to as pontifices Vestae ("priests of Vesta"). In 12 BC, 28 April (first of the five day Floralia) was chosen ex senatus consultum to commemorate the new shrine of Vesta in Augustus' home on the Palatine. The latter's hearth was the focus of the Imperial household's traditional religious observances. Various emperors led official revivals and promotions of the Vestals' cult, which in its various locations remained central to Rome's ancient traditional cults into the 4th century. Dedications in the Atrium of Vesta, dating predominantly AD 200 to 300, attest to the service of several Virgines Vestales Maxime. Vesta's worship began to decline with the rise of Christianity. In ca. 379, Gratian stepped down as pontifex maximus; in 382 he confiscated the Atrium Vestae; simultaneously, he withdrew its public funding. In 391, despite official and public protests, Theodosius I closed the temple, and extinguished the sacred flame. Finally, Coelia Concordia stepped down as the last Vestalis Maxima ("chief Vestal") in 394. Depictions Depicted as a good-mannered deity who never involved herself in the quarreling of other gods, Vesta was ambiguous at times due to her contradictory association with the phallus.

Mythographers tell us that Vesta had no myths save being identified as one of the oldest of the gods who was entitled to preference in veneration and offerings over all other gods. Unlike most gods, Vesta was hardly depicted directly; nonetheless, she was symbolized by her flame, the fire stick, and a ritual phallus (the fascinus). While Vesta was the flame itself, the symbol of the phallus might relate to Vesta's function in fertility cults, but it maybe also invoked the goddess herself due to its relation to the fire stick used to light the sacred flame. She was sometimes thought of as a personification of the fire stick which was inserted into a hollow piece of wood and rotated – in a phallic manner – to light her flame. Hearth Concerning the status of Vesta's hearth, Dionysius of Halicarnassus had this to say: "And they regard the fire as consecrated to Vesta, because that goddess, being the Earth and occupying the central position in the universe, kindles the celestial fires from herself." Ovid agreed,
