It is said that about this time a prophecy was current, which declared that the Roman Empire would be overthrown by a circumcised people. This report may have been spread by the Jews, in order to excite their own ardour and assist their projects of rebellion; but the prophecy was saved from oblivion by the subsequent conquests of the Saracens, which could never have been foreseen by its authors. The conduct of the Jews excited the bigotry, as it may have awakened the fears, of the imperial government, and both Phocas and Heraclius attempted to exterminate the Jewish religion and if possible to put an end to the national existence. Heraclius not only practised every species of cruelty himself to effect this object within the bounds of his own dominions, but he even made the forced conversion or banishment of the Jews a prominent feature in his diplomacy. He consoled himself for the loss of most of the Roman possessions in Spain, by inducing Sisibut to insert an article in the treaty of peace concluded in 614, engaging the Gothic monarch to force baptism on the Jews; and he considered that, even though he failed in persuading the Franks to co-operate with him against the Avars, in the year 620, he had rendered the empire and Christianity some service by inducing Dagobert to join in the project of exterminating the unfortunate Jews. Asia Minor had become the chief seat of the Roman power in the time of Heraclius, and the only portion in which the majority of the population was attached to the imperial government and to the Greek church. Before the reign of Phocas, it had escaped any extensive devastation, so that it still retained much of its ancient wealth and splendour; and the social life of the people was still modelled on the institutions and usages of preceding ages. A considerable internal trade was carried on; and the great roads, being kept in a tolerable state of repair, served as arteries for the circulation of commerce and civilisation. That it had, nevertheless, suffered very severely in the general decline caused by over-taxation, and by reduced commerce, neglected agriculture, and diminished population, is attested by the magnificent ruins of cities which had already fallen to decay, and which never again recovered their ancient prosperity.
