The Elder Pliny's Natural History provides a wide-ranging account of human achievement in the arts and sciences in the first century AD. This book re-examines Pliny's work for the first time since the 1920s. Modern experiments, simulating the techniques described by Pliny, and an in-depth study of his development of a technical language, confirm his unique contribution to our knowledge of science in early imperial Rome.
