of sight, and may be regarded at once as their most elementary form, and their highest degree of intensity’. M. Lélut knew the phenomenon among mystics whom he had observed in his practice as an ‘alienist’. He also quotes a story told of himself by Benvenuto Cellini. If we can admit that this hallucination of brilliant light may be produced in the conditions of a séance, whether modern, savage, or classical, we obtain a partial solution of the problem presented by the world-wide diffusion of this belief. Of course, once accepted as an element in spiritualism, a little phosphorus supplies the modern medium with a requisite of his trade. {68a}
Returning to Iamblichus, he classifies his phantasmogenetic agencies by the kind of light they show; greater or less, more or less divided, more or less pure, steady or agitated (ii. 4). The arrival of demons is attended by disturbances. {68b} Heroes are usually very noisy in their manifestations: a hero is a polter-geist, ‘sounds echo around’ (ii. 8). There are also subjective moods diversely generated by diverse apparitions; souls of the dead, for example, prompt to lust (ii. 9). On the whole, a great deal of experience is needed by the thaumaturgist, if he is to distinguish between one kind of manifestation and another. Even Inquisitors have differed in opinion.
Iamblichus next tackles the difficult question of imposition and personation by spirits. Thus a soul, or a spirit, may give itself out for a god, and exhibit the appropriate phantasmagoria: may boast and deceive (ii. 10). This is the result of some error or blunder in the ceremony of evocation. {69} A bad or low spirit may thus enter, disguised as a demon or god, and may utter deceitful words. But all arts, says our guide, are liable to errors, and the ‘sacred art’ must not be judged by its occasional imperfections. We know the same kind of excuses in modern times.
Porphyry went on to ask questions about divination and clairvoyance. We often ascertain the future, he says, in dreams, when our bodies are lying still and peaceful: when we are in no convulsive ecstasy such as diviners use. Many persons prophesy ‘in enthusiastic and divinely seized moments, awake, in a sense, yet not in their habitual state of consciousness’. Music of certain kinds, the water of certain holy wells, the vapours of Branchidæ, produce such ecstatic effects. Some ‘take darkness for an ally’ (dark séances), some see visions in water, others on a wall, others in sun or moon. As an example of ancient visions in water, we may take one from the life of Isidorus, by Damascius. Isidorus, and his biographer, were acquainted with women who beheld in pure water in a glass vessel the phantasms of future events. {70a} This form of divination is still practised, though crystal balls are more commonly used than decanters of water. Ancient and modern superstition as in the familiar case of Dr. Dee, attributes the phantasms to spiritual agency
Is a divine being compelled, Porphyry asks, to aid in these efforts, or is it only the soul of the seer, as some believe, which hallucinates itself, by the aid of points de repère? {70b} Or is there a blending of the soul’s operations with the divine inspiration? Or are demons in some way evolved out of something abstracted from living bodies? He seems to hint at some such theory of ‘exuvious fumes’ from the ‘circle,’ as more recent inquirers have imagined. The young appear to be peculiarly sensitive to vapours, invocations, and other magical methods, which affect the human constitution, and the young are usually engaged as seers. Hence visions are probably subjective. Ecstasy, madness, fasts and vigils seem particularly favourable to divination. Or are there certain mystic correspondences in the nature of things, which may be detected? Thus stones and herbs are used in evocations; ‘sacred bonds’ are tied (as in the Eskimo hypnotism and in Australia); closed doors are opened, the heavenly bodies are observed. Some suppose that there is a race of false and counterfeiting spirits, which, indeed, Iamblichus admits. These act the parts of gods, demons, and souls of the dead. Again, the conjurer plays on our expectant attention. Omitting some remarks no longer appropriate, Porphyry asks what use there is in chanting barbarous and meaningless words. He is inclined to think that the demon, or guardian spirit of each man is only part of his soul—in fact his ‘subliminal self’. And generally, he suspects that the whole affair is ‘a mere imaginative deceit, played off on itself by the soul’.
