This chapter considers the influence of two women mystics on Yeats’ work: his wife George Yeats, and Iseult Gonne. It details George’s extensive esoteric knowledge and traces her spiritual collaboration with Yeats back to 1915. The chapter considers the dissonance between Yeats’ creative debt to brilliant, spiritual women like George, Moina Mathers[aut]Mathers, Moina, and the Gonnes, and his comparatively reductive opinions on women in phases fourteen and sixteen of A Vision. The chapter analyses the significance of placing Blake in a phase consisting of mostly female examples. It also details A Vision’s implication of Blake’s madness in the context of Yeats’ 1890s Blake criticism, which refuted such insinuations. This chapter also represents the first analysis of Iseult Gonne’s impact on Yeats’ earlier mystic text, Per Amica Silentia Lunae[aut]Yeats, W.B.works, prose, and her representations of visionary experience. Finally, the chapter considers the influence of William Sharp’s and Fiona Macleod’s Blake readings on the ContrariesContrariesBlake’s system of binary underlying A Vision, representing the potential queer and trans implications of Yeats’ system.
