In some cases, it is unclear whether a source using the word "carcer" means "the" Carcer, or imprisonment in some other facility. High-status prisoners, whether Roman or foreign, were typically held in the custody of individual Romans, sometimes at their homes or country estates. The line between being a war captive and a hostage lawfully held by treaty was thin, and conditions of captivity could vary widely, from abject misery and humiliation to relative luxury. As a prisoner of war, Perseus of Macedon was placed in a foul, overcrowded dungeon at Alba Fucens; the son of Tigranes was kept at a praetor's house in Rome, where he could be trotted out as a dinner-party guest. The Tullianum only rarely played a role in these detentions. Captured foreign rulers or generals were paraded in a Roman conqueror's triumph, and on a few occasions the "most prominent, famous, or dastardly" were executed afterward at the Tullianum. These were "strikingly few" in number, and included the Samnite Gaius Pontius, the Gaul Vercingetorix, some "Cilician" pirates, and the Galatian Adiatorix. Jugurtha, king of Numidia, may have been executed at the conclusion of Marius's triumph, or he may have died in prison several days afterward. Most high-status war captives were neither executed nor held for any substantial length of time in the Tullianum.
