Monasticism is a form of religious life in which participants renounce worldly activities to dedicate themselves primarily to spiritual matters, living in small communities subject to a set of rules and isolated from the secular world. Christian monasticism, which originated at the end of the 3rd century in Egypt and North Africa, spread to different parts of Europe in the 6th century. However, it was not until the Middle Ages that monastic communities became one of the most powerful institutions in Europe. Monasteries and convents played a very important role not only as centers of spirituality but also as focal points of economic, technological and cultural activity. This multiplicity of activities carried out alongside their religious, social and political roles make monasteries spaces that can be studied from very different perspectives and that unfailingly provide essential information about our history. This first of two titles originates from an international conference that took place in Barcelona in January 2024, which sought to examine different aspects related to monastic life in the past and to promote and disseminate the results obtained in the latest studies undertaken within the framework of monastic complexes and their environments. These include contributions and multidisciplinary studies from archaeological, bioanthropological and/or documentary perspectives. Specialists from different disciplines present developments on the topic of monasticism from different fields of study, such as zooarchaeology, bioanthropology, palaeopathology, archaeology, history, documentary disciplines, archives, cultural heritage, etc. Volume 1 concentrates on health and lifeways within monastic communities, focusing on palaeopathological information providing insights into physical wellbeing and, in particular, the presence and significance of disabled individuals and evidence for longterm health and dental issues. A variety of scientific methods of analysis are applied to cemetery populations from monasteries and nunneries of different periods to examine both causes of and contributions to the death of individuals, the composition of communities and the treatment of the dead. Studies of assemblages of faunal remains from monastic complexes consider how faunal analysis can help interpret the role of domestic species.

He is a specialist in zooarchaeology and taphonomy, focusing on the procurement of animal foods, past animal hunting and husbandry economies and examining the role of animals in past societies beyond serving as food, employing, in particular, neotaphonomic research, geometric morphometrics, isotopic analysis, animal palaeopathological and forensic taphonomic analysis. Carme Rissech is a senior lecturer in the Department of Basic Medical Sciences, Universitat Rovira i Virgili, Reus, Spain and holds a PhD from the University Autonomous of Barcelona. She is an expert in the fields of palaeoanthropology and forensic anthropology, employing interdisciplinary approaches combining human bone analysis with documentary sources, histological and biomolecular analysis and medicine. Jordi Nadal is a reader in History and Archaeology at the University of Barcelona, from which he obtained his PhD. He specializes in zooarchaeology and taphonomy, focusing on various aspects of past humananimal relationship. He is also interested in the application of neotaphonomic models to better understand the origin of small prey accumulations in prehistoric archaeological sites. Philip Banks is a retired lecturer in English as a Foreign Language at the University of Barcelona, now an independent researcher in medieval history. He obtained a PhD in archaeology and history from Nottingham University, where he studied urban transformations between the 4th and 13th centuries in Catalonia, especially the city of Barcelona. He has translated archaeological and historical texts from Spanish and Catalan to English and collaborated with museums and archaeological services on projects concerning medieval documents and the archaeological interpretation of historical sources, especially as regards townscapes and the periurban zones of medieval cities. 100 b/w photos and line illustrations
