Proclaiming that “now my heart is sore” (Line 14), the poet/speaker contemplates the gorgeous display of swans on the lake at Coole Park. He reflects on how reassuringly permanent nature is when set against the crazy confusion of his own life and how, across the nearly 20 years since he remembers first seeing the swans, his heart has been deeply and often wounded. Inevitably, Yeats scholars, among them Richard Ellman, introduce Yeats’s own on-again, off-again relationship with the tempestuous Irish political activist and stage actress Maud Gonne (1866-1953) as a parallel to this reference. Yeats admired Gonne for years and even proposed marriage to her on multiple occasions despite her very public and very messy divorce. In 1916, then in his fifties, Yeats proposed to Gonne’s 20-something daughter, who also turned him down.

Although that heartache could provide the context for the poet/speaker’s meditation on the sorrows of his heart, scholars such as Masami Nakao have also suggested that the poet’s melancholy extends well beyond the reach of Yeats’s private sorrows. The poem is more a response to Yeats’s broader historical context, specifically to World War I and the ignominious defeat of a generation of patriotic efforts to secure Ireland’s political freedom from England.

At the time of the poem’s composition, Europe was engulfed in a war that, by 1916, seemed to be both brutal and unending, with millions of casualties, soldiers and civilians, and much of Europe reduced to an apocalyptic wasteland. In addition, the poem reflects Yeats’s disillusionment over the disastrous failure of the Irish Free State movement, which culminated in a bloody five-day debacle in spring 1916 that came to be called the Easter Uprising. Since his twenties, Yeats had been a passionate advocate for Irish culture, introducing Celtic myths and folktales into his own poetry. The poet/speaker’s world-weariness and keen sense of despair then is certainly informed by this historical context.
