I've had an interest in Roman History from an early age, due to living near a major Romano-British complex. I was therefore interested to see what this book would provide in terms of information. It was written back in the late 19th century, and therefore contains a number of items that have been superceded by more modern historians, but it is still quite an enjoyable read.
About three quarters of the book is a linear description of the history of Rome from about 400 B.C. to the fall of the empire in 476 A.D. This has some useful explanations of the politics, and affiliations between the main characters. It is also useful that the author makes extensive use of capitals throughout to highlight the names of people and places as they first appear within the narrative.
The last part of the book also contains some further information; a timeline, details of key sources from Roman writers, more detailed information on laws, customs, politics and strategy. There are also some example questions from examinations papers used by the main "Ivy League" colleges from the USA of the time of the writing of the book. Sadly, I don't think that they use these any more!
