Stricter rules also were made excluding ordinary civilians from Kahira, from which it appears that the seclusion of the guarded city had been somewhat relaxed. In future no one was to be allowed to ride into it, but must dismount and proceed on foot, and all those who let out asses for hire were to be excluded from its precincts, whilst no one was to be allowed to pass in front of the royal palace even on foot.
We must now turn to consider conditions in Syria, for it is always impossible to understand Egyptian history unless the course of events in Syria is kept in view. At the time of Barjawan’s death Syria was under the governorship of Jaysh, but when he died in 390 it became necessary for al-Hakim to nominate a successor for this important post. He chose Fahl of the B. Tamim, but Fahl died after only a few months. The Khalif then appointed ʿAli b. Fallah of the Katama. In 392 the Hamdanid prince of Aleppo, Saʿid ad-Dawla, and his wife, were poisoned by his father-in-law Luʿluʿ, who desired to obtain the throne for himself. He did not seize the supreme power immediately, but proclaimed Saʿid’s two sons ʿAli and Sharif as joint rulers, retaining the real control in his own hands. This continued for two years, then in 394 he sent them together, with the whole of the harim of the Hamdanids to Cairo, and assumed to himself the office and title of Emir in conjunction with his son Mansur, and these two ruled as Emirs under the protection of the Fatimid Khalif until Luʿluʿ’s death in 399. Then Mansur became sole ruler under the title of Murtada l-Dawla which was conferred on him by al-Hakim, and he had the name of the Fatimid Khalif inserted in the Friday prayer and inscribed on the coinage so that by 399 Aleppo was fully admitted as a part of the Fatimid empire, having been a protected district for the previous five years, before which it had for forty years been included in the Byzantine Empire.
The first evidence of al-Hakim’s strong religious interest appears in his diligence as a builder of mosques, and in the completion or adornment of those already erected.
A mosque near the Bab al-Futuh, the second congregational mosque of Kahira, had been commenced by al-ʿAziz and the Wazir Ibn Killis in 380, and was sufficiently advanced to allow the Friday prayers to be held there in 381. In 394 al-Hakim added the minarets and the decorations so that Maqrizi describes him as reconstructing the building. The work was not completed until 404. At first known as the “New Mosque” or as al-Anwar “the brilliant,” it afterwards generally bore the name of Hakim’s Mosque. Desecrated by the Crusaders, severely injured by an earthquake in 703, it was in a semi-ruinous condition by fire and neglect with its roof falling to pieces when Maqrizi wrote his description of it about A.H. 823 (= A.D. 1420. Cf. Maqrizi ii. 277, sqq.). After even worse decay in later days it was temporarily converted in recent times to a museum of Arabic art, the collection being removed to its present quarters in 1903. The mosque is now abandoned and in ruins. Its general plan follows that of the mosque of Ibn Tulun, a square courtyard surrounded with arcades, the centre open to the sky. A considerable part of the east liwan remains, with a few fragments of the north liwan, of the other two sides only portions of the exterior walls survive. Two towers can be seen standing at the ends of the west wall, but the open-work minarets which crown these towers are additions made some three centuries later and alien to the style prevailing in the time of the Fatimids.
In the year 393 al-Hakim also began to rebuild the mosque in the district of Rashida to the south of Kataiʿ near the Mukattam hills, on a ground where a Christian church had once stood. The mosque had been built of brick; this al-Hakim destroyed and reconstructed on a larger scale and of more imposing appearance. It was known as the mosque of Rashida from its position, the ground being so called after a person of that name who had once been its owner. This mosque was commenced in Rabiʿ I. 393, and the position of the mihrab was carefully adjusted by the astronomer ʿAli b. Yunus. Two years later the Khalif made this mosque a present of carpets, curtains, and lamps.
Besides this building al-Hakim made many gifts to various mosques, especially to those he purchased for the special purposes of the Shiʿite sect, presenting them with copies of the Qurʾan, silver lamps, curtains, Samanide mats, etc.
