and in the termination of their obligation to contribute towards the maintenance of the Caspian Gates. If there was any real danger of those results following from the Persian occupation of Lazica which both nations anticipated, the sum must be considered to have been one of the best investments ever made by a State. Even if we believe the dangers apprehended to have been visionary, yet it cannot be viewed as an exorbitant price to have paid for a considerable tract of fertile country, a number of strong fortresses, and the redemption of an obligation which could not with honor be disowned. To Chosroes the advantage secured by the treaty was similar to that which Rome had obtained by the peace of A.D. 532. Being no longer under any necessity of employing his forces against the Romans in the north-west, he found himself free to act with greatly increased effect against his enemies in the east and in the south. Already, in the interval between the conclusion of the general truce and of the fifty years’ peace, he had, as it seems, invaded the territories of the Ephthalites, and, with the help of the Great Khan of the Turks, inflicted upon this people, so long one of Persia’s most formidable enemies, a severe defeat. According to Tabari, he actually slew the Ephthalite monarch, ravaged his territory, and pillaged his treasures. About the same time he had also had a war with the Khazars, had overrun their country, wasted it with fire and sword, and massacred thousands of the inhabitants. He now entertained designs against Arabia and perhaps India, countries on which he could not hope to make an impression without earnest and concentrated effort. It was doubtless with the view of extending his influence into these quarters that the Persian monarch evacuated Lazica, and bound his country to maintain peace with Rome for the next half-century.
