This book considers the philosophical and intellectual backgrounds and the historical sources that lie behind David Jones's poetry. By consulting the texts that Jones drew on either directly or indirectly in the creation of his poetry, the author has attempted to prepare the ground for a sympathetic understanding of all Jones's work. The present volume makes extensive use of the books which Jones possessed and annotated. It also considers a large number of unpublished drafts and letters and includes a long passage from In Parenthesis that was eventually deleted by the poet. The book discusses all Jones's published work and considers the major themes and preoccupations that absorbed him.
