I am quite fond of speculation, and allusion, and I can even tolerate quite a lot of repetition (for good didactic purpose), but I found this book gave me too much of all three. Now, having said that, I quite concede that Livia is not the easiest of subjects - the material is thin, and comes in patches, which poses a terrible difficulty to presenting a balanced biography covering the whole life. Moreover any biographer pretty much has to assume that the reader is going to come to the book with the tabloid version which Graves permissibly took from a lot of fairly hostile sources and immortalised via I Claudius (with able help from the marvellous Sian Phillips in the TV version).
So what to do? Dennison is not helped by the fact that one good approach has already been taken by Barrett (
Livia: First Lady of Imperial Rome) who essentially has "written against" Graves. What he ends up doing instead is producing an inquiry which seems to have the aim of combining accessible scene setting with allowing the reader to take their own view. This sounds fine, but somehow (at least for me) it really doesn't work, though I find it hard to put my finger on why. I think it may be because the spoon feeding of the background, combined with the speculation, steer us down this course or that, without coming to any conclusion.
To illustrate what I mean: (i) Quotations from various Roman authors are taken again and again to scene set the life of a Roman family. These are good and well used - but then the quotation (which will have no reference actually to Livia) will be used to invite us to picture her at this that or the other stage of her life, based on this speculative basis. (ii) There is too much of the "How must she have felt ..?" stuff which is the hallmark of what one might term the romantic biographer (let's face it, we are all capable of asking that question for ourselves at striking points in a factual story). There is also a good deal of the "Was she really doing X or Y" - posing the Graves allegations without weighing the evidence.
I also felt that while all this speculation was going on there was insufficent control of certain building blocks of a really good biography: consistency (going from decribing the fecundity of the Claudius Pulchers scant pages before stating as a fact that noble Romans never had many children), sound factual basis (Atticus was NOT Cicero's "secretary" - his mother was a Caecilia Metella for heavens sake; Tiro was Cicero's secretary), and disciplined structure (enough dotting forward and back in time to leave one's head whirling).
So overall, while I wanted to like the book, and found the use of allusions from Ovid and Horace etc clever and pleasant, and I even quite like what I think is being attempted, I found it more annoying than enjoyable.
