Pliny the Elder

Gaius Plinius Secundus (AD 23/24 - 79), known in English as Pliny the Elder ( ), was a Roman author, naturalist, and naval and army commander of the early Roman Empire, and a friend of the emperor Vespasian. He wrote the encyclopedic (''Natural History''), a comprehensive thirty-seven-volume work covering a vast array of topics on human knowledge and the natural world, which became an editorial model for encyclopedias. He spent most of his spare time studying, writing, and investigating natural and geographic phenomena in the field.

Among Pliny's greatest works was the twenty-volume ''Bella Germaniae'' ("The History of the German Wars"), which is no longer extant. ''Bella Germaniae'', which began where Aufidius Bassus' ''Libri Belli Germanici'' ("The War with the Germans") left off, was used as a source by other prominent Roman historians, including Plutarch, Tacitus, and Suetonius. Tacitus may have used ''Bella Germaniae'' as the primary source for his work, ''De origine et situ Germanorum'' ("On the Origin and Situation of the Germans").

Pliny the Elder died in AD 79 in Stabiae while attempting the rescue of a friend and her family from the eruption of Mount Vesuvius. Provided by Wikipedia
