Geography of Middle-earth
The Geography of Middle-earth encompasses the physical, political, and moral geography of J. R. R. Tolkien's fictional world of Middle-earth, strictly a continent on the planet of Arda but widely taken to mean the physical world, and Eä, all of creation, as well as all of his writings about it. Arda was created as a flat world, incorporating a Western continent, Aman, which became the home of the godlike Valar, as well as Middle-earth. At the end of the First Age, the Western part of Middle-earth, Beleriand, was drowned in the War of Wrath. In the Second Age, a large island, Númenor, was created in the Great Sea, Belegaer, between Aman and Middle-earth; it was destroyed in a cataclysm at the end of the Second Age, in which Arda was remade as a spherical world, and Aman was removed so that Men could not reach it.
In The Lord of the Rings, Middle-earth at the end of the Third Age is described as having free peoples, namely Men, Hobbits and Dwarves, in the West, opposed to peoples under the control of the Dark Lord Sauron in the East. Some commentators have seen this as implying a moral geography of Middle-earth.
Cosmology
Tolkien's Middle-earth was part of his created world of Arda. It was a flat world surrounded by ocean. It included the Undying Lands of Aman and Eressëa, which were all part of the wider creation, Eä. Aman and Middle-earth were separated from each other by the Great Sea Belegaer, analogous to the Atlantic Ocean. The western continent, Aman, was the home of the Valar, and the Elves called the Eldar.Initially, the western part of Middle-earth was the subcontinent Beleriand; it was engulfed by the ocean at the end of the First Age.
After the destruction of Númenor at the end of the Second Age, Arda was remade as a round world, and the Undying Lands were removed from Arda so that Men could not reach them. The Elves could go there only by the Straight Road and in ships capable of passing out of the sphere of the earth. Tolkien then equated Arda, consisting of both Middle-earth's planet and the heavenly Aman, with the Solar System, the Sun and Moon being celestial objects in their own right, no longer orbiting the Earth.
Physical geography
The events of The Hobbit and The Lord of the Rings take place in the north-west of the continent of Middle-earth. Both quests begin in The Shire, travel east through the wilds of Eriador to Rivendell and then across the Misty Mountains, involve further travels in the lands of Rhovanion or Wilderland to the east of those mountains, and return home to The Shire.Beleriand, Lindon
The extreme west of Middle-earth in the First Age was Beleriand. It was largely destroyed in the cataclysm of the War of Wrath, leaving only a remnant coastal plain, Lindon, just to the west of the Ered Luin. The cataclysm divided Ered Luin and Lindon by the newly-created Gulf of Lune; the northern part was Forlindon, the southern Harlindon.Eriador
In the northwest of Middle-earth, Eriador was the region between the Ered Luin and the Misty Mountains. In the Second Age, the northern kingdom of Arnor occupied much of the region. After its collapse, much of Eriador became wild. In the Third Age, a small part of the region was occupied by hobbits to form the Shire. To the northwest lay Lake Evendim, once called Nenuial by the Elves. A remnant of the ancient forest of Eriador survived throughout the Third Age just to the east of the Shire as the Old Forest, the domain of Tom Bombadil. Northeast of there is Bree, the only place where hobbits and Men live in the same villages. Further east from there is the hill of Weathertop, the hill with the ancient fortress of Amon Sul, and then Rivendell, the home of Elrond. South from there is the ancient land of Hollin, once the elvish land of Eregion where the Rings of Power were forged.At the Grey Havens, on the Gulf of Lune, Cirdan built the ships in which the Elves departed from Middle-earth to Valinor.
