Criomhthain

Criomhthann is a mythical figure from Irish mythology, appearing in the Ulster Cycle of the Mythological Cycle. He is the son of the Dagda, the chief god of the Tuatha Dé Danann, and the father of Aengus, the god of youth and beauty. Criomhthann is known for his role in the events leading to the Tuatha Dé Danann's defeat by the Milesians.

Criomhthann is described as a skilled warrior and a powerful magician. He is credited with the invention of the harp, which he presents to the Milesian king, Eochaid mac Eirc, as a gift. However, the harp is later stolen by the Milesians, and Criomhthann's son, Aengus, is killed in revenge. This event is seen as a turning point in the conflict between the Tuatha Dé Danann and the Milesians, ultimately leading to the former's defeat.

Criomhthann's story is significant in Irish mythology as it highlights the themes of the loss of the Golden Age and the transition from the Tuatha Dé Danann to the Milesian era. His character serves as a bridge between the two cultures, showcasing the skills and knowledge of the Tuatha Dé Danann that are eventually absorbed by the Milesians.

Despite his importance in the Ulster Cycle, Criomhthann is not as widely known as some other figures in Irish mythology. His story is primarily told in the tale "The Wooing of Étaín," which is part of the Ulster Cycle. The tale provides insight into the political and cultural dynamics of early Ireland, as well as the complex relationships between the Tuatha Dé Danann and the Milesians.
