This is the first of a fourteen-volume edition of Yeats’s work issued under the general editorship of Richard Finneran and George Mills Harper. A necessary read for Yeats devotees, Seamus Heaney writes, “All readers of Yeats will need this book; when they open it they will feel a surprise like that experienced by St. Brendan the Navigator and his crew when they disembarked upon an island that turned out to be the back of a dormant sea monster.”
