It is also latin, happening to mean "concerning" "of" or "about", which in this context seems appropriate. (I'm only mildly a latin type, not an art historian, so I'm not sure this is in fact the intended meaning, but it fits, and given the statues classical (albeit greek) history...)

Edit: As sister posts point out, the french meaning is far more appropriate, but the latin is valid as a root.
