Vatnshyrna

Vatnshyrna was a major Icelandic saga codex destroyed in the Copenhagen Fire of 1728. It was copied between 1391 and 1395 by Magnús Þórhallsson for Jón Hákonarson in northern Iceland. The codex was first called Vatnshyrna by Arngrímur Jónsson in his 1609 work, Crymogaea, possibly because it was located at that time at Stóra Vatnshorn.

Arngrímur refers to the codex containing the texts of Kjalnesinga saga, Þórðar saga hreðu, and Bárðar saga Snæfellsáss. A large part of the manuscript subsequently became part of Peder Resen's manuscript collection, and in 1675 this portion of the codex passed to Copenhagen University Library. At this point, the manuscript contained the following texts: Flóamanna saga Laxdæla saga Hænsna-Þóris saga Vatnsdæla saga Eyrbyggja saga Kjalnesinga saga Króka-Refs saga Stjörnu-Odda draumr Bergbúa þáttr Kumlbúa þáttr Draumr Þorsteins Síðu-Hallssonar Although destroyed in the fire, copies of all these texts, apart from Króka-Refs saga, had been made by Árni Magnússon and Ásgeir Jónsson. Margaret Clunies Ross has suggested that the manuscript's contents represent the compiler's "taste for the marvellous and the supernatural".
