[CAS. 727] Its length, according to Eratosthenes, towards the north and Media,[441] is about 8000, or, including some projecting promontories, 9000 stadia; the remainder (from Media) to the Caspian Gates is not more than 3000 stadia. The breadth in the interior of the country from Susa to Persepolis is 4200 stadia, and thence to the borders of Carmania 1600 stadia more. The tribes inhabiting this country are those called the Pateischoreis, the Achæmenidæ, and Magi; these last affect a sedate mode of life; the Curtii and Mardi are robbers, the rest are husbandmen. 2. Susis also is almost a part of Persis. It lies between Persis and Babylonia, and has a very considerable city, Susa. For the Persians and Cyrus, after the conquest of the Medes, perceiving that their own country was situated towards the extremities, but Susis more towards the interior, nearer also to Babylon and the other nations, there placed the royal seat of the empire. They were pleased with its situation on the confines of Persis, and with the importance of the city; besides the consideration that it had never of itself undertaken any great enterprise, had always been in subjection to other people, and constituted a part of a greater body, except, perhaps, anciently in the heroic times. It is said to have been founded by Tithonus, the father of Memnon. Its compass was 120 stadia. Its shape was oblong. The Acropolis was called Memnonium. The Susians have the name also of Cissii. Æschylus[442] calls the mother of Memnon, Cissia. Memnon is said to be buried near Paltus in Syria, by the river Badas, as Simonides says in his Memnon, a dithyrambic poem among the Deliaca. The wall of the city, the temples and palaces, were constructed in the same manner as those of the Babylonians, of baked brick and asphaltus, as some writers relate. Polycletus however says, that its circumference was 200 stadia, and that it was without walls. 3. They embellished the palace at Susa more than the rest, but they did not hold in less veneration and honour the palaces at Persepolis and Pasargadæ.[443] For in these stronger and hereditary places were the treasure-house, the riches, and tombs of the Persians. There was another palace at Gabæ, in the upper parts of Persia, and another on the sea-coast, near a place called Taoce.[444] This was the state of things during the empire of the Persians. But afterwards different princes occupied different palaces; some, as was natural, less sumptuous, after the power of Persis had been reduced first by the Macedonians, and secondly still more by the Parthians. For although the Persians have still a kingly government, and a king of their own, yet their power is very much diminished, and they are subject to the king of Parthia.
