Despite its fame as the pre-eminent medieval Icelandic saga, Njáls saga lacks a stemma comprehending all the saga’s manuscripts: only the vellum manuscripts have been surveyed in detail. As part of the Variance of Njáls saga (Breytileki Njáls sögu) project, we produced a stemma of nearly all witnesses to chapters 44, 86, and 142. This affords the first systematic insight into the post-medieval manuscript transmission of the saga. The present article focuses on two aspects of the post-medieval transmission which turn out to be of particular interest: the huge popularity of the lost medieval manuscript *Gullskinna in the post-medieval scribal tradition, and a revision of the branch of the Njáls saga stemma labelled as *Y by Einar Ólafur (noted for being represented by Oddabók, AM 466 4to).
