Valknut

The valknut is a symbol consisting of three interlocked triangles. It appears on various Norse artifacts, including the Tängelgårda stone from Gotland, Sweden. The name 'valknut' is a modern Norwegian compound meaning 'knot of those fallen in battle' (valr = the slain, knut = knot). The symbol is associated with the god Odin and with death in battle. Its exact meaning in the Viking Age is debated among scholars, but it is commonly interpreted as a symbol of Odin's power over life and death.

The valknut appears on Norse artifacts from approximately the 5th–11th centuries CE.
