Note 80 — CHEMICAL NAMES OF METALS.
William Johnston translation
In Gorii Thesaurus Gemmarum antiquarum astriferarum, Florent. 1750, 3 vols. fol., I found nothing on this subject. Characters of the moon and of the signs in the zodiac often occur; but no others are to be seen, except in tab. 33, where there is a ring, which has on it the present characters of Mars and Venus. In general the planets are represented by seven small asterisks, or by six and the character of the moon. Besides, the antiquity of this gem cannot be ascertained.
