The Oral Tradition: Preservation and Transformation

Celtic mythology was primarily an oral tradition, passed down through generations by bards and druids.

However, the advent of Christianization and the subsequent recording of these myths in medieval manuscripts, such as the Lebor Gabála Érenn (The Book of Invasions) and the Táin Bó Cúailnge (The Cattle Raid of Cooley), ensured their survival. The transcription of these stories in the 11th and 12th centuries provided a more permanent record, yet also introduced Christian elements that transformed the original pagan narratives.

The bards, highly respected in Celtic society, served not only as storytellers but also as historians and genealogists. Their role in preserving the lineage and deeds of their people was crucial.
