It was while the Hyksos kings were reigning that Abraham visited the Delta. Their court was held at Zoan, now Sân, close to the Asiatic frontier, and on the frontier itself stood their fortress of Avaris, which served at once to bar the way from Asia and to overawe the conquered Egyptians. The Pharaoh of Joseph was probably Apophis III. If so, the Hebrew vizier would have witnessed the outbreak of the war of independence towards the close of the long reign of the Hyksos king. It may be that the policy which transferred the soil of Egypt from the people to the king and the priests gave its first impulse to the movement. The Eighteenth dynasty founded an Egyptian empire. Its kings carried the war into Asia, and planted the boundaries of Egyptian dominion on the banks of the Euphrates. Thothmes III. (B.C. 1503-1449) made Canaan an Egyptian province, dividing it into districts, each under a governor or a vassal prince, who was visited from time to time by a royal commissioner. Carriage roads were constructed, with posting inns at intervals along them where food and lodging could be procured. The country east of the Jordan equally obeyed Egyptian rule. The plateau of Bashan was governed by a single prefect; Ammon and Moab were tributary; Edom alone retained its independence, thanks to its barren mountains, and inaccessible ravines. Thebes, the capital of the dynasty, was adorned with splendid buildings, and all the wealth and luxury of Asia was poured into it. Thothmes established zoological and botanical gardens, where the strange plants, birds, and animals he had collected in his campaigns could be preserved. His immediate predecessor, Queen Hatshepsu, had already revived the exploring expeditions of earlier centuries. An exploring fleet had been sent by her to Punt, the land of frankincense, and it returned home with rarities of all kinds, including apes and giraffes. The history of the expedition and the treasures it brought back were depicted on the walls of the temple built by the queen at Dêr el-Bâhari, after the design of the architect Sen-Mut. The authority of Egypt was not extended to the Euphrates only. Cyprus sent tribute to the Pharaoh, the coasts of Asia Minor, perhaps also of Greece, were harried, and the Sudan was conquered as far south as Berber, if not Khartûm. Under Amen-hotep III., the grandson of Thothmes III., the empire underwent still farther extension. Egyptian temples were erected on the banks of the Upper Nile, and Napata, the future capital of Ethiopia, was built at Gebel Barkal, beyond Dongola.
