Charley Peters reviews the Agnes Martin retrospective at Tate Modern, on view through October 11, 2015.

Peters notes that "Despite any of the vulnerability implied by the narratives surrounding her paintings, [the exhibition] is a vast, comprehensive survey of [Martin's] robust and relentless vision, best viewed by spending time with her paintings and not by dwelling for too long on the explanations of why they may have been made… The power of Martin’s paintings is in their quiet declaration of their own existence; they are barely visible but resolutely present."
