Morgoth Bauglir ([ˈmɔrɡɔθ ˈbau̯ɡlir]; originally Melkor [ˈmɛlkor]) is a character, one of the godlike Valar, from Tolkien's legendarium. He is the main antagonist of The Silmarillion, The Children of Húrin, Beren and Lúthien, and The Fall of Gondolin. Melkor is the most powerful of the Valar but he turns to darkness and is renamed Morgoth, the primary antagonist of Arda. All evil in the world of Middle-earth ultimately stems from him. One of the Maiar of Aulë betrays his kind and becomes Morgoth's principal lieutenant and successor, Sauron. Melkor has been interpreted as analogous to Satan, once the greatest of all God's angels, Lucifer, but fallen through pride; he rebels against his creator. Morgoth has been likened, too, to John Milton's fallen angel in Paradise Lost, again a Satan-figure. Tom Shippey has written that The Silmarillion maps the Book of Genesis with its creation and its fall, even Melkor having begun with good intentions. Marjorie Burns has commented that Tolkien used the Norse god Odin to create aspects of several characters, the wizard Gandalf getting some of his good characteristics, while Morgoth gets his destructiveness, malevolence, and deceit. Verlyn Flieger writes that the central temptation is the desire to possess, something that ironically afflicts two of the greatest figures in the legendarium, Melkor and Fëanor. Source: Wikipedia (en)
