The Epilogue
I doubt not but many Men considering the great good that may be effected by the benefit of Nitre, will be desirous of knowing how they may attain it in great quantity, that so they may not be forced to buy it at a dear rate; which certainly would be a great help not to a few who labour in the fire, and I could wish from my Soul, that all honest and pious Chymists might be able to recover some compensation for the Coals they have consumed without fruit. But seeing that I have made mention of the production or preparation of Nitre, in a peculiar Treatise entituled, The Prosperity of Germany; it is needless here to repeat it. But this I will say by way of prediction, that Nitre, being thoroughly known by my Writings, true Alchymy, or the Transmutation of the imperfect Metals into better, will in a short time be as common, as it was in Egypt long since in the time of the Emperour Dioclesian, who could not overcome or subdue the Egyptians, until he had by many Cruelties extorted their Books from them, which he burnt, and so brought them under the yoke of servitude. NB. That it is no wonder that the Transmutation of Metals should have been so common with the Egyptians only, seeing that Nitre is found in all places of the Land of Egypt, and the famous River Nile is impregnated with Nitre, which only by its overflowing (which it doth twice in a year) so fateneth the whole Country, that it is made very rich and fruitful in all things without dung; for the Nile aboundeth with Nitre, as the Sea doth with common Salt. For at certain times of the overflowing, viz. in the beginning, the inhabitants are wont to dig deep Pits, that they may remain full of the water, which being afterwards dried up by the Sun, Nitre is very Copiously prepared, as common Salt is made in Spain, and other hot Regions. This therefore I was willing to discover for the information of the Reader; if he be wise, and God be propitious to him, he will believe that I have said enough; but if not, an Explication ten times clearer will not help him. Therefore let it suffice, that what is here desired, shall be had in those Treatises which are entituled, The Prosperity of Germany, whereby a man filled with the Love of God, will be greatly delighted.
