Detail from Stora Hammars I shows a man lying on his belly with another man using a weapon on his back, a Valknut, and two eagles, one of which is held by a man to the right.
The valknut is a symbol consisting of three interlocked triangles and appears on various Germanic objects. A number of theories have been proposed for its significance. The name valknut is an unattested modern invention used to describe the symbol and was not used contemporaneously when the symbol was used. The valknut has been compared to the three-horned symbol found on the 9th century Snoldelev Stone and may be related to it.
