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.
They could have portaged the ship across the place where the Suez canal is now. It was not an unknown process.............
