... I am (these last 6 months) immersed in a v. different poet who I think great – Charles Williams: the two volumes of his Arthurian poems Taliessin and The Region of the Summer Stars. Inexcusably difficult, as I always told him, but here there really is something behind the difficulty – that something wh. we all need most in literature at present & wh. I wd. call opaque splendour – thick, rich, solid, heavy – porphyry, gold diamond.
