Circulation has emerged as a vital area of study in humanities and social science fields such as cultural anthropology, transnational history, and social studies of science and technology. Networks, infrastructure, and materiality more generally have been used to understand how society and cultural experience are constituted through movement. In architectural history, the lens of circulation promises new ways of conceptualizing two fundamental dichotomies: that between center and periphery and that between elite and popular culture. First of all, as they question the assumed isomorphism between culture and territory that continues to underpin much of architectural discourse, accounts of circulation offer a new approach to globalization in architectural history. Rather than casting the non-West as derivative of an original modernity in the West, they reframe modernity as fundamentally transient and thus constantly reconfigured as it travels. Secondly, by looking at how new kinds of knowledge and building travel and proliferate, such analyses problematize categorical oppositions between vernacular and authored production and instead reveal how asymmetries of power and cultural difference are both produced and undermined by circulation.
