Book excerpt: This book explores the institution of manumission-the freeing of slaves-in ancient Rome from a gendered perspective. Rome was unique among ancient polities in that it bestowed freed slaves with full citizenship, granting them rights nearly equal to those of freeborn individuals. The sexual identities of a female slave and a female citizen were fundamentally incompatible, as the former was principally defined by her sexual availability and the latter by her sexual integrity. Accordingly, those evaluating the manumission process needed to reconcile a woman's experiences as a slave with the expectations and moral rigor required of the female citizen.
