Abstract
<jats:p>The medieval code of laws Grágás (“Grey Goose”) has come down to us in several independ-ent manuscripts. The two oldest and most complete are GKS 1157 fol (Konungsbók) and AM 334 fol (Staðarhólsbók). Both codices were created in the second half of the 13th century. Both manuscripts contain largely identical text. Despite partial damage, the manuscripts are suitable for source study. Their condition and numerous owner’s notes indicate that the text was actively read, and commented on. A comparison reveals that the text of Grágás in AM 334 fol is in some places abridged and incomplete compared to GKS 1157 fol. Each manu-script has its own structure and composition; they sometimes complement each other, and sometimes contradict each other. GKS 1157 fol contains sections on the organization of politi-cal issues not found in AM 334 fol, and it can be considered more comprehensive than AM 334 fol. However, AM 334 fol has a more clearly defined structure. Perhaps the discrepancies between the manuscripts reflect different interpretations of the law by the legal tradition of the time.</jats:p>
