The manuscript might have been written in Iceland and soon moved into Norway[2] or have been composed in Norway.[3] It was found in Bergen in 1550 and brought to Denmark before 1600, when it was acquired by the collector Otto Friis, from whom it takes its name.[3] It then came into the possession of Jens Rosenkrantz before being bought in 1695 by Árni Magnússon. The latter gave it at his death (1730) to the University of Copenhagen.[4]
