In Irish mythology, Nuada or Nuadu (modern spelling: Nuadha), known by the epithet Airgetlám (Airgeadlámh, meaning "silver hand/arm"), was the first king of the Tuatha Dé Danann.
"[2] The name Nuada may derive from a Celtic stem *noudont- or *noudent-, which J. R. R. Tolkien suggested was related to a Germanic root meaning "acquire, have the use of", earlier "to catch, entrap (as a hunter)".
[3] Similarly, Julius Pokorny derives the name from a Proto-Indo-European root *neu-d- meaning "acquire, utilise, go fishing".
During this first great battle at Mag Tuired, Nuada lost an arm[5] in combat with the Fir Bolg champion Sreng.
The Tuatha Dé gained the upper hand in the battle, but Sreng later returned to challenge Nuada to single combat.
[7] Bres, aided by the Fomorian Balor of the Evil Eye, attempted to retake the kingship by force, and war and continued oppression followed.
[9] In The Fate of the Children of Tuireann Nuada is described as having a one-eyed door-keeper, whose eye is replaced by the brother healers Miach and Oirmiach with that of a cat.
Gaible stole a bundle of sticks from the Dagda's daughter (named as Ainge), and where he hurled them, a fair wood grew.
"[16] Nuada's name is cognate with that of Nodens, a British deity associated with the sea and healing who was equated with the Roman Mars, and with Nudd, a Welsh mythological figure.
