The works of the highly experienced and famous chymist, John Rudolph Glauber

by Johann Rudolf Glauber

But verily this cannot be rational, because those burning Mountains have a natural Original, and Cause of Fireing, known but to very few; for in some places are found Mountains wholly Sulphure which being kindled, either by the Central or Elemental fire of Thunder, or any other accident cannot but burn, and when such a Mountain hath but once taken Fire, and begins to burn, who can restrain the burning; no body, because of the greatness of the Fire, and danger of what may happen, being therefore left to it self, it feeds downwards, being never destitute of matter fit for the fire.

And now if any one understanding by the Monuments of the Antients, that these Mountains have burned for some Ages, yea, and for Thousands of Years, should wonder, whence Fuel sufficient for that Fire should be had, let him know, that this may easily be done; that a Mountain should burn without intermission, not only for the magnitude of the Terrene Globe, in which a mountainous Wax, or Bitumen, Brimstone, and such like Combustible Things abound: But also, because of the never-interrupted Motion of the Stars, whereby they never cease replenishing the Earth with their out-flowings, and generating (besides Minerals) such Combustible matters as these, augmenting and cherishing the Fire.

But they endeavour to confirm their Opinion by the lamentable Howlings, which at some times are heard nigh those Mountains; which Cryes, the credulous Vulgar People report to be of the Souls, which are lost: But these are but Trifles; for those Out-cryes are then only uttered, when the Mountains endeavour to throw out much fire, otherwise they burn and fume very gently, which as soon as the Adjacent Inhabitants perceive, they well know, that they shall shortly have an Harvest of ashes, fire, & stones, out of the Mountains: and that they may avoid the hazard and danger threatned by the Fire, they carefully keep far enough off. And for the most part, a great Quantity of the Sulphure is prepared in the neighbouring parts, whereby the needy get their food, by digging it up, purging it from its Impurities, and preparing it for humane uses; but as to the Cryes, it seems to be nothing else in my opinion, but only the fire breaking forceable through the streight Channels, the hard Stones and Caverns, and produceing thereby a dreadful sound, which they commonly call Ejulation, or Howling. They also add, that about those fiery Mountains, Ghosts, Visions, and Spirits usually appear visibly. This also is true, and Grounded upon Nature, but yet thou canst not prove that they are Devils and infernal Spirits; there being even otherwhere seen, and found diverse Spirits in the Bowels of the Earth, being Monsters not unwonted, or strange to such as dig, or are Miners, by which they are frequently injured; yea, and sometimes destroyed, lamed or infected; sometimes these spirits are hurtless and idle spectators, or playing with the workmens implements; or even labour themselves not in the least filling their Pockets, how strongly soever they shew themselves bent upon their work. But such spirits appear in various forms, oftentimes resembling an Horse, a Dog, or other Beast, sometimes a Dwarf-like crooked man; frequently they appear cloathed with an ashy Cowle of a Monk; they usually are Testimonies of great Felicity and rich Mines; sometimes they do great mischief, by choaking the Miners with a wicked habit, or throwing them headlong into the Pits, by reason of whose malice many of the rich Mines are unavoidable left undigged, they boldly defending their hidden Treasures.

Let these things concerning the spirits, about the burning Mountains, or those remaining in the profundity of the Earth, and appearing in the several shapes, be spoken by way of Parenthesis. And now I return to the thing in hand, and will demonstrate, that there is nothing of Community betwixt these burning Mountains and the central or infernal fire, but that these blow out a thick and material fire; which I thus prove.

First of all, These Mountains do at sometimes cease to burn, breathing out smoak only between whiles more copiously: sometimes they dye and expire through want of fuel to supply them.

But the central fire can never be either diminished or vanish as long as the sun shines and starrs glister, and send down their vertues into the earths centre. Even as the infernal fire shall never expire, the Scripture thus testifying, wherefore that fire, though a most furious Mountainous fire, cannot be either of these two, but is meerly material, subject to encrease and decrease, and its food desisting, plainly extinguisheth: Besides, the fire of those Mountains heats not fervently, but for the greatest part smoke obscurely; but the adjoyning Earth is very hot, for the space of some miles, so that you cannot long stand there without injuring your feet. The Waters also which slow down from them, are boyling hot, and manifestly smell of sulphur a good Portion whereof they have within themselves.

Besides these flaming and smoaking Mountains, there are sometimes found other Denns or Caverns, breathing forth neither Flame nor Fume, and yet a great heat, which is another kind of fire, which is largely treated of in the Chronicles of Metals, where amongst other things, this is also added; That on a time a Wind gaping, arose in a certain Mountain, and sent forth a huge heat, and in the night only was some splendor perceptible, ascending towards Heaven, and sometimes a breathing heat was only observed.

On this a curious Monk was in himself perswaded to let down into the cranny, a pot, bound on an Iron Chain, with intent to draw up some molten Gold, which he believed to be thereunder, which when it came to touch the fire, it presently melted and fell down, the which in like sort burnt away like Chaff, with a good part of the Chain also, and was ejected and thrown up again in the form of a fume, with a great noise and crack, but the Monk hardly scap’d with his life, the gold being left behind in the Hell; but thou maist readily divine what sort of fire this was, which reduced the Pot and Chain into fume in the twinkling of an eye, that it was not a material fire, because void of smoak, but the astral fire.

It is well known to the Miners, that the central and gehennal fire doth oftentimes ascend the high parts of the Mountains, and warm them, and there cherish and maturate the metals: which Caverns, when in their searching for Metals, they come nigh unto, they feel too much heat, that they are even against their wills compelled to desist. But this heat, although indeed in the action of the growing, Minerals doth usually excite and make great enough; yet for the greatest part it derives its Original from the central fire, and this central from the Starrs. But after what manner and reason the starrs beget the central fire, and this generates the Minerals and Metals, I will demonstrate to the unknowing as briefly as I can.

Thus therefore stands the case: We read in Moses, in the first of Genesis, that God, when he made the World out of the confused Chaos, did give the Elements their original first, and assigned to Earth its proper place, and injoyned on earth its Office to be done; but by what means they are preserved by the interceding perpetual Circulation, natural Philosophy doth demonstrate. It will not therefore be to our purpose to treat prolixly of them, but only of the rise and nativity of metals, will I compendiously speak as far as I know of them, viz. in what manner the metallick kind draws its original from them, together with its encrease and augmentation, and how having arrived to the top of their perfection, they come to their end.
