Before Jeremy Bentham died, he left strict instructions for his remains to become the first “auto-icon,” a straw-stuffed skeleton statue that would take the place of a tomb. Auto-icons, he explained, would save lots of cemetery space, provide scientists with a ceaseless supply of cadavers to study, and also “diminish the horrors of death.” Bentham did become the first auto-icon, but his mummified head was so frightening that it was replaced with a fake one. So where did his real head end up?

Some were lost, others were found, and one—Saint Francis Xavier’s pinky toe—was (purportedly) bitten off by a zealous fan. The toe was never swallowed, but the same can’t be said for King Louis XIV’s shriveled heart: a well-respected British geologist is said to have gobbled it down without a second thought.
