Wow!
Thanks for posting this. Very exciting.
Somewhere around here (probably in the earlier topics about ancient circumnavigation of Africa and whatnot) there’s stuff on Herodotus’ account of the clockwise CN of Africa, which was commissioned by a pharaoh; also, stuff regarding the Periplus of Hanno, which pertains to Carthaginian exploration of the western coast of Africa at least as far south as Mount Cameroon.
