In Celtic mythology, Luchtaine (or Luchta) was a son of Brigid and Tuireann and a god of craftwork and smithing. He was a member of the Tuatha Dé Danann.
Some say she was the mother of Creidhne (artificer), Luchta (carpenter) and Goibhniu (smith), the three master-craftsmen, though Goibhniu was usually called the son of Danu and Dian Cécht, and Luchta was the son of Luchad.
Sometimes, Luchta was called the son of Esarg and grandson of Neit, which make him the brother of Goibhniu, Credné and Dian Cécht.
Luchta was also known as the son of Ethliu, which make him the brother of Dagda, Nuada, Dian Cécht, Goibhniu, Credne and Lug Mac Cein.
Down through the ages, he has been called upon for protection, which makes sense, for healing and long life, and to ensure a good yield of butter...Now, just what does a smith have to do with butter?..Well you know, he had this marvelous cow, the Glas Ghaibhleann, and she could...well, we'll get to her later.
In his brewing activities he uses a vast bronze cauldron, a copy of which was housed in various sanctuaries and was aparently at times associated with the ritual slaughter of kings of Ireland.
As the Irish Welsh triple god Goibniu (Gobniu, Govannon, Luchtain, Luchtar, Luchta, Luchtainel, Credne), he was the anvil master goldsmith at Tara who made most of the weapons for the Tuatha De Danann, infusing them with protective blessings.
