Alexandria between Antiquity and Islam: Commerce and Concepts in First Millennium Afro-Eurasia

Abstract Late antique Alexandria is much better known than the early Islamic city. To be fully appreciated, the transition must be contextualized against the full range of Afro-Eurasiatic commercial and intellectual life. The Alexandrian schools ‘harmonized’ Hippocrates and Galen, Plato and Aristotle. They also catalyzed Christian theology especially during the controversies before and after the Council of Chalcedon (451) that tore the Church apart and set the stage for the emergence of Islam. Alexandrian cultural dissemination down to the seventh century is here studied especially through evidence for the city’s libraries and book trade, together with the impact of its educational curriculum from Iran to Canterbury. After the Arab conquest, Alexandria turned into a frontier city and lost its economic and political role. But it became a city of the mind whose conceptual legacy fertilized not only Greek scholarship at Constantinople, but also Arabic science and philosophy thanks to the eighth- to ninth-century Baghdadi translation movement. Alexandria emanated occult energies too, thanks to the Pharos as variously misunderstood by Arabic writers, or the relics of its Christian saints, not least the Evangelist Mark, surreptitiously translated to Venice in 828-29. Study of the astral sciences too - astronomy but also astrology - was fertilized from Alexandria, as far afield as India and perhaps China as well as Syria, Baghdad and Constantinople. Egypt’s revival by the Fatimids, who founded Cairo in 961, had little impact on Alexandria until about the end of the eleventh century when, for a time, the city attracted Sunni scholars from as far away as Spain or Iran, while commerce benefited from the rise of the Italian merchant republics and the beginning of the Crusades. While the early caliphate had united a vast zone from Afghanistan to the Atlantic, the eleventh century saw a reemergence of late antique distinctions between the Iranian plateau, Syro-Mesopotamia, and the two Mediterranean basins. Alexandria was one of the points where these worlds intersected, though sub-Saharan Africa, to which it formally belonged, remained largely beyond its horizon until the twentieth century.
