11. Susis is so fertile in grain, that barley and wheat produce, generally, one hundred, and sometimes two hundred fold. Hence the furrows are not ploughed close together, for the roots when crowded impede the sprouting of the plant. The vine did not grow there before the Macedonians planted it, both there and at Babylon. They do not dig trenches, but thrust down into the ground iron-headed stakes, which when drawn out are immediately replaced by the plants. Such is the character of the inland parts. The sea-coast is marshy and without harbours; hence Nearchus says, that he met with no native guides, when coasting with his fleet from India to Babylonia, for nowhere could his vessels put in, nor was he able to procure persons who could direct him by their knowledge and experience. 12. The part of Babylonia formerly called Sitacene, and afterwards Apolloniatis,[459] is situated near Susis. Above both, on the north and towards the east, are the Elymæi[460] and the Parætaceni, predatory people relying for security on their situation in a rugged and mountainous country. The Parætaceni lie more immediately above the Apolloniatæ, and therefore annoy them the more. The Elymæi are at war with this people and with the Susians, and the Uxii with the Elymæi, but not so constantly at present as might be expected, on account of the power of the Parthians, to whom all the inhabitants [CAS. 732] of those regions are under subjection. When therefore the Parthians are quiet, all are tranquil, and their subject nations. But when, as frequently happens, there is an insurrection, which has occurred even in our own times, the event is not the same to all, but different to different people. For the disturbance has benefited some, but disappointed the expectation of others. Such is the nature of the countries of Persis and Susiana. 13. The manners and customs of the Persians are the same as those of the Susians and the Medes, and many other people; and they have been described by several writers, yet I must mention what is suitable to my purpose. The Persians do not erect statues nor altars, but, considering the heaven as Jupiter, sacrifice on a high place.[461] They worship the sun also, whom they call Mithras, the moon, Venus, fire, earth, winds, and water. They sacrifice, having offered up prayers, in a place free from impurities, and present the victim crowned.[462] After the Magus, who directs the sacrifice, has divided the flesh, each goes away with his share, without setting apart any portion to the gods; for the god, they say, requires the soul of the victim, and nothing more. Nevertheless, according to some writers, they lay a small piece of the caul upon the fire.
