With the single exception of the remains of a mosque enriched with traceries and Arabic legends in a style worthy of the best traditions of Saracenic art, there remains no vestige in Van of any period of prosperity and splendour subsequent to the era of the pre-Armenian kings. It is true that the whole region is subject to seismic influences, and that many of the monuments of later ages may have succumbed through this cause. There exists a tradition that the isolation of the rock of Van itself is due to an earthquake in very ancient times, resulting in its severance from the heights adjacent on the east. Several visitations of considerable severity have probably occurred during the historical period; thus we learn that in the year 1648 of the Christian era one-half of the wall of the fortified city, as well as churches, mosques and private houses, were shattered by successive shocks and fell to the ground. [91] But it is at least doubtful whether posterity has been deprived of many treasures by this agency or by the scourge of such a destroyer as Timur. Van must have occupied a subordinate position among the capitals of the Achæmenian empire; and her ancient temples, together with the structures of her former magnificence, appear to have been demolished at a very early date. A restoration is ascribed to an Armenian king of the Haykian dynasty, who is said to have lived a little prior to the Asiatic conquests of Alexander the Great. But the very fact that this monarch is named Van, and is related to have rechristened the city of Semiramis after himself, invests the story with a fabulous character. [92] Greater credit may be attached to the statement of Moses of Khorene that the place was rebuilt by the first ruler of the Armenian line of the Arsakid or Parthian kings. [93] A colony of Jews, with the high priest of their nation, were settled in Van by one of his successors, the contemporary of King Mithridates of Pontus and his ally against the Roman Power. [94] These Jewish captives appear to have prospered in their new seats; and about the middle of the fourth century of our era they are said to have numbered 18,000 families, who were again transported into captivity, this time into Persia, by the ruler of the new empire which had arisen in Asia, the Sasanian king Shapur. [95] Neither Arsakids nor Sasanians appear to have laid much store by the city; and, indeed, the centres of political gravity in the Asiatic world had undergone a marked change since Assyrian times. The tableland of Persia had become incorporated into the imperial systems of Asia, giving ready access into the Armenian highlands. Europe had already appeared upon the changing scene of Oriental despotisms, and the real struggle was between the East and the West. When the Mohammedan empire of the caliphs had supplanted that of the Sasanian fire-worshippers, Persia and Armenia formed parts of the new structure. With the decay
