This book presents a selection of the images collected by Mexican architect Luis Barragán (1902–1988) as part of a reference archive that he displayed on a lectern in the living room of his home. In an ever-changing arrangement of pictures, Barragán’s thinking was made visual. Because it was a personal archive from which the architect simply added or removed images over time, the 170 currently registered pictures are all that can provide us today with a kaleidoscopic insight into Barragán’s mind, itself a myriad network of personal relationships, professional influences, and formal obsessions. The publication is the manifestation of a project by Roger Willems and Mark Manders.
