The Commerce of Egypt. 399 §5. The Commerce of Egypt. When, under the great Theban Pharaohs, Egypt found herself impelled, either by force or by inclination, to emerge from her lone isolation, her vast internal commerce and her industrial development must have had a greater effect over the foreigners with whom she came into contact than her gigantic buildings, or the colossal statues, bas-reliefs, and paintings with which they were adorned. During the Middle Empire she opened her gates to some extent to certain tribes of Semites and Kushites, who dwelt close to her frontier. After her conquest by the Hyksos, and the establishment, some centuries later, of her own supremacy in Syria, she never ceased to hold intercourse with her neighbours. Her foreign relations were, however, peculiar in character. During many centuries it never occurred to the worshipper of Osiris that it was possible to live and die out of the sacred valley of the Nile. Thrown by some accident outside those limits which for him coincided with the frontiers of the habitable world, he would have felt as helpless as a Parisian stranded upon some cannibal island. In later years, after about the seventeenth century b.c. the separation between the Egyptians and the people of Western Asia became less complete. The time arrived when Babylon and Greece were in advance of Eg}^pt ; but even then the Egyptians shrank from changing their ancient habits. Their well-being in the valley watered by their sacred river was too complete, their pride of race was too great, to allow of their mingling readily with those whom they looked upon as barbarians. Still more effectual was their unwillingness, their fear, to confide their mortal bodies to any other soil but that of Egypt. There alone could they count with certainty upon the care and skill which would preserve it from final destruction. Nowhere but in the Western Mowitain could they be sure of receiving the necessary offerings and homage. The gods who watched over the mummy, who guided the soul in its subterranean voyage and shielded it during 'the tests to which it was exposed after death, dwelt in Egypt alone. INIilitar)- expeditions were pushed into Syria, and even as far as the Euphrates, but no Egyptian crossed the Isthmus of Suez without longing for the day of his return.
