Mirrors of Salt publishes the proceedings of the First International Congress on the Anthropology of Salt, which took place at the Alexandru Ioan Cuza University in Iasi (Romania). The impact of salt on the development of human communities, from the Neolithic to the present, has generated a huge number of specialized studies. However, scientific research has become so atomized that the primordial importance of the mineral has been lost, creating a need for a holistic, comprehensive vision of the dimensions generated by salt. This can only be achieved through anthropology. The anthropology of salt encompasses the entirety of human behavior, i.e. cognitive, spiritual, pragmatic, and social reactions to salt, and provides a holistic view of its role in the evolution of human communities. The anthropology of salt thus brings salt studies from an ancillary position to an autonomous discipline. The papers in this volume are organized into six sections: theory, archaeology, history, ethnography/ ethnoarchaeology/ethnohistory, linguistics, and literature. Topics include salt in Greek and Roman antiquity, as well as from Cameroon, Georgia, Ireland, Italy, Mexico, Moldova, Mongolia, Nigeria, Peru, Romania, Spain, Sudan, Syria, Ukraine, the USA and Venezuela. The congress was organized within the project The Ethnoarchaeology of the Salt Springs and Salt Mountains from the Extra-Carpathian Areas of Romania, financed by the Government of Romania (CNCS – UEFISCDI) (2011-2016). Its theoretical novelty and geographical range render Mirrors of Salt a unique study of the world’s most-used non-metallic mineral.

This volume containing papers given at a 2008 international colloquium in Romania takes a range of approaches to the study of salt production and its role in past societies. Ranging from the Neolithic to traditional methods of salt extraction in the present day, a particular focus in on central and eastern Europe, whilst ethnographic, archaeological, historical, textual and linguistic methods are adopted.

Different Times? Archaeological and environmental data from intra-site and off-site sequences brings together seven papers from Session II-8 of the XVIII UISPP Congress (Paris, 4-9 June 2018). The session questioned temporal correlations between intra-site and off-site data in archaeology-related contexts. The word 'site' describes here archaeological sites or groups of sites - usually settlements - that have undergone research in recent years and produced information on the duration and timing of human presence. Comparison with evidence from geomorphological and paleoenvironmental research conducted at various distances from settlements gives some interesting results, such as 'missing' occupation periods, distortions in human presence intensity through space as well as time, variability in explanations concerning the abandonment of settlements, etc. Examples presented here highlight: first, discrepancies between time records within built areas used for living and the surrounding lands used for other activities (cultivation, herding, travelling, etc); second, discrepancies produced by the use of different 'time markers' (ie. chronostratigraphy of archaeological layers or pottery evolution on the one hand, sedimentary or pollen sequences on the other hand). Although improving the resolution of individual data is essential, the authors argue that the joint and detailed examination of evidence produced together by human and natural scientists is more important for reaching a reliable reconstruction of past people's activities. Both the session and the volume stem from the Working Group 'Environmental and Social Changes in the Past' (Changements environnementaux et societes dans le passe) in the research framework of the Cluster of Excellence 'Dynamite' (Territorial and Spatial Dynamics) of the University Paris 1-Pantheon-Sorbonne (ANR-11-LABX-0046, Investissements d'Avenir).

Salt is an invisible object for research in archaeology. However, ancient writings, ethnographic studies and the evidence of archaeological exploitation highlight it as an essential reference for humanity. Both an edible product and a crucial element for food preservation, it has been used by the first human settlements as soon as food storage appeared (Neolithic). As far as the history of food habits (both nutrition and preservation) is concerned, the identification and the use of that resource certainly proves a revolution as meaningful as the domestication of plants and wild animals. On a global scale, the development of new economic forms based on the management of food surplus went along an increased use of saline resources through a specific technical knowledge, aimed at the extraction of salt from its natural supports. Considering the variety of former practices observed until now, a pluralist approach based on human as well as environmental sciences is required. It allows a better knowledge of the historical interactions between our societies and this "white gold", which are well-known from the Middle-Ages, but more hypothetical for earlier times. This publication intends to present the most recent progresses in the field of salt archaeology in Europe and beyond; it also exposes various approaches allowing a thorough understanding of this complex and many-faceted subject. The complementary themes dealt with in this book, the broad chronological and geographical focus, as well as the relevance of the results presented, make this contribution a key synthesis of the most recent research on this universal topic.
