About the Display: Promethium is a radioactive element, therefore, the box contains items that represent the element and the Greek god Prometheus, for whom the element is named after. Prometheus was known to be an intelligent trickster who stole fire from Zeus to give to mortals, resulting in his subsequent punishment. He was punished by remaining in chains as an eagle ate his liver, only for the liver to grow back and be eaten again the following day.
