Agnes Martin's career spanned over seven decades, with a profile that has skyrocketed since the 2015-17 major exhibition at Tate Modern, London that travelled globally to great acclaim. Though a major influence on Minimalist painters, Martin saw her own work more closely related to Abstract Expressionism, her paintings being 'meditations on innocence, beauty, happiness and love.' This much-anticipated reissue of Martin's exhibition manager and close friend Arne Glimcher's highly-acclaimed book presents 130 of her paintings and drawings alongside her previously unpublished writings and lecture notes. Glimcher's illuminating introduction, his personal memories of visits to Martin at her studio, and their correspondence throughout her career, reveal many insights into the artist's life and work.
