and pernicious virtues of
a bigot. [1211] While he started and satisfied the scruples of a blind
conscience, the siege was continued through the winter by the neglect,
rather than by the resolution of the caliph Omar. [13] The winter proved
uncommonly rigorous: above a hundred days the ground was covered with
deep snow, and the natives of the sultry climes of Egypt and Arabia lay
torpid and almost lifeless in their frozen camp. They revived on the
return of spring; a second effort had been made in their favor; and
their distress was relieved by the arrival of two numerous fleets, laden
with corn, and arms, and soldiers; the first from Alexandria, of four
hundred transports and galleys; the second of three hundred and sixty
vessels from the ports of Africa. But the Greek fires were again
kindled; and if the destruction was less complete, it was owing to the
experience which had taught the Moslems to remain at a safe distance, or
to the perfidy of the Egyptian mariners, who deserted with their ships
to the emperor of the Christians. The trade and navigation of the
capital were restored; and the produce of the fisheries supplied the
wants, and even the luxury, of the inhabitants. But the calamities of
famine and disease were soon felt by the troops of Moslemah, and as the
former was miserably assuaged, so the latter was dreadfully propagated,
by the pernicious nutriment which hunger compelled them to extract from
the most unclean or unnatural food. The spirit of conquest, and even of
enthusiasm, was extinct: the Saracens could no longer struggle, beyond
their lines, either single or in small parties, without exposing
themselves to the merciless retaliation of the Thracian peasants.

An army of Bulgarians was attracted from the Danube by the gifts and
promises of Leo; and these savage auxiliaries made some atonement for
the evils which they had inflicted on the empire, by the defeat and
slaughter of twenty-two thousand Asiatics. A report was dexterously
scattered, that the Franks, the unknown nations of the Latin world, were
arming by sea and land in the defence of the Christian cause, and their
formidable aid was expected with far different sensations in the camp
and city. At length, after a siege of thirteen months, [14] the hopeless
Moslemah received from the caliph the welcome permission of retreat.
[1411] The march of the Arabian cavalry over the Hellespont and through
the provinces of Asia, was executed without delay o
