"Louis Arrives in Hell"
In classical mythology, the journey to Hell involved crossing the river Styx. Revolutionary cartoonists often invoked this image when describing the fate of their enemies. This is no exception. See the boat on the left with the dog, Cerberus, who was the guardian of the gates of the underworld. Arriving here is the headless Louis, greeted by other prior monarchs. In the right corner is a glade, showing a contrasting world in which people dance happily around the liberty pole.
