Hundreds of foreign hostages were detained among the Romans as the empire grew in the Republic and early Principate. As prominent figures at the center of diplomacy and as ?exotic? representatives, or symbols, of the outside world, they drew considerable attention in Roman literature and other artistic media. Our sources discuss hostages in terms of the geopolitics that motivated their detention, as well as in accordance with other structures of power. Hostages, thus, could be located in a social hierarchy, in a family network, in a cultural continuum, or in a sexual role. In these schemes, an individual Roman, or Rome in general, becomes not just a conqueror, but also a patron, father, teacher, or generically masculine. By focusing on the characterizations of hostages in Roman culture, we witness Roman attitudes toward ethnicity and imperial power.
