Stefán Karlsson has connected the composition of Guðmundar sögur A, B, and possibly C, to the translation of Guðmundur's relics by Bishop Auðunn rauði Þorbergsson in 1314, while Guðmundar saga D was apparently composed by Arngrímr Brandsson for the second translation of Guðmundur's relics by Bishop Ormr Ásláksson in 1344.
It was probably under Ormr's auspices that Arngrímr Brandsson composed the D-version of Guðmundar saga biskups.
