To the god held in chief honour at the city of Thebes he presented a ship of cedar wood, 280 cubits in length, of which the visible part was overlaid on the inside with silver and on the outside with gold, and in his honour he also erected two obelisks of hard stone, 120 cubits high, on which he caused to be inscribed the greatness of his power, the number of the subjugated nations, and the amount of his income. When he had reigned thirty-three years his eyesight began to fail, and he voluntarily put an end to his own life. Many generations after, when Darius wished to set up his own image in front of Sesosis, the high priest forbade him in the assembly of priests, and explained that Darius had not surpassed the deeds of Sesosis. So far from being enraged, Darius was pleased at his freedom, and said that he would henceforth make it his object, should an equal length of life be given him, to fall below Sesosis in no respect.[205] Strabo says: Sesostris appears first of all to have conquered the land of the Ethiopians and Troglodytes; on the coast of the Arabian Gulf, between the harbour of the Protectress and the Elephant-hunt, there stood on a hill a temple built by Sesostris in honour of Isis. He succeeded in reaching the land of cinnamon, where pillars and inscriptions are shown as monuments of his campaign. Then he crossed over to Arabia, and it is said that in the narrow part of Ethiopia towards Arabia, on the promontory of Dirê, there was a pillar giving an account of his crossing. From Arabia he went on to invade the whole of Asia, and even forced his way into Europe. In many places ramparts and temples of the Egyptian style are shown as the work of Sesostris. In Egypt he undertook the construction of a canal from the Nile into the Arabian Gulf and the Red Sea.[206] When Germanicus, the son of Drusus, travelled in Egypt, he saw large remains of ancient Thebes. On the mighty walls, so Tacitus continues, the Egyptian inscriptions still remained, telling of their former magnificence. One of the older priests was bidden to translate the Egyptian inscriptions, and he informed them that once there had been 700,000 men of military age in the kingdom, and with this army Ramses had subjugated Libya and Ethiopia, the Medes, Persians, Bactrians, and Scythians, and in addition to these had ruled over the lands from the Bithynian to the Lycian Seas, which are inhabited by the Syrians, the Armenians, and their neighbours, the Cappadocians. The amount of tribute also imposed upon the nations was read, the weight of silver and gold, the number of weapons and horses, the presents of ivory and frankincense for the temples, and how much each nation had to contribute in corn and goods--an amount no less than that which is now imposed by the power of the Parthians or the Romans.[207]
