Abstract

In this paper the authors have analyzed a fragmentary amphora found in the Venetian lagoon at Chiese Bruciate, which has analogies with another amphora from the lagoon which was found in the Rigà Canal. By comparing the amphorae on a typological basis it was found that they represent one of the least common shapes among the amphorae produced in the eastern Mediterranean which are known as the Late Roman type. Both of the amphorae discovered in the lagoon seem to have been imported from Asia Minor or the Aegean area of the Mediterranean during the Late Antique or Byzantine era. The amphora from Chiese Bruciate was attributed to the Late Roman 2 group and in particular to the Dyczek 25 type. As has been done in other study cases, along with the typological analysis a geometric shape study - i.e., a morphometric analysis of the amphorae made by comparing the different forms using geometric indexes calculated on the coordinates of the points measured on the outline of the vase - have also been conducted. Two known statistical indices were used: the coefficient r of Bravais Pearson and the similarity ratio k. For the analysis of the analogies between the shape of the amphora from Chiese Bruciate (SB) and the other amphorae open source R software was used.
