Covers a tumultuous period in WB Yeats' public and personal life, beginning with the acrimonious collapse of Maud Gonne's marriage to Major MacBride, and encompassing the fiery disputes in the Abbey Theatre as it changed from an amateur society into a professional company. This fourth volume of The Collected Letters shows Yeats in the full throes of professional life and focuses particularly on his engagement with the Irish drama movement. The editors John Kelly and Ronald Schuchard have provided a superb narrative introduction to a volume that includes letters both to and from Yeats and an appendix documenting the tumultuous history of the Abbey Theatre that is a valuable study in itself. Kelly and Schuchards detailed annotations are thorough but never pedantic, the letters themselves are unusually fascinating, and the whole provides a sense of both sweep and detail. An exemplary marriage of literary pleasure and scholarly brilliance, The Collected Letters will be a work of abiding interest to both general readers and specialists.
