Cormac mac Airt

Traditions vary. He is presented as son of Art mac Cuinn (son of Conn Céad Cathach) and his mother is Achtan in many accounts; medieval narratives include a prophetic vision by his mother that prefigures his kingship and prosaic death (a fishbone). Variants relate that in infancy he was carried off and fostered by a she-wolf and reared in caves near Kesh/Keash in Co. Sligo, later found by hunters; other accounts emphasize dynastic succession, judgment at Tara, battle for the throne, or abdication of rival kings. Sources thus present multiple versions of his early life and accession rather than a single canonical origin.

The supplied sources do not give a unified physical portrait beyond epithets and regnal markers. He is called Cormac Ulfada ('long beard') in some listings. Narrative contexts associate him with kingly regalia and monuments at Tara (Banqueting Hall, Cormac's house, Gráinne's Enclosure). The wolf-fosterage motif appears in origin narratives but is a fosterage trope rather than a literal consistent physical description.

Cormac is characterized for jurisprudential wisdom, learned counsel, exemplary judgment, and role as lawgiver and teacher; he is associated with Tecosca Cormaic ('The Instructions of King Cormac'), a gnomic instructional corpus. He is credited as patron-builder at Tara, acts as judge and dispenser of justice, and functions as a political and military actor in regnal narratives (campaigns, alliances, battles). The tradition does not attribute supernatural powers to him; his authority is social, legal, and political rather than magical.
