The Ancient Celtic period spans the early mythological and tribal cultures of Celtic Europe, including regions of modern-day Ireland, Scotland, Gaul, and Iberia. This era is known for its oral traditions, sacred landscapes, and deities like the Cailleach, Lugh, and Danu, who shaped natural forces and cycles.Celtic mythology from this time emphasizes transformation, nature worship, and seasonal cycles. Stories of gods, goddesses, and primal beings emerged in this period, laying the foundation for Gaelic and Brittonic folklore. Many of these myths were preserved through bardic tradition and later Christian transcription.
