The first traveller of whom we have any account in history, is Hanno, who was sent by the Carthaginian senate to colonize some parts of the Western coast of Africa. The account of this expedition was written in the Carthaginian language and afterwards translated into Greek. It is known to us now by the name of the "Periplus of Hanno." At what period this explorer lived, historians are not agreed, but the most probable account assigns the date B.C. 505 to his exploration of the African coast.
