The Vietnamese discovered a Roman era ship buried in the river mud a couple of years ago. Trade was then, as now, a very lucrative enterprise. I imagine the Romans, Egyptians and Phoenicians were very competitive............
For sure. That’s a lot of sailing for a ship back then. I guess the Romans would have to go through the Straits of Gibraltar south along the African coast around the Cape of good Hope, through the Indian ocean. Plenty of place along the way to stop, I’d assume, not like crossing an ocean, but man, that’s a trek.
