In addition to the definitions of the elements that make up each operational sequence, the volumes will also include a final part providing a comparative synthesis that makes it possible to sketch the historical evolution of the techniques in antiquity. This synthesis will offer visual representations of the operational sequences described in the first part of the volume, and will outline, as far as possible, the chronological and geographical variations.
This part, which by definition will be the most ephemeral part of the volume, will present an overview of current knowledge for each production process and offer a sketch of on-going debates at the moment of writing. It will therefore avoid the more strictly economic or social questions (status, size and specialization of the work-force; the impact of the work on them; differences between domestic and commercial forms of production, etc.), though the elements brought together in the synthesis will be of help in redacting editing other specialized works approaching economic questions from a technical angle.
