Folly of Polytheism
But also the sepulchres of his sons, who are regarded among these the Gentiles as gods, are openly pointed out, one in one place, and another in another: that of Mercury at Hermopolis; that of the Cyprian Venus at Cyprus; that of Mars in Thrace; that of Bacchus at Thebes, where he is said to have been torn in pieces; that of Hercules at Tyre, where he was burnt with fire; that of Æsculapius in Epidaurus. And all these are spoken of, not only as men who have died, but as wicked men who have been punished for their crimes; and yet they are adored as gods by foolish men.
