Los Disparates (Follies or Irrationalities) was Goya’s last series of etchings and remained unpublished in his lifetime. As with his other late etchings, they were etched on English copper plates. They were packed away in Goya’s Spanish home when Goya left for France in 1824. 18 of the 22 extant plates were first issued in 1864 under the title Los Proverbios (Proverbs). Some of the plates can be seen as relating to Spanish proverbs, while the current title of Los Disparates follows the discovery of working proofs with titles, in Goya’s own hand, most of which included the word Disparata (Folly) and a characteristic, such as the Disparate de Carnabal (Carnival Folly) offered here. The plates were etched in Spain probably between 1815 and 1819.
