All of the paintings previously posted are still to be found either in situ (i.e. where they were found) or at the local museums. Some other paintings have unfortunately been removed without a note on where they were found - and there's no way to find out now.
This is one such painting, found somewhere in Campania. It's made in the 2nd style between 50 and 30 bc (more on the styles in a few days) and we see a theatrical mask to the right and the attributes of Heracles - we can speculate and wonder if this is meant to depict a play about Hero.
