Runestones are one of the most important sources that give us insight into Scandinavia between the 4th and 12th centuries. They were carved using a unique manuscript called Futhark which is divided into two variants, the younger and the older Futhark. Even though the oldest known rune stones date back to the 4th century, the vast majority of them were carved during the Viking era using the younger Futhark variant. The stones differed in size and shape, and were often painted in a variety of colors, most commonly red and black. Today, rune stones provide an insight into the culture and lifestyle of Vikings but are also a portrayal of societal relations and norms, riches, inheritance, and communication. Most of them were erected as commemorative symbols, and they often depict the religion of that period in Scandinavia. It is important to note that the stones were not the only source of runic inscriptions, but that they were also found on various commonplace items in households all over Scandinavia, which further deepens our knowledge of the Viking culture. Considering their unique history, along with the value that they hold for scientists, they are an invaluable source for linguistic, archeological, and cultural research.
