Chapter XI-a
Another species of divine divination which is much celebrated, most manifest and manifold, is that of oracles, about which you say as follows: “ There are some who drink water, as the priest of Clarius, in Colophon; but others are seated at the mouth [of a cavern], as those who prophesy at Delphi; and others imbibe the vapour from water, as the prophetesses in 141 Brandchidæ .” You have, therefore, made mention of these three oracles by name, not that there are only these, for there are many more which you have omitted, but as these are more celebrated than the rest, and, at the same time, because through these you may be sufficiently instructed in the mode of divination sent to men from the Gods, hence, as it appears to me, you were satisfied with these.
We, therefore, likewise shall discuss these three, omitting to speak about the many other oracles that exist.
It is acknowledged then by all men, that the oracle in Colophon gives its answers through the medium of water.
For there is a fountain in a subterranean dwelling from which the prophetess drinks; and on certain established nights, after many sacred rites have been previously performed, and she has drank of the fountain, she delivers oracles, but is not visible to those that are present.
That this water, therefore, is prophetic, is from hence manifest.
But how it becomes so, this, according to the proverb, is not for every man to know.
For it appears as if a certain prophetic spirit pervaded through the water.
This is not, however, in reality the case.
For a divine nature does not 142 pervade through its participants in this manner, according to interval and division, but comprehends as it were externally, and illuminates the fountain, and fills it from itself with a prophetic power.
For the inspiration which the water affords is not the whole of that which proceeds from a divine power, but the water itself only prepares us, and purifies our luciform spirit, so that we may be able to receive the divinity; while, in the mean time, there is a presence of divinity prior to this, and illuminating from on high.
And this, indeed, is not absent from any one, who through aptitude is capable of being united to it.
But this divine illumination is immediately present, and uses the prophetess as an instrument; she neither being any longer mistress of herself, nor capable of attending to what she says, nor perceiving where she is.
Hence, after prediction, she is scarcely able to recover herself.
And before she drinks the water, she abstains from food for a whole day and night; and retiring to certain sacred places, inaccessible to the 143 multitude, begins to receive in them the enthusiastic energy.
Through her departure, therefore, and separation from human concerns, she renders herself pure, and by this means adapted to the reception of divinity: and from hence she possesses the inspiration of the God, shining into the pure seat of her soul, becomes full of an unrestrained afflatus, and receives the divine presence in a perfect manner, and without any impediment.
But the prophetess in Delphi, whether she gives oracles to mankind through an attenuated and fiery spirit, bursting from the mouth of the cavern, or whether being seated in the adytum on a brazen tripod, or on a stool with four feet, she becomes sacred to the God; whichsoever of these is the case, she entirely gives herself up to a divine spirit, and is illuminated with a ray of divine fire.
And when, indeed, fire ascending from the mouth of the cavern circularly invests her in collected abundance, she becomes filled from it with a divine splendour.
The ritual practice of discerning hidden knowledge — future events, concealed causes, or the will of higher powers — through a structured technique applied to cards, lots, astrological configuration, entrails, oracle, or other sortilege, rather than through direct unmediated insight. Distinct from gnosis_direct_knowledge (unmediated inner apprehension of ultimate truth, not a technique applied to an external medium) and cosmic_sympathy (the underlying doctrine of hidden affinity that many divinatory techniques presuppose, rather than the practice of consulting it).
The entire passage is a systematic discussion of oracular divination—three named oracles (Colophon, Delphi, Branchidæ) and the mechanisms by which hidden knowledge is discerned through structured techniques (drinking water, sitting at a cavern mouth, imbibing vapour).
The doctrine that the divine is present within all things and the universe itself, pervading creation rather than remaining solely transcendent above it. Distinct from unity_of_being (the general claim that all existence is one substance, agnostic about whether that substance indwells its parts) and from kingdom_within (the divine present specifically IN THE INDIVIDUAL human, accessible without mediation) — divine_immanence is the general pervading-presence claim applied to all of creation, not a human-specific indwelling.
The divine 'illuminates the fountain, and fills it from itself with a prophetic power' and is 'not absent from any one, who through aptitude is capable of being united to it'—the divine actively pervades and is present within specific material loci and persons.
Ecstatic irrational rapture — Plato's mania, Bruno's furore — by which the soul transcends ordinary reason and attains direct contact with divine reality; madness reframed as higher knowledge.
The passage describes the prophetess entering a state of ecstatic irrationality—'enthusiastic energy,' 'unrestrained afflatus,' loss of self-awareness and self-control—by which she receives divine knowledge, precisely the Platonic mania reframed as higher contact with the divine.
A chain of divine beings or principles flowing downward from a single transcendent source (the One or the Father), each level less perfect than the one above.
The passage describes a clear downward flow: divine presence 'from on high' illuminates the fountain, fills it with prophetic power, which then prepares the prophetess—each level mediating the divine to the next, with the divine 'comprehending externally' rather than dividing itself.
A non-physical dimension of reality, interpenetrating the physical world, populated by forces, beings, and forms ordinarily imperceptible to physical senses and instruments, that can affect embodied life without being seen — Dion Fortune's 'mind-side of nature,' the astral plane of Western esotericism broadly construed. Distinct from astral_light (a specific transmitting medium or fluid operating within this realm, not the realm itself), pleroma (the divine fullness at the summit of a cosmic hierarchy, not a parallel plane coextensive with ordinary life), and animism (particular indwelling spirits bound to specific natural objects, not the general unseen dimension itself).
The passage describes a non-physical dimension of divine presence that 'illuminates from on high,' a 'prophetic spirit' that operates through water without being reducible to it, and a 'luciform spirit' that is purified to receive divinity—all imperceptible to physical senses yet affecting embodied life.
The state of a person being controlled or inhabited by an external spirit or entity — the entity as subject acting through the person's body, rather than merely troubling them from without. Distinct from haunting (a discarnate soul or place-bound presence that interferes without necessarily entering and controlling a living body) and from spirit_conjuration (an operator deliberately commanding a spirit's appearance, the reverse relation — here the spirit is uninvited and in control, not summoned and subordinated).
The prophetess is explicitly described as 'neither being any longer mistress of herself, nor capable of attending to what she says, nor perceiving where she is,' and as being 'full of an unrestrained afflatus' with the divine presence using her 'as an instrument'—a textbook case of divine possession.
At Delphi, 'fire ascending from the mouth of the cavern circularly invests her in collected abundance, she becomes filled from it with a divine splendour'—fire is explicitly the medium of divine presence and theurgical operation.
The maintenance of a state of cleanliness—physical, moral, or spiritual—required for encounter with the divine.
The passage explicitly details purification rituals such as fasting, abstaining from food, and retiring to sacred places before receiving divine presence.
The doctrine — central to Eastern Orthodox and Maximian theology — that the human person is progressively transformed into a partaker of the divine nature by grace, not merely justified or united in passing ecstasy.
The prophetess is described as being filled with a prophetic power and possessing the inspiration of the God.
Iamblichean ritual practice that engages the gods directly through consecrated material symbols and actions, on the premise that divine power descends into properly prepared matter — distinct from philosophical contemplation alone.
The passage describes specific consecrated rites, purification, and ritual preparation required for the encounter with the divine.
