     The Parthenon in Athens is a building with a long and complex history.Built nearly 2,500 years ago

as a temple celebrating the Greek goddess Athena, it was for thousands of years the church of the

Virgin Mary of the Athenians, then a mosque (清真寺), and finally a ruin.The building was changed

and the sculptures were much damaged over the centuries.By 1800 only about half of the original

sculptural decoration remained.

     Between 1801 and 1805, Lord Elgin, the British ambassador to the Ottoman Empire, which

controlled Athens, acting with the full knowledge and permission of the Ottoman authorities, removed

about half of the remaining sculptures from the fallen ruins and from the building itself.Lord Elgin loved

Greek history and transported the sculptures back to Britain.The arrival of the sculptures in London

had a huge effect on the European public, greatly increasing interest in ancient Greek culture and

influencing contemporary artistic trends.These sculptures were acquired from Lord Elgin by the British

Museum in 1816 and since then they have all been on display to the public, free of charge.

     Since the early 1980s, however, the Greek government has argued for the permanent removal to

Athens of all the Parthenon sculptures in the British Museum.They have also challenged the British

Museum Board of Trustees' legal title to the sculptures.

     The British Museum, however, insists that it exists to tell the story of cultural achievement throughout

the world, from the dawn of human history over two million years ago until the present day.The museum

considers itself an important resource for the world: the breadth and depth of its collection allows the world public to reexamine cultural identities and explore the complex network of interconnected world cultures.

     It also says that, within the context of this unparalleled collection, the Parthenon sculptures are an

important representation of ancient Athenian civilization.Each year millions of visitors admire the artistry

of the sculptures and gain insights on how ancient Greece influenced-and was influenced by the other

civilizations that it encountered(遭遇)．
