Quindecemviri sacris faciundis
From Wikipedia, the free encyclopedia
The quindecemviri sacris faciundis were the fifteen members of a college for less clearly defined religious duties. Most notably they guarded the Sibylline Books and it was for them to consult these scriptures and interpret them when requested to do so by the Senate. The Sibylline Books being evidently understood as something foreign by the Romans, this college also was to oversee the worship of any foreign gods which were introduced to Rome.
