Ailill Angubae

Ailill Angubae appears in the Lebor na hUidre version of the medieval Irish tale The Wooing of Étaín as a member of the royal household: brother to the High King Eochaid Feidlech. He becomes enamored of Étaín after she is brought to Tara and married to Eochaid. His role in the narrative is that of a human whose life is devastated by illicit love and whose fate is altered by intervention from the Tuatha Dé Danann.

The sources do not provide a concrete physical description. Narrative summaries state only that Ailill 'gradually succumbed to a wasting disease brought on by his feelings,' implying a progressive decline in health rather than detailing clothing, features, or stature.

Ailill is depicted as a mortal man without supernatural powers. His notable behaviors are emotional and social: he falls in love with his brother's wife, experiences a pathological decline in health attributed to his passion, and arranges a meeting with Étaín which he fails to keep because Midir casts him into an enchanted sleep. He is therefore characterized by human desires and vulnerability to otherworldly magic rather than by any innate magical capability.
