This lake was begun by former princes, and enlarged by Queen Amense, in order to receive the surplus waters of the Nile, when the inundations, as sometimes happen, arise and overflow the fields after the corn is up. The lake, however, was not large enough wholly to correct this evil, and King Mœris still further enlarged it, by means of the services of the Hebrews, three hundred thousand of whom, it is said, perished in the work, before it was completed. It is ample enough in breadth and depth to contain the excess of the Nile. One of the wonders of the world, it is only paralleled in grandeur by the pyramids. In the midst of this magnificent inland sea--for such it seems--arise two pyramids, upon the summit of each of which, three hundred and eight feet in the air, stands upon a throne, shaped like a chariot, a statue, one being that of Thoth, the other of Mœris. Upon the former is inscribed-- "The god prospered;" on the other, "Pharaoh builded." Beneath this inscription is written-- "This lake is three hundred and forty miles in circumference, and one hundred and fifty feet in depth. Within its bounds it can contain all the rivers of the earth." This sublime work, my dear father, has upon the east side a canal eighty feet broad, and four leagues in length. At its entrance are seated two colossi, figures of Apis and Mnevis; and along its shores are double rows of trees, bordering a terrace, upon which face palaces, villas, temples, gardens, and squares. At the Nile termination stands a single colossus, representing the god Nilus. He is astride the canal, his feet upon the bases of pyramids, and beneath him are great floodgates, that let in or exclude the waters of the river. On the south of the lake, upon a plain of sand, Mœris erected a vast temple to Serapis, dedicated it with great pomp, and inclosed it by gardens a mile square, the earth of which was carried by Hebrews in baskets, from the excavations of the lake. He commenced a noble avenue of sphinxes, leading from the lake to the temple, and which has been recently completed by Thothmeses IV., who last week invited me to be present at its inauguration. It was a magnificent spectacle, first the procession of priests and soldiers, nobles and citizens, with the king and his court, in a thousand galleys, sailing across the lake; then the landing at the majestic pylon, the march of the procession for a mile between the double row of sphinxes, the mighty temple terminating the vista, and the solemn invocations, libations, and sacrifices before the god.
