poet, novelist, and theological writer. His novels, which have been described as supernatural thrillers, include War in Heaven (1930), Descent into Hell (1937), and All Hallows Eve (1944). Of his theological writings the most important was The Descent of the Dove (1939). His literary criticism included a study of Dante, The Figure of Beatrice (1943). He wrote several verse plays on religious themes, but his most original poetic achievement is perhaps his cycle on the Arthurian legend. Taliessin through Logres (1938), and The Region of the Summer Stars (1944), afterwards reissued in one volume (1974) together with Arthurian Torso, a study of Williams's poetry by his friend C. S. Lewis.
