The city of Jerusalem
(1909)
“ Khosrau I. had conceived the ambitious idea of conquering Western Asia; but he was held in check by Justinian, who was allied to the Turks on his north and to the Sabean kings on the south. The grandson (Khosrau II.) took advantage of the weakness of Phocas, and attacked Aleppo and Antioch in 610 A. D., while Heraclius, son of the exarch, was besieging the upstart centurion in Byzantium. For ten years Khosrau II. held Chalcedon, and the Persian forces faced the new Greek emperor at Constantinople. The victorious Sassanian entered Alexandria, and in 614 A. D. the Persians besieged Jerusalem. ”
