Not to forget the visions of brilliant light in Dante’s Paradise and which have been depicted in their maximum splendor by a nineteenth-century artist, Gustave Doré, who sought (as only he could) to depict those scenes of radiance, those flaming vortexes, those lamps, those suns, that clearness that hides “like an horizon brightening with the dawn” (canto 14, line 69), those white roses, those rubicund flowers that shine out in the third part of The Divine Comedy, where even the vision of God appears like an ecstasy of fire:
Within Its depthless clarity of substance
I saw the Great Light shine into three circles
in three clear colours bound in one same space;
the first seemed to reflect the next like rainbow
on rainbow, and the third was like a flame
equally breathed forth by the other two.
(canto 33, lines 115–20; translated by Mark Musa)
The Middle Ages was dominated by a cosmology of light. Already by the ninth century John Scotus Eriugena said, “This universal manufactory of the world is a vast lamp consisting of many parts like many lights to reveal the pure species of intelligible things and to sense them with the mind’s eye, instilling divine grace and the help of reason into the heart of learned followers. It is right then that the theologian calls God the Father of Enlightenment, since all things are from Him, for which and in which He manifests himself and in the light of the lamp of his wisdom he unifies and makes them” (Commentary on the Celestial Hierarchy, chapter 1).
In the thirteenth century the cosmology of light put forward by the English churchman Robert Grosseteste built up a picture of the universe formed by a single flow of luminous energy, a source both of beauty and being, making us think of a sort of Big Bang. The astral spheres and natural areas of the elements are created from the single light by gradual rarefaction and condensation, producing the infinite shades of color and the volumes of things. Saint Bonaventure of Bagnoregio (Commentary on the Book of Sentences, book 2, distinction 12, chapters 1 and 2) was to record that light is the common nature found in all bodies, whether celestial or terrestrial; light is the substantial form of bodies, and the more they possess it, the more they are a real and worthy part of existence.
HELLFIRE
But while fire moves across the sky and shines down on us, it likewise erupts from the bowels of the earth, bringing death. Thus, from the very earliest times, fire has also been associated with the infernal depths.
In the book of Job (41:19–21), from the mouth of Leviathan “go burning lamps, and sparks of fire leap out . . . His breath kindleth coals, and a flame goeth out of his mouth.” In Revelation, when the seventh seal is broken, hail and fire come to devastate the earth, the bottomless pit opens up, and from it emerge smoke and locusts; the four angels, set loose from the river Euphrates where they were bound, move with countless armies of men wearing breastplates of fire. And when the Lamb reappears and reaches the supreme judge on a white cloud, the sun burns the survivors. And, after Armageddon, the beast and the false prophet will be thrown into a lake of burning sulfurous fire.
In the Gospels, sinners are cast into everlasting fire:
As therefore the tares are gathered and burned in the fire; so shall it be in the end of this world. The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity; And shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth. (Matthew 13:40–42)
Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels. (Matthew 25:41)
Curiously, in Dante’s inferno there is less fire than we might expect, since the poet contrives to think up a whole range of torments, but we may be satisfied with heretics lying in fiery tombs; men of violence plunged into pools of blood; blasphemers, sodomites, and usurers struck by rains of fire; simoniacs shoved head-first into pits, with flames lapping at their feet; and barrators submerged in boiling pitch.
Hellfire was certainly more prevalent in baroque writings, with descriptions of the torments of hell that exceed the violence of Dante, not least because they are unredeemed by the inspiration of art—like this passage by Saint Alphonsus de Liguori:
The punishment that most torments the senses of the damned, is the fire of hell . . . Even in this life, the pain of fire is the greatest of all; but there is much difference between our fire and that of hell which, says Saint Augustine, makes ours seem painted . . . Thus the wretched will be surrounded by fire, like wood inside a furnace. The damned will find themselves with an abyss of fire beneath, an abyss above, and an abyss around them. If they touch, see or breathe, they will touch, see or breathe nothing but fire. They will be in the fire like fish in water. But this fire will not only surround the damned, but will enter even their bowels to torment them. Their body will become all fire, so that their bowels will burn within their belly, their heart within their breast, their brains within their head, their blood within their veins, even their marrow with their bones: every lost soul will become in himself a furnace of fire. (Apparecchio alla morte, consideration 26)
And Ercole Mattioli, in Pietà illustrate (1694), wrote,
Great wonder will it be that a fire alone contains perfectly within it, according to great theologians, the coldness of ice, the stings of thorns and iron, the venom of asps, the poisons of vipers, the cruelty of all wild beasts, the malevolence of all elements and stars . . . Yet greater wonder, et supra virtutem ignis, will be that such fire, though one specie alone, can make distinction in tormenting those who sin most, being called by Tertullian sapiens ignis, and by Eusebius of Emesa ignis arbiter, since, having to match, according to the greatness and diversity of supplicants, the greatness and diversity of their sins . . . , the fire, almost as if it were endowed with reason and full knowledge, to distinguish between sinner and sinner, shall make its rigors felt with more or less severity.
And so we arrive at the last secret of Fatima by Sister Lucia, exshepherdess:
The secret consists of three distinct parts, two of which I am now going to reveal. The first part is the vision of hell. Our Lady showed us a great sea of fire, which seemed to be underground. Plunged in this fire were demons and souls in human form, like transparent burning embers, all blackened or burnished bronze, floating about in the conflagration, now raised into the air by the flames that issued from within themselves together with great clouds of smoke, now falling back on every side like sparks in a huge fire, without weight or equilibrium, and amid shrieks and groans of pain and despair, which horrified us and made us tremble with fear. The demons could be distinguished by their terrifying and repulsive likeness to frightful and unknown animals, all black and transparent. (Congregation for the Doctrine of the Faith, The Message of Fatima, June 26, 2000)
ALCHEMICAL FIRE
Halfway between holy fire and hellfire is fire as an alchemical operator. Fire and crucible seem to be essential in alchemical practice, which seeks to operate on a raw material so as to obtain from it, through a series of manipulations, the philosopher’s stone. This is capable of projection, transmuting base metals into gold.
The manipulations of the raw material take place through three stages, distinguished by the color the material gradually assumes: the black work, the white work, and the red work. The black work involves a heating (and therefore the use of fire) and decomposition of the matter, the white work is a process of sublimation or distillation, and the red work is the final stage (red is the color of the sun, which often symbolizes gold, and vice versa). The hermetical furnace, the athanor, is an essential instrument, but alembics, vessels, and mortars are also used, each with their symbolic names, such as the philosophical egg, maternal womb, wedding chamber, pelican, sphere, sepulcher, and so forth. The essential substances are sulfur, mercury, and salt. But the procedures are never clear, since the language of alchemists is based on three principles:
