An ancient Roman lead water pipe, an example of the metal’s use in Roman infrastructure.

Clue explainedFact checked

Lead is the metal behind a long-running hypothesis that exposure to it contributed to ancient Rome’s decline. Romans used lead in water pipes, which has prompted questions about how much exposure people experienced. Historians debate how significant lead poisoning was to the empire’s health or political fate, so the clue aptly presents it as a possible cause rather than a settled explanation.
