I like this guy. He had a magic club that killed with one end and brought back to life with the other. His cauldron had neverending food and he had a roasting pig that never ran out. He was the god of life, death, banquets, war and magic. If you think about it he sounds pretty familiar.
I had always heard him associated with metallurgy/blacksmithing too. The Goddess Brigit is his daughter - she's my favorite. Goddess of Light, Healing, and Wisdom.
I believe you are thinking of Goibniu, the blacksmith to the gods. Brigid is associated with him because she too is a deity of fire. She uses fire to warm the earth, thus starting springtime. This happens on Feb. 1. (Imbolc). It is believed that in medieval times, there was a Christian order in Kildare of women only clerics dedicated to Brigid. They kept a sacred fire perpetually burning. St Brigid is second only to St. Patrick in importance in Ireland.
