Note 340 — Chapter IV · THE FAMILY OF IONA.
Reading edition
Adamnan, B. ii. c. 46. Boece states that the monastery was rebuilt by Maelduin, king of Dalriada, whose death is recorded by Tighernac in 690. He therefore reigned at the very time when Adamnan was abbot, and this fixes the date of these repairs as between 687 and 690.
