The Mamertine Prison (Italian Carcere Mamertino), in antiquity the Tullianum, was a prison (carcer) located in the Comitium in ancient Rome. It was located on the northeastern slope of the Capitoline Hill, facing the Curia and the imperial fora of Nerva, Vespasian, and Augustus. Located between it and the Tabularium (record house) was a flight of stairs leading to the Arx of the Capitoline known as the Gemonian stairs.
Name and origin
The origins of the prison's names are uncertain. The traditional derivation of "Tullianum" is from the name of one of the Roman kings Tullus Hostilius or Servius Tullius (the latter is found in Livy, Varro, and also Sallust); there is an alternative theory that it is from the archaic Latin tullius "a jet of water", in reference to the cistern. The name "Mamertine" is medieval in origin, and may be a reference to a nearby temple of Mars.
According to tradition, the prison was constructed around 640-616 BC, by Ancus Marcius. It was originally created as a cistern for a spring in the floor of the second lower level. Prisoners were lowered through an opening into the lower dungeon.
Imprisonment was not a sentence under Roman statutory law, though detention is mentioned in the Twelve Tables and throughout the Digest. "Detention," however, includes debt bondage in the early Republic; the wearing of chains (vincula publica), mainly for slaves; and during the Imperial era a sentence of hard labor, as at the mills, mines or quarries. Slaves or lower-status citizens sentenced to hard labor were held in prison camps.
Incarceration (publica custodia) in facilities such as the Tullianum was intended to be a temporary measure prior to trial or execution; abuses of this principle occurred but were officially censured. Located near the law courts, the Tullianum was used as a jail or holding cell for short periods before executions and as a site for executions. In 63 BC, certain co-conspirators of Catiline, including Publius Cornelius Lentulus Sura, were held briefly in the Tullianum and executed there for their alleged plot to overthrow the government. In this case, the executions were conducted hastily, without due process of appeal, during the consulship of Cicero, who was later exiled for his actions. Sejanus was held in the Tullianum before his baroque execution, which involved the Gemonian stairs, and the conflicting accounts of the end of Pleminius include a timely death in jail during trial. Some Gracchan sympathizers ended up in the Carcer, where the unfortunate haruspex Herennius Siculus hit his head on an architrave and died before he could be executed.
There is no evidence that the Tullianum was used for long-term incarceration, and the lowest dungeon was unsuited for the purpose; the level above, however, in theory might have been. In general, long-term incarceration was more widely practiced in the later Empire, and from the 4th century, under Christian rule, Roman laws and occasional personal intervention on the part of an emperor indicate a growing need to crack down on abuses such as filthy conditions and torture.
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.
It is not known when the prison went out of service permanently, but the site has been used for Christian worship since medieval times, and is currently occupied by two superimposed churches: S. Giuseppe dei Falegnami (upper) and S. Pietro in Carcere (lower). The Cross on the altar in the lower chapel is upside down, since according to tradition Saint Peter was crucified that way. A tradition has long held that St. Peter was imprisoned at the Tullianum, and that the spring in the bottom of the pit came into existence miraculously to enable him to conduct baptisms, but the Catholic Encyclopedia points out that the spring had existed long before, and that there is no "reliable evidence" of St. Peter's imprisonment there.

- The Roman triumph emphasized splendor and the nobility and ethnicity of captives, sometimes in chains, sometimes not: "The successful general accrues little glory for representing his victory as won by thrashing a mangy band of feeble and unimpressive suppliants. The best conquests are won against tough and worthy opponents, not against those who look as though they could not have put up much of a fight in the first place."
