the Quindecimviri ("The Fifteen"), and the epulones were opened to any member of the senatorial class. To restrain the accumulation and potential abuse of priestly powers, each gens was permitted one priesthood at any given time, and the religious activities of senators were monitored by the censors. Magistrates who held an augurate could claim divine authority for their position and policies. In the late Republic, augury came under the control of the pontifices, whose powers were increasingly woven into the civil and military cursus honorum. Eventually, the office of pontifex maximus became a de facto consular prerogative. Some cults may have been exclusively female; for example, the rites of the Good Goddess (Bona Dea). Towards the end of the second Punic War, Rome rewarded priestesses of Demeter from Graeca Magna with Roman citizenship for training respectable, leading matrons assacerdotes of "Greek rites" to Ceres. Every matron of a family (the wife of its pater familias) had a religious duty to maintain the household fire, which was considered an extension of Vesta's sacred fire, tended in perpetuity by the chaste Vestal Virgins. The Vestals also made the sacrificial mola salsa employed in many State rituals, and represent an essential link between domestic and state religion. Rome's survival was thought to depend on their sacred status and ritual purity. Vestals found guilty of inchastity were "willingly" buried alive, to expiate their offence and avoid the imposition of blood-guilt on those who inflicted the punishment. Temples and festivals Rome's major public temples were contained within the city's sacred, augural boundary (pomerium), which had supposedly been marked out by Romulus, with Jupiter's approval. The Temple of Jupiter Optimus Maximus ("Jupiter, Best and Greatest") stood on the Capitoline Hill. Among the settled areas outside the pomerium was the nearby Aventine Hill. It was traditionally associated with Romulus' unfortunate twin, Remus, and in later history with the Latins, and the Roman plebs. The Aventine seems to have functioned as a place for the introduction of "foreign" deities. In 392, Camillus established a temple there to Juno Regina, Etruscan Veii's protective goddess. Later introductions include Summanus, 278, Vortumnus 264, and at some time before the end of the 3rd century, Minerva. While Ceres' Aventine temple was most likely built at patrician expense, to mollify the plebs, the patricians brought the Magna Mater ("Great mother of the Gods") to Rome as their own "Trojan" ancestral goddess, and installed
