That’s very true. By Roman times, the Greeks had been making bronze statues for foreign markets, including the Etruscans, for a while, but they weren’t the only ones making bronzes. If memory serves, there’s at least one surviving Roman marble copy of a Greek bronze original, and one of the Pompeiian frescoes depicts a mythological scene, and one of the characters appears to be a painting made from a bronze statue for its original. :’)
I knew that greek statues were a profitable export item in roman times. The great statue of Poseidon is only the most famous example of the classic statues recovered from the sea floor either from a shipwreck or tossed overboard to lighten the load in a storm.
