It is impossible to fix the year in which Phoenicia became independent of Assyria. The last trace of Assyrian interference, in the way of compulsion, with any of the towns belongs to B.C. 645, when she severely punished Hosah and Accho. The latest sign of her continued domination is found in B.C. 636, when the Assyrian governor of a Phoenician town, Zimirra, appears in the list of Eponyms.[14180] It must have been very soon after this that the empire became involved in those troubles and difficulties which led on to its dissolution. According to Herodotus,[14181] Cyaxares, king of Media, laid siege to Nineveh in B.C. 633, or very soon afterwards. His attack did not at once succeed; but it was almost immediately followed by the irruption into South-western Asia of Scythic hordes from beyond the Caucasus, which overran country after country, destroying and ravaging at their pleasure.[14182] The reality of this invasion is now generally admitted. “It was the earliest recorded,” says a modern historian, “of those movements of the northern populations, hid behind the long mountain barrier, which, under the name of Himalaya, Caucasus, Taurus, Hæmus, and the Alps, has been reared by nature between the civilised and uncivilised races of the old world. Suddenly, above this boundary, appeared those strange, uncouth, fur-clad forms, hardly to be distinguished from their horses and their waggons, fierce as their own wolves or bears, sweeping towards the southern regions, which seemed to them their natural prey. The successive invasions of Parthians, Turks, Mongols in Asia, of Gauls, Goths, Vandals, Huns in Europe, have, it is well said, ‘illustrated the law, and made us familiar with its operations. But there was a time in history before it had come into force, and when its very existence must have been unsuspected. Even since it began to operate, it has so often undergone prolonged suspension that the wisest may be excused if they cease to bear it in mind, and are as much startled when a fresh illustration of it occurs, as if the like had never happened before.’[14183] No wonder that now, when the veil was for the first time rent asunder, all the ancient monarchies of the South--Assyria, Babylon, Media, Egypt, even Greece and Asia Minor--stood aghast at the spectacle of these savage hordes rushing down on the seats of luxury and power.”[14184] Assyria seems to have suffered from the attack almost as much as any other country. The hordes probably swarmed down from Media through the Zagros passes into the most fruitful portion of the empire--the flat country between the mountains and the Tigris. Many of the old cities, rich with the accumulated stores of ages, were besieged, and perhaps taken, and their palaces wantonly burnt by the barbarous invaders. The tide then swept on. Wandering from district to district, plundering everywhere, settling nowhere, the clouds of horse passed over Mesopotamia, the force of the invasion becoming weaker as it spread
