Also, on that Illiteracy - the Gauls of now-France (soon to be Assfuckistan) and the Irish - pretty much all the Celts - had oral traditions. That they did not write things down, does not make them illiterate in the spirit of the word. They were far from it. Julius Caesar records in his annals of the Gallic wars that their Druids could recite whole histories off the tops of their heads, and the sons of nobles and leaders clamored to be accepted into the druidical fold, for such education. Many of the Gallic nobles were, in fact, literate, and could typically write in at least Latin, their own languages having no writing system at that time. This would change by at least the 8th century.
