Why the south of Westeros is the north of Ireland

As Game of Thrones ends, a revealing resolution to its perplexing geography.

  • The fantasy world of Game of Thrones was inspired by real places and events.
  • But the map of Westeros is a good example of the perplexing relation between fantasy and reality.
  • Like Britain, it has a Wall in the North, but the map only really clicks into place if you add Ireland.

Warning: if you haven't caught up, mild spoiler ahead.

"Hell is other people talking about Game of Thrones," writes Arwa Mahdawi in The Guardian this week. A few days more, and the eighth and final season of the show she dubs "densely plotted goblin porn" — clearly, she's not a fan — will be over.

Meanwhile, hell is hard to avoid. When it comes to following GoT, I'm on Team Arwa (a.k.a. Team Stewart) but even we have heard rumors about a sudden bout of genocidal mania, and Daenerys perhaps no longer being such a good baby name.

Fortunately for map nerds, GoT's dense plotting also extends to its topography. Just like the series' peoples, protagonists and events — often borrowed from actual history, then slightly altered — its fictional map is more than loosely based on ours.

Maps to frame fantasy

Fantasy locations have been a literary device at least since Plato spun his stories about Atlantis, back in the 4th century BC. From Plato only a description of the island survives, more recent tales of fictional geography came with a map: Thomas More's Utopia, Jonathan Swift's Lilliput (and other islands visited by Gulliver), and Robert Louis Stevenson's Treasure Island.

The watershed fantasy map, the one that spawned a thousand imitations, is the map of Middle-Earth, created by J.R.R. Tolkien himself (from the 1920s to the 1940s): as the endpapers to the Lord of the Rings trilogy, they framed the wanderings of the Fellowship, the movements of armies and heroes, and the deep history underlying the narrative.

"I wisely started with a map and made the story fit," Tolkien once quipped. George R.R. Martin did it the other way around: he envisaged the opening scene of the first book of A Song of Ice and Fire (the book series adapted as GoT) and built the tale — and the world around it — from there.

Not just a badly drawn Britain

Only then did he take on the mantle of the First Cartographer, and it's his hand-drawn maps that appear in the books. Another similarity with Tolkien, whose fantasy world was inspired by real geography was that Martin also drew his world with one eye on the map of Europe, and especially the British Isles.

Most of the action, in the books and the series, takes place on the continent of Westeros (there is a whole Known World out there as well). There's an obvious parallel with Great Britain in the Wall in the North: at 700 feet high and 300 miles long, it is a clear extrapolation of Hadrian's Wall (a mere 73 miles long, and never higher than 20 feet).

Westeros is much bigger than Britain, though: about 3,000 miles from the Wall to the south coast, about six times the distance from Aberdeen to London. But Westeros is not just a badly drawn Britain, nor a mirrored version of its land mass (two popular theories). Things click into place — literally — if you do the following:

Take Ireland, turn it on its head, inflate it by about a third, and stick it to Britain's bottom (via a new land bridge called The Neck). And hey presto, there's Westeros.

Britain and Ireland, joined at the - ahem - south coast

In fact, Martin admitted as much at the 2014 Comic–Con: "If you want to know where a lot of fantasy maps come from, take a look at any map in the front of your favorite fantasy book and turn it upside down. Westeros began as upside-down Ireland. You can see the Fingers at the Dingle Peninsula."

This has some implications for the (presumed) parallels between locations in Westeros on one side, and Britain/Ireland on the other. For instance, King's Landing, the capital of Westeros, corresponds to Galway rather than London.

But such correspondences are futile. Each borrowing from actual history and geography is given a little twist, so people can argue until they're blue in the face whether the Red Wedding was inspired by the St. Bartholomew Day's Massacre or by the Black Dinner, whether the Dothraki are the Huns or the Mongols, and if Winterfell is Manchester or Leeds.

For some, King's Landing is reminiscent of old Constantinople. In the TV series, the old walled cities of Mdina (Malta) and Dubrovnik (Croatia) stand in for the capital. And Martin himself dreamt up the teeming city remembering the view of Staten Island from his childhood home in Bayonne, New Jersey.

For some, that tension with "real" history and geography adds a layer of enjoyment to GoT. Team Arwa can feign interest in a cartographic discovery that hardcore fans have made years ago, and will be happy only when the last dragon has finally landed.

