That very night Gawhar laid the foundations of a new city, or rather fortified palace, destined for the reception of his sovereign. He was encamped on the sandy waste which stretched northeast of Fustat on the road to Heliopolis, and there, at a distance of about a mile from the river, he marked out the boundaries of the new capital. There were no buildings, save the old "Convent of the Bones," nor any cultivation except the beautiful park called "Kafur's Garden," to obstruct his plans. A square, somewhat less than a mile each way, was pegged out with poles, and the Maghrabi astrologers, in whom Moizz reposed extravagant faith, consulted together to determine the auspicious moment for the opening ceremony. Bells were hung on ropes from pole to pole, and at the signal of the sages their ringing was to announce the precise moment when the laborers were to turn the first sod. The calculations of the astrologers were, however, anticipated by a raven, who perched on one of the ropes and set the bells jingling, upon which every mattock was struck into the earth, and the trenches were opened. It was an unlucky hour; the planet Mars (El-Kahir) was in the ascendant; but it could not be undone, and the place was accordingly named after the hostile planet, El-Kahira, "the Martial" or "Triumphant," in the hope that the sinister omen might be turned to a triumphant issue. Cairo, as Kahira has come to be called, may fairly be said to have outlived all astrological prejudices. The name of the Abbasside caliph was at once expunged from the Friday prayers at the old mosque of Amr at Fustat; the black Abbasside robes were proscribed, and the preacher, in pure white, recited the Khutba for the imam Moizz, emir el-muminin, and invoked blessings on his ancestors Ali and Fatima and all their holy family. The call to prayer from the minarets was adapted to Shiah taste. The joyful news was sent to the Fatimite Caliph on swift dromedaries, together with the heads of the slain. Coins were struck with the special formulas of the Fatimite creed--"Ali is the noblest of [God's] delegates, the wazir of the best of apostles"; "the Imam Maadd calls men to profess the unity of the Eternal"--in addition to the usual dogmas of the Mahometan faith. For two centuries the mosques and the mint proclaimed the shibboleth of the Shiahs.
