We give the following brief notes on early works containing some reference to mineralogy, mining, or metallurgy, to indicate the literature available to Agricola and for historical notes bearing upon the subject. References to these works in the footnotes may be most easily consulted through the personal index. GREEK AUTHORS.--Only a very limited Greek literature upon subjects allied to mining or natural science survives. The whole of the material of technical interest could be reproduced on less than twenty of these pages. Those of most importance are: Aristotle (384-322 B.C.), Theophrastus (371-288 B.C.), Diodorus Siculus (1st Century B.C.), Strabo (64 B.C.-25 A.D.), and Dioscorides (1st Century A.D.). Aristotle, apart from occasional mineralogical or metallurgical references in _De Mirabilibus_, is mostly of interest as the author of the Peripatetic theory of the elements and the relation of these to the origin of stones and metals. Agricola was, to a considerable measure, a follower of this school, and their views colour much of his writings. We, however, discuss elsewhere[1] at what point he departed from them. Especially in _De Ortu et Causis_ does he quote largely from Aristotle's _Meteorologica_, _Physica_, and _De Coelo_ on these subjects. There is a spurious work on stones attributed to Aristotle of some interest to mineralogists. It was probably the work of some Arab early in the Middle Ages. Theophrastus, the principal disciple of Aristotle, appears to have written at least two works relating to our subject--one "On Stones", and the other on metals, mining or metallurgy, but the latter is not extant. The work "On Stones" was first printed in Venice in 1498, and the Greek text, together with a fair English translation by Sir John Hill, was published in London in 1746 under the title "Theophrastus on Stones"; the translation is, however, somewhat coloured with Hill's views on mineralogy. The work comprises 120 short paragraphs, and would, if reproduced, cover but about four of these pages. In the first paragraphs are the Peripatetic view of the origin of stones and minerals, and upon the foundation of Aristotle he makes some modifications. The principal interest in Theophrastus' work is the description of minerals; the information given is, however, such as might be possessed by any ordinary workman, and betrays no particular abilities for natural philosophy. He enumerates various exterior characteristics, such as colour, tenacity, hardness, smoothness, density, fusibility, lustre, and transparence, and their quality of reproduction, and then proceeds to describe various substances, but usually omits his enumerated characteristics. Apart from the then known metals and certain "earths" (ochre, marls, clay, etc.), it is possible to identify from his descriptions the following rocks and minerals:--marble, pumice, onyx, gypsum, pyrites, coal, bitumen, amber, azurite, chrysocolla, realgar, orpiment, cinnabar, quartz in various forms, lapis lazuli, emerald, sapphire, diamond, and ruby. Altogether there are some sixteen distinct mineral species. He also describes the touchstone and its uses, the making of white-lead and verdigris, and of quicksilver from cinnabar. Diodorus Siculus was a Greek native of Sicily. His "historical library" consisted of some 40 books, of which parts of 15 are extant. The first print was in Latin, 1472, and in Greek in 1539; the first translation into English was by Thomas Stocker, London, 1568, and later by G. Booth,
