“Politics,” the last of W. B. Yeats’s Collected Poems (Richard Finneran’s New Edition), ends with the poet's wish for fulfillment of sexual desire and love: “But O that I were young again / And held her in my arms.” Yeats wrote this poem in May 1938, eight months before his death. In another poem, “A Prayer for Old Age,” written in 1934, the poet prays that he “may seem . . . A foolish, passionate man.” In these and other poems of Yeats’s last years, “lust and rage” really seem to “dance attendance upon [his] old age” and “spur [him] into song” (“The Spur”). This paper is an attempt to understand the last years of Yeats’s life and poetry in terms of sexuality and love. The first part of this paper discusses the Steinach operation which Yeats underwent in 1934, when he was 68 years old. Although it is uncertain that the operation had brought the poet the expected “second puberty,” it seems to have had an psychologically positive effect upon his writing of poetry. During the last five years after the operation, Yeats wrote almost fifty poems, which is surprising number considering his old age and precarious health. In this part of the paper, the present writer reads some poems in which the poet's feeling and thought about sexuality and love in these final years of his life are most clearly expressed: “A Prayer for Old Age,” “The Spur,” “The Wild Old Wicked Man,” and the sequence of “Supernatural Songs.” After the operation Yeats met Margot Ruddock, Dorothy Wellesley, Ethel Mannin, and Edith Shackleton Heald, all of them being young, pretty, and intelligent women. They were poets (Ruddock and Wellesley), a novelist (Mannin), and a journalist (Heald). The second part of this paper deals with the poet’s meetings with these women, and reads the poems which are based upon, and reveal the nature of, their relations: “Margot,” “Sweet Dancer,” “A Crazed Girl,” “To Dorothy Wellesley,” and “The Three Bushes.”
