Atlante digitale delle strutture preistoriche: focolari, forni e installazioni da fuoco

The aim of the paper is to illustrate a sharing project of an on-line digital atlas of prehistoric structures, where scholars can share the products of their research or their discoveries, enrich their mind of knowledge through several updated comparisons, analyze any details of construction and related stratigraphy, identify main types, open discussions within the frame of interpretation of ancient features. Actually, particularly related to this meeting, the early phase of the project regards published protohistoric ovens and fireplaces, proposing a basic form to fill with information and documentation as well as introducing a general discussion on models and processes. Instead of proposing a classification the paper deals with indicating characters and markers recognizable in the archaeological context as well as building a conceptual map related to the ontology of use of fire in prehistory.
