Goibniu

In Irish mythology Goibniu (Old Irish, pronounced ˈɡovʲnʲu) or Gaibhne (Modern Irish) was the smith of the Tuatha Dé Danann. He is believed to have been a smithing god and is also associated with hospitality.

The name of his father appears as Esarg or Tuirbe Trágmar, the 'thrower of axes'. Goibniu is often grouped together with Credne the silversmith and Luchta the carpenter as the Trí Dée Dána (three gods of art), who forged the weapons which the Tuath Dé used to battle the Fomorians. Alternatively, he is grouped with Credne and Dian Cecht the physician. When Nuada's arm is cut off in battle, Goibniu crafts him a new one of silver. He also makes weapons for the gods. In the Lebor Gabála Érenn, he is described as "not impotent in smelting", and is said to have died, along with Dian Cecht, of a "painful plague".
