Senusret III's Canal

     The trade with Ethiopia and Nubia, the region between the First Cataract and the district now known as the sudd region, was on an entirely different basis. A good deal of trade had taken place in predynastic times by means of market to market trading, and this market to market trading continued during the Old Kingdom and the Middle Kingdom. We know of two great markets, Assuan itself (meaning ‘ Market Place ’) and another at the Second Cataract called Iken. But the bulk of the material as far as it was in large quantities must have been transported by water in the protodynastic times. This fact requires an understanding of navigation in the cataract region. During high water (July to October) the cataracts are navigable by ships of moderate size. At the present time the date harvest of Dongola is carried to Wadi Halfa by sailing boats which make two to four trips a season. The difficulty comes in the other eight months, when the water is low and the cataracts are filled with water swirling among the half-exposed rocks.

     The first hint of the opening of a way through the nearest of the cataracts, that at Assuan, is in Dynasty VI. In his autobiography, Weny, a great official of Mernera, relates that His Majesty sent him to Wawat to dig five canals and to construct seven boats for the transportation of granite to Memphis, three cargo boats and four towing boats (manned by rowers). Wawat lies in the granite and sandstone region between the First and the Second Cataract, and there can be little doubt that the five canals were made in the First Cataract itself to permit the passage of these boats loaded with granite for the king’s pyramid. The operation would have consisted in shifting aside a number of boulders at five different places, probably along the western side, to secure quiet passage around the most dangerous places, no great matter for the experienced stone workers who built the pyramids. But we have no knowledge of the size of the canals or as to how long they continued in use.  Weny states that he accomplished the whole business, including the building of the necessary boats, the making of the canals, and the removal of the stones, in one year.
