Melkor in the context of "Evil in Middle-earth"

J. R. R. Tolkien built a process of decline and fall in Middle-earth into both The Silmarillion and The Lord of the Rings.

The pattern is expressed in several ways, including the splintering of the light provided by the Creator, Eru Iluvatar, into progressively smaller parts; the fragmentation of languages and peoples, especially the Elves, who are split into many groups; the successive falls, starting with that of the angelic spirit Melkor, and followed by the destruction of the two Lamps of Middle-earth and then of the Two Trees of Valinor, the destruction of Gondolin, and the cataclysmic fall of Númenor.

The Old Straight Road, the Straight Road, the Lost Road, or the Lost Straight Road, is J. R. R. Tolkien's conception, in his fantasy world of Arda, that his Elves are able to sail to the earthly paradise of Valinor, realm of the godlike Valar. The tale is mentioned in The Silmarillion and in The Lord of the Rings, and documented in The Lost Road and Other Writings. The Elves are immortal, but may grow weary of the world, and then sail across the Great Sea to reach Valinor. The men of Númenor are persuaded by Sauron, servant of the first Dark Lord Melkor, to attack Valinor to get the immortality they feel should be theirs. The Valar ask for help from the creator, Eru Ilúvatar. He destroys Númenor and its army, in the process reshaping Arda into a sphere, and separating it and its continent of Middle-earth from Valinor so that men can no longer reach it. Elves can still set sail from the shores of Middle-earth in ships, bound for Valinor: they sail into the Uttermost West, following the Old Straight Road.

Scholars have noted the importance of the theme to Tolkien, as he revisited it repeatedly. His early mention of the Straight Road as being a level bridge recalls Bifröst, the bridge between the earthly Midgard and the gods' home of Asgard in Norse mythology. Other possible inspirations for the theme include a literary crux in Beowulf in the shape of the character Scyld Scefing. He arrives in the world as a baby in a boat filled with gifts, and he departs from it in a ship-burial, with the odd feature that the ship is not set on fire, as in the typical Viking ritual. The scholar Tom Shippey suggests that Tolkien may have felt that Scyld is being sent back to the gods across the Western sea via a kind of Straight Road, and that Tolkien perhaps created his Valar and their home Valinor to explain that gap in Beowulf. His poem "A Walking Song", which occurs in different versions at the start and end of The Lord of the Rings, also alludes to the theme.

The fictional cosmology of J. R. R. Tolkien's legendarium combines aspects of Christian theology and metaphysics with pre-modern cosmological concepts in the flat Earth paradigm, along with the modern spherical Earth view of the Solar System.

The created world, Eä, includes the planet Arda, corresponding to the Earth. It is created flat, with the dwelling of the godlike Valar at its centre. When this is marred by the evil Vala Melkor, the world is reshaped, losing its perfect symmetry, and the Valar move to Valinor, but the Elves can still sail there from Middle-earth. When Men try to go there, hoping for immortality, Valinor and its continent of Aman are removed from Arda, which is reshaped as a round world. Scholars have compared the implied cosmology with that of Tolkien's religion, Catholicism, and of medieval poetry such as Pearl or Dante's Paradiso, where there are three parts, Earth, Purgatory or the Earthly Paradise, and Heaven or the Celestial Paradise. Scholars have debated the nature of evil in Middle-earth, arguing whether it is the absence of good (the Boethian position) or equally as powerful as good (the Manichaean view).

J. R. R. Tolkien, a devout Roman Catholic, embodied Christianity in his legendarium, including The Lord of the Rings. Light is a prominent motif in Christianity: it is the first thing created by God in the Book of Genesis, it symbolizes God's grace and blessings elsewhere in the Old Testament, and it is closely associated with both Jesus and humanity itself in the Gospel of John in the New Testament.

In The Silmarillion, light is similarly important. It appears early on in the Years of the Lamps, with two enormous lamps atop mountain-sized pillars to light the world of Arda. When these are destroyed by the Dark Lord Melkor, they are replaced by the Two Trees of Valinor, which provide light for the new home of the Valar. When these too are destroyed, the Valar use their last fruit and their last flower to create the Sun and the Moon. A little of the light of the Two Trees is captured in the Silmarils, the crafted jewels that give the book its name. These are coveted by the Dark Lord, provoking war and the destruction of much of the world of Elves, Men, and Dwarves. A survivor, Eärendil, sails across the Great Sea to ask the Valar to intervene; they expel the Dark Lord, and Eärendil and his ship Vingilot sail the heavens as the Morning Star.
