Okay, so a long long time ago in ancient Rome, there were some women who were picked to be very special ladies. They were called "vestal virgins." They lived in a big temple and their job was to keep the sacred fire burning all the time.
These ladies were supposed to be really pure and not have any husbands or boyfriends, so they were always called "virgins." They couldn't even touch men or have any babies. If they did, they would be in big trouble.
These vestal virgins were so important that people would come from all over to see them and ask them for advice. They also had special jobs during some big holidays, like making special cakes and dressing up in fancy clothes.
It was a big honor to be chosen as a vestal virgin but also meant that they could never get married or have a family of their own. Some people thought it was a little bit sad, but it was seen as a really special job that only the most dedicated and pure-hearted women could do.
