Magnús began his work at Auðkúla in 1607 after he had been dismissed from his office as parish minister, and completed his new redaction during the winter of 1608–09.
Magnús would later serve as the priest at Laufás parish in Northern Iceland and as a consequence his version of the Edda is usually referred to as the Laufás-Edda.
[1] The purpose of his efforts was to make a systematic and encyclopedic version of Snorri Sturluson's Prose Edda.
The myths in Gylfaginning are presented as a series of examples (dæmisögur) and the kennings of Skáldskaparmál are organized alphabetically by subject.
The Laufás-Edda, especially through Resen's edition, became a convenient and popular work of reference for poets and antiquarians, serving as an encyclopedia for researching both myth and poetic language.
