Extremely well-researched book. Focusing mostly on debates over the form of certain institutions, it delves too much for my taste into legal minutiae important more to the scholar than the general reader. Despite this, presentation of the contrasting interpretations of the different institutions - especially with comparison to the lights of Polybius - were interesting and valuable to me. Please note that I put this book down after completion of the chapter on the Senate, for the reasons stated above.
