That their so-called good demons are agents of death

"Already in other cases some have been shown to be servants of certain gods, as Pan of Dionysus; and Apollo at Branchidae has shown this through the following. For nine men were found dead; and when those who lived in the countryside asked the cause, the god gave this oracle: 'Pan, golden-horned servant of grim Dionysus, going over the wooded mountains, held a staff in his strong hand, and in the other grasped a hollow pipe sounding clear, and charmed the hearts of the Nymphs. Piping a shrill tune he terrified all the woodcutters, and amazement seized them as they saw the chilling form of the raging demon rushing on. And the end of chilling death would have seized them all, had not Artemis the huntress, holding dread anger in her breast, checked his mighty fury; to her you must pray, that she may be your helper.'" You have heard what the Apollo at Branchidae says of the form and deeds of the demon whom he calls good. Look now at the noble achievements of the rest, for whose sake they left their heavenly abode and exchanged it for life among men.⁠a They surely ought to have led the way in self-control and suggested to men what is profitable and useful. But they did none of these things. Listen to what he reveals who has searched out the secrets more secret than secrets and been counted worthy of the knowledge of hidden things. He says that some of these good demons minister to erotic pleasures, others delight in drums and flutes and the clatter of women, others again exult in battles and wars; Artemis in hunting and Deo in the fruits of the earth; Isis still mourns Osiris, and Apollo gives oracles. Such are the benefits to men of those they call good demons. Receive the proofs of these things too.
