The historically attested instances of the symbol appear in two traditional, topologically distinct, forms. The symbol appears in unicursal form, topologically a trefoil knot also seen in the triquetra. This unicursal form is found, for example, on the 7th century Tängelgårda stone on the island of Gotland, Sweden. The symbol also appears in tricursal form, consisting of three linked triangles, topologically equivalent to the Borromean rings. This tricursal form can be seen on one of the Lärbro stones, also on Gotland, Sweden, as well as upon a ring found in the River Nene in England, and on a bedpost found within the 834 Oseberg ship burial from Slagen, Norway. Although other forms are topologically possible, these are the only attested forms found so far.
This intrictely designed unicursal Valknut contains 3 duets of worm, entangled in each other in a knotwork desgin, as well as 6 triquetras placed on the visible corners of each triangle.
