It is a theory that proclaims the mythical and mystical origin of the Basque people. According to her, they were descendants of Tubal, one of the grandsons of Noah. It is attributed to Tubal Foundation of Tafalla and Tudela in Navarre and his descendants the Foundation of other cities of the Caucasus and Tobolsk, the capital of Siberia.
Historiographical assumption about our ethnic origin, who have mostly stood some Basques, placing our ancestors in the biblical figure Tubal (2 10 Genesis), fifth son of Japheth and grandson of Noah. Tubal would have emigrated with his family from Asia minor to the area of the Caucasus (Eastern Iberia) and from there to Western Iberia. The hypothesis would also be based on eponyms and toponymic names of both Iberias.
