A publication on the role of the hortus conclusus, or the enclosed garden, as an instrument of negotiation between tradition and modernity in Italian landscape design. Beginning with the Pompeiian peristyle garden, then moving onto Renaissance-era and modern translations, the series of analytic drawings traces the enduring significance of the hortus conclusus throughout disparate temporal and regional contexts within Italy and its role in establishing continuity. Though radically different in their functions, compositions, and locations, the following gardens engage with concepts of enclosure and boundary to explore the theory and design of landscape within the defined space of the garden, both alluding to and questioning the idea of the hortus conclusus.
