Why could Tolkien not be more like Sir Thomas Malory, asked [Edwin] Muir, in the third Observer review of those cited above, and give us heroes and heroines like Lancelot and Guinevere, who ' knew temptation, were sometimes unfaithful to their vows,' were engagingly marked by adulterous passion? But T.H. White had already considered that paradigm, was indeed rewriting it at the same time as Tolkien in The Once and Future King; and he had seen the core of Malory's work not in romantic vice but in the human urge to murder. In White the poisonous adder that provokes the last disastrous battle is no adder but a harmless grass-snake, and the flash of the sword which brings on the two armies is not natural self-defense but natural blood-lust, creating a continuum from cruelty to animals to world wars and holocausts. Malory has to be rewritten to encompass a new view of evil.
