"The first edition [of Los Capricos ] is usually said to have been issued in 1797, but this is an error based upon the discovery of a sketch for the title-page dated in that year. Isolated proofs were to be seen in 1796, but the whole work was not ready until 1798 or 1799. Goya was slowly printing the two hundred copies in an attic workroom he had specially engaged for the purpose at the corner of the Calle de San Bernardino, but for some while the job was completely set aside. He drew up a draft prospectus which was never published.. .This draft belonged to Valentin Carderera."
