My own personal observations would have me conclude, that while written or oral narratives are not confined to a specific style, it would seem that the cultures in which they are told possess an overarching narrative sense of style. For example, in Germanic cultures it seems like a very common narrative style for the progression of a story to be powered by the actions of characters, like in Beowulf, which subsequently inspired the narrative style of J.R.R. Tolkien. Likewise, Roman stories and legends feel very factual and solid, compared to the loose and fluffy Celtic fairy tales we have today.

That being said, out of the entirety of Celtic Europe, are there any surviving stories, legends, myths, or epics from the Celtic world that paint an accurate picture of the way the Celts viewed and interacted with the world, both emotionally and spiritually? If there are, do they carry a distinctive Celtic sense or narrative style that would be unique from others; Germanic or Greco-Roman for instance.

Any answers or replies would be eternally grateful, as well as any resources and books which deal with the topic. Thanks!
