Valens has a poor reputation as a Roman Emperor. Given that he presided over the disaster at Adrianople, this is understandable. This book goes some way to suggesting that although he could never be classed as a great emperor, he was a competent man who momentarily lost control.
The book starts at the last days of Julian’s reign and runs through the rule of Valentian I and his brother Valens. Throughout most of the book Hughes takes a methodical, almost annalistic, approach. The military campaigns and major events of each year are briefly described. This is quite a dry style, but it does pay off when the author begins to draw conclusions later in the book. The battle of Adrianople, and the campaign around it, is covered in more detail in the last few chapters.
