"But one man bad the courage to defy this slave. He was a descendant of the house of Ali, which could boast of being the house of the great prophet.
"Mahadi Obeidallah was the name of this grandson of Ali. He was strong and mighty before Allah, and he held in his strong hand the green flag of the prophet, of his ancestor, an heir-loom in his family, as he landed from his ships with his troops, at Alexandria, the great city that lies on the shore of Africa, and belongs to the realm of Egypt.
"Nothing could resist the descendant of the prophet, and Mahadi Obeidallah erected his throne in Alexandria. The conquest of Egypt, begun by him, was finished by his grandson, Moez. He brought a hundred thousand men, commanded by his vizier Jauhar, to Alexandria, and marched with them through the desert toward the great city of Fostal, which Caliph Amrou had built.
"Near this great city, Jauhar founded another with splendid walls and palaces, and he called it El-Kahera--that is, the--Victorious.'
Proudly, victoriously, beside the old city of Fostal, arose the new city of El-Kahera, the wondrous city! Moez sat enthroned there in the midst of his realm, and he founded in El-Kahera, the Victorious, the dynasty of the Fatimite caliphs; for Fatima, the daughter of the prophet Mohammed, had married Ali, who was the head of the house from which Moez and Jauhar descended.
"The new city, El-Kahera arose quickly, and soon became the model for all that was beautiful in the arts and sciences in Egypt. The haughty Bagdad, once so mighty, sank into the dust before her.
"But the Fatimites were neither wiser nor more fortunate than the Abbassites, of whom I told you yesterday, had been. The people could not love them, for the Fatimites ruled tyrannically, and knew nothing of pity and love; and the religion of the prophet, which teaches that we should love and do good to our fellow-men, they practised with their tongues only, but not in reality. They thought it sufficient to be able to call themselves descendants of the great prophet, without imitating him in his good works.
"At last one of them even dared to proclaim himself the prophet. His name was Hakem. To him it did not seem enough to be the descendant of Mohammed, of our great prophet--he wished to be king and prophet himself. He desired to found a new religion, and, because the inhabitants of El-Kahera would not bow down before him in the dust, and abandon their prophet, Mohammed, for his sake, he caused the one half of the beautiful city of El-Kahera, the Victorious, to be laid in ashes, and he allowed his wild hordes to plunder and rob the other half. He rejoiced in this, and imagined Allah would be contented. He said, too, that Allah conversed with him each day, and gave him instructions with his own lips. It was for this purpose that he went daily into the mountains of Mokatan, which rise on the banks of the Nile, near the city; and there he, a second Moses, communed, as he declared, with Allah.
"But one day he did not return from the mountains, and when his janizaries sought him they found him lying dead on the ground, pierced with daggers.
"The Fatimites had ruled over Egypt for two hundred years. Their glory was now at an end, and Allah sent the unbelievers as a scourge to punish those who had dared to set themselves above the prophet, to punish the sons of Hakem who had declared himself to be the prophet.
"The unbelievers, who called themselves Christians, came, therefore, with a cross on their arms, and a cross on their banners, conquered El-Kahera, and levied a tribute of many millions of piasters. But the Caliph Addad, a son of Hakem, called to his assistance Noureddin, the ruler of the land of Alep, who sent him a powerful army, and the army of the Christian dogs was scattered like dust before the winds.
"Yet Addad reaped no blessing from the assistance thus called to his side--the son was to be punished for the misdeeds and tyranny of his father Hakem. A strong and mighty man had come with Noureddin's army; he made himself Addad's vizier, their commander-in-chief, and Addad died of mortification. Saladin the son of Ayoub, assumed his place, and became the ruler of Egypt, and founded the dynasty of the Ayoubites."
