Book 12
35. We have also heard of someone suffering from an unclean spirit, who while confined to his house used to announce when a presbyter from twelve miles away was setting out to visit him, and then say where he had got to through all the stages of his journey, and how near he was getting, and when he entered the estate, and the house, and the bedroom, until he stood there in front of him. […]
He would not take any food from his own family, but only from that presbyter. He used to put up a violent resistance against his family, as much as his strenght allowed him to, and only when that presbyter arrived would be quiet down, and submit only to him and answer him submissively. His loss of wits however, or demonic possession, did not give way even to the presbyter, except when he was cured of his fever, as delirious people usually are cured, and after that he did not experience the same sort of thing again.
