Once, Baiae was a resort city on the Italian coast for the wealthy patricians of Rome. Then, volcanic activity caused the city to vanish beneath the waves, as the coastline moved inland.
Divers have now located the town, and discovered that much of the artwork — including statues, tile designs, and mosaics — has been preserved beneath the water. Pretty cool! It would be a great place to go for a dive — if my ear drums had not been blown out by prior, ill-fated scuba activity.
Who knows? Maybe there is something to that Atlantis myth.
