Inhabited by a rude description of people

Various accounts by and about Hanno the Navigator. Hanno lived around the fifth century BC.

From the periplus of Hanno describing the terminus of their voyage along the coast of West Africa.

In its inmost recess was an island similar to that formerly described, which contained in like manner a lake with another island, inhabited by a rude description of people. The females were much more numerous than the males, and had rough skins: our interpreters called them Gorillae. We pursued but could take none of the males; they all escaped to the top of precipices, which they mounted with ease, and threw down stones; we took three of the females, but they made such violent struggles, biting and tearing their captors, that we killed them, and stripped off the skins, which we carried to Carthage: being out of provisions we could go no further.

An unknown world way back in the days before National Geographic.

Wikipedia notes:

When the American physician and missionary Thomas Staughton Savage and naturalist Jeffries Wyman first described the gorillas in the 19th century, the apes were named Troglodytes gorilla after the description in Hanno.

Herodotus, that collector of tales, relates that:

The Carthaginians tell us that they trade with a race of men who live in a part of Libya beyond the Pillars of Herakles. On reaching this country, they unload their goods, arrange them tidily along the beach, and then, returning to their boats, raise a smoke. Seeing the smoke, the natives come down to the beach, place on the ground a certain quantity of gold in exchange for the goods, and go off again to a distance. The Carthaginians then come ashore and take a look at the gold; and if they think it presents a fair price for their wares, they collect it and go away; if, on the other hand, it seems too little, they go back aboard and wait, and the natives come and add to the gold until they are satisfied. There is perfect honesty on both sides; the Carthaginians never touch the gold until it equals in value what they have offered for sale, and the natives never touch the goods until the gold has been taken away.
