Saturn or Saturn Devouring His Son is a 1636 painting by the Flemish artist Peter Paul Rubens, now in the Museo del Prado.
It was commissioned for the Torre de la Parada by Philip IV of Spain and shows the influence of Michelangelo on Rubens, which he had picked up on his journey to Italy. The three stars at the top of the painting represent the planet Saturn as described by Galileo a few years before its painting.
