Archaeologists picking through latrines, sewers, cesspits and trash dumps at Pompeii and Herculaneum have flushed out tantalizing clues to what appears to be a varied diet in those ancient Roman cities destroyed in 79 A.D. by the eruption of Vesuvius. Much of what the inhabitants of those doomed towns didn’t digest or left on their plates became traces lining toilet pipes, remnants in centuries-long buildup in cesspits, or throwaway in dumps. At a three-day conference ending Friday in Rome, archaeologists discussed their discoveries, including gnawed-on fish bones, goose eggshells from meals of the elite and carbonized nibbles baked perhaps as offerings for deities.
