Charles Williams' two cycles of poems, Taliessin through Logres and The Region of the Summer Stars, have been described as the major imaginative work about the Grail of the 20th century, praised for their spiritual reality and complex patterns of sound and haunting rhythms. In this new edition David Llewellyn Dodds collects together Williams' earlier poems on Arthurian themes, which both grew into and gave way to the final versions. This collection, which Charles Williams called The Advent of Galahad, was never published as such, though individual poems did appear in print. There are also later fragments, designed to form a sequel to The Region of the Summer Stars, which appear for the first time. Besides the publication of this new material, this edition aims to introduce new readers to William's lyrical pieces.
