The Marriage of Yeats and Georgie Hyde-Lees
What happened
Following his final, definitive romantic rejection by both Maud Gonne and her daughter Iseult, a desperate fifty-two year old W.B. Yeats married the much younger Georgie Hyde-Lees. Only days into an initially awkward marriage, Georgie began attempting automatic writing to distract and comfort her deeply depressed husband. This unexpected spiritualist experiment quickly blossomed into an elaborate, years-long system of psychological and philosophical communication that fascinated the poet.
Literary impact
Georgie's extensive automatic writing provided the direct raw material for Yeats's profound philosophical prose work 'A Vision'. This unique mystical and romantic partnership completely re-energized Yeats's creative output, directly inspiring his greatest, most complex late modernist poetry collections, including 'The Tower' and 'The Winding Stair'.
