Codex Frisianus

Codex Frisianus or Fríssbók (shelfmark AM 45 fol. in the Arnamagnæanske samling) is a manuscript of the early fourteenth century (c. 1300–1325). Among its 124 folios, it contains Heimskringla (without the Saga of Saint Olaf) and Hákonar saga Hákonarsonar.

Origins and history
The manuscript might have been written in Iceland and soon moved into Norway or have been composed in Norway. 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. 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.
