Brennan's book surveys the history of the Roman praetorship, which was one of the most enduring Roman political institutions, occupying the practical center of Roman Republican administrative life for over three centuries. The study addresses political, social, military and legal history, as well as Roman religion. Volume I begins with a survey of Roman (and modern) views on the development of legitimate power--from the kings, through the early chief magistrates, and down through the creation and early years of the praetorship. Volume II discusses how the introduction in 122 of C. Gracchus' provincia repetundarum pushed the old city-state system to its functional limits. The list of topics is enormous, the accumulated detailed scholarship stunning. There is no doubt that Brennan's massive study is a necessary addition to the library of every professional historian of Rome and will be employed by scholars as the standard work on the praetorship for decades to come.
