Daughter of Sp. Tarpeius, the governor of the Roman citadel on the Saturnian hill, afterwards called the Capitoline, who was tempted by the gold on the Sabine bracelets and collars to open a gate of the fortress to T. Tatius and his Sabines. As they entered, they threw upon her their shields, and thus crushed her to death. The Tarpeian rock , a part of the Capitoline, was named after her. 2026 Editor's Note: According to Roman legend, Tarpeia was crushed to death by the Sabines' shields rather than receiving the gold jewelry she had been promised. The cliff named after her, the Tarpeian Rock , later became a notorious execution site where traitors and murderers were thrown to their deaths. The cliff was about 25 meters (80 ft) high.
