Dôn

In medieval Welsh sources Dôn appears as an ancestral mother who gives rise to a family of important mythic personages often referred to as the 'Children of Dôn.' Bonedd yr Arwyr (the Gentry of the Heroes) supplies an extended list of named offspring (for example Gwydion, Arianrhod, Gilfaethwy and others such as Aidden, Cynan, Digant, Elawg, Elestron, Eunydd, Hedd, Hunawg, Idwal). Medieval tradition maps members of her house onto landscape and sky: Llys Dôn ('The Court of Dôn') is the traditional Welsh name for the constellation Cassiopeia; Caer Gwydion is used for the Milky Way; Caer Arianrhod for Corona Borealis. Early modern antiquarians sometimes treated Dôn as male, a reception-history detail noted in the sources rather than a feature of the medieval portrayal.

The supplied medieval and reference material does not record a specific physical or iconographic description of Dôn. She is presented in textual genealogy and toponymy rather than in accounts of bodily form or depiction.

No specific acts, powers, or interventions are attributed to Dôn in the provided sources; her significance in the material is genealogical and cosmological. Powers and deeds in the corpus are normally ascribed to individual members of her household (for example Gwydion or Arianrhod) rather than to Dôn herself.
