Dían Cécht did not like that cure. He hurled a sword at the crown of his son's head and cut his skin to the flesh. The young man healed it by means of his skill. He struck him again and cut his flesh until he reached the bone. The young man healed it by the same means. He struck the third blow and reached the membrane of his brain. The young man healed this too by the same means. Then he struck the fourth blow and cut out the brain, so that Míach died; and Dían Cécht said that no physician could heal him of that blow.
