In the Old Testament, we likewise read of several apparitions of angels, which can hardly be explained but as of guardian angels; for instance, the one who appeared to Hagar in the wilderness, and commanded her to return and submit herself to Sarah her mistress;[66] and the angel who appeared to Abraham, as he was about to immolate Isaac his son, and told him that God was satisfied with his obedience;[67] and when the same Abraham sent his servant Eleazer into Mesopotamia, to ask for a wife for his son Isaac, he told him that the God of heaven, who had promised to give him the land of Canaan, would send his angel[68] to dispose all things according to his wishes. Examples of similar apparitions of tutelary angels, derived from the Old Testament, might here be multiplied, but the circumstance does not require a greater number of proofs. Under the new dispensation, the apparitions of good angels, of guardian spirits, are not less frequent in most authentic stories; there are few saints to whom God has not granted similar favors: we may cite, in particular, St. Frances, a Roman lady of the sixteenth century, who saw her guardian angel, and he talked to her, instructed her, and corrected her.

CHAPTER V. OPINION OF THE GREEKS AND ROMANS ON THE APPARITIONS OF GOOD GENII. Jamblichus, a disciple of Porphyry,[69] has treated the matter of genii and their apparition more profoundly than any other author of antiquity. It would seem, to hear him discourse, that he knew both the genii and their qualities, and that he had with them the most intimate and continual converse. He affirms that our eyes are delighted by the appearance of the gods, that the apparitions of the archangels are terrible; those of angels are milder; but when demons and heroes appear, they inspire terror; the archontes, who preside over this world, cause at the same time an impression of grief and fear. The apparition of souls is not quite so disagreeable as that of heroes. In the appearance of the gods there is order and mildness, confusion and disorder in that of demons, and tumult in that of the archontes. When the gods show themselves, it seems as if the heavens, the sun and moon, were all about to be annihilated; one would think that the earth could not support their presence. On the appearance of an archangel, there is an earthquake in every part of the world; it is preceded by a stronger light than that which accompanies the apparition of the angels; at the appearance of a demon it is less strong, and diminishes still more when it is a hero who shows himself.
