Los Caprichos is a set of 80 prints in aquatint and etching created by the Spanish artist Francisco Goya in 1797–1798 and published as an album in 1799. The prints were an artistic experiment: a medium for Goya's satirizing Spanish society at the end of the 18th century, particularly the nobility and the clergy. Goya in his plates humorously and mercilessly criticized society while aspiring to more just laws and a new educational system. Closely associated with the Enlightenment, the criticisms are far-ranging and acidic. The images expose the predominance of superstition, religious fanaticism, the Inquisition, religious orders, the ignorance and inabilities of the various members of the ruling class, pedagogical shortcomings, marital mistakes, and the decline of rationality.
