Step-by-step explanation:
The style of the sculpture originally placed on the outside of the Parthenon is a combination of Doric and Ionic elements. The exterior Doric columns are slender with cone-like capitals, while the entablature appears smaller and less weighty than earlier Doric temples. The building itself was decorated with marble sculptures representing scenes from Athenian cult and mythology, including the east pediment which showed the birth of goddess Athena from the head of her father Zeus.
