Clearly and perspicuously revealing and declaring, (for the benefit and profit’s sake of the whole Countrey) by what means those three Arcana’s promised in the said fifth part are to be advantageously effected. Together with an adjoyned Explication of some obscurer places which are not so clearly disclosed in the third and fourth parts of the Prosperity of Germany, as likewise in the first Century.

Friendly Reader,

I doubt not, but it will seem a wonder to many, that Arcana’s of so great moment and so much utility should be laid open by me, in so perspicuous and evident a description, as for every one thoroughly to know them.

However, any Body may easily perswade himself that I have not so done without weighty causes, which to reckon up here at present, I judge it not so altogether necessary, but that it will be more commodious to refer it to some other convenient time. The chiefest and which is the most over-swaying reason amongst all the rest, is this, viz. the perverseness of some abusive Men, not onely endeavouring to make my Writings envied [or hated] by Men of common rank, but also by the great ones, by their lying reproachfull slaunders; and especially most falsely averring, that those three Arcana’s which I promised in the [Fifth Part of the Prosperity of Germany], are of no profit, and therefore cannot be effected with any advantage, and that I my self sought after nothing else by promising their discovery, save onely by imposing them upon [or selling them unto] others to scrape some Monies together. Now forasmuch as this is the property of Slanders, to be admitted far easilier and readilier than the truth it self, and that for this reason many have diverted their minds from the truth of this thing by busying them about these Calumnies, and so have not known how the case stands; but (on the contrary) seeing I am conscious of mine own Innocency, and am far wide of those Crimes so falsely charged on me, I have judged it most just and most highly necessary, not to suffer those most false Accusations to rest upon me, but to shew the contrary to the Eyes of the whole World, and by demonstrating and disclosing the very truth it self, to recover my honour so perfidiously and treacherously snatcht from me; the which could not possibly be done by any better way than this.

Necessity therefore required the Work it self to speak, and to defend its own self, which indeed is a true and genuine defence, and way of stopping the shameless and lying Mouths of all reproachfull Slanderers. God will in time recompence such false Mens most wicked Works, whereby they have exceedingly injured me. Mean while every one may apply these most profitable inventions to their use, and undertake the doing one or other of the Operations whereby they may reap some benefit, which I wish them from my Soul.

Nor do I doubt, but that a very many Men will, by following the Doctrine by me prescribed, and insisting upon the foot-steps of my Writings, which are founded on the truth, as being a sure Foundation, get themselves no small profit; whilest they quietly and peaceably enjoy the gainfull practising on my Arcana’s: And especially of that most easie secret, by which, fugacious and volatile Gold is extracted out of all kinds of Flints, (every where plentifully offering themselves, and so by the help of Lead, is rendred Corporeal. Which Work verily is such, as that one Man doth no ways damnifie another by, but may rather help and profit him. Therefore do I at present affirm to every body with that truth which God loves, and will defend, that all the following Operations which I manifest in the publishing this little Treatise, have been wrought by me not once onely but often times, and have been shown to many others, so that no body has any reason to doubt hereof, nor need he be sollicitous about any other thing but how wisely to manage, the Operation, and to be diligent about his labours. But if it should so fall out as that a Man should commit an errour or two, which may easily happen, let him not ascribe the errours he commits, to the Art it self, and thereupon to accuse it of falsity, but let him rather inquire into the occasions and reasons of his own errours, and without doubt by such enquiries will he attain his end, and get the hoped for fruit: in which thing, my first and second Century will by an easie Manuduction help him.

These are the things which for the truths sake and to witness it, was I willing to produce. And I do hereby signifie to every one that now my publick Laboratory is at an end, and shall remain shut for time to come, which I was willing every one should know.


[The first] Operation shewing the way of reducing any Lead, or any Vein of Lead by the help of common Salt, [and] by Coals, into Ashes, in the Furnace called Stichofen, that so the Gold and Silver may be extracted with profit.

Take of Lead or a Leaden Vein two parts, and of common Salt one part. The Lead Oar is to be ground in a Mill, and so are they to be commixt, and by little and little thrown with a Shovel upon the Coals in the Furnace, serving to make Ashes, and which has Pipes or Chimnyes fitted thereunto to receive the fume and the ascending Flores. That molten part of Metal and Salt which falls through the Grate is to be again taken up with your Shovel, and cast in upon the Coals untill the whole Metal, or all that metallick Vein shall be turned into Ashes. Then farther, all the burnt matter, is to be freed by divers washings from all the defilements, and the remaining Ashes of the Metal or Metallick Vein, is to be reduced into a Metal in a Furnace which the Germans call Stichofen. These incinerations and reductions are to be so often and so long repeated, untill you find (by making trial with some little piece) that your Lead is now fitted to be handled or wrought on in the Hearths or Furnaces by the Fire of Separation. For then in the Hearths or Tests it is changed into Litharge, whereby it may the more commodiously yield forth the Gold and Silver, which by the Fire and Salt are therein maturated.
