The Murder
Before the Second Battle of Mag Tuired, the Tuatha De Danann prepared for war against the Fomorians. Lugh Lamfada sent his father Cian to summon the warriors of Ulster, and Cian traveled north across the plain of Muirthemne.
There he saw three warriors approaching: Brian, Iuchar, and Iucharba, the three sons of Tuireann. Between their family and Cian's ran a blood feud of many generations. Cian knew he could not defeat all three, so he struck himself with a druid's wand and transformed into a pig, joining a nearby herd.
But Brian had seen the transformation. "One of those pigs is a man," he told his brothers. "Let us hunt them all until we find him."
They drove the herd, and one pig ran apart from the others. Brian cast his spear and wounded it. Cian resumed his human form.
"You have found me," Cian said. "But know that if you kill me in my true shape, you must pay an eric-fine. And the weapons that kill a man pay a higher fine than those that kill a pig."
"Then we will kill you with stones," Brian replied, "which have never paid eric for any man."
They stoned Cian until he was a mass of broken flesh, then buried him in the earth. The ground rejected his body seven times before it would accept him.
