The Auctarium Prosperi Havniense (or Continuatio Prosperi Havniensis) is an anonymous continuation of the Chronicle of Prosper of Aquitaine, embodied in a manuscript at Copenhagen (, hence Havniense); it was given this appellation by Theodor Mommsen. Written in Latin in Italy, it covers the periods 455âÂÂ457 and 473âÂÂ625. It is an important source for the early Lombard kingdom.
