Over the last three decades, Jacqueline Humphries (b.1960) has, through an innovative painterly process, challenged the limits of abstraction. She has produced a body of work that reaches beyond modernism, Abstract Expressionism, and abstraction as we know it. Multi-layered in application, Humphries challenges the viewer to interact with her painting in diverse ways, inviting new approaches to looking and being with a work. Expertly analysing the ways in which Humphries has challenged convention and placed abstract painting at the centre of our twenty-first century visual environment, Frances Guerin's illuminating text reveals an artist at the peak of her powers.
