John Chrysostom — as excerpted in the Catena Aurea on Luke 8:26-39

“(Hom. 28. in Matt.) Or, Luke selected from the two the one who was most savage. Hence he gives the most melancholy account of his calamity, adding, And he wore no clothes, neither abode in any house, but in the tombs. But the evil spirits visit the tombs of the dead, to instil into men that dangerous notion, that the souls of the dead become evil spirits.”
