The (early) middle Neolithic of the Trieste Karst, known as Vlaška Group or Neolitico dei vasi a coppa, has been analysed, mainly since the 1960s onwards, by different scholars who have given often divergent interpretations. The systematic revisions of the materials from many cave deposits that had remained largely unpublished till the early 1990s have increased the data set, allowing to better define the main components of this facies. Geo-sedimentological and archaeometrical analyses carried out in the same years have contributed to connect the material culture to the presence of shepherds who visited the Karst coming from both close and more or less distant areas.
