This chapter examines the position of Sulis Minerva and her sanctuary within the wider networks of empire and how Roman imperialism was negotiated in different ways throughout the site’s history. It starts by arguing that the foundation of the sanctuary in the Flavian period should be read primarily as an imperialist act designed to proclaim ownership of an indigenous sacred site; this is supported by the iconography datable to this period, especially the pediment of the temple. While this emphasis on imperial domination faded in later periods, Aquae Sulis continued to be a place where individuals, especially soldiers, used the worship of Sulis, and in particular epigraphy linking the deity to the imperial cult, to structure their identity and relationship to the emperor specifically and broader conceptions of empire more generally. The possibility that some of the votives from the sacred spring reflect similar concerns is also explored. Comparative material from other sites in Britain and Gaul is woven into the discussion throughout, and used to argue for a broad understanding of the pervasiveness of emperor-worship and the imperial cult in provincial religion.
