Venus or Diana from Mediana

During the archaeological investigation of the villa with peristyle in Mediana in 2011, a marble head, which may have been the head of a goddess, was discovered. Her face and the treatment of her hair show that it may represent a replica of a Hellenistic original. As far as is known, analogies of female marble heads from Mediana show that it probably represented either the goddess Artemis/Diana or Aphrodite/Venus. A hypothesis was made that the head might have been modelled at the end of the 3rd century - 430 A.D. In addition, a hypothesis was made that the base found in 2002, on which was preserved a fragmented head and the tail of a dolphin, and the new found head were parts of the same statue. If this is the case, then the statue can be identified as the type of Capitol Venus, subtype Venus with dolphin.
