APPENDIX A. 



AGRICOLA'S WORKS. 



EORGIUS AGRICOLA was not only the author of 

 works on Mining and allied subjects, usually asso- 

 ciated with his name, but he also interested himself 

 to some extent in political and religious subjects. 

 For convenience in discussion we may, therefore, 

 divide his writings on the broad lines of (i) works on 

 mining, geology, mineralogy, and allied subjects ; (2) 

 works on other subjects, medical, religious, critical, 

 political, and historical. In respect especially to the 

 first division, and partially with regard to the others, we find three principal 

 cases : (a) Works which can be authenticated in European libraries to-day ; 

 (6) references to editions of these in bibliographies, catalogues, etc., which we 

 have been unable to authenticate ; and (c) references to works either un- 

 published or lost. The following are the short titles of all of the published 

 works which we have been able to find on the subjects allied to mining, 

 arranged according to their present importance : De Re Metallica, first 

 edition, 1556 ; De Natura Fossilium, first edition, 1546 ; De Ortu et Causis 

 Subterraneorum, first edition, 1546 ; Bermannus, first edition, 1530 ; Rerum 

 Metatticarum Interpretatio, first edition, 1546 ; De Mensuris et Ponderibus, 

 first edition, 1533 ; De Precio Metallorum et Monetis, first edition, 1550 ; De 

 Veteribus et Novis Metallis, first edition, 1546 ; De Natura eorum quae Effluunt 

 ex Terra, first edition, 1546 ; De Animantibus Subterraneis, first edition, 1549. 



Of the " lost " or unpublished works, on which there is some evidence, 

 the following are the most important : De Metallicis et Machinis, De Ortu 

 Metallorum Defensio ad Jacobum Scheckium, De Jure et Legibus Metallicis, 

 De Varia Temperie sive Constitutione Aeris, De Terrae Motu, and Commen- 

 tariorum, Libri VI. 



The known published works upon other subjects are as follows : Latin 

 Grammar, first edition, 1520 ; Two Religious Tracts, first edition, 1522; 

 Galen (Joint Revision of Greek Text), first edition, 1525 ; De Bella adversus 

 Turcam, first edition, 1528 ; De Peste, first edition, 1554. 



The lost or partially completed works on subjects unrelated to mining, 

 of which some trace has been found, are : De Medicatis Fontibus, De Putre- 

 dine solidas paries, etc., Castigationes in Hippocratem, Typographia Mysnae 

 et Toringiae, De Traditionibus Apostolicis, Oratio de rebus gestis Ernesti et 

 Alberti, Ducum Saxoniae. 



REVIEW OF PRINCIPAL WORKS. 



Before proceeding with the bibliographical detail, we consider it desirable 

 to review briefly the most important of the author's works on subjects related 

 to mining.
