In his episode Aude Doody reads from the Introduction to Pliny’s Encyclopedia: The Reception of the Natural History, published by Cambridge University Press. The Elder Pliny's Natural History is one of the largest and most extraordinary works to survive from antiquity. It has often been referred to as an encyclopedia, usually without full awareness of what such a characterisation implies. In this book, Dr Doody examines this concept and its applicability to the work, paying far more attention than ever before to the varying ways in which it has been read during the last two thousand years, especially by Francis Bacon and Denis Diderot. This book makes a major contribution not just to the study of the Elder Pliny but to our understanding of the cultural processes of ordering knowledge widespread in the Roman Empire and to the reception of classical literature and ideas.
