Stamnoses (large vessels for wine) were often used in rituals of the dying and resurrecting god Dionysus, patron of wine and grapes. From the 5th century BC they were commissioned by rich Etruscans. This vessel was found in one of the Etruscan tombs. The scene depicted on it is from the myth of Agamemnon, the leader of the Trojan campaign of the Greeks, who was killed on his return home by his wife Clytemnestra (the sister of Helen of Troy) and her lover Aegisthus. His son Orestes (kills Aegisthus sitting on the throne with his sword) and his daughter Electra (runs with an axe after Orestes) take revenge for their father. The tragic theme was often performed in Greek theater: Aeschylus staged the Oresteian Trilogy (458 BC) at the feast of Dionysus in Athens; later this theme was paid tribute to by Sophocles and Euripides. The stamnos was painted by the Copenhagen master who skillfully combined the drama of the scene with a delicate interpretation of the heroes' figures and their vestments.
The vessel was used for libations: there is an opening in the bottom.
It is reassembled from fragments with numerous fillings . The back side was restored in the 19th century and partially painted over.
