¶1] Mag Ura, whence the name? Not hard to say. Colum Cille made a hymn in praise of Ciaran mac an tShaír after his death. Enna maccu Laigse received Colum Cille. Berchan was in Colum Cille's company, for he was his tutor, and from him he got the more part of his prophecies. The hymn was sold where Colum Cille's Cross stands on the green. Colum Cille was offered the monks' stock of kine, or two thousand ounces of silver; but he would accept nothing but three handfuls of Ciaran's earth. This was granted him, and he carried it with him to Mag Uatha. He sprinkled his three handfuls on this plain, and drove out the demons: for till then it was full of demons. So the name Mag Ura remained in memory of Ciaran's earth. The first name of the plain was Mag Derg, from Derg mac Dolair, who perished there. Afterwards, its name was Mag Uatha from Uath échtach, son of Feradach, who fell there in the battle of Mag Derg, in which the men of Connaught fought with Cormac Condloinges, the day before the sack of Bruiden Da Choca. In later times its name was Mag Ura, from the sprinkling of Ciaran's earth over it.
