Tarpeia. The Roman woman who was said to have given her name ot the Tarpeian Rock, the precipice on the Capitoline hill at Rome from which murderers and traitors were flung to their death. Tarpeia's father was the commander of the Roman citadel when the Romans, under Romulus, were at war with the Sabines. In the usual story Tarpeia accepted a bribe from the Sabine king, Titus Tatius, to let him and his men inside the fortress by night. She asked for her reqard to be what the soldiers wore on their left arms, expecting golden armlets, but instead they repaid her treachery by crushing her to death beneath their shields.
Two variants suggest that Tarpeia was moved, not by greed, but either by love of the Sabine king, Titus Tatius, or by patriotism, since her intention was to disarm the Sabines and deliver them up defenseless to the Romans.

Tarchon. A king of the Etruscans, said to have founded Tarquinii, the chief of the twelve cities of Etruria. Out of hatred for the exiled tyrant MEZENTIUS, Tarchon joined the allies of AENEAS in his war against the Italian tribes.
