Architecture needs mechanisms that allow it to become connected to culture. It achieves this by continually capturing the forces that shape society. This book is a graphic guide to ornaments in the twentieth century. It unveils the function of ornament as the agent for specific affects, dismantling the idea that ornament is applied to buildings as a discrete or non-essential entity. Each case exploits specific synergies between the exterior and the interior, constructing an internal order between ornament and material. These internal orders produce expressions that are contemporary, yet whose affects are resilient in time.
