|Jean Raoux 1727|
The chastity vow was so important that those that broke the vow were killed. This was done by burying the Vestal Virgin alive in Campus Scleleratus the "Evil Field" just outside the Servian Wall. While her lover was flogged to death on the Comittium. And if the sacred fire at the Temple of Vesta went out the Vestal Virgin it proved that she was impure.
Considering that the broken chastity vow was rare most of the women did their 30 year duty. Once the her time as a priestess was done she was given many privileges that normal Roman women did not have. They were not subject of their father's rules known as pater potestas, they could own their own property and engage in legal contracts, marry and have children. But most opted to remain single.
The end of the Vestal Virgins came in 394 A.D. when the Catholic Church banned non-Christian cults. Trying to give the general population a sense of familiarity, the Church adopted the use of conventsand positions that nuns held many of the same rules and customs of the Vestals.
