This volume is about the related concepts of house and household in Classical Antiquity and about how those concepts were materialised at different times and in different places through the physical structure of the house itself. More importantly, it considers how that physical structure and its associated concepts can help to address major questions about social structure, patterns of cultural interaction, continuity and change in Classical Antiquity. The chronological scope is long, ranging from the tenth century bce (the Early Iron Age) down to the fourth century ce. The geographical spread is equally broad, stretching from modern Turkey in the north east to Tunisia in the south-west, taking in Greece and Italy on the way. My goal, however, is not to present a comprehensive account of everything that is known about housing and households within this span. Instead, the individual chapters constitute case studies based on evidence from specific regions during particular periods. In each instance discussion begins by seeking to understand the appearance, organisation or representation of housing through archaeological, iconographic and/or textual sources, but the aim is much broader. The size, form and decoration of an individual domestic structure are determined by a variety of factors: environment, technology and availability of resources impose broad parameters. Nonetheless, an equally important role is played by culturally specific expectations about the kinds of architecture and decoration that are appropriate, about how and where different activities should be carried out, and by and with whom.
