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. Æschylus¹ 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.
