The great god of healing and the physician of the Tuatha Dé Danann. He made the silver hand for his brother king Nuada to replace the one he lost in battle. Dian Cecht had blessed the well Slane in which the wounded Tuatha Dé bathed. It healed all their wounds so they could resume their fighting. He had a son, Miach, whom he slew out of professional jealousy. Miach had replaced the silver hand Dian Cecht had made for Nuada with Nuada's own hand. Some claimed it was jealousy, while Dian Cecht said is was the disrespectful manner in which the replacement was done. He is also the grandfather of Lugh.
