In Norse mythology, Thor's hammer, Mjölnir, symbolizes protection, strength, and fertility; it was considered a symbol against chaos and a consecration mark. The glass beads from Haithabu are considered a special historical craft, as the town was an important center of glass bead production over 1000 years ago. There, the craft was practiced at a high level of quality, employing specialized techniques such as the production of artistic millefiori beads and the blowing of gold and silver foil, which made the settlement an important trading center for this high-quality jewelry.
