British Museum: Parthenon
The east pediment of the Parthenon. Wikipedia: "The East pediment narrates the birth of Athena from the head of her father, Zeus. According to Greek mythology Zeus gave birth to Athena after a terrible headache prompted him to summon Hephaestus' (the god of fire and the forge) assistance. To alleviate the pain he ordered Hephaestus to strike him with his forging hammer, and when he did, Zeus's head split open and out popped the goddess Athena in full armour. The sculptural arrangement depicts the moment of Athena's birth."
Unfortunately, the center pieces of the pediment were destroyed.

The Parthenon is part of the Acropolis in Athens, Greece. It was built about 438-32 BC. The sculptures and friezes of the Parthenon are one of the most important collections of the British Museum.
The British Museum issued a statement on the Parthenon sculptures in which it defends its choice not to give back the remains to Greece.
