On the Western side of the Nile, at a small distance to the east of the Pyramids, at a small distance to the south of the Delta, Memphis, one hundred and fifty furlongs in circumference, displayed the magnificence of ancient kings. Under the reign of the Ptolemies and CÊsars, the seat of government was removed to the sea-coast; the ancient capital was eclipsed by the arts and opulence of Alexandria; the palaces, and at length the temples, were reduced to a desolate and ruinous condition: yet, in the age of Augustus, and even in that of Constantine, Memphis was still numbered among the greatest and most populous of the provincial cities. The banks of the Nile, in this place of the breadth of three thousand feet, were united by two bridges of sixty and of thirty boats, connected in the middle stream by the small island of Rouda, which was covered with gardens and habitations. The eastern extremity of the bridge was terminated by the town of Babylon and the camp of a Roman legion, which protected the passage of the river and the second capital of Egypt. This important fortress, which might fairly be described as a part of Memphis or _Misrah_, was invested by the arms of the lieutenant of Omar: a reÎnforcement of four thousand Saracens soon arrived in his camp; and the military engines, which battered the walls, may be imputed to the art and labor of his Syrian allies. Yet the siege was protracted to seven months; and the rash invaders were encompassed and threatened by the inundation of the Nile. Their last assault was bold and successful: they passed the ditch, which had been fortified with iron spikes, applied their scaling ladders, entered the fortress with the shout of "God is victorious!" and drove the remnant of the Greeks to their boats and the Isle of Rouda. The spot was afterwards recommended to the conqueror by the easy communication with the gulf and the peninsula of Arabia; the remains of Memphis were deserted; the tents of the Arabs were converted into permanent habitations; and the first mosch was blessed by the presence of fourscore companions of Mahomet. A new city arose in their camp, on the eastward bank of the Nile; and the contiguous quarters of Babylon and Fostat are confounded in their present decay by the appellation of old Misrah, or Cairo, of which they form an extensive suburb. But the name of Cairo, the town of victory, more strictly belongs to the modern capital, which was founded in the tenth century by the Fatimite caliphs. It has gradually receded from the river; but the continuity of buildings may be traced by an attentive eye from the monuments of Sesostris to those of Saladin.
