The Roman emperor soon regained possession of the city; but scarcely was it beginning to recover the shock sustained from the fire-worshippers, when it became the prey of a much more powerful race of fanatics. In 635, the Saracens, under the command of Khaled, the most redoubtable general of Arabia, laid siege to it. The first attack lasted ten days, and the Christians defended themselves with heroic courage. During four months, every day brought its sanguinary conflict; but at length, the unfortunate citizens, being without hope of succour, yielded to the perseverance of the Mussulmans, and by the means of the Patriarch Sophronius, capitulated with the Caliph Omar in person. The following are the conditions of this treaty, which afterwards served as a model to the Mahometans: “In the name of the All-Merciful God, Omar Ebn-Alkhetlab, to the inhabitants of Ælia (the name given to it by its restorer, Ælius Adrianus). They shall be protected; they shall preserve their lives and their property. Their churches shall not be destroyed, but they shall erect no new ones, either in the city or its territories: they alone shall enjoy the use of them. They shall not prevent Mussulmans from entering them, by day or night; the doors of them shall be open to passers-by and to travellers. If any Mussulman, who may be travelling, should pass through their city, he shall be entertained gratis during three days. They shall not teach the Koran to their children, they shall not speak publicly of their own religion, and shall make no efforts to induce others to embrace it. They shall not prevent their kindred from becoming Mussulmans, if they should be so disposed; they shall show respect to Mussulmans, and shall rise up when they wish to be seated. They shall not be clothed like Mussulmans; they shall not wear the same caps, shoes, or turbans. They shall not part their hair as the Mussulmans do; they shall not speak the same language, or be called by the same names. On horseback, they shall use no saddles; they shall carry no sort of arms, and shall not employ the Arabian language in the inscriptions upon their seals. They shall not sell wine; they shall be distinguished by the same description of clothes, wherever they go, and shall always wear girdles. They shall erect no crosses upon their churches, and they shall not exhibit their crosses or their books publicly in the streets of the Mussulmans. They shall not ring their bells, but shall content themselves with tolling them. They shall never take a domestic who has served a Mussulman.” They were obliged to ratify this act of servitude, and to open the gates to the Saracens, who took possession of their conquest.
