Demons in the moon: migration of the soul.
These suggestions that the moon and the air between earth and moon are the abode of the demons and this reminiscence of the Platonic doctrine of the soul and its migrations receive further confirmation in a discussion whether the moon is inhabited in the essay, On the Face in the Moon. A story is there told[935] of a man who visited islands five days’ sail west of Britain, where Saturn is imprisoned and where there are demons serving him. This man who acquired great skill in astrology during his stay there stated upon his return to Europe that every soul after leaving the human body wanders for a time between earth and moon, but finally reaches the latter planet, where the Elysian fields are located, and there becomes a demon.[936] The demons do not always remain in the moon, however, but may come to earth to care for oracles or be imprisoned in a human body again for some crime.[937] The man who repeats the stranger’s story leaves it to his hearers, however, to believe it or not. But the struggle upward of human souls to the estate of demons is again described in the essay on the demon of Socrates,[938] where it is explained that those souls which have succeeded in freeing themselves from all union with the flesh become guardian demons and help those of their fellows whom they can reach, just as men on shore wade out as far as they can into the waves to rescue those sea-tossed, ship-wrecked mariners who have succeeded in struggling almost to land. The soul is plunged into the body, the uncorrupted mind or demon remains without.[939]
Demons mortal: some evil.
The demons differ from the gods in that they are mortal, though much longer-lived than men. Hesiod said that crows live nine times as long as men, stags four times as long as crows, ravens three times as long as stags, a phoenix nine times as long as a raven, and the nymphs ten times as long as the phoenix.[940] There are storms in the isles off Britain whenever one of the demons residing there dies.[941] Some demons are good spirits and others are evil; some are more passive and irrational than others; some delight in gloomy festivals, foul words, and even human sacrifice.[942]
Men and demons.
Once a year in the neighborhood of the Red Sea a man is seen who spends the remainder of his time among “nymphs, nomads and demons.”[943] At his annual appearance many princes and great men come to consult him concerning the future. He also has the gift of tongues to the extent of understanding several languages perfectly. His speech is like sweetest music, his breath sweet and fragrant, his person the most graceful that his interlocutor had ever seen. He also was never afflicted with any disease, for once a month he ate the bitter fruit of a medicinal herb. As to the exact nature of Socrates’ demon there is some diversity of opinion. One man suggests that it was merely the sneezing of himself or others, sneezes on the left hand warning him to desist from his intended course of action, while a sneeze in any other quarter was interpreted by him as a favorable sign.[944] The weight of opinion, however, inclines towards the view that his demon did not appear to him as an apparition or phantasm, or even communicate with him as an audible voice, but by immediate impression upon his mind.[945]
Relation of Plutarch’s to other conceptions of demons.
Plutarch’s account of demons is the first of a number which we shall have occasion to note. As the discussion of them by Apuleius in the next chapter and the rather crude representation of them given in Philostratus’s Life of Apollonius of Tyana will show, there was as yet among non-Christian writers no unanimity of opinion concerning demons. On the other hand there are several conceptions in Plutarch’s essays which were to be continued later by Christians and Neo-Platonists: namely, the conception of a mediate class of beings between God and men, the hypothesis of a world of spirits in close touch with human life, the association of divination and oracles with demons, and the location of spirits in the sphere of the moon or the air between earth and moon,—although Plutarch sometimes connected demons with the stars above the moon. This occasional association of stars with spirits and of sinning souls with falling stars bears some resemblance to the depiction of certain stars as sinners in the Hebraic Book of Enoch, which was written before Plutarch’s time and which we shall consider in our next book as an influence upon the development of early Christian thought.
The astrologer Tarrutius.
As for the stars apart from demons, Plutarch discusses the art of astrology as little as he does “magic” by that name. Mentions of individuals as skilled in “astrology” may simply mean that they were trained astronomers. When a veritable astrologer in our sense of the word is mentioned in one of Plutarch’s Lives,[946] he is described as a μαθηματικός—a word often used for a caster of horoscopes and predicter of the future. Here, however, it carries no reproach of charlatanism, since in the same phrase he is called a philosopher. This Tarrutius was a friend of Varro, who asked him to work out the horoscope of Romulus backward from what was known of the later life and character of the founder of Rome. “For it was possible for the same science which predicted man’s life from the time of his birth to infer the time of his birth from the events of his life.” Tarrutius set to work and from the data at his disposal figured out that Romulus was conceived in the first year of the second Olympiad, on the twenty-third day of the Egyptian month Khoeak at the third hour when there was a total eclipse of the sun; and that he was born on the twenty-first day of the month Thoth about sunrise. He further estimated that Rome was founded by him on the ninth day of the month Pharmuthi between the second and third hour. For, adds Plutarch, they think that the fortunes of cities are also controlled by the hour of their genesis. Plutarch, however, seems to look upon such doctrines as rather strange and fabulous.[947] Varro, on the other hand, may have regarded it as the most scientific method possible of settling disputed questions of historical chronology
