Sibylline Books
In particular, the keepers of the "Sibylline Books" had the superintendence of the worship of Apollo, of the "Great Mother" Cybele or Magna Mater, and of Ceres, which had been introduced upon recommendations as interpreted from the "Sibylline Books". The "Sibylline Books" motivated the construction of eight temples in ancient Rome, aside from those cults that have been interpreted as mediated by the "Sibylline Books" simply by the Greek nature of the deity. Thus, one important effect of the "Sibylline Books" was their influence on applying Greek cult practice and Greek conceptions of deities to indigenous Roman religion, which was already indirectly influenced through Etruscan religion. As the "Sibylline Books" had been collected in Anatolia, in the neighborhood of Troy, they recognized the gods and goddesses and the rites observed there and helped introduce them into Roman state worship, a syncretic amalgamation of national deities with the corresponding deities of Greece, and a general modification of the Roman religion.
