In 83 B.C.E. Sulla marched on Rome and the temple of Juppiter O.M was burned and reportedly the entire original Sibylline books. Plut. Sulla 2.7.6. Dion. Hal. 4.62.5-6. After Sulla the Senate established a commission in 76 B.C.E. to gather prophesies for the new collection of Sibylline Books. The comissioners went to the East but omitted Cumae, home of the Cumaean Sibyl.
