It is among the most significant works of Ottonian illumination. The manuscript was gifted to Bamberg Cathedral by Henry II, was part of the Cathedral treasury until 1803 when it became part of the Bavarian State Library as a result of Secularisation. It remains there today, stored under the inventory number clm 4456. It is modelled on the Codex Aureus of St. Emmeram donated by Charles the Bald in 870.[1]
