A Mirkwood appears in several places in
J. R. R. Tolkien's writings, among the numerous forests that play important roles in his storytelling. He used the name Mirkwood in another unfinished work,
The Fall of Arthur. But the name is best known and most prominent in his
Middle-earth legendarium, where it appears as two distinct forests, one in the
First Age in
Beleriand, as described in
The Silmarillion, the other in the
Third Age in Rhovanion, as described in both
The Hobbit and
The Lord of the Rings. He was familiar with Morris's
The House of the Wolfings, naming the book as an influence (for instance on the
Dead Marshes) in a 1960 letter.
The First Age forest in Beleriand In
The Silmarillion, the forested highlands of Dorthonion in the north of Beleriand (in the northwest of Middle-earth) eventually fell under
Morgoth's control and was subjugated by creatures of
Sauron, then Lord of Werewolves. Accordingly, the forest was renamed
Taur-nu-Fuin in
Sindarin, "Forest of Darkness", or "Forest of Nightshade"; Tolkien chose to use the English form "Mirkwood".
Beren becomes the sole survivor of the men who once lived there as subjects of the
Noldor King
Finrod of
Nargothrond. Beren ultimately escapes the terrible forest that even the
Orcs fear to spend time in.
Beleg pursues the captors of
Túrin through this forest in the several accounts of Túrin's tale. Along with the rest of Beleriand, this forest was lost in the cataclysm of the
War of Wrath at the end of the First Age.
The forest in Rhovanion Mirkwood is a vast
temperate broadleaf and mixed forest in the
Middle-earth region of Rhovanion (Wilderland), east of the great river
Anduin. In
The Hobbit, the wizard
Gandalf calls it "the greatest forest of the Northern world." Before it was darkened by evil, it had been called Greenwood the Great. Tolkien
charted Mirkwood in ''Thror's Map
and the Map of Wilderland
, which formed endleaves to The Hobbit''. Within the text, an ink illustration captioned 'The Elvenking's Gate' depicts the entrance to King
Thranduil's kingdom. After the publication of
the maps in
The Lord of the Rings, Tolkien wrote a correction stating "Mirkwood is too small on map it must be 300 miles across" from east to west, but the maps were never altered to reflect this. On the published maps, Mirkwood was up to across; from north to south it stretched about . The
J. R. R. Tolkien Encyclopedia states that it is long and wide. The trees were large and densely packed. In the north they were mainly
oaks, although
beeches predominated in the areas favoured by
Elves. Animals within the forest were described as inedible. The elves of the forest, too, are "black" and hostile, drawing a comparison with
Svartalfheim ("Black elf home") in
Snorri Sturluson's Old Norse
Edda, quite unlike the friendly elves of
Rivendell. Near the end of the
Third Age – the period in which
The Hobbit and
The Lord of the Rings are set – the expansive forest of "Greenwood the Great" was renamed "Mirkwood",
supposedly a translation of an unknown
Westron name. The forest plays little part in
The Lord of the Rings, but is important in
The Hobbit for both atmosphere and plot. The
White Council flushes Sauron out of his forest tower at Dol Guldur, and as he flees to
Mordor his influence in Mirkwood diminishes. Years later,
Gollum, after his release from Mordor, is captured by
Aragorn and brought as a prisoner to Thranduil's realm. Out of pity, they allow him to roam the forest under close guard, but he escapes during an
Orc raid. After the downfall of Sauron, Mirkwood is cleansed by the elf-queen
Galadriel and renamed
Eryn Lasgalen,
Sindarin for "Wood of Greenleaves". Thranduil's son,
Legolas, leaves Mirkwood for
Ithilien. The
wizard Radagast lived at Rhosgobel on the western eaves of Mirkwood, as depicted in the film
The Hobbit: An Unexpected Journey.
Dol Guldur Dol Guldur (
Sindarin: "Hill of Sorcery") was Sauron's stronghold in Mirkwood, before he returned to
Barad-dûr in
Mordor. It is first mentioned (as "the dungeons of the Necromancer") in
The Hobbit. The hill itself, rocky and barren, was the highest point in the southwestern part of the forest. Before Sauron's occupation, it was called Amon Lanc ("Naked Hill"). It lay near the western edge of the forest, across the
Anduin from
Lothlórien. Tolkien suggests that Sauron settled on Dol Guldur as the focus for his rise during the period before the
War of the Ring in part so that he could search for the
One Ring in the
Gladden Fields just up the river. == Literary philology ==
