Tarpeian Rock

The Tarpeian Rock (/tɑːrˈpiːən/; Latin: Rupes Tarpeia or Saxum Tarpeium; Italian: Rupe Tarpea) is a steep cliff of the southern summit of the Capitoline Hill, overlooking the Roman Forum in Ancient Rome. It was used during the Roman Republic as an execution site. Murderers, traitors, perjurors, and larcenous slaves, if convicted by the quaestores parricidii, were flung from the cliff to their deaths. The cliff was about 25 meters (80 ft) high. There seems to be a belief that similar punishments were inflicted on the disabled and mentally ill but there are no reliable sources for that.

According to early Roman histories, when the Sabine ruler Titus Tatius attacked Rome after the Rape of the Sabines (8th century BC), the Vestal Virgin Tarpeia, daughter of Spurius Tarpeius, governor of the citadel on the Capitoline Hill, betrayed the Romans by opening the city gates for Titus Tatius in return for "what the Sabines bore on their arms" (golden bracelets and bejeweled rings). In Book 1 of Livy’s Ab Urbe Condita, the Sabines "having been accepted into the citadel, [the Sabines] killed her, having been overwhelmed by weapons, and "scuta congesta", meaning, "[they] heaped up shields [on her]". The Sabines crushed her to death with their shields, and her body was buried in the rock that now bears her name. Regardless of whether or not Tarpeia was buried in the rock itself, it is significant that the rock was named for her deceit.
