(M168) Under his successors, the empire rapidly declined. Though it nominally included the whole of Western Asia, from the Mediterranean to the desert of Iran, and from the Caspian Sea and the mountains of Armenia to the Persian Gulf, it was wanting in unity. It embraced various kingdoms, and cities, and tribes, which simply paid tribute, limited by the power of the king to enforce it. The Assyrian armies, which committed so great devastations, did not occupy the country they chastised, as the Romans and Greeks did. Their conquests were like those of Tamerlane. As the monarchs became effeminated, new powers sprung up, especially Media, which ultimately completed the ruin of Assyria, under Cyaxares. The last of the monarchs was probably the Sardanapalus of the Greeks. (M169) The decline of this great monarchy was so rapid and complete, that even Nineveh, the capital city, was blotted out of existence. No traces of it remained in the time of Herodotus, and it is only from recent excavations that its site is known. Still, it must have been a great city. The eastern wall of it, as it now appears from the excavations, is fifteen thousand nine hundred feet (about three miles); but the city probably included vast suburbs, with fortified towers, so as to have been equal to four hundred and eighty stadias in circumference, or sixty miles—the three days’ journey of Jonah. It is supposed, with the suburbs, to have contained five hundred thousand people. The palaces of the great were large and magnificent; but the dwellings of the people were mean, built of brick dried in the sun. The palaces consisted of a large number of chambers around a central hall, open to the sky, since no pillars are found necessary to support a roof. No traces of windows are found in the walls, which were lined with slabs of coarse marble, with cuneiform inscriptions. The façade of the palaces we know little about, except that the entrances to them were lined by groups of colossal bulls. These are sculptured with considerable spirit, but _art_, in the sense that the Greeks understood it, did not exist. In the ordinary appliances of life the Assyrians were probably on a par with the Egyptians; but they were debased by savage passions and degrading superstitions. They have left nothing for subsequent ages to use. Nothing which has contributed to civilization remains of their existence. They have furnished no _models_ of literature, art, or government. (M170) While Nineveh was rising to greatness, Babylon was under an eclipse, and thus lasted six hundred and fifty years. It was in the year 1273 that this eclipse began. But a great change took place in the era of Narbonassar, B.C. 747, when Babylon threatened to secure its independence, and which subsequently compelled Esar-Haddon, the Assyrian monarch, to assume, in his own person, the government of Babylon, B.C. 680.
