[Footnote 239: It is printed in Rafn, pp. 84-187, and in _Groenlands historiske Mindesmaerker_, i. 352-443. The most essential part of it may now be found, under its own name, in Vigfusson's _Icelandic Prose Reader_, pp. 123-140.] [Sidenote: The northern or Flateyar-bok version.] The northern version is that which was made about the year 1387 by the priest Jon Thordharson, and contained in the famous compilation known as the _Flateyar-bok_, or "Flat Island Book."[240] This priest was editing the saga of King Olaf Tryggvesson, which is contained in that compilation, and inasmuch as Leif Ericsson's presence at King Olaf's court was connected both with the introduction of Christianity into Greenland and with the discovery of Vinland, Jon paused, after the manner of mediaeval chroniclers, and inserted then and there what he knew about Eric and Leif and Thorfinn. In doing this, he used parts of the original saga of Eric the Red (as we find it reproduced in the western version), and added thereunto a considerable amount of material concerning the Vinland voyages derived from other sources. Jon's version thus made has generally been printed under the title, "Saga of Eric the Red."[241] [Footnote 240: It belonged to a man who lived on Flat Island, in one of the Iceland fiords.] [Footnote 241: It is printed in Rafn, pp. 1-76, under the title "Thaettir af Eireki Rauda ok Graenlendingum." For a critical account of these versions, see Storm, _op. cit._ pp. 319-325; I do not, in all respects, follow him in his depreciation of the Flateyar-bok version.] [Sidenote: Presumption against sources not contemporary.]
