This painting by Goya (of Saturn Eating his Son fame) came from a group of smaller paintings that Goya executed - because the topic interested him rather than commissioned. Both as a visual narrative and as a painting per se it is influenced by Goya’s keen interest in the grim fate that befell many people during his lifetime. The painting shows monks, soldiers, and convicted prisoners in white robes, probably on their way to the site of their execution.
