This book details Professor Moevs' findings of Italian Sigillata pottery at the Cosa excavation site, an invaluable source of information on Roman colonization, urbanism, and daily life since excavation began in 1948. The exceptional external conditions at Cosa preserved archaeological levels of natural strata from the early and late first century B.C., allowing documentation of the earliest phases of Italian Sigillata, which quickly became a major empire-wide export. This widely used pottery went through many changes in color and presentation during the Roman Colonial era, in response to various transitions and developments in Roman society. The research presented in this volume of the series from the American Academy in Rome will be of great interest to the archaeological and classical studies community.
