Abstract
Due to its concept and methodology, Graingers book on Frontinus is more fact-based fiction than biography. The reader gains an insight into how Frontinus' life and career might have unfolded, taking into account our knowledge of the Roman Empire in his time and the information about him that is confirmed by our sources. The author's assumptions are always plausibly substantiated. However, when reading the book, one learns far more about the Roman Empire, its provinces, its rulers and the political and military conditions in the 1st century AD than about Frontinus. In this respect, this book is very exciting and informative, and it is also pleasant to read.
