A loop of rope that has no beginning and no end, it symbolized eternity. The shen also seems to be a symbol of protection. It is often seen being clutched by deities in bird form, Horus the falcon, Mut the vulture. Hovering over Pharaohs head with their wings outstretched in a gesture of protection. The word shen comes from the word "shenu" which means "encircle," and in its elongated form became the cartouche which surrounded the king's name.
