This is another good brochure of the dynamic Historical Institute of the University of Potosí (see HAHR, Feb., 1961). The monograph is based on excellent primary sources. It is a valuable new contribution to the much needed Bolivian social history. Chacón shows that even during the very decline of Potosí (“su más completa decadencia”) there was a healthy creative spirit among the mestizo and criollo artisans. It also shows that independence did not bring a radical break in colonial artistic forms—there was hardly any change. The young Chacón has written a truly splendid monograph. He has also resurrected from complete oblivion a great number of able artistic artisans.
