Hemelrijk has done an excellent job of collecting the evidence we have on women's education and their role within literary society in the period from the C2nd BCE to 235 CE. She covers the opportunities elite women had to get an education, assesses the aims of that learning, and then examines women who operated as literary patrons and writers.
There's nothing here that is actually new to classicists but a volume like this that collates and presents all the evidence in one place is needed.
Hemelrijk is particularly good at teasing out the contradictions in Roman thought about educated women: on one hand matrons such as Cornelia, mother of the Gracchi, are revered for their educated influence on their sons; yet, at the same time, women such as Sempronia (Sallust) and Clodia Metelli (Pro Caelio) are stigmatised for being better educated than is necessary for a respectable woman.
This is the kind of enabling survey that in itself doesn't change our view of Roman society and women's roles, but it gives us the facts to ask more searching and analytical questions.
