This book is about Sosipatra of Pergamum, a female philosopher who lived in the fourth century CE, a time when the Roman world was undergoing remarkable political, cultural (in particular religious), and even economic changes. Born into a wealthy family near Ephesus, Sosipatra played a critical role in exemplifying the kind of philosophical life that would best allow for the continued existence of Iamblichan Platonism in a Christianized world where the more problematic aspects of theurgy were downplayed or effaced in favor of an approach that maintained a clear understanding of cosmic hierarchy, despite believing humans can participate in divinity in a number of ways. She also acted as a point of critical contrast to the Christian ideal of the virginal or celibate female ascetic, as she married and had children. She ultimately led her own philosophy school in Pergamum.
