Photographs, newspaper cuttings, postcards, drawings, and slides: on entering the studio of Eduardo Souto de Moura, winner of the Pritzker Prize 2011, one is confronted with a variety of images on the walls that engage in a dialogue. How do these photos, drawings, and illustrations impact his design practice? "Floating Images: Eduardo Souto de Moura's Wall Atlas" uses this question as an opportunity to examine the architect's visual universe. He has added images from his extensive collection of drawings and project sketches and reorganized them in this atlas. Essays by Pedro Bandeira, Eduardo Souto de Moura, Diogo Seixas Lopes, and Philip Ursprung round off the publication and provide a contextualization in terms of the history of art and images.
