in Roman religion, six priestesses, representing the daughters of the royal house, who tended the state cult of Vesta, the goddess of the hearth. The cult is believed to date to the 7th century BC; like other non-Christian cults, it was banned in AD 394 by Theodosius I.

Chosen between the ages of 6 and 10 by the pontifex maximus (“chief priest”), Vestal Virgins served for 30 years, during which time they had to remain virgins. Afterward they could marry, but few did. Those chosen as Vestal Virgins had to be of the required age, be freeborn of freeborn and respectable parents (though later the daughters of freedmen were eligible), have both parents alive, and be free from physical and mental defects. They lived in the House of the Vestal Virgins on the Roman Forum, near the Temple of Vesta. Their duties included tending the perpetual fire in the Temple of Vesta, keeping their vow of chastity, fetching water from a sacred spring (Vesta would have no water from the city water-supply system), preparing ritual food, caring for objects in the temple's inner sanctuary, and officiating at the Vestalia (June 7–15), the period of public worship of Vesta. Failure to attend to their duties was punished by a beating; violation of the vow of chastity, by burial alive (the blood of a Vestal Virgin could not be spilled). But the Vestal Virgins also enjoyed many honours and privileges not open to married or single women of equivalent social status, including emancipation from their fathers' rule and the ability to handle their own property.
