This cast metal crescent amulet belongs to a form commonly referred to as a lunula, a pendant type widely used during the Viking Age (circa 800–1100 AD). Crescent-shaped amulets are known from archaeological finds across Scandinavia and regions connected to Norse trade and settlement. In Norse culture, the crescent is often interpreted as a symbol of lunar power, fertility, protection, and cyclical renewal, reflecting pre-Christian belief systems. Such pendants were worn as personal talismans, suspended from cord or chain, and intended for everyday use. The present example displays a robust cast construction, an integral suspension loop, and a heavily worn surface with deep patination and corrosion consistent with significant age and long-term burial. The simplicity of the design aligns with utilitarian Viking jewelry rather than later medieval decorative forms. While crescent amulets appear in multiple cultures, this example is stylistically and technologically consistent with Viking Age Norse material, making a Viking attribution plausible.
