Vegoia (Etruscan: Vecu) is a sibyl, prophet, or nymph within the Etruscan religious framework who is identified as the author of parts of their large and complex set of sacred books, detailing the religiously correct methods of founding cities and shrines, draining fields, formulating laws and ordinances, measuring space and dividing time; she initiated the Etruscan people to the arts, as originating the rules and rituals of land marking, and as presiding over the observance, respect, and preservation of boundaries.
There being few bilingual documents comparable to the Rosetta Stone that could facilitate translation, the Etruscan language is poorly understood.
Therefore, the existing ancient Etruscan documents of the eighth, seventh, and sixth centuries BCE that would reveal their religious concepts, do not yield much.
Lastly, while the Etruscans formalized their religious concepts and practices in a series of "sacred books", most no longer exist and they are known only through commentaries or quotes by Roman authors of the late first century,[a] and hence, may be biased.
She is barely designated as a "nymph" and as the author of the Libri Fulgurales,[5] that give the keys to interpreting the meaning of lightning strokes sent by the deities using a cartography of the sky that, as a sort of property division and use assignment, is attributed to Vegoia.
[8] 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 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.
