Therefore Morgoth came, climbing slowly from his subterranean throne, and the rumour of his feet was like thunder underground. And he issued forth clad in black armour; and he stood before the King like a tower, iron-crowned, and his vast shield, sable on-blazoned, cast a shadow over him like a stormcloud. But Fingolfin gleamed beneath it as a star; for his mail was overlaid with silver, and his blue shield was set with crystals; and he drew his sword Ringil, that glittered like ice.
Then Morgoth hurled aloft Grond, the Hammer of the Underworld, and swung it down like a bolt of thunder. But Fingolfin sprang aside, and Grond rent a mighty pit in the earth, whence smoke and fire darted. Many times Morgoth essayed to smite him, and each time Fingolfin leaped away, as a ëlightning shoots from under a dark cloud; and he wounded Morgoth with seven wounds, and seven times Morgoth gave a cry of anguish, whereat the hosts of Angband fell upon their faces in dismay, and the cries echoed in the Northlands.
But at the last the King grew weary, and Morgoth bore down his shield upon hint Thrice he was crushed to his knees, and thrice arose again and bore up his broken shield and stricken helm. But the earth was all rent and pitted about him, and he stumbled and fell backward before the feet of Morgoth; and Morgoth set his left foot upon his neck, and the weight of it was like a fallen hill.
