WIRE-DRAWING.
It is highly probable that in early periods metals were beat with a hammer to thin plates or leaves, which were afterwards divided into small slips by means of a pair of scissors, or some other instrument; and that these slips were by a hammer and file then rounded, so as to form threads or wire. This conjecture seems to be confirmed by the oldest information respecting work of this kind. When the sacerdotal dress of Aaron was prepared, the gold was beaten and cut to threads, so that it could be interwoven in cloth[1243]. We are told also that Vulcan, desirous to expose Mars and Venus, while engaged in their illicit amour, repaired to his forge, and formed on his anvil, with hammers and files, a net so fine that it could be perceived by no one, not even by the gods themselves, for it was as delicate as a spider’s web[1244]. These fine threads therefore were at that time first beat upon the anvil, and afterwards rounded by a file, but were not drawn out like our wire. I do not remember to have found a single passage in ancient authors where mention is made of metal prepared by being wire-drawn. The æs ductile of Pliny was so called because it was malleable, and could be beat into thin leaves; and he says “tenuatur in laminas[1245].” In my opinion, works made with threads of metal occur too seldom in the writings of the ancients, to allow us to suppose that they were acquainted with that easy and cheap method of forming these threads by wire-drawing. Wire-work is rarely mentioned, and wherever it is spoken of, it appears to have been prepared on the anvil.
Such threads of the dearest and most malleable metal, gold, seem to have been early employed for ornamenting different articles of dress, but certainly not in so ingenious and beautiful a manner as in modern times. It is probable that slips of gold were sewed upon clothes, and particularly on the seams, as is still practised with lace; and perhaps gold stars and other figures cut from thin plates of gold were applied to dresses in the same manner, as is the case at present with spangles, and perhaps they were only affixed to them with paste. People however soon began to weave or knit dresses entirely of gold threads, without the addition of any other materials; at least such seems to be the account given by Pliny[1246]. Of this kind was the mantle taken from the statue of Jupiter by the tyrant Dionysius[1247], and the tunic of Heliogabalus mentioned by Lampridius[1248]. These consisted of real drap d’or, but the moderns give that name to cloth, the threads of which are silk wound round with silver wire flattened and gilded.
The invention of interweaving such massy gold threads in cloth is by Pliny ascribed to king Attalus; but I consider it to be much older, though I have found no certain proofs to support this opinion. I conjecture that the cloth of Attalus, so much extolled on account of its magnificence, was embroidered with the needle; for in the passage where embroidery is mentioned by Pliny for the first time, he speaks of its being invented by the Phrygians; he then mentions the cloth of Attalus; and immediately after the Babylonian, which, as is proved by several expressions in ancient authors, was certainly embroidered with the needle[1249]. If I am not mistaken, Attalus first caused woollen cloth to be embroidered (not interwoven) with threads of gold; and the doubt that Pliny assigns too late a period to the interweaving cloth with threads of gold is entirely removed. It appears that in the third century gold was interwoven with linen, that linen was embroidered with gold threads, or that gold threads were sewed upon linen, which the emperor Alexander Severus considered as folly; because by these means the linen was rendered stiff, cumbersome and inconvenient[1250].
It was not till a much later period that silver began to be formed into threads by a like process, and to be interwoven in cloth. Salmasius and Goguet have already remarked that no mention of silver stuffs is to be found in the works of the ancients; for the passages which might be quoted from Homer speak only, without doubt, of white garments[1251]. Pliny certainly would not have omitted this manner of preparing silver, had it been usual in his time; especially as he treats so expressly of that metal, and its being employed for ornaments, and speaks of gold threads and embroidering with gold. Vopiscus, however, seems to afford us an indubitable proof that silver thread was not known in the time of the emperor Aurelian[1252]. This author informs us that the emperor was desirous of entirely abolishing the use of gold for gilding and weaving, because, though there was more gold than silver, the former had become scarcer, as a great deal of it was lost by being applied to the above purposes, whereas every thing that was silver continued so[1253]; but it has been fully proved by Salmasius that silver threads were interwoven in cloth in the time of the last Greek emperors[1254].
The period when attempts were first made to draw into threads metal cut or beat into small slips, by forcing them through holes in a steel plate placed perpendicularly on a table, I cannot determine. In the time of Charlemagne this process was not known in Italy; for however unintelligible may be the directions given in Muratori[1255], “de fila aurea facere, de petalis auri et argenti,” we learn from them that these articles were formed only by the hammer. It is extremely probable that the first experiments in wire-drawing were made upon the most ductile metals, and that the drawing of brass and iron to wire is of later date. It is likewise certain that the metal was at first drawn by the hand of the workman; in the same manner as wire is drawn by our pin-makers when they are desirous of rendering it finer. They wind it off from one cylinder upon another, by which means it is forced through the holes of the drawing-iron; and this process agrees perfectly with the description of Vanuccio[1256] and Garzoni[1257], as well as with the figures in the German translation of the latter.
As long as the work was performed by the hammer, the artists at Nuremberg were called wire-smiths; but after the invention of the drawing-iron they were called wire-drawers and wire-millers. Both these appellations occur in the history of Augsburg so early as the year 1351; and in that of Nuremberg in 1360[1258]; so that, according to the best information I have been able to obtain, I must class the invention of the drawing-iron, or proper wire-drawing, among those of the fourteenth century.
