The limit of Ptolemy's knowledge in the west is Cape Spartel (35° 48′ N); while he does assume that the coast eventually retreats in a "Great Gulf of the Western Ocean", this is not likely based on any knowledge of the Gulf of Guinea. Eric Anderson Walker, The Cambridge history of the British Empire, Volume 7, Part 1, 1963, p. 66. In the east, Ptolemy is aware of the Red Sea (Sinus Arabicus) and the protrusion of the Horn of Africa, describing the gulf south of the Horn of Africa as Sinus Barbaricus.

Alan Lloyd suggests that the Greeks at this time understood that anyone going south far enough and then turning west would have the sun on their right but found it unbelievable that Africa reached so far south. He suggests that "It is extremely unlikely that an Egyptian king would, or could, have acted as Necho is depicted as doing" and that the story might have been triggered by the failure of Sataspes attempt to circumnavigate Africa under Xerxes the Great.
