When I recently reviewed the new biography of Cleopatra, I noted that at least half the book was comprised of endnotes and bibiographies because there just isn't a lot of information about women from ancient history, no matter how powerful they were. So it goes for Livia. The wife of emperor Octavian (Augustus), and related to future emperors Tiberius, Caligula, Claudius, and Nero, only appears in recorded history because of her famous male relatives. It's almost impossible to tell her story without first telling the story of the men in her life, so even in her own biography she's a minor character. I don't know if I learned anything new about her (vs. what I'd already been exposed to in reading separately about the various emperors), but the author is unique in portraying her sympathetically. He interprets her actions as supportive and loyal, whereas she usually comes across as controlling (to put it mildly).
The book gives a lot of detail about the roles women were supposed to adhere to, and the expectations of what was proper behaviour for a female/wife (in summary: bear children, cook, weave, and be supportive, sort of like June Cleaver, but in a toga). As wife of the emperor, Livia's official, public "job" was to be the epitome of a proper, virtuous partner and she filled that position admirably. In private, her close relationship with Augustus -- based on mutual respect -- allowed her to have some influence on his policies and decisions, and the author explores the areas where Livia undoubtedly left her mark. There's a detailed section on Livia's relationship with the Vestals and how she may have influenced Augustus to modify their power and privileges, for example. There are anecdotes about Livia intervening to convince Augustus to show leniency for certain individuals facing punishment (in one case, she assists a wife whose husband is on the proscription list and undoubtedly saves his life). These stories aren't part of any official record, of course, as it would have been unseemly for Livia to be knowingly influencing/suggesting public policy. The author does an excellent job of piecing together clues from a number of sources, from historians of the era to private letters that have survived, and his interpretations are well-supported and logical.
I think one of the most fascinating aspects of Livia's life is that Augustus *adopted* her after his death, via instructions in his will, thus making her both his wife and his daughter. The author offers his own theories as to why Augustus took this step, but admits that any interpretation suffers because nothing is known about Roman adoption rules as they applied to women, so we'll never know what new privileges or rights this may have conferred on Livia, or what Augustus' intentions were when he took this step. There isn't even any record of Livia's reaction to the news. The story of the posthumous adoption can be found in any biography of Augustus, so it unfortunately reinforces the fact that this is a 400+ page book with very little new material about its main character. It's as much a book about the lives of women in the Roman empire and the lives of Augustus and Tiberius as it is about Livia, and that's a disappointment.
I feel comfortable recommending this book to any Roman history buff, and it's an appropriate (albeit, slightly dry) read for someone who wants to learn about the time period from a perspective other than the one offered in typical emperor biographies. On the other hand, if the reader has no prior knowledge of Roman history it could be a bit confusing trying to keep all the players straight because they so often share names. I definitely recommend this for anyone interested in influential women in history, because even though it's light on specific biographical information as compared to a profile of someone from the last century, it's still the only information available and there are very few influential female figures from this time period. Even if you only browse the book in passing, be sure to check out the colour photographs of Livia on coins, jewelry, and in sculpture... some of the images were new to me, and it was nice to see them all in one place.
