[1474] I am of opinion that this Latin name for cobalt was first used by Agricola.

[1487] Mathesius, in his tenth Sermon, p. 501, where he speaks of the cadmia fossilis, says, “Ye miners call it kobolt; the Germans call the black devil, and the old devil’s whores and hags, old and black kobel, which by their witchcraft do injury to people and to their cattle.”... Whether the devil, therefore, and his hags gave this name to cobalt, or cobalt gave its name to witches, it is a poisonous and noxious metal. Agricola, De Animantibus Subterraneis, says, at the end, “Dæmones, quos Germanorum alii, aut etiam Græci, vocant cobalos, quod hominum sunt imitatores.” Bochart, in his Canaan, i. 18, p. 484, gives a Hebrew derivation of κόβαλος. It appears to be the same as covalus and gobelinus, the latter of which was used by Ordericus Vitalis in the eleventh century as the name of a spirit or phantom. See Menage, Diction. Etymol. i. 681.

[1489] Melzer’s Berglauftige Beschreibung der Stadt Schneeberg, 1684, 4to, p. 405. The same account is given in his Historia Schneebergensis, 1716, 4to. In these works one may see the dispositions made from time to time by the electors of Saxony, to support this highly profitable manufacture. The latest information on this subject is to be found in Hoffmann’s Abhandlung über die Eisenhütten, Hof. 1785, 4to.

[1492] I say, in the beginning of the sixteenth century, on the authority of the following information in Melzer, which seems not to have been noticed by others:—“Peter Weidenhammer, a Franconian, came hither poor; but by means of a colour he procured from pounded bismuth, and of which he exported many quintals to Venice, at the rate of twenty-five dollars per quintal, he soon acquired great riches, and built a beautiful house in the market-place. His name is inscribed in the lower window of the chancel of the great church, with the date 1520.” At that period a great deal of this paint was prepared at Venice, and it may therefore be easily comprehended how Vannuccio could be so early acquainted with zaffera.
[1493] How early manufactories for blue paint were erected beyond the boundaries of Saxony and Bohemia I do not know, as I have found no information on that subject. We are however told by Calvor, in Beschreibung des Maschinenwesens am Oberharze, ii. p. 202, that a person was engaged to superintend the blue-paint-manufactory at St. Andreasberg in the year 1698.