The earlier Fatimids in North Africa present rather a brutal appearance and, so far as we can see, their one ideal was the establishment of political power. But that was not the original character of the movement which had distinct intellectual tendencies, and to this earlier type al-Moʿizz had reverted. Since the dynasty had been established in Egypt the humane side had been more prominently in evidence, and especially in the encouragement of medicine and natural science. The Khalif al-Moʿizz employed the Jewish physician Musa b. al-Ghazzan and his two sons Ishaq and Ismaʿil: these were not only eminent practitioners but Musa was distinguished as a writer on the pharmacopoeia, and all three were regarded as leading authorities on medicine. Another distinguished physician was the Christian Eutychius or Saʿid b. Batriq, patriarch of the Malkite church of Alexandria who died in 328 (= A.D. 943), the author of a history of which an edition in Arabic and Latin was published at Oxford in 1654.
Al-Hakim himself was anxious to encourage scholarship in accordance with the traditions of the sect of which he was the head. The mosque of al-ʾAzhar had been especially devoted to the learned by his father, and now in Jumada II. 395 he founded an academy on the lines of similar institutions already existing at Baghdad and elsewhere. This new foundation was named the Dar al-Hikma or “house of wisdom.” To it were attached a number of professors, both of the traditional sciences and Qurʾan and canon law, and also of the natural sciences. A library was connected with it and was filled with books transferred from the royal palace near by. All who came to it were supplied with ink, pens, paper, and rests for books.
It seems probable that the intellectual efforts of the Fatimids should be connected with the Ikhwanu s-Safa, “the brotherhood of purity” and with the Assassins. The former began as a kind of masonic society at Basra soon after the capture of Baghdad by the Buwayhids in 334. Undoubtedly it had some connection with the sect established by ʿAbdullah the son of Maymun, but it is not possible to specify accurately what that connection was. It may have been a more cultured off-shoot, just as the Qarmatians were a cruder branch; but the more probable explanation is that it was a descendant of the movement which produced ʿAbdullah, but free from the Shiʿite elements which he inherited from the sect founded by his father Maymun. To a large extent it seems that the “Brotherhood” displayed the true principles adopted by the Ismaʿilians free from the Shiʿite ideas and free from the political opportunism which marked the development of the Fatimids in Africa and Egypt. To the Assassins we shall have occasion to return at a later stage. The “Brethren of purity” were disposed in four grades, the highest of which was composed of those who desired the union of their souls with the world-spirit, so that their final doctrine was a species of pantheism. They were a body of religious and ethical reformers, a purified and gentle society, at the opposite pole to the fierce Qarmatians. On the literary side they are best known as the producers of the fifty-one “Epistles of the Brethren of Purity,” an encyclopaedia of philosophy and science as known in the Arabic speaking world of the fourth century. These “Epistles” were edited and translated by Prof. Dieterici between 1858 and 1879, and show a general scheme of education in grammar, theology, philosophy, and physics, the latter including mineralogy, chemistry, botany, and zoology. It is in no sense an original work, but simply an encyclopaedic compilation of all the material then available.
The whole Fatimid movement took place in an atmosphere saturated with Hellenistic thought, and the revived study of the Greek material was the direct inspiration both of the Ismaʿilian sect as organised by ʿAbdullah and of the “Brethren.” But the influence of these latter was checked by the strong tendency towards reaction in Muslim theology and thought generally which was gathering even in the fourth century in Asiatic Islam. The future of the philosophers lay in the far west: Ibn Sina (d. 428) was the last of the Muslim philosophers in the east, and he was associated with Shiʿite circles, whilst al-Farabi had lived under the shelter of the Shiʿite Hamdanids, and the “Brethren” flourished under the Buwayhids who also were Shiʿites. For the most part the study of Greek philosophy, therefore, progressed under Shiʿite influences.
