last name appears in the 12th century geographical work Leiðarvísir ok Borgaskipan by the Icelandic abbot Nicolaus (d. 1161) and in Ynglinga saga by Snorri Sturluson, which indicates that the Icelanders considered Kievan Rus to have been founded by the Swedes. The name "Great Sweden" is introduced as a non-Icelandic name with the phrase "which we call Garðaríki" (sú er vér köllum Garðaríki), and it is possible that it is a folk etymological interpretation of Scythia magna. However, if this is the case, it can still be influenced by the tradition that Kievan Rus was of Swedish origin, which recalls Magna Graecia as a name for the Greek colonies in Italy. When the Norse sagas were put to text in the 13th century, the Norse colonisation of Eastern Europe, however, was a distant past, and little of historical value can be extracted. The oldest traditions were recorded in the Legendary sagas and there Garðaríki appears as a Norse kingdom where the rulers have Norse names, but where also dwelt the Dwarves Dvalin and Durin. There is, however, more reliable information from the 11th and the 12th centuries, but at that time most of the Scandinavian population had already assimilated, and the term Rus referred to a largely Slavic-speaking population. Still, Eastern Europe is presented as the traditional Swedish sphere of interest. The sagas preserve Old Norse names of several important Rus settlements, including (Novgorod), and (Kyiv); Fjodor Uspenskij argues that the use of the element in these names, as well as in the names and (Constantinople), shows the influence of Old East Slavic (city), as usually means farmstead in Old Norse. He further argues that the city names can be used to show that the Rus were also competent in Old East Slavic. At this time the Rus borrowed some 15 Old East Slavic words, such as the word for marketplace, tǔrgǔ, as torg, many of which spread to the other Old Norse-speaking regions as well. The most contemporary sources are the Varangian runestones, but just like the sagas, the vast majority of them arrive relatively late. The earliest runestone that tells of eastwards voyages is the Kälvesten runestone from the 9th century in Östergötland, but it does not specify where the expedition had gone. It was Harald Bluetooth's construction of the Jelling stones in the late 10th century that started the runestone fashion that resulted in the raising of
