Valknut.
From my seria "Good Signs".
The valknut (coined from Old Norse valr, "slain warriors" and knut, "knot") is a symbol consisting of three interlocked triangles. It appears on a variety of objects from the archaeological record of the ancient Germanic peoples. The compound noun valknut is from the modern era. The term used for the symbol during its historical employment is unknown.
Scholars have proposed a variety of explanations for the symbol, sometimes associating it with the god Odin, and it has been compared to the three-horned symbol found on the 9th-century Snoldelev Stone, to which it may be related.[1] The valknut receives sporadic use in modern popular culture and is again associated with Germanic paganism by way of its modern-day revival, Heathenry.
