 According to the "Annals of Ulster", 22 March (Holy Wednesday) in 1122 was the day when the saint's shrine was discovered in the burial place of Lann.Kuno Meyer, who edited the "Life", suggests that this event may have prompted the composition of the text shortly after 1122 and also argues that there are linguistic grounds for assigning the text to the 12th century.The frequent use of such locational adverbs as "sund" ("here") seem to indicate that the "Life" was also written at Lann.
