In Greek mythology, the god Prometheus surreptitiously gave the gift of fire to humanity, thus sparking civilization and upsetting his fellow gods for altering the power differential between themselves and we lowly mortals. As punishment, he was chained to a rock for eternity. An eagle ate his liver, which continuously regenerated, thus sparing him from death but not agony.
The French makers of these liver pills from the 1930s imply that Prometheus would have benefited from their product. It's a rather brutal celebrity endorsement and classicist Edith Hall of Durham University, who shares this image on Twitter, says that she can think of a better advertising strategy.
