The Annals of Ulster and the date of the meeting of Druim Cett

Source-criticism of the sixth-century entries in AU supports Sharpe’s redating of the meeting at Druim Cett (AU s.a. 574) to c.590. AU’s Druim Cett entry was composed by a twelfth-century compiler as part of a stratum of additions and duplications to fill empty years in AU’s main source, the so-called ‘Chronicle of Ireland’.
