Carthage dispatched Hanno, at the head of a
fleet of 60 ships, to explore and
colonize the northwestern coast of Africa. He sailed west from Carthage toward the
Iberian Peninsula, passing through the
Strait of Gibraltar and founding or repopulating seven colonies along the coast of (what is now)
Morocco. He then continued at least some distance further south along the continent's Atlantic coast, allegedly encountering various
indigenous peoples along his way, who met the fleet with a range of "welcomes". The
gold trade had been a vital foundation of the Carthaginian empire from the fifth century BC, and the desire to secure the gold route to West Africa may have been the original motivation for the exploration of
sub-Saharan Africa. Other sources have questioned this high number of men, with some suggesting 5,000 to be a more accurate number.
Harden reports a consensus that the expedition reached at least as far as
Senegal. Due to the vagueness of the
Periplus, estimates for the voyage's distance range from under to at least . Some agree he could have reached
Gambia. However, Harden mentions disagreement as to the farthest limit of Hanno's explorations:
Sierra Leone,
Cameroon, or
Gabon. He notes the description of
Mount Cameroon, a
volcano, more closely matches Hanno's description than
Guinea's Mount Kakoulima. Warmington prefers Mount Kakoulima, considering Mount Cameroon too "distant". French historian Raymond Mauny, in his 1955 article "La navigation sur les côtes du Sahara pendant l'antiquité", argued that ancient navigators (Hanno,
Euthymenes,
Scylax, etc.) could not have sailed south along the Atlantic coast much farther than
Cape Bojador, in the territory of
Western Sahara. Carthage, reportedly, knew of and conducted some trade with the peoples of the
Canary Islands; ancient geographers were aware of the archipelago, as well, though nothing further south. Ships with square sails, without a stern
rudder, might navigate south, but the winds and currents throughout the year would complicate or prevent the return trip from Senegal to Morocco.
Oared ships might be able to achieve the return northward, but only with very great difficulties and a large crew. Mauny assumed that Hanno did not get farther than the mouth of the river
Drâa, attributing artifacts found on
Mogador Island to the expedition described in the
Periplus of Pseudo-Scylax (dated mid-
4th century BC) and noting that no evidence of Mediterranean trade further south had yet been found. The author ends by suggesting archaeological investigations of the islands along the coast, such as
Cape Verde, or the île de Herné ('Dragon Island', near
Dakhla, Western Sahara) where ancient adventurers may have been stranded and settled.
Gorillai The end of the
periplus describes an island populated with hairy and savage people. Attempts to capture the men failed. Three of the women were taken, but were so ferocious that they were killed, their skins brought home to Carthage. The skins were kept in the Temple of Juno (
Tanit or
Astarte) on Hanno's return and, according to
Pliny the Elder, survived until the
Roman destruction of Carthage in 146 BC, some 350 years after Hanno's expedition. Hanno's interpreters of an African tribe (Lixites or Nasamonians) called the people
Gorillai (in
Greek, ). == Ancient authors' accounts ==
