end; and all his aims Were sharpen’d by strong hate for Lancelot.” [Illustration: _Photo: R.
