Extending the figure-ground visual paradox to a fundamental architectonic problem – that of the reciprocity between a wall and a window – this book by Mauricio Pezo and Sofia von Ellrichshausen reflects on the intersection between painting and architecture. If a window is inherently a subtraction of a wall’s surface but also an infill with a “view” beyond it, a painting is as much a flat, opaque surface as the illusion of space beyond. Containing over 1,000 works, including paintings, sketches, and line drawings, this alphabetical catalogue presents a broad examination of the Chilean duo’s practice to date. The book also includes an essay by the authors and an index of the artworks.
