Hauksbók

thumb|A page from Hauksbók Hauksbók (; 'Book of Haukr') is a 14th-century Icelandic manuscript created by Haukr Erlendsson. Significant portions of it are lost, but it contains the earliest copies of many of the texts it contains, including the Saga of Eric the Red. In most cases, Haukr copied from earlier, now lost manuscripts. Among these are the section on mathematics called Algorismus, the text of Hervarar saga ok Heiðreks. It was originally in one part, but now split in three (AM 371 4to, AM 544 4to and AM 675 4to) and held at the Árni Magnússon Institute for Icelandic Studies in Reykjavík, Iceland.

==Composition== Hauksbók is associated with an Icelandic lawspeaker named Haukr Erlendsson: although the work of several scribes, the vast majority is in Haukr's hand. Palaeographical evidence allowed Professor Stefán Karlsson, director of the Árni Magnússon Institute for Icelandic Studies, to date the manuscript to between 1302 and 1310. As long back as it is possible to trace the manuscript it has been called Hauksbók after him. Hauksbók is a compilation that includes Icelandic sagas and a redaction of Landnámabók. The book contains versions, often the only or earliest extant versions, of many Old Icelandic texts, such as Fóstbrœðra saga, the Saga of Eric the Red, Hervarar saga ok Heiðreks, and Völuspá. Haukr tended to rewrite the sagas that he copied, generally shortening them.
