One of the most important Irish novelists of the twentieth century, Kate O’Brien (1897–1974) was also a pioneer of women’s writing. In a career that spanned almost fifty years, nine novels, nine plays, two travelogues, and copious criticism, O’Brien rebelled against the narrow nationalism andrestrictive Catholicism prevalent in independent Ireland. In this highly original approach to O’Brien’s work, Davison traces the influence of three leading Spanish writers—Jacinto Benavente, Miguel deCervantes, and Teresa of Avila. O’Brien’s lifelong fascination with Spanish literature and culture offered an oblique way of resisting the Catholic and conservative imperatives of the Irish Free State. In a series of close comparative readings, Davison identifies the origin of O’Brien’s creative disinhibition and ultimately situates her within a tradition of dissident Irish women writers.
