CHAP. VI.
The opinion of diverse learned men touching the folly of Alchy∣mistry.
* 1.1ALbert in his book of Minerals reporteth, that Avicenna treating of Al∣chymistry, saith; Let the dealers in Alchymistry understand, that the very nature and kinde of things cannot be changed, but rather made by art to resemble the same in shew and likenesse; so that they are not the very things indeed, but seem so to be in appearance; as castles and towers do seem to be built in the clouds, whereas the representations there shewed, are nothing else but the resemblance of certain objects below, caused in some bright and clear cloud, when the aire is void of thicknesse and grossnesse. A sufficient proofe hereof may be the looking glasse. And we see (saith he) that yellow or orrenge colour laid upon red, seemeth to be gold.* 1.2 Francis Petrarch treating of the same matter in forme of a dia∣logue, introduceth a disciple of his, who fansied the foresaid fond professi∣on and practice, saying; I hope for prosperous successe in Alchymistry. Pe∣trach answereth him; It is a wonder from whence that hope should spring, sith the fruit thereof did never yet fall to thy lot, nor yet at any time chance to any other; as the report commonly goeth, that many rich men, by this vanity and madnesse have been brought to beggery, whiles they have wearied themselves therewith, weakned their bodies, and wa∣sted their wealth in trying the means to make gold ingender gold. I hope for gold according to the workmans promise, saith the disciple. He that hath promised the gold, will run away with thy gold, and thou ne∣ver the wiser, saith Petrarch. He promiseth me great good, saith the disciple. He will first serve his own turn, and relieve his private pover∣ty, saith Petrarch; for Alchymisters are a beggerly kind of people, who though they confesse themselves bare and needy, yet will they make others rich and wealthy; as though others poverty did more molest and pity them then their owne. These be the words of Petrarch, a man of great learning and no lesse experience; who as in his time he saw the frau∣dulent fetches of this compassing craft; so hath there been no age, since the same hath been broached, wherein fome few wise men have not smelt out the evill meaning of these shifting merchants,* 1.3 and bewrayed them to the world.
