Since 2006 the Balnéorient team has been studying ancient (from the Early Hellenistic period on) to contemporary collective baths in the Eastern Mediterranean. This federative program aimed at examining the various aspects of this hugely attested social practice in an area that had never been, so far, taken as the focal point of a survey on both the longue durée and this wide geographical context. The present book includes 63 articles, case studies and syntheses, together with a common bibliography. These articles examine the bathing phenomenon within the broader Middle Eastern context and allow for a panoramic view of the phenomenon that underlines its complexity and highlights the striking wealth of bath-related heritage in this region. The diachronic approach, in particular, suggests a history of the bathing phenomenon across times that differs from the one which was presented elsewhere as being made of peaks, such as the Roman and Ottoman periods, and stagnant phases or declines, such as the end of Antiquity or the modern era. On the contrary, this book demonstrates the extreme richness and diversity of the Middle East bath-related heritage, in all periods and in all countries in which we conducted our study.
