The geography of Persia is darkly delineated by the Greeks and Latins; but the most illustrious of her cities appear to be more ancient than the invasion of the Arabs. By the reduction of Hamadan and Ispahan, of Caswin, Tauris, and Rei, they gradually approached the shores of the Caspian Sea: and the orators of Mecca might applaud the success and spirit of the faithful, who had already lost sight of the northern bear, and had almost transcended the bounds of the habitable world. Again, turning towards the West and the Roman empire, they repassed the Tigris over the bridge of Mosul, and, in the captive provinces of Armenia and Mesopotamia, embraced their victorious brethren of the Syrian army. From the palace of Madayn their Eastern progress was not less rapid or extensive. They advanced along the Tigris and the Gulf; penetrated through the passes of the mountains into the valley of Estachar or Persepolis, and profaned the last sanctuary of the Magian empire. The grandson of Chosroes was nearly surprised among the falling columns and mutilated figures; a sad emblem of the past and present fortune of Persia: he fled with accelerated haste over the desert of Kirman, implored the aid of the warlike Segestans, and sought an humble refuge on the verge of the Turkish and Chinese power.

After a noble defence, Harmozan, the prince or satrap of Ahwaz and Susa, was compelled to surrender his person and his state to the discretion of the caliph; and their interview exhibits a portrait of the Arabian manners. In the presence, and by the command, of Omar, the gay Barbarian was despoiled of his silken robes embroidered with gold, and of his tiara bedecked with rubies and emeralds: "Are you now sensible," said the conqueror to his naked captive--"are you now sensible of the judgment of God, and of the different rewards of infidelity and obedience?" "Alas!" replied Harmozan, "I feel them too deeply. In the days of our common ignorance, we fought with the weapons of the flesh, and my nation was superior. God was then neuter: since he has espoused your quarrel, you have subverted our kingdom and
