Athena, the Stymphalian Birds and Hercules
Hercules has just wiped out the awful birds and presents to his proctectress Athena the loot of his hunt.
Athena, without helmet, is seated with naked feet on a rock (= her acropolis?), clothed with a peplos and wearing the aegis. 
This scene is without equal in all Greek art.
All but Hercules' trunk and legs are in Paris (Louvre).