Replying as to divination, Iamblichus says that the right kind of dreams are between sleeping and waking when we hear a voice giving directions. A modern example occurred in the trial of the Assynt murderer in 1831. One Kenneth Fraser, called ‘the dreamer,’ said in the trial: ‘I was at home when I had the dream. It was said to me in my sleep by a voice like a man’s voice, that the pack (of the murdered pedlar) was lying in sight of the place. I got a sight of the place just as if I had been awake. I never saw the place before, but the voice said in Gaelic, “the pack of the merchant is lying in a cairn of stones, in a hollow near to their house”. The voice did not name Macleod’s house.’ The pack was, however, not found there, but in a place hard by, which Kenneth had not seen in his dream. Oddly enough, the murderer had originally hidden the pack, or some of its contents, in a cairn of stones, but later removed it. In the ‘willing game,’ as played by Mr. Stuart Cumberland, the seeker usually goes first to the place where the hider had thought of concealing the object, though later he changed his mind. Macleod was hanged, he confessed his guilt. {71}
Iamblichus believed in dreams of this kind, and in voices heard by men wide awake, as in the case of Joan of Arc. When an invisible spirit is present, he makes a whirring noise, like the Cock Lane Ghost! {72} Lights also are exhibited; the medium then by some mystic sense knows what the spirit means. The soul has two lives, one animal, one intellectual; in sleep the latter is more free, and more clairvoyant. In trance, or somnambulism, many cannot feel pain even if they are burned, the god within does not let fire harm them (iii. 4). This, of course, suggests Home’s experiments in handling live coals, as Mr. Crookes and Lord Crawford describe them. Compare the Berserk ‘coal-biters’ in the saga of Egil, and the Huron coal-biter in the preceding essay. ‘They do not then live an animal life.’ Sword points do not hurt them. Their actions are no longer human. ‘Inaccessible places are accessible to them, when thus borne by the gods; and they tread on fire unharmed; they walk across rivers. … They are not themselves, they live a diviner life, with which they are inspired, and by which they are possessed.’ Some are convulsed in one way, some in another, some are still. Harmonies are heard (as in Home’s case and that of Mr. Stainton Moses). Their bodies are elongated (like Home’s), or broadened, or float in mid-air, as in a hundred tales of mediums and saints. Sometimes the medium sees a light when the spirit takes possession of him, sometimes all present see it (iii. 6). Thus Wodrow says (as we have already shown), that Mrs. Carlyle’s ancestor, Mr. Welsh, shone in a light as he meditated; and Patrick Walker tells the same tale about two of the fanatics called ‘Sweet Singers’.
From all this it follows, Iamblichus holds, that spiritual possession is a genuine objective fact and that the mediums act under real spiritual control. Omitting local oracles, and practices apparently analogous to the use of planchette, Iamblichus regards the heavenly light as the great source of and evidence for the external and spiritual character and cause of divination (iii. 14). Iamblichus entirely rejects all Porphyry’s psychological theories of hallucinations, of the demon or ‘genius’ as ‘subliminal self,’ and asserts the actual, objective, sensible action of spirits, divine or daemonic. What effect Iamblichus produced on the inquiring Porphyry is uncertain. In his De Abstinentia (ii. 39) he gives in to the notion of deceitful spirits.
In addition to the evidence of Porphyry, Iamblichus, Eusebius and other authors of the fourth century, some recently published papyri of the same period throw a little light on the late Greek thaumaturgy. {73} Thus Papyrus cxxv. verso (about the fifth century) ‘contains elaborate instructions for a magical process, the effect of which is to evoke a goddess, to transform her into the appearance of an old woman, and to bind to her the service of the person using the spell. …’
Obviously we would much prefer a spell for turning an old woman into a goddess. The document is headed, yραυς Απολλου Τυανεως υπηρετις, ‘the old serving woman of Apollonius of Tyana,’ and it ends, η πραξις δεδοκιμασται, ‘it is proved by practice’.
