Gaius Plinius Secundus, Roman admiral and encyclopedist. His thirty-seven-book Natural History gathers what some hundred authors had written of the heavens, the earth, animals, plants, drugs, and metals, with much hearsay and many marvels. He died in the eruption of Vesuvius, having sailed across the bay to observe it and help those trapped there.
