Nuada Airgetlám
In Goidelic mythology, Nuada was one of the Tuatha de Danaan. He was a god of the sea, children and childbirth, the sun, beauty, healing, sorcery and poetry and writing. One of the four great treasures of the Tuatha de Danaan was his sword, which cut his enemies in half.
In the Second Battle of Magh Tuiredh, Nuada lost his arm. Since he was no longer perfect, his kingship was taken by Bres or Lugh. His brther, Dian Cecht, made him a silver hand to substitute. Bres then became a tyrant and was exiled. Nuada returned to the throne and was killed by Balor, the god of death.
