The latest volume in this renowned research-level series focuses on Yeats's occult reading and his collaborative ventures with Dorothy Wellesley. It draws upon his study of the writings and drawings of Leonardo da Vinci, which inflects the iconography of 'Among School Children'. Closely examining the making of Yeats's work (including the presentation of a new unfinished 'play for dancers'), the volume turns from Japanese influences on his work to his immediate influence in Japan via Yone Noguchi, as well as to his legacy in the elegiac poems of W.H. Auden and Seamus Heaney. It collects the work of new and distinguished scholars and critics: Richard Allen Cave, Wayne K. Chapman, Sally Connolly, Anthony Cuda, David Dwan, Deborah Letizia Ferrelli, Colin McDowell, Neil Mann, Phillip L. Marcus, Edward Marx, James Pethica, Derek Roper, Rory Ryan, Deirdre Toomey, and Wim van Mierlo.
