Scientists find Arabian artifacts in rocky Viking cave boat

The transcript discusses the discovery of an ancient Viking site in Iceland, located in a lava pipe from a volcanic eruption 1100 years ago. The Vikings, who had recently settled in Iceland, were likely disturbed by the eruption. After the lava cooled, they constructed a boat-shaped structure in a cave and performed rituals involving burning animal bones. These actions may have been intended to appease the giant Serter, who was believed to bring about Ragnarok, or to empower the fertility god Frere to prevent the world's fiery end.
