Faërie came close to vanishing altogether during the First World War, thanks to [the] associative confusion of the pre-war era, childhood, and fairy-tales. Yet Tolkien did not regard fairies as childish, and he was not writing nursery-tales, but an epic history of a world through faëry eyes. In her galloping survey of fairy traditions, Troublesome Things, Diane Purkiss says that ‘The Western Front made the fairy aesthetic seem both desperately necessary and hopelessly anachronistic.’ Tolkien’s account of the tragic decline of the Elves acknowledges that their time is over but urges the desperate necessity of holding on to the values they represented. Far from being a sign that the war had no impact on Tolkien, his commitment to Faërie was a consequence of it. ‘A real taste for fairy-stories was wakened by philology on the threshold of manhood,’ he wrote later, ‘and quickened to full life by war.’
