Gaelic mythology refers to the traditional stories and beliefs of the Gaelic-speaking peoples of Ireland and Scotland. It encompasses a rich tapestry of tales involving gods, heroes, and supernatural beings, often reflecting the natural world and human experiences. Key figures include Cú Chulainn, a legendary warrior, and Brigid, a goddess associated with fertility and healing. These myths were passed down orally and later recorded in texts like the Book of Kells and the Táin Bó Cúailnge. They often explore themes of heroism, fate, and the interplay between the mortal and divine realms, providing insight into the values and culture of ancient Gaelic societies.
