Lugaid Mac Con

King of Munster. Lugaid Mac Con was the foster son of Ailill Aulomm. His foster brother was Eógan, his rival and enemy.

Lugaid had a loyal fool named Do Dera who looked exactly like him. The only thing to distinguish them apart was that Lugaid had very white legs.

They quarreled over the music-maker, Fer Í, son of Eogabal, which led them to confront each other on the battlefield at Cenn Abrat. Do Dera saw that his master was facing defeat and death, and advised Lugaid to let him impersonate the king, while Lugaid should escape.

Eógan thought that he had killed his foster brother, but recognised Lugaid's white legs, fleeing from the battlefield. Eógan couldn't prevent him from escaping to Scotland with only 27 of his companions.

Lugaid asked his surviving companions to not reveal his identity to the king of Scotland. The Alban king, however, suspected his true identity, and tested Lugaid by making Lugaid and his companions eat rats. Finally, the Alban king pressed Lugaid to reveal his true identity and offered to help Lugaid with his army to make him king of Munster.

So Lugaid returned to Munster, confronted by the combined army of Eogan and the high king Art Óenfher, at Maige Mucrama. Art and Eógan were killed in the fighting. Eógan fell at his hand, while Lugaid Lága (Lugaid's champion) killed Art.

Lugaid became king of Munster, as well as ruling in Tara as high king, but lost the throne seven years later, because of his false judgment in the case of an old woman's sheep. Forced to leave Tara, Lugaid returned to the home of his foster father. Cormac, son of Art, became the new high king of Ireland.

Lugaid thought Ailill Aulomm forgave him when Eogan's father kissed his cheek. To his horror, one side of Lugaid's face became disfigured because Ailill had a poisoned tooth. Half of his face was gone after three days, so he asked one of his followers to kill him.
