British Museum, London.

This red-figured nestoris (wine jar) was made in Lucania in about 390- 380 BC. 

The Greek myth goes that Aktaion had stumbled across Artemis bathing, and spied on her. However, Artemis caught him watching, so she transformed him into a stag and set his own hounds upon him to rip him to pieces. This brutal scene is what is depicted on the vase.
