In Irish mythology, Dian Cecht was a god of healing. He was the healer for the Tuatha Dé Danann and the father of Cian.
He blessed a well called Slane so that the Tuatha Dé could bathe in when wounded; they became healed and continued fighting. It would heal any wound but decapitation.
He made King Nuada's silver arm. Dian Cecht's son, Miach, replaced the silver arm with an arm of flesh and blood; Dian Cecht killed him out of professional envy.
Dian Cecht's healing powers were invoked in Ireland as late as the 8th century.
