How do we create the new from the old? The Architecture of Influence explores this fundamental question by analyzing a broad swath of twentieth-century architectural works—including some of the best-known examples of the architectural canon, modern and postmodern—through the lens of influence. The book serves as both a critique of the discipline’s long-standing focus on "genius" and a celebration of the creative act of revisioning and reimagining the past. It argues that all works of architecture not only depend on the past but necessarily alter, rewrite, and reposition the traditions and ideas to which they refer. Organized into seven chapters—Replicas, Copies, Compilations, Generalizations, Revivals, Emulations, and Self-Repetitions—the book redefines influence as an active process through which the past is defined, recalled, and subsequently redefined within twentieth-century architecture.
