The Prophets also, were willing to serve themselves for the most part of their parables, and similitudes, ænigmaes, allegories and figures; where they have covered and hid that which they would not so openly declare, for they have very seldome expressed themselves, as did Esay in his 5 Chapter, where he interprets that the vision of the Lord of Hosts, whereof he there brought a parable, was the people of Israel, and the men of Judah his delectable plant. And in another passage many waters, are many nations. Moreover Ezekiel, 23. having spoken of the two sisters Aholah and Aholibah, he set downe that this was Samaria and that Jerusalem. God by the mouth of Moses, in the 28. of Leviticus, and in the 28. of Deuteronomy, threatned the Israelites, said, if they come to mis-know him, and do not keep well his commandements, that he would make the heaven over their head brasse, and the earth under them iron, which are the two most terrestriall metals, and most hard and rebellious to melt and to handle, opposing them to the durity of this people, as it is there said. I will bruise the pride of your hardnesse, and will make heaven over you as iron, and earth as brasse, your labour shall consume unprofitably, your earth shall not bring forth its seed, nor the tree yeeld any fruit. For metals produce nothing, but are barren; the Poets of their side have used many sorts of Metaphores, and figures, as in the 6. of the Æneid. an iron voice, for a strong and resounding voice, and Hesiod calleth the infernall dog Cerberus, χαλκεόφωνος, a voice of brasse, because it is the most sounding metall; His voice shall sound as brasse, Jer. 16. and Origen upon the 25. of Exod. Brasse is taken for a strong and thundering voice, because of its resounding. Although I should speake with the tongue of Angels, and have not charity in me, I am as sounding brasse, and as a tinkling cymball. Pindarus hath appropriated to Heaven the Epithet of χάλκεος οὐρανὸς Heaven of brasse, in the 10. of the Pythians; because of the firme solidity of the firmament, as the word importeth. Homer doth the same in the 3. of his Odes, calleth it πολύχαλκος, most brasse, as Euripedes and Anaxagoras, make the Sunne a fired iron; for the Greek Poets ordinarily doe put fire and brasse one for another; the same doth Homer in many places, as in the 4. of the Iliads, where Apollo to encourage the Trojans, remonstrates unto them, that the Greeks have not impenetrable bodies, of stone, or of iron, that they should be able to resist blowes of cutting brasse, without hurting them. These are manners of speech, which are not very strange amongst the Prophets, who have thereby figured out the most part of their solutions, under which some mysteries were shadowed; which if men would take altogether raw according to the letter, without allegorizing thereupon, they would find themselves farre from their reckoning, as the Martyr Pamphilus said well in the defence of Origen, speaking of those who to shunne allegories were constrained to stumble at gross impertinencies. They think it of this sort, said he, for that they would not admit of allegories in the holy writ, by reason whereof, as subjecting themselves to the literall sense, they imagine and invent to themselves fine fables, and fictions. And indeed how could a man take according to the letter that of the 33. of Deut. speaking of Aser? Thy shoes shall be iron and brasse, for he would not say that Aser was shod with iron and brasse, but he would understand thereby his force and power, denoted as well by the two metals, as by the shoe; I will extend my shoe against Idumæa, strangers are my subjects; These are all allegories and figures, as also in the 60. of Esay, For brass I bring thee gold, and silver in stead of Iron, brasse for wood, and fire for stones. Marke well how the Prophet observes the relations opposing brasse to gold, and iron to silver; and againe, brasse to wood, and iron to stones; for as gold excelleth silver, and trees stones, it is the same in the metallique order, brasse is more pretious then iron. But all tends to denote that the heavenly mysticall Jerusalem, which is the Church triumphant, so much more excellent then the Jewish Synagogue, which was but a figure thereof. And certainely hee that would looke more narrowly thereinto, the Prophets never spake any thing improperly, even to the least trade or mechanick arts; for in their ravishments they saw things in their reall being, within the Zipheret or supercelestiall Sunne, which is a clear shining looking-glasse, a living source of all Idea’s, as Idea’s are of formes. This is furthermore well to be observed, for the regard of metals, which they associate commonly iron and copper for their affinity; will iron make a covenant with iron from the North? and brasse? for iron is easily changed into copper, by means of vitrioll, by putting them bed upon bed in a descensory with a strong fire of bellowes, so long till the iron grow liquid and melt into copper, having first moistned them with a little vineger, wherein there should be dissolved sal niter, or salt peter, sal alcali, and salt of tartar, with verdigrease. Otherwise put of vitriol in powder, and distill the water in a cornue, that which shall remaine calcined in the bottome, impost it with its water, and therein quench the glowing gads of iron, or filings of iron, you shall find them by little and little reduced into copper: Otherwise yet, dissolve vitrioll in common water, evaporate the water, and calcine the congelation that shall rest in the bottome; dissolve that in the like water, and it will become green, evaporate a part thereof and put the rest in a cave for a night, and you shall see greene flakes. Make them red in the fire, after dissolve them three or four times with distilled vinegar, drying them every time, and the flakes will become red, dissolve them againe in the same vinegar, and therein quench the gads or other iron work, as above said. In briefe, that by the means of vitriol, iron is converted into copper, as we may see in penknifes steeped in inke made of copperas or vitriol.
