A new book based on JRR Tolkien’s notes and unfinished manuscripts has just been published, The Fall of Arthur. Primarily, it’s based on Tolkien’s unfinished long narrative poem (in Old English alliterative style) about Arthur that he abandoned in the the 1930s (perhaps because of his work on The Hobbit. Here’s an official overview:
The Fall of Arthur, the only venture by J.R.R. Tolkien into the legends of Arthur King of Britain, may well be regarded as his finest and most skilful achievement in the use of the Old English alliterative metre, in which he brought to his transforming perceptions of the old narratives a pervasive sense of the grave and fateful nature of all that is told: of Arthur’s expedition overseas into distant heathen lands, of Guinevere’s flight from Camelot, of the great sea-battle on Arthur’s return to Britain, in the portrait of the traitor Mordred, in the tormented doubts of Lancelot in his French castle.
Unhappily, The Fall of Arthur was one of several long narrative poems that he abandoned in that period. In this case he evidently began it in the earlier nineteen-thirties, and it was sufficiently advanced for him to send it to a very perceptive friend who read it with great enthusiasm at the end of 1934 and urgently pressed him ‘You simply must finish it!’ But in vain: he abandoned it, at some date unknown, though there is some evidence that it may have been in 1937, the year of the publication of The Hobbit and the first stirrings of The Lord of the Rings. Years later, in a letter of 1955, he said that ‘he hoped to finish a long poem on The Fall of Arthur’; but that day never came.
