A caryatid (Greek: Καρυάτις, plural: Καρυάτιδες) is a sculpted female figure serving as an architectural support taking the place of a column or a pillar supporting an entablature on her head. The Greek term karyatides literally means "maidens of Karyae", an ancient town of Peloponnese. Karyai had a famous temple dedicated to the goddess Artemis in her aspect of Artemis Karyatis: "As Karyatis she rejoiced in the dances of the nut-tree village of Karyai, those Karyatides, who in their ecstatic round-dance carried on their heads baskets of live reeds, as if they were dancing plants"

The Parthenon, (ancient Greek: Παρθενών) is a temple built for the Greek goddess Athena,the protectress of Athens, in the 5th century BC on the athenian Acropolis. It is the most important surviving building of Classical Greece, generally considered to be the culmination of the development of the Doric order. Its decorative sculptures are considered one of the high points of Greek art. The Parthenon is regarded as an enduring symbol of ancient Greece and of Athenian democracy, and is one of the world's greatest cultural monuments. The Greek Ministry of Culture is currently carrying out a program of restoration and reconstruction.

The Parthenon replaced an older temple of Athena, called the Pre-Parthenon or Older Parthenon, that was destroyed in the Persian invasion of 480 BC. Like most Greek temples, the Parthenon was used as a treasury, and for a time served as the treasury of the Delian League, which later became the Athenian Empire. In the 6th century AD, the Parthenon was converted into a Christian church dedicated to the Virgin. After the Ottoman conquest, it was converted into a mosque in the early 1460s, and it even had a minaret. On September 28, 1687, an Ottoman ammunition dump inside the building was ignited by Venetian bombardment. The resulting explosion severely damaged the Parthenon and its sculptures. In 1806, Thomas Bruce, 7th Earl of Elgin removed some of the surviving sculptures, with Ottoman permission. These sculptures, now known as the Elgin or Parthenon Marbles, were sold in 1816 to the British Museum in London, where they are now displayed. The Greek government is committed to the return of the sculptures to Greece, so far with no success.
