(9) But we must examine the fact that rivers are spoken of, and Wheels and Chariots attached to the Heavenly Beings. The rivers of fire signify the supremely Divine streams furnishing to them an ungrudging and incessant flow, and nourishing the productive powers of life; the chariots, the conjoined communion of those of the same rank; the wheels being winged, and advancing without turning and without deviation, the power of their advancing energy within a straight and direct path, towards the same unflinching and straight swoop of their every intellectual track, supermundanely straight and direct way. Also it is possible to explain, after another mystical meaning, the sacred description of the intellectual wheels; for the name Gel, Gel, is given to them, as the theologian says. This shews, according to the Hebrew tongue, revolutions and revelations. For the Empyrean and Godlike wheels have revolutions, indeed, by their perpetual movement around the Good Itself; but revelations, by the manifestation of things hidden, and by the elevation of things at our feet, and by the descending procession of the sublime illuminations to things below. There remains for accurate explanation, the statement respecting the rejoicing of the Heavenly Orders; for they are utterly incapable of our impassioned pleasure. Now they are said to rejoice with God over the discovery of what was lost, as befits their Divine good nature, and that Godlike and ungrudging rejoicing over the care and salvation of those who are turned to God; and that joy, beyond description, of which also holy men often partake, whilst the deifying illuminations of the Deity rest upon them. Let it suffice, then, to have said this much concerning the Divine representations, which, no doubt, falls short of their accurate explanation, but which will prevent us, I think, from being servilely entangled in the resemblance of the types. But if you should say that we have not mentioned in order the whole Angelic Powers, or operations, or likenesses, depicted in the Oracles, we answer in truth, that we do not possess the supermundane science of some; and further, in regard to them, we have need of another to conduct to light and to reveal. Other things, however, as being parallel to the things said, we have omitted, out of regard to the symmetry of the discourse; and the hiddenness, beyond our capacity, we have honoured by silence.
