Open Archaeology invites manuscripts for the Special Issue on Reconsidering the Chaîne Opératoire: Towards a Multifaceted Approach to the Archaeology of Techniques. This issue aimed at re-discussing the theory and methods of technological studies, considering their diachronic application to different contexts and materials. In particular, we wish to focus on the study of objects as a formal (standardised) language, which could be used to outline a horizontal narrative of artefacts making as well as that of human communities.
