“There are some mixt bodies, from which it has not been yet made appear, that any degree of fire can separate either salt, or sulphur, or mercury, much less all the three. The most obvious instance of this truth is gold, which is a body so fixed, and wherein the elementary ingredients (if it have any) are so firmly united to each other, that we find not in the operations, wherein gold is exposed to the fire, how violent soever, that it does discernably so much as lose of its fixedness or weight, so far is it from being dissipated into those principles, whereof one at least is acknowledged to be fugitive enough.”

“But I will not... trouble you with what I have largely discoursed in the Sceptical Chymist, to call in question the grounds on which Chymists assert, that all mixt bodies are compounded of Salt, Sulphur, and Mercury. For it may suffice me now to tell you that, whatsoever they may be able to obtain from other bodies, it does not appear by Experience, which is the grand, if not the onely, Argument they rely on, that all mixt bodies that have Qualities consist of their tria prima, since they have not been able, that we know, truly, and without new Compositions, to resolve into those three, either Gold, or Silver, or Crystal, or Venetian Talck, or some other bodies, that I elsewhere name; & yet these bodies are endowed with divers Qualities, as the two former with Fusibleness and Malleability, and all of them with Weight and Fixity; so that in these and the like bodies, whence Chymisats have not made it yet appear, that their Salt, Sulphur and Mercury, can be truly and adequately separated, 'twill scarce be other than precarious to derive the malleableness, colour, and other Qualities of such bodies from those Principles.”

“As for silver, I never could see any degree of fire make it part with any of its three principles. …But admitting, that some parts of the silver were driven away by the violence of the fire, what proof is there, that it was either the salt, the sulphur, or the mercury of the metal, and not rather a part of it homogeneous to what remained? for besides that the silver, that was left, seemed not sensibly altered, which probably would have appeared, had so much of any one of its principles been separated from it.”

“They wonder much to hear that gold, which in itself is so useless a thing, should be everywhere so much esteemed, that even men for whom it was made, and by whom it has its value, should yet be thought of less value than it is.”

“I need not tell you, what complaints the more candid and judicious of the Chymists themselves are wont to make of those boasters, that confidently pretend, that they have extracted the salt or sulphur of quicksilver, when they have disguised it by additaments, wherewith it resembles the concretes, whose names are given it; whereas by a skilful and rigid examen, it may be easily enough stripped of its disguises, and made to appear again in the pristine form of running mercury. The pretended salts and sulphurs being so far from being elementary parts extracted out of the body of mercury, that they are rather… de-compound bodies, made up of the whole metal and the menstruum, or other additaments employed to disguise it.”

“It is somewhat strange to me, that neither the Spagyrists themselves, nor yet their Adversaries, should have taken notice that Chymists have rather supposed than evinced, that the Analysis of bodies by fire, or even that at least some Analysis is the onely instrument of investigating what Ingredients mixt bodies are made up of, since in divers cases That may be discovered by Composition as well as by Resolution; as it may appear, that Vitriol consists of metalline parts (whether Martial, or Venereal, or both) associated by Coagulation with acid ones, one may, I say, discover this as well by making true Vitriol with Spirit (improperly called Oil) of Sulphur, or that of Salt, as by distilling or Resolving Vitriol by the fire.”

“As much as is iron, so much is fire;
And as much as is fire, so much is iron;
Yet the iron doth not become fire,
Nor the fire iron,
But each retains its substance and nature.
So likewise the spirit of man doth not become God,
But is deified,
And knows itself breadth, length, height and depth:
And as far as God is God,
So far the loving spirit is made one with Him
In love.”

John Ruysbroeck (1293–1381) Flemish mystic

The Twelve Beguines

“In heaven His throne is made of gold,
Where the ark of His testament is stowed,
A throne from which I'm told all history does unfold,
Down here it's made of wood and wire,
And my body is on fire,
And God is never far away.”

“In this instance of the fire-arms, the Asiatic has been most improperly bracketed with the native. The British Indian does not need any such restrictions as are imposed by the Bill on the natives regarding the carrying of fire-arms. The prominent race can remain so by preventing the native from arming himself. Is there a slightest vestige of justification for so preventing the British Indian?”

“The great gold planet that is the mourning heat of the Sun
Is greater than all gold, more powerful
Than the tawny body of a Lion that fire consumes
Like all that grows or leaps… so is the heart
More powerful than all dust.”

Edith Sitwell (1887–1964) British poet

Green Song & Other Poems (1944), Heart and Mind

“Fir: it contains a great deal of air and fire with very little moisture and the earthy, so that, as its natural properties are of the lighter class, it is not heavy. Hence, its consistence being naturally stiff, it does not easily bend under the load, and keeps its straightness when used in the framework. But it contains so much heat that it generates and encourages decay, which spoils it; and it also kindles fire quickly because of the air in its body, which is so open that it takes in fire and so gives out a great flame.”
