Drauma-Jóns saga (the story of Dream-Jón) is one of the medieval Icelandic chivalric sagas, written in Old Norse around the early fourteenth century. It is a comparatively short work compared to others of the genre, and is really more an exemplum than a saga, similar in this respect to the chivalric saga Clarus saga and the ævintýri ('exempla') associated with Jón Halldórsson. The work has been attributed to the monk Bergr Sokkason, abbot of Munkaþverá; at any rate it seems characteristic of the work of the North Icelandic Benedictine School. It was a very popular story, to judge by the number of surviving manuscripts discovered: five on parchment and 45 on paper, with one prominent manuscript being AM 510 4to. The tale may have Oriental origins. Source: Wikipedia (en)
