Why is it that ships carrying amphorae sink? I’d never be caught with amphorae on the water.
I say giant 25m Humboldt Squid are attracted the amphorae and tend to drag the merchant ship down to their depth, covering their den, where they leave some amphorae as bait for their future prey. Just sayin...<;^)
Maybe it didn't sink with amphorae. Maybe generations of kids were out amphorae cruisin' and threw each one out at the same spot, so they came to rest on a ship already sunk down there. Now we have a different mystery...
