102 GRIPLA the leader in various sports (cf. perhaps Grettir's encounter with Björn Hítdælakappi) and then reluctantly kills him in battle. On the hero's subsequent trip to Denmark, he gives the gloves to King Harald and is well rewarded, before returning to Earl Hákon (cf. Auðunar þáttr). While at the latter's court, Þjóstólfr is baited by Már and they part after having words (cf. Björn and Grettir at Þorkell's farm). Þjóstólfr takes a wife (unlike Grettir) before engaging in a troll episode similar to that at Sandhaugar. He then visits King Ólaf Tryggvason and is bap- tized, an event which proceeds much more smoothly than does Grettir's baptism. Both sagas end with a tour of duty in the Varangian guard in Miklagarð. It is obvious both that Þjóstólfs saga has borrowed from Grettis saga and that Adeldahl was familiar with the story. He copied in Nks. 1134, fol. from AM 614a-b, 4to Jón Guðmundsson's versified version of the saga, not yet edited: "Litid Inntak Grettirs Saugo í rímur snuid." Auð- unar þáttr was also known to Adeldahl, for he copied it from AM 217c, fol. as Nks. 1702, 4to. Even the aquatic battle with the bear can be found in a manuscript (AM 162c, fol.) transcribed by Adeldahl as Nks. 1785, 4to. Although he did not copy Finnboga saga ramma, itself, it is probable that he at least knew the title, which could well have suggested the epithet in the title of his own work. The corresponding aquatic battle in Vilmundar saga was also known to Adeldahl's colleague, M. Magnusen, who knew the story from two manuscripts, copying it once from AM 586, 4to as Nks. 1250, fol. Since Suhm has made no comments on the Þjóstólfs saga manuscript, and since Kálund has not attributed it to Suhm's library, it is probable that a different collector purchased the bogus work. Assuming only one copy of the forgery was ever produced, practically the only possible candidate can be Professor Bernhard M011mann, head librarian of the Royal Library in Copenhagen from 1748 to his death on July 25, 1778. The auction catalog of M0llmann's personal library lists among the 850 manuscripts the "Saga af Þióskolfi Hamrama Svarfdælskum."16 The fact that M0llmann was half blind in his later years and that he possessed a reputed soft spot in his heart for needy students certainly made him an ideal person to be deceived by the hoax.17 Furthermore, 18 Recensio Librorum qvos relinquebat moriens Bernh.
