The name zinc occurs first in Paracelsus. He expressly calls it a distinct metal, the nature of which was not sufficiently known; which could be cast, but was not malleable, and which was produced only in Carinthia. Was he then unacquainted with the zinc of Goslar, which was known at an earlier period to Albertus Magnus[100]? George Agricola, who wrote about the year 1550, speaks however of the Goslar zinc, but he calls it _liquor candidus_, and in German _conterfey_[101]. Mathesius, who published his sermons in 1562, says, “at Freyberg there is red and white zinc.” Perhaps he did not mean the metal, but minerals that contained zinc. George Fabricius, who died in 1571, conjectures that _stibium_ is what the miners call _cincum_, which can be melted, but not hammered. It is seen by these imperfect accounts that this metal must have been scarce, even in the middle of the sixteenth century, and that it was not in the collection of Agricola, which was considerable for that period. Libavius, who died in 1616, mentions it several times, but he regrets, in one of his letters, that he had not been able to procure any of it[102]. Was this owing to the prohibition of duke Julius, by which it was forbidden to be sold? This prohibition is quoted by Pott from Jungii Mineralogia, with which I am unacquainted; but as Pott has already, by his unintelligible quotations, made me spend many hours to no purpose, I shall not waste more in searching for it. The prohibition alluded to is mentioned neither by Rehtmeier nor by any other author. The foolish taste for alchemy, which prevailed then at the duke’s court, makes it not altogether improbable that one was issued[103]; and if that was really the case, it was occasioned not so much by any dread of this metal being misused, as Pott thinks, but by the high hopes which were entertained of its utility in making gold. The first accurate and certain account of the method of procuring zinc at Goslar, is, as far as I know, given by Lœhneyss, in 1617, though he considers it to be the same as bismuth[104]. Joh. Schrœder of Westphalia, who died in 1664, calls it _marcasita pallida_.
