characterize his middle work as supple and muscular in its rhythms and sometimes harshly modernist, while others find the poems barren and weak in imaginative power. Yeats's later work found new imaginative inspiration in the mystical system he began to work out for himself under the influence of spiritualism. In many ways, this poetry is a return to the vision of his earlier work. The opposition between the worldly-minded man of the sword and the spiritually minded man of God, the theme of The Wanderings of Oisin, is reproduced in A Dialogue Between Self and Soul. Some critics hold that Yeats spanned the transition from the nineteenth century into twentieth-century modernism in poetry much as Pablo Picasso did in painting; others question whether late Yeats has much in common with modernists of the Ezra Pound and T. S. Eliot variety. Modernists read the well-known poem "The Second Coming" as a dirge for the decline of European civilisation, but it also expresses Yeats's apocalyptic mystical theories and is shaped by the 1890s. His most important collections of poetry started with The Green Helmet (1910) and Responsibilities (1914). In imagery, Yeats's poetry became sparer and more powerful as he grew older. The Tower (1928), The Winding Stair (1933), and New Poems (1938) contained some of the most potent images in twentieth-century poetry. Yeats's mystical inclinations, informed by Hinduism, theosophical beliefs and the occult, provided much of the basis of his late poetry, which some critics have judged as lacking in intellectual credibility. The metaphysics of Yeats's late works must be read in relation to his system of esoteric fundamentals in A Vision (1925). Works Legacy Yeats is commemorated in Sligo town by a statue, created in 1989 by sculptor Rowan Gillespie. On the 50th anniversary of the poet's death, it was erected outside the Ulster Bank, at the corner of Stephen Street and Markievicz Road. Yeats had remarked on receiving his Nobel Prize that the Royal Palace in Stockholm "resembled the Ulster Bank in Sligo". Across the river is the Yeats Memorial Building, home to the Sligo Yeats Society. Standing Figure: Knife Edge by Henry Moore is displayed in the W. B. Yeats Memorial Garden at St Stephen's Green in Dublin. There is a blue plaque dedicated to Yeats at Balscadden House on the Balscadden Road in Howth. This was his cottage home from 1880-1883. In 1957 the London County Council erected
