Overthrow of an Idol Temple, and Abolition of Licentious Practices, at Aphaca in Phœnicia
The emperor's next care was to kindle, as it were, a brilliant torch, by the light of which he directed his imperial gaze around, to see if any hidden vestiges of error might still exist. And as the keen-sighted eagle in its heavenward flight is able to descry from its lofty height the most distant objects on the earth, so did he, while residing in the imperial palace of his own fair city, discover as from a watchtower a hidden and fatal snare of souls in the province of Phœnicia.
This was a grove and temple, not situated in the midst of any city, nor in any public place, as for splendor of effect is generally the case, but apart from the beaten and frequented road, at Aphaca, on part of the summit of Mount Lebanon, and dedicated to the foul demon known by the name of Venus. It was a school of wickedness for all the votaries of impurity, and such as destroyed their bodies with effeminacy. Here men undeserving of the name forgot the dignity of their sex, and propitiated the demon by their effeminate conduct; here too unlawful commerce of women and adulterous intercourse, with other horrible and infamous practices, were perpetrated in this temple as in a place beyond the scope and restraint of law.
Meantime these evils remained unchecked by the presence of any observer, since no one of fair character ventured to visit such scenes. These proceedings, however, could not escape the vigilance of our august emperor, who, having himself inspected them with characteristic forethought, and judging that such a temple was unfit for the light of heaven, gave orders that the building with its offerings should be utterly destroyed. Accordingly, in obedience to the imperial command, these engines of an impure superstition were immediately abolished, and the hand of military force was made instrumental in purging the place.
And now those who had heretofore lived without restraint learned self-control through the emperor's threat of punishment, as likewise those superstitious Gentiles wise in their own conceit, who now obtained experimental proof of their own folly.
