Author(s): Pliny the Elder
Pliny's "Natural History" is an astonishingly ambitious work that ranges from astronomy to art and from geography to zoology. Mingling acute observation with often wild speculation, it offers a fascinating view of the world as it was understood in the first century AD, whether describing the danger of diving for sponges, the first water-clock, or the use of asses' milk to remove wrinkles. Pliny himself died while investigating the volcanic eruption that destroyed Pompeii in AD 79, and the natural curiosity that brought about his death is also very much evident in the "Natural History" - a book that proved highly influential right up until the Renaissance and that his nephew, Pliny the younger, described 'as full of variety as nature itself'.
Gaius Plinius Secundus (23 - 79AD), better known as Pliny the Elder, studied botany and philosophy in Rome before serving in the military. He was later Porcurator in Gallia, whilst continuing to accumulate knowledge on everything from grammar to the history of the German wars. He created the first known encyclopedia.
