The Geometric Unconscious: A Century of AbstractionInspired by the Sheldon Museum of Art's holdings in geometric abstraction, this book introduces adventurous new thinking about a visual approach that has captivated both artists and viewers for more than a century. Four richly illustrated essays explore the European genesis of geometric abstraction, its translation into an American context, and its current direction, charting the style's aesthetic, intellectual, and social implications.
