In ancient Rome, the Vestals or Vestal Virgins (Latin: Vestālēs, singular Vestālis [wɛsˈtaː.lɪs]) were priestesses of Vesta, goddess of the hearth. The College of the Vestals and its well-being were regarded as fundamental to the continuance and security of Rome. They cultivated the sacred fire that was not allowed to go out. The Vestals were freed of the usual social obligations to marry and bear children, and took a vow of chastity in order to devote themselves to the study and correct observance of state rituals that were off-limits to the male colleges of priests.
Livy, Plutarch, and Aulus Gellius attribute the creation of the Vestals as a state-supported priestesshood to king Numa Pompilius, who reigned circa 717–673 BC. According to Livy, Numa introduced the Vestals and assigned them salaries from the public treasury. Livy also says that the priestesshood of Vesta had its origins at Alba Longa. The 2nd century antiquarian Aulus Gellius writes that the first Vestal taken from her parents was led away in hand by Numa. Plutarch attributes the founding of the Temple of Vesta to Numa, who appointed at first two priestesses; Servius Tullius increased the number to four.Ambrose alludes to a seventh in late antiquity. Numa also appointed the pontifex maximus to watch over the Vestals. The first Vestals, according to Varro, were named Gegania, Veneneia, Canuleia, and Tarpeia. In myth, Tarpeia, daughter of Spurius Tarpeius, was portrayed as traitorous.
