own,
that the brightest gleams of knowledge have at any time been sufficient
to drive them out of the world. The time, in which this kind of
credulity was at its height, seems to have been that of the holy war, in
which the Christians imputed all their defeats to enchantment or
diabolical opposition, as they ascribe their success to the assistance
of their military saints; and the learned Dr. Warburton appears to
believe (Supplement to the Introduction to Don Quixote) that the first
accounts of enchantments were brought into this part of the world by
those who returned from their eastern expeditions. But there is always
some distance between the birth and maturity of folly, as of wickedness:
this opinion had long existed, though, perhaps, the application of it
had in no foregoing age been so frequent, nor the reception so general.
Olympiodorus, in Photius's Extracts, tells us of one Libanius, who
practised this kind of military magick, and having promised [Greek:
choris hopliton kata barbaron energein], _to perform great things
against the barbarians without soldiers_, was, at the instances of the
emperess Placidia, put to death, when he was about to have given proofs
of his abilities. The emperess showed some kindness in her anger by
cutting him off at a time so convenient for his reputation.

But a more remarkable proof of the antiquity of this notion may be found
in St. Chrysostom's book de Sacerdotio, which exhibits a scene of
enchantments, not exceeded by any romance of the middle age; he supposes
a spectator, overlooking a field of battle, attended by one that points
out all the various objects of horrour, the engines of destruction, and
the arts of slaughter. [Greek: Deiknuto de eti para tois enantiois kai
petomenous hippous dia tinos manganeias kai hoplitas di aeros
pheromenous, kai pasaen goaeteias dunamin kai hidean.]_Let him then
proceed to show him in the opposite armies horses flying by enchantment,
armed men transported through the air, and every power and form of
magick_. Whether St. Chrysostom believed that such performances were
really to be seen in a day of battle, or only endeavoured to enliven his
description, by adopting the notions of the vulgar, it is equally
certain, that such notions were in his time received, and that,
therefore, they were not imported from the Saracens in a later age; the
wars with the Saracens, however, gave occasion to their propagation, not
only as bigotry naturally discove
