The legendary Middle-earth is not a distant planet, but our own ancient history
We often imagine fantasy worlds as alien realms in far-off galaxies. However, J.R.R. Tolkien’s Middle-earth is explicitly described as our own Earth, set in a deeply remote, imagined prehistoric era. It is a reimagining of the very ground we walk on, hidden beneath layers of myth and lost ages.
For Tolkien, Middle-earth was not a separate planet but the 'oecumene'—the inhabited world—during a mythical period of the Earth's past. He viewed his legendarium as an 'imagined prehistory' of our own planet, specifically focusing on the northwest region of the Old World. While the geography was devised 'dramatically' rather than through geology, Tolkien anchored his fiction in real-world coordinates. He famously placed Hobbiton at the same latitude as Oxford, with Minas Tirith 600 miles south, near the latitude of Florence.
The terminology itself draws from deep linguistic roots. The name 'Middle-earth' is a derivative of the Old English 'middangeard' and the Old Norse 'Miðgarðr,' terms that historically referred to the realm of humans. Tolkien’s fascination with these roots began during his studies of Old English fragments in 1913–1914, such as the poem 'Crist I' by Cynewulf. He used these ancient linguistic structures to create a sense of 'literary credibility,' making the fantastical elements feel like a recovered, albeit glorified, memory of human history.
This world, known technically as Arda, underwent massive physical transformations. Originally envisioned with a flat Earth cosmology where stars and the sun revolved around a disc, the legendarium describes a catastrophic transition known as the Akallabêth, which shifted the world to a spherical paradigm. This era of change eventually led to the Third Age, ending approximately 6,000 years ago, leaving a world where the magical races—Elves, Dwarves, and Ents—had largely faded, leaving only Men to inhabit the planet.
