Book excerpt: Land Air Sea: Architecture and Environment in the Early Modern Era positions the long Renaissance and eighteenth century as being vital for understanding how many of the concerns present in contemporary debates on climate change and sustainability originated in earlier centuries. Traversing three physical and intellectual domains, Land Air Sea consists of case studies examining how questions of environmentalism were formulated in early modern architecture and the built environment. Addressing emergent technologies, indigenous cultural beliefs, natural philosophy, and political statecraft, this book aims to recast our modernist conceptions of what buildings are by uncovering early modern epistemologies that redefined human impact on the habitable world.
