Celtic Mythology - All the Important Stories and Characters

The source provides an extensive overview of Celtic mythology, which is characterized as a fragmented "mosaic" primarily preserved through medieval Christian manuscripts because the ancient Celts favored oral tradition. The text details the two main branches of insular mythology: Irish (Goidelic), organized into four great cycles like the Mythological and Ulster Cycles, and Welsh (Brythonic), which largely survives in the Mabinogion and Arthurian precursors. Specific attention is paid to major figures, such as the powerful Irish gods the Tuatha Dé Danann and the tragic hero Cú Chulainn, alongside key mythological plots like the Táin Bó Cúailnge. Furthermore, the source identifies core themes that unify these traditions, including the importance of Sovereignty Goddesses, the destructive nature of the geis (taboo), and the cultural significance of the Head Cult and shape-shifting.
