Now when entering Connaught Diarmait went to Clonmacnois, and St. Ciarán's community, with their abbot Aed-lug, son of Cumman, did penance to God for him that he might come (back) safe by virtue of their guarantee. So the king (after returning in triumph) offered him Tuaim n-Eirc with its subdivisions of land — i.e. Liath Mancháin — as a 'sod on altar' to God and to St. Ciarán, and he bestowed three curses on the king of Meath (for the time being) if any of his people should consume (as a right) even a drink of water therein. Wherefore no king of Meath ventures to look at it, and none of his people ventures to partake of its food.
Hence it is that Diarmait requested his burial in Clonmacnois, wherefore he was after interred therein.
