Researchers from the NTNU have focused their attention on two of the grave boats found at Valsgarde, or rather, what was found inside of them.
The two boats measured about 32ft (10m) in length and symbolically carried the dead into the afterlife.
The dead themselves were likely high-ranking warriors, fitted with ornate helmets, swords and shields.
Their boats were fitted with a manner of supplies and tools, while animals and horses were arranged near to the boats.
Professor Berglund said: “The buried warriors appear to have been equipped to row to the underworld, but also to be able to get ashore with the help of the horses.”
One of the warriors was laid to rest alongside a beheaded eagle owl, also known as the Bubo bubo.
According to Professor Berglund, the beheading “had a ritual significance in connection with the burial”.
