Note 4 — PART I

Tigernach gives the date as 624, which Dr. Reeves is inclined to accept, op. cit. Introduction, xl-xli. Lanigan is in favour of 627, which agrees with the reputed age of Adamnán, 77, at the time of his death. Possibly the latter date is correct, the difference being explicable by the different system of chronology adopted by Tigernach.
