The figures of Michael Robartes and Owen Aherne appear throughout the writing of the great Irish poet W.B. Yeats, featuring in his poems, short fictions, dialogues and as authorities in notes to his work. Bringing together into one volume published and unpublished writings featuring these two enigmatic figures, W.B. Yeats's Robartes-Aherne Writings traces their history and the development of Yeats's mystical thought that culminated (twice) in the publication of his visionary work A Vision (1925, 1937).

Including reproductions of manuscript and notebook pages as well as transcriptions and extracts from a wide range of Yeats's mystical writings and substantial commentary and annotation throughout, this book is an essential resource for scholars of Yeats's thought, his stylistic evolution and the esoteric influences on modernist writing in the early 20th century.
