[All]: This and the following stanza derive from the following in DGB 106 (Reeve and Wright 2007, 137.499-503): Vocatis denique magis suis, consuluit illos iussitque dicere quid faceret. Qui dixerunt ut aedificaret sibi turrim fortissimam quae sibi tutamen foret, cum ceteras munitiones amisisset … Venit tandem ad montem Erir, ubi coadunatis ex diuersis patriis caementariis iussit turrim construere ‘Finally he summoned and consulted his magicians, commanding them to tell him what to do. They said that he should build a very strong tower as a refuge, since he had lost his other fortresses … he came at last to Mount Snowdon, where he gathered stonemasons from various regions and ordered them to build the tower’ (Reeve and Wright 2007, 136).
