Focusing on the concept of changing places, the essays in this anthology discuss processes of constitution, stabilization, and transformation of worlds of knowledge, covering a wide range of thematic and historical perspectives from the European Middle Ages to the 21st century. Objects as eclectic as church buildings, panel paintings, etchings, pieces of narrative and dramatic literature, motion pictures and TV genres serve to illustrate how access to as well as the interpretation of stocks of knowledge is determined by spatial orders and their oscillations.
