§ Of the Rings of Power and the Third Age The Silmarillion

The host of Gil-galad and Elendil had the victory, for the might of the Elves was still great in those days, and the Númenóreans were strong and tall, and terrible in their wrath. Against Aeglos the spear of Gil-galad none could stand; and the sword of Elendil filled Orcs and Men with fear, for it shone with the light of the sun and of the moon, and it was named Narsil.
