A seminal etching from Goya's Los Caprichos series, depicting a sleeping figure surrounded by nocturnal creatures as a critique of irrationality.

This etching is Plate 43 from the series Los Caprichos, a collection of eighty prints published by Francisco Goya in 1799. The composition depicts a sleeping figure slumped over a desk, his head resting on his arms. Behind him, a swarm of nocturnal creatures, including owls, bats, and a lynx, emerge from the shadows. The desk is inscribed with the title: El sueño de la razón produce monstruos.

Goya utilised a combination of etching and aquatint to achieve the atmospheric tonal shifts that define the work. The fine, hatched lines of the etching provide the structure for the figures, while the aquatint creates the grainy, dark background that suggests a space filled with unease. The artist intended this series as a critique of the superstitions and social follies prevalent in Spanish society during the late eighteenth century.

Rather than a simple depiction of a nightmare, the image functions as a commentary on the Enlightenment. Goya suggests that when human reason is abandoned, the mind becomes susceptible to irrationality and chaos. The artist himself appears to be the subject, as he often used his own likeness in his prints. The presence of the lynx, a creature associated with sharp vision, adds a layer of irony to the scene of blindness and slumber. This print remains one of the most recognised images in the history of graphic art, demonstrating Goya's technical mastery and his ability to translate complex philosophical concepts into visual form. The stark contrast between the sleeping man and the active, menacing creatures creates a tension that is characteristic of Goya's later, more introspective work.
