Preistorico o non-preistorico? Approccio tecno-funzionale per la definizione degli obiettivi di produzione e utilizzo delle pietre focaie dall’insediamento rupestre di rivolta (Ginosa – Taranto)

The Ginosa archaeological storage reorganization, has made it possible to isolate and study the lithic set found at the rupestrian settlement of Rivolta, in the ravine of Ginosa (Taranto). In 2004 an archaeological research campaign in the settlement led to the stratigraphic excavation of a cistern (15th-18th century AD. For the filling action, this work proposes an episode contemporary or subsequent to the 18th century AD). The paper exposes how mechanical tinder flints can be recognized in comparison with prehistoric flints, describing the Techno-Functional aspects in a morphological-technological and traceological sense. In US 6, 11 lithic products have been documented: 9 between Paleolithic supports and cores made from the chert of the Fossa Bradanica, divided into systemic categories Kombewa-Levallois, Levallois, Non-Levallois and bipolar on an anvil, as well as pièces esquillées; 2 tinder flint stones in nodular flint, for which one was also hypothesized to be used for manual rubbing, a hypothesis that in this article is revisited by means of new considerations of an experimental nature. The Techno-Functional approach of the tinder flint stones made it possible to identify them as such, by retracing the processes of realization of the production aims, supported by the functional analysis for the evaluation of actual use.
