The journey was continued for another three weeks, and was the cause of constant surprises to the captives. The extraordinary fertility of the land especially struck them. Cultivation among the Rebu was of a very primitive description, and the abundance and variety of the crops that everywhere met their eye seemed to them absolutely marvelous. Irrigation was not wholly unknown to the Rebu, and was carried on to a considerable extent in Persia; but the enormous works for the purpose in Egypt, the massive embankments of the river, the network of canals and ditches, the order and method everywhere apparent, filled them with surprise and admiration. Many of the cities and temples greatly surpassed in magnificence and splendor those they had first met with, and Amuba’s wonder reached its climax when they arrived at Memphis, till lately the capital of Egypt. The wealth and contents of the city astonished the captives, but most of all were they surprised when they saw the enormous bulk of the pyramids rising a few miles distant from the town, and learned that these were some of the tombs of the kings. The country had now altered in character. On the left a range of steep hills approached the river, and as the march proceeded similar though not so lofty hills were seen on the right. At last, after another fortnight’s traveling, a shout of joy from the army proclaimed that Thebes, the capital of Egypt, the goal of the long and weary march was in view. Thebes stood on both sides of the Nile. On the eastern bank the largest portion of the population was gathered, but this part of the city was inhabited principally by the poorer class. There was, too, a large population on the Libyan side of the Nile, the houses being densely packed near the bank of the river. Behind these were numbers of temples and palaces, while the tombs of the kings and queens were excavated in a valley further back, whose precipitous sides were honeycombed with the rock sepulchers of the wealthy. As the dwelling-houses were all low, the vast piles of the temples, palaces, and public buildings rose above them, and presented a most striking appearance to those approaching the city, which lay in a great natural amphitheater, the hills on both sides narrowing toward the river both above and below it. The march of the royal army from Memphis had been on the western bank of the river, and it was the great Libyan suburb with its palaces and temples that they were approaching. As they neared the city an enormous multitude poured out to welcome the king and the returning army. Shouts of enthusiasm were raised, the sound of trumpets and other musical instruments filled the air, religious processions from the great temples moved with steady course through the dense crowd, which separated at once to allow of the passage of the figures of the gods, and of the priests and attendants bearing their emblems.
