...and the library at Alexandria. I read somewhere (only seen it once and can't find again) that said that, Plutarch, on a tour of the ruins of Carthage, claims to have seen charts/graphs(?) that recorded trade with nations across the Atlantic.
One of the tragedies of history was the sacking of the library. Imagine what what was lost.
He also claimed to have discovered some lost manuscripts of Plutarch, one of which tells the story of the mysterious travel notes found at Carthage. Frankly, I don't believe it.
