These two long essays make up, with The Descent of the Dove, Charles Williams' principal theological writing. With these books and with The Figure of Beatrice the reader is as fully equipped as possible for studying the religious thought of this brilliant poet, novelist, essayist and historian. Charles Williams was one of the finest -- not to mention one of the most unusual -- theologians of the twentieth century. His mysticism is palpable -- the unseen world interpenetrates ours at every point, and spiritual exchange occurs all the time, unseen and largely unlooked for. His novels are legend, and as a member of the Inklings, he contributed to the mythopoetic revival in contemporary culture.
