 Worship of Vesta, like the worship of many gods, originated in the home, but became an established cult during the reign of either Romulus, or Numa Pompilius (sources disagree, but most say Numa).The priestesses of Vesta, known as Vestal Virgins, administered her temple and watched the eternal fire.Their existence in Alba Longa is connected with the early Roman traditions, for Romulus' mother Silvia was a priestess.
