Although other forms are topologically possible, these are the only attested forms found so far. This tricursal form can be seen on one of the Stora Hammars stones, as well as upon the Nene River Ring, and on the Oseberg ship bed post. The symbol also appears in tricursal form, consisting of three linked triangles, topologically equivalent to the Borromean rings. This unicursal form is found, for example, on the Tängelgårda stone. The symbol appears in unicursal form, topologically a trefoil knot also seen in the triquetra. The historically attested instances of the symbol appear in two traditional, topologically distinct, forms. Additionally, the valknut appears prominently on two picture stones from Gotland, Sweden: the Stora Hammars I stone and the Tängelgårda stone. A wooden bed in the Viking Age Oseberg Ship buried near Tønsberg, Norway features a carving of the symbol on an ornately stylized bedpost and the Oseberg tapestry fragments, a partially preserved tapestry found within the ship burial, also features the symbol. The symbol is prominently featured on the Nene River Ring, an Anglo-Saxon gold finger ring dated to around the 8th to 9th centuries. The valknut appears on a wide variety of objects found in areas inhabited by the Germanic peoples. A section of the Stora Hammars I stone in Gotland, Sweden depicts a valknut in a central and predominant position, appearing alongside figures interpreted as Odin with a characteristic spear shunting another figure into a burial mound while a raven is overhead and another man is hanged.
