Francisco Goya painted Saturn Devouring His Son between 1819 and 1823, in oil applied directly to the plaster wall of the dining room of his house outside Madrid. He was in his seventies, deaf for thirty years, recovering from a near-fatal illness, and living alone in a country property called the Quinta del Sordo — the House of the Deaf Man. He did not sign the painting. He did not title it. He did not intend it to be seen. Saturn is one of fourteen pictures Goya painted on
