American textbooks use the term, British Museum. Like for example, the caption under a picture of a Greek statue might say, Statue of Nike the Goddess of Victory from the British Museum.
The term, British Museum, must mean something different in Britain or the United States, like for example the expression, knock you up.
I wonder about it because I went to school with kids whose parents lived in or near London. Before London, they came from Kenya or Pakistan, mostly.
If I ask them if they have been to the British Museum, they say, "Which one? Britain has lots of museums."
europe probably has more museums in in different cities more than usa, because or probably there is more history involve that we have in the states.
greece, italy, and france has rich backaround of history that express in arts to tell their history.
in the states, like st. louis, we have " st. louis art museum " that represent arts that come all over the world and art states and other things show the history of st, louis and missouri.
across the ocean, it seem like museums " museum of " or " place of " represent that should be more respect than a simple landmark on a state map.
said " state of " to represent an art piece is out of respect that it should get. that why they do it.
