It seems likely that somebody in Pompeii knew what China looked like. Victims of the Pompeii eruption were buried by ash. Before the bodies decayed, the ash hardened. Plaster poured into the cavities creates replicas of the bodies. Still standing after 2,000 years, the Pantheon in Rome is one of the greatest Roman architectural works.

This is a bronze saw blade from about 2000 B.C. from the Minoan civilization on Crete. A Minoan washtub from Crete, made of riveted copper. The tub is crushed because the Minoan civilization collapsed literally, from earthquake and the eruption of Thera in the Aegean. The only surviving complex mechanism from antiquity, the Antikythera Mechanism, now in the Archeological Museum in Athens. This is in the museum at Heraklion, Crete.
