While the Roman religion has precious little written basis, they nonetheless had a very abstruse set of texts known as the Sibylline Books that were under the exclusive control of special religious figures, the duumviri (then decemviri). The books were resorted to solely in times of ultimate crisis. The devolution of these "sacred books" to the Romans through a rocambolesque scene, was attributed to an Etruscan, Tarquinius Superbus, the last of the legendary kings of Rome. Hence, their relationship to Vegoia.
