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.
