As for the Dindshenchas and its folklore tying the monastery at Slane to themes of kingship and judgement, Conor Brady notes that "the folklore related in the Dindsenchas may not be very ancient. The text itself is 12th century but records earlier (or contemporary?) stories/traditions. It is possible that the folklore there is a reinforcement of the existing status of the monastery on the Hill of Slane as a legal centre." (Brady, Conor. Email to the author, Jan. 2, 2020.)
