Probably right, but it sure is a pretty sailing picture. And the sea worthy qualities of the ships was the issue to this thread.
Well, yeah, I see your point.
By the way, was the account I read some 40 years ago incorrect about how the Phoenicians recorded words had them see the sun reverse sides (rise in the southern side, not the northern part, as indicating going below the equator, and switching on the other side)? Or that they each year went ashore to plant grain for sustainance? It was a questionable source, a Reader's Digest supposed to be factual book, but where are the actual translations located online and how did they survive to present day?
Well, I don't know if that specific annecdote is incorrect or not (the bit about the sun rising on the southern side probably is incorrect), but what is correct is that the expedition of Hanno the Navigator in the 5th century BC reached as far as the Gulf of Guinea. Ptolemy has a surprisingly extensive entry on the coastline of western Africa, and this only makes sense if he incorporated Hanno's travel journal.
