Sibylline Oracles
From Tardis Wiki, the free Doctor Who reference
The Sibylline Oracles are a set of books of prophecy set down by the Sibyl and kept by the Sibylline Sisterhood for generations after.
The 13th book foretells that the appearance of the Blue Box, a temple made of wood, would appear in a time of storms and fire and betrayal. (DW: The Fires of Pompeii)
