The sword of Fingolfin, said to have glittered like blue ice. With it he wounded Morgoth in single combat after the Dagor Bragollach. The name comes from ring, meaning 'cold', and refers to the sword's cold and icy blade. Ringil was also an old name for the northern of the two Lamps of the Valar (more usually called Illuin), so named because it stood on a vast pillar of ice, and it may be that Fingolfin chose this name for his sword in memory of the fallen Lamp.
