=25.= Vulcan, the god of fire and the forge, was honored by two festivals, the consecration of trumpets in May, and the Vol´cana´lia in August. Though of inferior rank to the divinities already mentioned, yet dearest of all to the Romans, were the gods of the hearth, the household, and store-room, and of the forest and field. Every house was a temple, and every meal a sacrifice to Vesta, the goddess of the hearth. Her temple was the hearth-stone of the city. There six chosen maidens, daughters of the most illustrious families, guarded the sacred fire, which was the symbol of the goddess, by night and day. Every house had over its main entrance a little chapel of the _La´res_, where the father of the family performed his devotions immediately on returning from any journey. The Lares were supposed to be the spirits of good men, especially the deceased ancestors of the family. Public Lares were the protecting spirits of the city; they were worshiped in a temple and numerous chapels, the latter being placed at the crossings of streets. There were also rural Lares, and _Lares Via´les_, who were worshiped by travelers. =26.= Like all people in any degree affected by Greek culture, the Romans consulted the Delphic oracle. After the capture of Ve´ii (see § 57), they presented that shrine with a tenth of the spoils. Rome itself possessed only one oracle, that of Faunus (the favoring god), on the Aventine Hill. Several oracles of Fortune, Faunus, and Mars existed in Latium, but in none of them were audible responses given, by the mouth of inspired persons, as at Delphi. At Albu´nea, near Tibur, Faunus was consulted by the sacrifice of a sheep. The skin of the animal was spread upon the ground; the person seeking direction slept upon it, and believed that he learned the will of the god by visions and dreams. The Romans frequently resorted to the Greek oracles in southern Italy; and the most acceptable gift which the inhabitants of Magna Græcia could offer to their friends in Rome, was a palm-leaf inscribed with some utterance of the Cumæan sibyl, a priestess of Apollo at Cumæ, near Naples. =27.= The Sibylline Books were believed to have been purchased by one of the Tarquins from a mysterious woman, who appeared at Rome offering nine volumes at an exorbitant price. The king refusing to purchase, the sibyl went away and destroyed three of the books; then brought back the remaining six, for which she asked the same amount of money. The king again sent her away; she destroyed three more books, and demanded the whole price for the remaining three. The curiosity of Tarquin was aroused, and he bought the books, which were found to contain important revelations concerning the fate of Rome. They were kept in a stone chest under the temple of Jupiter Cap´itoli´nus. One of the four sacred colleges was charged with the care of them, and they were only consulted, by order of the Senate, on occasions of great public calamity.
