The author traces the city's development across more than two millennia, arranging material as a pageant of periods: the Hellenistic age under the Ptolemies, including Cleopatra and Greco-Egyptian literature and science; the Roman and Christian era with its changing fortunes and episodes such as the murder of Hypatia; a reflective interlude on Pagan and Christian philosophy and religion; the long Arab period; and a modern phase of reconstruction culminating in nineteenth-century reforms and later events. A second, practical guide provides maps, site-by-site directions, and cross-references that link present remains to their historical contexts.
