CHAP. IIII. Of the maner of working, and of moderating, and continuing the fire.
Project Gutenberg EPUB3 edition
Roger Bacon
I Hope ere this time thou hast already found out by the words alreadie spoken (if thou beest not most dull, ignorant, and foolish) the certaine matter of the learned Philosophers blessed stone, whereon Alchimy worketh, whilest we indeuour to perfect the imperfect, and that with things more then perfect. And for that nature hath deliuered vs the imperfect onely with the perfect, it is our part to make the matter (in the former Chapters declared vnto vs) more then perfect by our artificiall labour. And if we know not the maner of working, what is the cause that we do not see howe nature (which of long time hath perfected mettals) doth continually work? Doo wee not see, that in the Mynes through the continuall heate that is in the mountaines thereof, the grosnesse of water is so decocted & thickned, that in continuance of time it becommeth Argent-uiue? And that of the fatnesse of the earth through the same heate and decoction, Sulphur is engendred? And that through the same heate without intermission continued in thẽ, all mettals are ingendred of them according to their puritie and impuritie? and that nature doth by decoction alone perfect or make al mettals, as well perfect as imperfect? O extreame madnesse! what, I pray you, constraines you to seeke to perfect the foresaide things by straunge melancholicall and fantasticall regiments? as one sayth: Wo to you that will ouercome nature, and make mettals more then perfect by a newe regiment, or worke sprung from your owne senselesse braines.
God hath giuen to nature a straite way, to wit, continuall concoction, and you like fooles despise it, or else know it not. Againe, fire and Azot, are sufficient for thee. And in an other place, Heat perfecteth al things. And elsewhere, seeth, seeth, seeth, and be not wearie. And in an other place, let thy fire be gentle, & easie, which being alwayes equall, may continue burning: and let it not encrease, for if it do, thou shalt suffer great losse. And in an other place, Know thou that in one thing, to wit, the stone, by one way, to wit, decoctiõ, and in one vessel the whole mastery is performed. And in an other place, patiently, and continually, and in another place, grinde it seuen times. And in an other place, It is ground with fire. And in an other place, this worke is verie like to the creation of man: for as the Infant in the beginning is nourished with light meates, but the bones beeing strengthened with stronger: so this masterie also, first it must haue an easie fire, whereby wee must alwaies worke in euery essence of decoction. And though we alwayes speake of a gentle fire, yet in truth, we think that in gouerning the worke, the fire must alwayes by little and little bee increased and augmented vnto the end.
