This collection of critical essays focuses on how material is transformed, revised, swallowed whole, plagiarized or in any other way appropriated in order to address pressing and timely questions regarding architectural influence. It charts new territory within this still unexplored yet highly topical area of study by establishing a shared vocabulary with which to discuss, or contest, the workings of influence as a vital and progressive aspect of architectural discourse. Written by a group of rising scholars in the field of architectural history and criticism, the essays cover a range of architectural subjects but they are linked in their investigations of how architects engage with their predecessors, and in what ways we can productively begin to analyse the workings of influence.
