As George Petrie retold the story in 1845: "...he came by his death at the house of Cletech, the bone of  a salmon having stuck in his throat. And he (Cormac) told his people not to bury  him at Brugh, (because it was a cemetery of Idolaters,) for he did not worship the  same God as any of those interred at Brugh ; but to bury him at Ros na righ, with  his face to the east. He afterwards died, and his servants of trust held a council, and  came to the resolution of burying him at Brugh, the place where the kings of Tara,  his predecessors, were buried. The body of the king was afterwards thrice raised to be  carried to Brugh, but the Boyne swelled up thrice, so as that they could not come ; so  that they observed that it was ' violating the judgment of a prince' to break through  this Testament of the king, and they afterwards dug his grave at Ros na righ, as he  himself had ordered."
