By the treaty just spoken of, Ptolemy, in the thirteenth year after the death of Alexander, was left undisputed master of Egypt. During these years he had not only gained the love of the Egyptians and Alexandrians by his wise and just government, but had won their respect as a general by the skill with which he had kept the war at a distance. He had lost and won battles in Syria, in Asia Minor, in the island of Cyprus, and at sea; but since Perdiccas marched against him, before he had a force to defend himself with, no foreign army had drunk the sacred waters of the Nile. It was under the government of Ptolemy that the wonders of Upper Egypt were first seen by any Greeks who had leisure, a love of knowledge, and enough of literature, to examine carefully and to describe what they saw. Loose and highly coloured accounts of the wealth of Thebes had reached Greece even before the time of Homer, and again through Herodotus and other travellers in the Delta; but nothing was certainly known of it till it was visited by Hecataeus of Abdera, who, among other works, wrote a history of the Hyperborean or northern nations, and also a history, or rather a description of Egypt, part of which we now read in the pages of Dio-dorus Siculus. When he travelled in Upper Egypt, Thebes, though still a populous city, was more thought of by the antiquary than by the statesman. Its wealth, however, was still great; and when, under the just government of Ptolemy, it was no longer necessary for the priests to hide their treasures, it was found that the temples still held the very large sum of three hundred talents of gold, and two thousand three hundred talents of silver, or above five million dollars, which had escaped the plundering hands of the Persian satraps. Many of the Theban tombs, which are sets of rooms tunnelled into the hills on the Libyan side of the Nile, had even then been opened to gratify the curiosity of the learned or the greediness of the conqueror. Forty-seven royal tombs were mentioned in the records of the priests, of which the entrances had been covered up with earth, and hidden in the sloping sides of the hills, in the hope that they might remain undisturbed and unplundered, and might keep safe the embalmed bodies of the kings till they should rise again at the end of the world; and seventeen of these had already been found out and broken open. Hecataeus was told that the other tombs had been before destroyed; and we owe it, perhaps, to this mistake that they remained unopened for more than two thousand years longer, to reward the searches of modern travellers, and to unfold to us the history of their builders.
