The Encyclopaedia of Late Antique Art and Archaeology seeks to fill a significant gap in historical research by placing art and archaeology at the forefront of late Roman and late antique studies. Recognising the need for a comprehensive and accessible reference, this work moves beyond the traditional focus on ‘early Christian archaeology’ to adopt a broader perspective. It highlights the dynamic interplay of Christianity, Judaism and Islam, challenging outdated notions of a fully Christianised Late Antiquity. Organised into six sections – architecture and iconography, artefacts and material evidence, urbanism and rural landscapes, regional and ethnic diversity, and key issues and debates – the encyclopaedia offers a structured, in-depth exploration of the field. With contributions from leading scholars, it synthesises archaeological discoveries to challenge narratives of decline, instead presenting Late Antiquity as an era of transformation and cultural fusion.
