Note 602 — Chapter VII · THE COÄRBS OF COLUMCILLE.
Reading edition
He is said in the Life to have died in the seventieth year of his age and the thirtieth of his pilgrimage, but it began when Constantin was king of Alban, and Eric ruled at York. Eric’s reign at York began about 938, and Constantin died in 942, which limits us to four years for the year of his birth.
