Lugaid Laigdech, son of Eochu mac Ailella, was, according to medieval Irish legend and historical tradition, a High King of Ireland.
[3] Keating refers to a story that Lugaid, when hunting, once met a hideous hag wearing a magic mask.
Keating interprets this as an allegory of Ireland, meaning that Lugaid first endured toil and torment, and then enjoyed pleasure, over her.
He also tells a story from the Cóir Anmann ("fitness of names") about a certain Lugaid Loígde, one of the five sons of Dáire Doimthech, all of whom were called Lugaidh.
When Dáire asked which one, he was told to take all five to Tailtiu and pursue a beautiful fawn which would appear to them there, and the one who outran it would be king.
