"Proportio" examines the ways in which we experience proportion in our lives and the complex universe in which we live. Proportion-not only a question of numbers, but of balance-emerges in this volume as a universal human pursuit. Throughout the course of known human history, the knowledge of proportions has been applied across civilizations for thousands of years. The sophisticated knowledge of sacred geometry was considered closely linked to secretive spiritual wisdom and religious traditions. This volume elegantly connects these ancient notions to works by artists such as Le Corbusier, Albrecht Dürer, Sol LeWitt, Anselm Kiefer, Tomas Saraceno, Marina Abramovi c, Anish Kapoor and Michaël Borremans. Beautifully produced and presenting objects drawn from art, nature, physics, economics, history, science, music, medicine and many other sources, "Proportio" uncovers the natural patterns that are used to organize and create the material world.
