About the year 2500 B.C. a prince of Elephantine named Herkhuf made up his mind to penetrate farther towards the mysterious lands of the south. It is forty-four centuries since he set out over the desert, with the wind whistling past his ears and a powerful sun warming his bones and his heart within him; yet the story of his adventures may still be read, the path by which he travelled may still be discerned, and the names of his captains may still be seen on the rocks of the land of Arthet. Herkhuf, having obtained the necessary order from the Pharaoh, set out with his father Ata, “in order,” as he says, “to explore a road to the country of Aam.” The road which he explored and opened up was probably a continuation of the route from Elephantine to Arthet, passing not far back from the river, and descending to the water between Abu Simbel and Wady Hâlfa in the heart of the land of Aam. The expedition was entirely successful, and Herkhuf states that he was “very greatly praised for it.” Emboldened by the fame which his enterprise had brought him, he made a second expedition to Aam, and was gone from Egypt eight months. A third excursion was more adventurous. Herkhuf set out upon the “Oasis-road,” which runs from a point north of Aswân to Kurkur Oasis, and thence branches to Tomâs or Arthet and to the Oasis of Khârgeh which lies westward, and which in those days was inhabited by Libyan tribes. At the Kurkur junction Herkhuf met with an army, under the leadership of the Prince of Aam, which was on its way to chastise these Libyans; but how the wily Egyptian contrived to use it instead as an escort to his own men back to Aam, and how he returned to Egypt through the hostile territory of Sethu, Arthet, and Wawat, with 300 asses laden with the presents of his host, are tales too long to narrate here. One story only may be recorded in this chapter. During a fourth expedition to Aam, Herkhuf had managed to obtain one of the dwarfs or pigmies who inhabited a region of the Land of the Ghosts. He at once informed the king, now the boy Pepy II.; and in reply he received the following letter, which is, perhaps, the earliest example in the world’s history of a private communication:-- “I have noted,” writes the King, “the matter of your letter which you have sent to me, in order that I might know that you have returned in safety from Aam, with the army which was with you.... You say in your letter that you have brought a dancing pigmy of the god of the Land of the Ghosts, like the pigmy which the Treasurer Baurded brought from the Land of Pount [Illustration: The Nile at Aswân.
