A form of the Borromean link was used by the Norse people of Scandinavia. The symbol known as `Odin’s triangle’ or the `Walknot’ (meaning knot of the slain).
The symbol is associated with the Norse god Odin. Scenes on picture stones show fallen warriors travelling to the next world by boat or on horseback where they will join others in Odin’s palace `Valhalla’ – the castle of the slain. The Walknot symbol is often placed near these departed heroes. It has also been found carved into a bedpost used in a ship-burial.
