Much of the existing analysis of women in O’Casey’s plays concentrates on the women in his earlier work; this chapter examines the representation of younger women in O’Casey’s later plays, revealing how O’Casey presented a strongly contemporary feminist outlook which sought to re-position his audience’s understanding of female sensibility. The chapter analyses the way in which, by questioning theatrical form and critiquing patriarchal control of women, O’Casey enabled experimentalism in dramatic form to go hand in hand with a willingness to evolve and develop a progressive expression of female sexuality.