Misty Mountains
The Misty Mountains were thrown up by the Dark Lord Melkor in the First Age to impede Oromë, one of the Valar who often rode across Middle-earth hunting. The Dwarf-realm of Moria was built in the First Age beneath the midpoint of the mountain range. The two major passes across the mountains were the High Pass or Pass of Imladris near Rivendell, with a higher and a lower route, and the all-year Redhorn Pass further south near Moria.Rhovanion
East of the Misty Mountains, Anduin or the Great River flows southwards, with the forest of Mirkwood to its east. On its west bank opposite the southern end of Mirkwood is the elvish land of Lothlorien. Further south, backing on to the Misty Mountains, lies the forest of Fangorn, home of the tree-giants, the ents. In a valley at the southern end of the Misty Mountains is Isengard, home to the wizard Saruman.Lands to the south
Just to the south of both Fangorn and Isengard is the wide grassy land of the Riders of Rohan, who provide cavalry to its southerly neighbour, Gondor. The River Anduin passes the hills of Emyn Muil and the enormous rock statues of the Argonath, flows through the dangerous rapids of Sarn Gebir, and over the Falls of Rauros into Gondor. Gondor's border with Rohan is the Ered Nimrais, the White Mountains, which run east-west from the sea to a point near the Anduin; at that point is Gondor's capital city, Minas Tirith.Across the river to the east is the land of Mordor. It is bordered to the north by the Ered Lithui, the Ash Mountains; to the west by the Ephel Duath, the Mountains of Shadow. Between those two ranges, at Mordor's northwest tip, are the Black Gates of the Morannon. In the angle between the two ranges is the volcanic Plateau of Gorgoroth, with the tall volcano of Orodruin or Mount Doom, where the Dark Lord Sauron forged the One Ring, at its centre. To the mountain's east is Sauron's Dark Tower, Barad-dur.
To the south of Gondor and Mordor lie Harad and Khand. North of Mordor lies the Sea of Rhûn, home to the Easterlings. North of that lie the Iron Hills of Dain's dwarves; between those and Mirkwood is Erebor, the Lonely Mountain, once home to Smaug the dragon, and afterwards to Thorin's dwarves.
The lands to the east of Rhûn and to the south and east of Harad are not described in the stories.
Political geography
At the end of the Third Age, much of the northwest of Middle-earth is wild, with traces here and there of ruined cities and fortresses from earlier civilisations among the mountains, rivers, forests, hills, plains and marshes. The major nations that appear in The Lord of the Rings are Rohan and Gondor on the side of the Free Peoples, and Mordor and its ally Harad on the side of the Dark Lord. Gondor, once extremely powerful, is by that time much reduced in its reach, and has lost control of Ithilien and South Gondor.The Easterlings from the region of Rhûn, barely described, contribute a substantial army to Mordor's side.
Forgotten by most of the rest of the world is the Shire, a small region in the northwest of Middle-earth inhabited by hobbits amidst the abandoned lands of Eriador.
Moral geography
With his "Southrons" from Harad, Tolkien had – in the view of John Magoun, writing in the J.R.R. Tolkien Encyclopedia – constructed a "fully expressed moral geography", from the hobbits' home in the Northwest, evil in the East, and "imperial sophistication and decadence" in the South. Magoun explains that Gondor is both virtuous, being West, and has problems, being South; Mordor in the Southeast is hellish, while Harad in the extreme South "regresses into hot savagery".Other scholars such as Walter Scheps and Isabel G. MacCaffrey have noted Middle-earth's "spatial cum moral dimensions", though not identically with Magoun's interpretation. In their view, North and West are generally good, South and East evil. That places the Shire and the elves' Grey Havens in the Northwest as certainly good, and Mordor in the Southeast as certainly Evil; Gondor in the Southwest is in their view morally ambivalent, matching the characters of both Boromir and Denethor. They observe further that the Shire's four quadrants or "Farthings" serve as a "microcosm" of the moral geography of Middle-earth as a whole: thus, the evil Black Riders appear first in the Eastfarthing, while the once good but corrupted Saruman's men arrive in the Southfarthing.
Origins
Some features of Middle-earth can be traced to literary sources or real-world places. The Misty Mountains derive from the Poetic Edda, where the protagonist in the Skírnismál notes that his quest will involve misty mountains peopled with orcs and giants, while the character of the mountains were partly inspired by Tolkien's travels in the Swiss Alps in 1911.Mirkwood is based on Myrkviðr, the romantic vision of the dark forests of the North.
Númenor echoes the mythical Atlantis described by Plato.
