Hanno, the Carthaginian--Herodotus visits Egypt, Lybia, Ethiopia, Phoenicia, Arabia, Babylon, Persia, India, Media, Colchis, the Caspian Sea, Scythia, Thrace, and Greece--Pytheas explores the coasts of Iberia and Gaul, the English Channel, the Isle of Albion, the Orkney Islands, and the land of Thule--Nearchus visits the Asiatic coast, from the Indus to the Persian Gulf--Eudoxus reconnoitres the West Coast of Africa--Caesar conquers Gaul and Great Britain--Strabo travels over the interior of Asia, and Egypt, Greece, and Italy. 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. Hanno left Carthage with a fleet of sixty vessels of fifty oars each, carrying 30,000 persons, and provisions for a long voyage. These emigrants, for so we may call them, were destined to people the new towns that the Carthaginians hoped to found on the west coast of Libya, or as we now call it, Africa. The fleet successfully passed the Pillars of Hercules, the rocks of Gibraltar and Ceuta which command the Strait, and ventured on the Atlantic, taking a southerly course. Two days after passing the Straits, Hanno anchored on the coast, and laid the foundation of the town of Thumiaterion. Then he put to sea again, and doubling the cape of Solois, made fresh discoveries, and advanced to the mouth of a large African river, where he found a tribe of wandering shepherds camping on the banks. He only waited to conclude a treaty of alliance with them, before continuing his voyage southward. He next reached the Island of Cerne, situated in a bay, and measuring five stadia in circumference, or as we should say at the present day, nearly 925 yards. According to Hanno's own account, this island should be placed, with regard to the Pillars of Hercules, at an equal distance to that which separates these Pillars from Carthage.
