These voyages, if performed in the manner narrated, may justly be reckoned the greatest efforts of navigation in the ancient world; and if we attend to the imperfect state of the art at that time, it is difficult to determine whether we should most admire the courage and sagacity with which the design was formed, or the conduct and good fortune with which it was executed. But, unfortunately, all the original and authentic accounts of the Phoenician and Carthaginian voyages, whether undertaken by public authority or in prosecution of their private, have perished. Whatever acquaintance with the remote regions of the earth the Carthaginians or Phoenicians may have acquired, was concealed from the rest of mankind with a mercantile jealousy. Every thing relating to the course of their navigation was not only a mystery of trade, but a secret of state. Extraordinary facts are recorded concerning their solicitude to prevent other nations from penetrating into what they wished should remain undivulged (_Strab., Geogr._, lib. iii., p. 265; lib. xviii., p. 1154). Many of their discoveries seem accordingly to have been scarcely known beyond the precincts of their own states. The navigation round Africa, in particular, is recorded by the Greek and Roman writers rather as a strange, amusing tale, which they either did not comprehend or did not believe, than as a real transaction which enlarged their knowledge and influenced their opinion. As neither the progress of the Phoenician and Carthaginian discoveries, nor the extent of their navigation, were communicated to the rest of mankind, all memorials of their extraordinary skill in naval affairs seem, in a great measure, to have perished when the maritime power of the former was annihilated by Alexander's conquest of Tyre, and the empire of the latter was overturned by the Roman arms. The Periplus Hannonis is the only authentic monument of the Carthaginian skill in naval affairs, and one of the most curious fragments transmitted to us by antiquity. Montesquieu and De Bougainville have established its authenticity by arguments that appear to me unanswerable. Hanno sailed from Gades to the island of Cerne in twelve days. This is probably what is known to the moderns by the name of the island of Arguim. His furthest advance was to a promontory, which he named the South Horn, manifestly Cape de Tres Puntas, about five degrees north of the line.--Robertson's _America_, vol. i., p. 9-250. No. XI.
