“If the map doesn’t agree with the ground the map is wrong”*…
Maps from hundreds of years ago can be surprisingly accurate… or they can just be really, really wrong. Weird maps from history invent lands wholesale, distort entire continents, or attempt to explain magnetism planet-wide. Sometimes the mistakes had a surprising amount of staying power, too, getting passed from map to map over the course of years while there was little chance to independently verify…
Gerardus Mercator, creator of everyone’s favorite map projection, didn’t know what the north pole looked like. No one in his time really did. But they knew that magnetic compasses always pointed north, and so a theory developed: the north pole was marked by a giant magnetic black-rock island.
He quotes a description of the pole in a letter: “In the midst of the four countries is a Whirl-pool, into which there empty these four indrawing Seas which divide the North. And the water rushes round and descends into the Earth just as if one were pouring it through a filter funnel. It is four degrees wide on every side of the Pole, that is to say eight degrees altogether. Except that right under the Pole there lies a bare Rock in the midst of the Sea. Its circumference is almost 33 French miles, and it is all of magnetic Stone (…) This is word for word everything that I copied out of this author [Jacobus Cnoyen] years ago.”
Mercator was not the first or only mapmaker to show the pole as Rupes Nigra, and the concept also tied into fiction and mythology for a while. The idea eventually died out, but people explored the Arctic in hopes of finding a passage through the pole’s seas for years before the pole was actually explored in the 1900s…

As we find our way, we might spare a thought for Thomas Doughty; he was beheaded on this date in 1578. A nobleman, soldier, scholar, and personal secretary of Christopher Hatton, Doughty befriended explorer and state-sponsored pirate Francis Drake, then sailed with him on a 1577 voyage to raid Spanish treasure fleets– a journey that ended for Doughty in a shipboard trial for treason and witchcraft, and his execution.
Although some scholars doubt the validity of the charges of treason, and question Drake’s authority to try and execute Doughty, the incident set an important precedent: according to a history of the English Navy, To Rule the Waves: How the British Navy Shaped the Modern World by Arthur L. Herman, Doughty’s execution established the idea that a ship’s captain was its absolute ruler, regardless of the rank or social class of its passengers.

At first, the new website for the collection of MIT’s influential Center for Advanced Visual Studies (CAVS) seems like a straightforward web page. But as it scrolls down, through the introductory text and into randomly selected works from the archive, it becomes clear that the content is warping into three dimensional space, and branching into spiraling trees of related work, organized by creator and medium — an experience designed to evoke the sensation of wandering through the center’s physical archive.
“Someone might be coming in to do research on environmental sculpture, and then they see all these images on, I don’t know, holography, and then they’d say ‘oh, I really want to check that out,’” said Jeremy Grubman, an MIT archivist who spearheaded the project. “So I wanted to find a way to produce that in a digital space, to produce that concept of serendipitous browsing.”
50 years of art across three-dimensional space; as Jon Christian explains, “This MIT archive will be your trippiest scrolling experience today.”

As we prepare for pleasant surprises, we might send cartographically-correct birthday greetings to Gerardus Mercator; he was born on this date in 1512. The most renown cartographer of his time, he created a world map based on a new projection– the Mercator Projection— which represented sailing courses of constant bearing as straight lines, an approach still employed in nautical charts used for navigation.
While he was most esteemed as the foremost geographer of his day, Mercator was also an accomplished engraver, calligrapher and maker of globes and scientific instruments. And he studied theology, philosophy, history, mathematics, and magnetism.
“Here too it’s masquerade, I find”*…
Is confusion a good way to encourage safer driving? That seems to be the idea behind a new traffic calming ploy in Cambridge, England. The city reopened a remodeled street last week featuring what appears, at first, to be a roundabout. Look carefully, however, and you’ll notice that it isn’t a roundabout at all. It’s simply a circle of bricks laid into the street and adjoining sidewalk. It’s practical function is essentially nothing.
Or is it? The city’s thinking is that drivers will instinctively slow down when they approach this ghost roundabout. When they get closer, they will realize they’re actually on a normal street, and accelerate—but in the meantime they will have slowed down and watched the road more carefully on what could be a potentially dangerous corner.
The plan is interesting, if strangely devious, but it hasn’t received the warmest of welcomes from locals…
And … the whole thing is just a little eerie. There’s something unnervingly contemporary about road markings that seek to control drivers specifically through confusion and misinformation. The roundel essentially attempts to undermine drivers’ ability to tell what is real and what is false. It then uses their perplexity to enforce more submissive, hesitant behavior. In a contemporary scene where the concept of “post-truth” has become so ubiquitous that it’s moved from buzzword to cliché, it seems that even road planners are now tapping into the trend for misinformation…

As we prepare to circle, we might spare a cartographically-correct thought for Gerardus Mercator; he died on this date in 1594. The most renown cartographer of his time, he created a world map based on a new projection– the Mercator Projection— which represented sailing courses of constant bearing as straight lines, an approach still employed in nautical charts used for navigation.
While he was most esteemed as the foremost geographer of his day, Mercator was also an accomplished engraver, calligrapher and maker of globes and scientific instruments. And he studied theology, philosophy, history, mathematics, and magnetism.

Across the board, the Mercator projection of the Earth—which has been our baseline for world maps since the 16th century—skews the actual size of countries so they look bigger (and therefore, more important than they are) when they fall within the middle of the Northern Hemisphere. It’s not just bad design, it has real geopolitical implications. For example, in most people’s minds, Greenland is a much larger country than Australia. But the reality is that Australia dwarfs Greenland. Likewise, you probably think Africa and North America are roughly the same size, but Africa can swallow all of North America and Greenland with room for all of Western Europe to spare. And so on… [To redress misperception] James Talmage and Damon Maneice created The True Size. The web app lets you drag-and-drop different countries on a world map and see how they shrink or grow on a standard Mercator Projection map. It’s a simple tool, but an eye-opening one that can be quickly used to show just how skewed our maps really are…

As we ponder perspective, we might might spare a thought for Eratosthenes of Cyrene; he may have died on this date in 194 or 195 BC. (His exact birth and death dates are lost, so this is as good a day as any to celebrate him.) A mathematician, geographer, poet, astronomer, music theorist, and Chief Librarian at Alexandria, Eratosthenes is probably best remembered as the first person to calculate the circumference of the Earth (which he did remarkably accurately), to calculate the tilt of the Earth’s axis, and to calculate the distance from the Earth to the Sun (which, again, he did very accurately); and he created the Leap Day.
In his three-volume work Geography (Geographika), Eratosthenes described and mapped his entire known world, dividing the Earth into five climate zones: two freezing zones around the pole, two temperate zones, and a zone encompassing the equator and the tropics. He placed grids of overlapping lines over the surface of the Earth, using parallels and meridians to link together every place in the world– in the process, coining terminology still in use… He had invented the discipline of Geography.