Two MIT students just solved Richard Feynman’s famed physics puzzle

Richard Feynman once asked a silly question. Two MIT students just answered it.

Surprising Science

Here's a fun experiment to try. Go to your pantry and see if you have a box of spaghetti. If you do, take out a noodle. Grab both ends of it and bend it until it breaks in half. How many pieces did it break into? If you got two large pieces and at least one small piece you're not alone.

Our ‘little brain’ turns out to be pretty big

The multifaceted cerebellum is large — it's just tightly folded.

Image source: Sereno, et al
Mind & Brain
  • A powerful MRI combined with modeling software results in a totally new view of the human cerebellum.
  • The so-called 'little brain' is nearly 80% the size of the cerebral cortex when it's unfolded.
  • This part of the brain is associated with a lot of things, and a new virtual map is suitably chaotic and complex.

Just under our brain's cortex and close to our brain stem sits the cerebellum, also known as the "little brain." It's an organ many animals have, and we're still learning what it does in humans. It's long been thought to be involved in sensory input and motor control, but recent studies suggests it also plays a role in a lot of other things, including emotion, thought, and pain. After all, about half of the brain's neurons reside there. But it's so small. Except it's not, according to a new study from San Diego State University (SDSU) published in PNAS (Proceedings of the National Academy of Sciences).

A neural crêpe

A new imaging study led by psychology professor and cognitive neuroscientist Martin Sereno of the SDSU MRI Imaging Center reveals that the cerebellum is actually an intricately folded organ that has a surface area equal in size to 78 percent of the cerebral cortex. Sereno, a pioneer in MRI brain imaging, collaborated with other experts from the U.K., Canada, and the Netherlands.

So what does it look like? Unfolded, the cerebellum is reminiscent of a crêpe, according to Sereno, about four inches wide and three feet long.

The team didn't physically unfold a cerebellum in their research. Instead, they worked with brain scans from a 9.4 Tesla MRI machine, and virtually unfolded and mapped the organ. Custom software was developed for the project, based on the open-source FreeSurfer app developed by Sereno and others. Their model allowed the scientists to unpack the virtual cerebellum down to each individual fold, or "folia."

A complicated map

Sereno tells SDSU NewsCenter that "Until now we only had crude models of what it looked like. We now have a complete map or surface representation of the cerebellum, much like cities, counties, and states."

That map is a bit surprising, too, in that regions associated with different functions are scattered across the organ in peculiar ways, unlike the cortex where it's all pretty orderly. "You get a little chunk of the lip, next to a chunk of the shoulder or face, like jumbled puzzle pieces," says Sereno. This may have to do with the fact that when the cerebellum is folded, its elements line up differently than they do when the organ is unfolded.

It seems the folded structure of the cerebellum is a configuration that facilitates access to information coming from places all over the body. Sereno says, "Now that we have the first high resolution base map of the human cerebellum, there are many possibilities for researchers to start filling in what is certain to be a complex quilt of inputs, from many different parts of the cerebral cortex in more detail than ever before."

This makes sense if the cerebellum is involved in highly complex, advanced cognitive functions, such as handling language or performing abstract reasoning as scientists suspect. "When you think of the cognition required to write a scientific paper or explain a concept," says Sereno, "you have to pull in information from many different sources. And that's just how the cerebellum is set up."

Bigger and bigger

The study also suggests that the large size of their virtual human cerebellum is likely to be related to the sheer number of tasks with which the organ is involved in the complex human brain. The macaque cerebellum that the team analyzed, for example, amounts to just 30 percent the size of the animal's cortex.

"The fact that [the cerebellum] has such a large surface area speaks to the evolution of distinctively human behaviors and cognition," says Sereno. "It has expanded so much that the folding patterns are very complex."

As the study says, "Rather than coordinating sensory signals to execute expert physical movements, parts of the cerebellum may have been extended in humans to help coordinate fictive 'conceptual movements,' such as rapidly mentally rearranging a movement plan — or, in the fullness of time, perhaps even a mathematical equation."

Sereno concludes, "The 'little brain' is quite the jack of all trades. Mapping the cerebellum will be an interesting new frontier for the next decade."
