Battle of Moytirra I - The arrival of Lugh
It was as a result of the loss of his hand in this battle with the Fir Bolgs that Nuada got his name of Argetlam, that is, the Silver Handed . For Dian Cecht, the physician of the Tuatha Dé Danann, made him an artificial hand of silver, so skilfully that it moved in all its joints, and was as strong and supple as a real one. But, good as it was of its sort, it was a blemish; and, according to custom, no maimed person could sit upon the throne. Nuada was deposed; and the Tuatha Dé Danann went into council to appoint a new king.
They agreed that it would be a politic thing for them to conciliate the Fomors, the giants of the sea, and make an alliance with them. So they sent a message to Bres, the son of the Fomorian king, Elathan, asking him to come and rule over them. Bres accepted this offer; and they made a marriage between him and Brigit, the daughter of the Dagda. At the same time, Cian, the son of Dian Cecht, the physician of the Tuatha Dé Danann, married Ethniu, the daughter of the Fomors, Balor. Then Bres was made king, and endowed with lands and a palace; and he, on his part, gave hostages that he would abdicate if his rule ever became unpleasing to those who had elected him.
