Originally intended as a frontispiece, El sueño de la razon produce monstruos is number 43 in the series Los Caprichos (1799) by Francisco José de Goya y Lucientes. Also one of his roughly 40 self-portraits, this ambiguous picture shows a seated male figure with his ankles crossed leaning over to his right as he rests his elbows and head on a desk. The male figure wears an ankle-length coat, breeches, stockings, and shoes. His hair is long, his face invisible. On top of the desk, under his right elbow, we see a paintbrush or writing instrument. The side of the desk, in the lower left corner, bears the title of the work. On the floor to the man's right crouches a lynx. Owls with huge wings and expressive eyes surround him. The owl on his right holds out a paintbrush. A cat with watchful eyes perches behind his back. Above the human figure large bats are flying; the largest one at the top right has a goat-like head.
