The Parthenon Frieze is a high-relief marble sculpture created to adorn the upper part of the Parthenon in Athens, completed around 432 BC. It depicts the Panathenaic procession, a festival held in honor of the goddess Athena. In the early 19th century, Thomas Bruce, the 7th Earl of Elgin, removed about half of the surviving sculptures and transported them to Britain, where they became known as the 'Elgin Marbles.' Today, they are housed in the British Museum. This has led to one of the longest-running cultural property disputes in history, with the Greek government repeatedly demanding their return to Athens to be reunited with the rest of the frieze in the Acropolis Museum. The sculptures are considered masterpieces of the 'High Classical' style, showing incredible anatomical detail and fluid movement in stone. The debate touches on complex issues of museum ethics, colonial history, and the concept of universal cultural heritage.