These flakes here are an entry to a higher work, and of more things for Chirurgery and Medicine. But all these practises (you may say) are long and troublesome and rather chargeable then gainfull, and profitable. Also our intention here, is not to stretch to gaine, this booke is not to get bread, but to penetrate into the secrets of nature: from thence to mount and elevate his spirit to spirituall things, whereto sensible do serve as a stair or as Jacobs ladder; and there are no rarer considerations and observances, then in fire, and metallique transmutations: Copper on the other side, is changed into steele; if it bee true that some Rabbines quote, upon that passage lately alledged out of the 15. of Jeremiah 12. Iron and Brass, the Prophet (say they) calleth Iron mixed with Brasse, Steel, which sheweth (for we must disdain nothing of theirs) that Damake Steel was composed of Iron and Copper, that is to say, of Iron halfe covered in Copper, and softned to restrengthen it the more by means of lead. Whereupon make what Abuhali sets downe in a Book of the nature of things.
Make a little long trench within a barre of iron, and cast thereinto melted lead, then make it evaporate with a strong fire as of a coupelle. Put againe therein new lead four or five times, and the iron will grow soft, which you may afterwards make hard againe quenching it in forge water, to make lancets, and other subtill cutting irons, yea that shall cut other iron, without splinters or gapping. And indeed we have found by experience, that to temper well a harnesse against the shot of harquebuse, we first sweeten it with oils and gums, with wax and the like incerative things; and after we harden them by frequent extinctions, in waters that make it fast againe. John the Grammarian expounding this place of Hesiod, they wrought in brasse, for iron was not yet knowne, was forced to relate the word χάλκος to the people Chalybs in Scythia, who (saith he) first found out the use of iron and steel: the Poet Lucretius in his 5. booke imitates Hesiod in this kinde,
Antient arms were hands and nails,
Stones and fragments of tree boughes,
And flames and fires, were first knowne,
Afterwards the force of Iron and Brasse,
But the use of Brasse, before Iron.
Steel furthermore is made of the most pure and subtiliate iron; for that it participates lesse of the earthinesse, then iron. The artifice of it, is sufficiently knowne, and is common in forges. But to come to that of Damas, you must first resweeten it of its too much bitter tartnesse, and after it is reduced into filings to make it red in a cruset, and quench it many times with oil of Olives, where there hath often times been quenched molten lead, suddenly covering the vessell, for fear lest the oil take flame. There are yet other secret observations, which our intention is not to reveal all; it is enough to have attained to the maxims.
Now for that there is such an affinity between iron, and copper, that they may easily be converted one into the other; the same may likewise be done with lead, and tinne, by means of Sal Armonaick, and of certaine incerative powders of Borax, Salt peter, salt of Tartar, Salalchali, and other the like, which are called Atincars. Panthee in his Voarchadumie, oil of glasse. Quicksilver also, is changed into lead or tinne, according as it is congealed to an imperceptible vapour, either of the one, or of the other, in this manner. Melt lead or tinne in a cruset, then let them a little cool, so long that they may be taken, but yet hot, or with a staffe of a torch, or the like, make a trench therein, wherein you shall put quicksilver which will be suddainly congealed, but bruiseable into powder. Reiterate that two or three times, and make it afterwards boil in the juice of Mercuriale, and will convert it selfe into metall according to the odour of that it was congealed; there is losse therein and that not a little; but yet at least, we may thereby see a possibility of transmutations of metals: In this respect, furthermore of lead, and tinne, there presents a very fair consideration, very uneasie to comprehend, and doth merit, that the cause thereof should bee sought after. We see by experience, that these two metals, each apart, are very soft, and of a tender fusion, yet being mingled they grow hard, and become firm and solid, touching which see what Averroes sets downe in his Book of Vapours. That which doth consolide, and strengthen tinne, is lead; and reciprocally, lead tinne; for the glewish viscosity, which binds their parties, must consist of moisture and drynesse, this being done, there is no conglutination of tinne with tinne, therefore lead is mingled therewith, which is more moist, and with lead, tinne, which is more dry: so that those two mingled together, strengthen one another, better then being separated, and of their mingling, comes to procreate a glewing viscosity, which causeth in them a greater durity then they had, and binds them more firmly, just as sand, and chalke in the composition of Morter, which Albertus also confirmes in his fourth and fifth chapters of Minerals. But wee will put off all these metallique particularities, and their divers transmutations, to our Treatise of Gold and Glasse, upon the 28. of Job, where under gold we wil comprehend all that shal depend on metals: and under glasse, stones, as well naturall, as artificiall; and all vitrifications, and enamels. Here we will take but that which will conduce to our subject, which is to treat of things intelligible, by the sensible: after the imitation of the Prophets, and chiefly metals and fire, whose operation is better known in metals, then in the other composed elements. The Prophets then have set down iron and brasse for a firme resistance. My strength is not the strength of stones, nor is my flesh brasse, Job 6. and in the 18. Psal. Thou hast made my arms as a bow of brasse. Furthermore in the 4. of Micah, I will make thy horne iron, and will make thy hoofs brasse.
