No other expedition in ancient times is known to have proceeded so far south as Sierra Leone. Two other voyages upon this Atlantic coast are mentioned, but without definite details. The one was that of Sataspes (about 470 B. C.), narrated by Herodotus, who merely tells us that a coast was reached where undersized men, clad in palm-leaf garments, fled to the hills at sight of the strange visitors.[355] The other was that of Eudoxus (about 85 B. C.), related by Posidonius, the friend and teacher of Cicero. The story is that this Eudoxus, in a voyage upon the east coast of Africa, having a philological turn of mind, wrote down the words of some of the natives whom he met here and there along the shore. He also picked up a ship's prow in the form of a horse's head, and upon his return to Alexandria some merchants professed to recognize it as belonging to a ship of Cadiz. Eudoxus thereupon concluded that Africa was circumnavigable, and presently sailed through the Mediterranean and out upon the Atlantic. Somewhere upon the coast of Mauritania he found natives who used some words of similar sound to those which he had written down when visiting the eastern coast, whence he concluded that they were people of the same race. At this point he turned back, and the sequel of the story was unknown to Posidonius.[356] [Footnote 355: Herodotus, iv. 43.] [Footnote 356: The story is preserved by Strabo, ii. 3, Sec.Sec. 4, 5, who rejects it with a vehemence for which no adequate reason is assigned.] [Sidenote: Wild exaggerations.] It is worthy of note that both Pliny and Pomponius Mela, quoting Cornelius Nepos as their authority, speak of Eudoxus as having circumnavigated Africa from the Red Sea to Cadiz; and Pliny, moreover, tells us that Hanno sailed around that continent as far as Arabia,[357]--a statement which is clearly false. These examples show how stories grow when carelessly and uncritically repeated, and they strongly tend to confirm the doubt with which one is inclined to regard the tale of Necho's sailors above mentioned. In truth, the island of Gorillas, discovered by Hanno, was doubtless the most southerly point on that coast reached by navigators in ancient times. Of the islands in the western ocean the Carthaginians certainly knew the Canaries (where they have left undoubted inscriptions), probably also the Madeiras, and possibly the Cape Verde group.[358] [Footnote 357: Pliny, _Hist. Nat._, ii. 67; Mela, _De Situ Orbis_, iii. 9.]
