15. Superior to all the rest is that which is the nearest to us, Assyria, both in renown, and extent, and its varied riches and fertility. It was formerly divided among several peoples and tribes, but is now known under one common name as Assyria. It is in that country that amid its abundance of fruits and ordinary crops, there is a lake named Sosingites, near which bitumen is found. In this lake the Tigris is for a while absorbed, flowing beneath its bed, till, at a great distance, it emerges again.
16. Here also is produced naphtha, an article of a pitchy and glutinous character, resembling bitumen: on which if ever so small a bird perches, it finds its flight impeded and speedily dies. It is a species of liquid, and when once it has taken fire, human ingenuity can find no means of extinguishing it except that of heaping dust on it.
17. In the same district is seen an opening in the earth from which a deadly vapour arises, which by its foul odour destroys any animal which comes near it. The evil arises from a deep well, and if that odour spread beyond its wide mouth before it rose higher, it would make all the country around uninhabitable by its fetid effect.
18. There used, as some affirm, to be a similar chasm near Hierapolis in Phrygia; from which a noxious vapour rose in like manner with a fetid smell which never ceased, and destroyed everything within the reach of its influence, except eunuchs; to what this was owing we leave natural philosophers to determine.
19. Also near the temple of the Asbamæan Jupiter, in Cappadocia (in which district that eminent philosopher Apollonius is said to have been born near the town of Tyana), a spring rises from a marsh, which, however swollen with its rising floods, never overflows its banks.
20. Within this circuit is Adiabene, which was formerly called Assyria, but by long custom has received its present name from the circumstance, that being placed between the two navigable rivers the Ona and the Tigris, it can never be approached by fording; for in Greek we use διαβαίνειν for to "cross:" this was the belief of the ancients.
21. But we say that in this country there are two rivers which never fail, which we ourselves have crossed, the Diabas, and the Adiabas: both having bridges of boats over them; and that Adiabene has received its name from this last, as Homer tells us Egypt received its name from its great river, and India also, and Commagena which was formerly called Euphratensis, as did the country now called Spain, which was formerly called Iberia from the Iberus.[142] And the great Spanish province of Bœtica from the river Bœtis.[143]
22. In this district of Adiabene is the city of Nineveh, named after Ninus, a most mighty sovereign of former times, and the husband of Semiramis, who was formerly queen of Persia, and also the cities of Ecbatana, Arbela, and Gaugamela, where Alexander, after several other battles, gave the crowning defeat to Darius.
23. In Assyria there are many cities, among which one of the most eminent is Apamia, surnamed Mesene, and Teredon, and Apollonia, and Vologesia, and many others of equal importance. But the most splendid and celebrated are these three, Babylon, the walls of which Semiramis cemented with pitch; for its citadel indeed was founded by that most eminent monarch Belus. And Ctesiphon which Vardanes built long ago, and which subsequently King Pacorus enlarged by an immigration of many citizens, fortifying it also with walls, and giving it a name, made it the most splendid place in Persia—next to it Seleucia, the splendid work of Seleucus Nicator.
24. This, however, as we have already related, was stormed by the generals of Verus Cæsar, who carried the image of the Cumæan Apollo to Rome, and placed it in the temple of the Palatine Apollo, where it was formally dedicated to that god by his priests. But it is said that after this statue was carried off, and the city was burnt, the soldiers, searching the temple, found a narrow hole, and when this was opened in the hope of finding something of value in it, from some deep gulf which the secret science of the Chaldæans had closed up, issued a pestilence, loaded with the force of incurable disease, which in the time of Verus and Marcus Antoninus polluted the whole world from the borders of Persia to the Rhine and Gaul with contagion and death.
