The eminent poet and scholar Kathleen Raine, leading exponent of "the learning of the imagination," brings together all her essays on Yeats (some never before printed) covering many aspects of the traditions and influences that informed his great poetry. In saluting Raine's "magnificent achievement in this rich and learned book," Professor Augustine Martin of University College Dublin states that she "irradiates [Yeats] and every corner of his work. Her unique and unanswerable contribution to Yeatsian criticism is to establish his authority as an immensely learned poet and thinker in the tradition of Plato and the Eternal Philosophy." Contains over 140 illustrations.
