Second edition in English of the first two Books of this celebrated treatise on mining and metallurgy, the first significant work on the subject in Spanish, and the first work on mining in the Americas. The first Book deals with the generation of metals and things accompanying them, and the second with the extraction of silver by mercury. It also includes the earliest special chapter on petroleum products (Book I, ch. 9) in Peru and elsewhere. The methods of extraction that Barba himself discovered were in large part responsible for the vast wealth that Spain gained from Peru. The book was kept secret in Spain, but when the Earl of Sandwich was Ambassador to Spain, he obtained a copy and translated two of the five books and had them published by Samuel Mearne, the royal bookbinder and publisher. Wing B678 and 682. Another issue (or possibly edition) of the first Book has the title The First Book of the Art of Mettals. Duveen p. 42; Neville I, p. 70 (both with the alternate title). Hoover catalogue 83. Sabin 3254. Norman catalogue 115. No complete English edition of all five Books was done until 1923.
