Possible third Jellinge stone found Archaeologists believe they have found a new Viking-era stone engraved with ancient Danish Rune writing Archaeologists from Vejle Museum think they may have found a third 'Jellinge stone' - a large rock with carved runes and considered the first examples of written language in Denmark. The researchers have found seven stones in all, which they believe date from the 10th century. Jellinge stones tell of the founding of Denmark and of Christianity's arrival in the country. Even if the stones do not yield a true Jellinge stone, the find is still significant.
