e experience, perhaps the secret intelligence,
of Amrou had taught him to suspect the mutability of courts; and he
continued his march till his tents were unquestionably pitched on
Egyptian ground. He there assembled his officers, broke the seal,
perused the epistle, gravely inquired the name and situation of the
place, and declared his ready obedience to the commands of the caliph.
After a siege of thirty days, he took possession of Farmah or Pelusium;
and that key of Egypt, as it has been justly named, unlocked the
entrance of the country as far as the ruins of Heliopolis and the
neighborhood of the modern Cairo.

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 Caesars, 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 reenforcement 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 c
