Because of the Electoral College and the way the primary system works in the US, presidential candidates end up spending a disproportionate amount of time is so-called “battleground states” like Pennsylvania, Ohio, and our dysfunctional friend Florida and primary states like Iowa and New Hampshire and less time where most of the US population actually lives (NY, CA, TX, IL, and in cities). The campaign for the National Popular Vote has produced a map that shows where the candidates did campaign events in 2016:
Because of these state winner-take-all statutes, presidential candidates have no reason to pay attention to the issues of concern to voters in states where the statewide outcome is a foregone conclusion. In 2012, as shown on the map, all of the 253 general-election campaign events were in just 12 states, and two-thirds were in just 4 states (Ohio, Florida, Virginia, and Iowa). Thirty-eight states were completely ignored.
And here’s the map for the 2012 election, which is even more extreme:
State winner-take-all statutes adversely affect governance. “Battleground” states receive 7% more federal grants than “spectator” states, twice as many presidential disaster declarations, more Superfund enforcement exemptions, and more No Child Left Behind law exemptions.
Also, because of state winner-take-all statutes, five of our 45 Presidents have come into office without having won the most popular votes nationwide. The 2000 and 2016 elections are the most recent examples of elections in which a second-place candidate won the White House. Near-misses are also common under the current state-by-state winner-take-all method of awarding electoral votes. A shift of 59,393 votes in Ohio in 2004 would have elected John Kerry despite President Bush’s nationwide lead of over 3,000,000 votes.
Today I learned that ZIP Codes do not strictly represent geographic areas but rather “address groups or delivery routes”.
Despite the geographic derivation of most ZIP Codes, the codes themselves do not represent geographic regions; in general, they correspond to address groups or delivery routes. As a consequence, ZIP Code “areas” can overlap, be subsets of each other, or be artificial constructs with no geographic area (such as 095 for mail to the Navy, which is not geographically fixed). In similar fashion, in areas without regular postal routes (rural route areas) or no mail delivery (undeveloped areas), ZIP Codes are not assigned or are based on sparse delivery routes, and hence the boundary between ZIP Code areas is undefined.
The White House has its own ZIP Code (20500), as does the shoe floor of Saks Fifth Avenue in NYC (10022-SHOE). US mail to Santa Claus gets sent to the town of North Pole, Alaska (99705) but in Canada, Santa gets his own postal code (H0H 0H0). And Smokey Bear has his own ZIP Code (20252) because he gets so much mail.
Even though there are different place associations that probably mean more to you as an individual, such as a neighborhood, street, or the block you live on, the zip code is, in many organizations, the geographic unit of choice. It is used to make major decisions for marketing, opening or closing stores, providing services, and making decisions that can have a massive financial impact.
The problem is that zip codes are not a good representation of real human behavior, and when used in data analysis, often mask real, underlying insights, and may ultimately lead to bad outcomes. To understand why this is, we first need to understand a little more about the zip code itself.
For instance, in Miami’s 33139 ZIP Code the difference between the highest median income (as measured in much more granular US Census Block Groups) and lowest median income is over $240,000. So you can imagine it would be difficult to know or even assume anything in general about those residents based on their ZIP Code alone.
Gerry is a typeface where the letterforms are created from heavily gerrymandered Congressional districts. For example, the letter U is the 4th district in Illinois:

Every few seconds, the visualization picks a new satellite to track, allowing you to see the location, height, and speed. The satellites are 300 miles from the surface of the Earth moving at about 17,000 mph.
Part of the appeal of Berann’s depictions of the national parks is that they look fairly realistic while at the same time greatly enhancing the landscapes in a number of ways. The end result is similar to what you might see from the window of a plane, and yet better than any possible real-world view, Patterson says.
Berann made sure all the important features of each park were visible in the scene. Sometimes this required some creative distortion. On the Yosemite National Park panorama below, for instance, Yosemite Valley is widened to allow all the rock formations, waterfalls, and man-made structures to be clearly seen. All of the valley’s iconic natural features are exaggerated, with Half Dome and El Capitan much taller than in real life, and the waterfalls significantly longer.
(As an aside, I got this link from Open Culture, who said they found it via Boing Boing. I clicked through to Boing Boing to see that they’d discovered the link from, uh, kottke.org? Perhaps from this link last year?)
With the 50th anniversary of the first crewed landing on the Moon fast approaching, I thought I’d share one of my favorite views of the Moon walk, a map of where Neil Armstrong and Buzz Aldrin walked on the Moon, superimposed over a baseball field (bigger). The Lunar Module is parked on the pitcher’s mound and you can see where the two astronauts walked, set up cameras, collected samples, and did experiments.
This map easily illustrates something you don’t get from watching video of the Moon walk: just how close the astronauts stayed to the LM and how small an area they covered during their 2 and 1/2 hours on the surface. The crew had spent 75+ hours flying 234,000 miles to the Moon and when they finally got out onto the surface, they barely left the infield! On his longest walk, Armstrong ventured into center field about 200 feet from the mound, not even far enough to reach the warning track in most major league parks. In fact, the length of Armstrong’s walk fell far short of the 363-foot length of the Saturn V rocket that carried him to the Moon and all of their activity could fit neatly into a soccer pitch (bigger):
Astronauts on subsequent missions ventured much further. The Apollo 12 crew ventured 600 feet from the LM on their second walk of the mission. The Apollo 14 crew walked almost a mile. After the Lunar Rover entered the mix, excursions up to 7 miles during EVAs that lasted for more than 7 hours at a time became common.
From National Geographic comes The Atlas of Moons, an interactive reference to all of the major moons in our solar system, from the Earth’s own moon to the Galilean moons of Jupiter to Charon, which forms a binary system with Pluto.
For whatever reason, I wasn’t fully aware that some of Jupiter’s and Saturn’s major moons orbited their planets so quickly — Europa takes 3.6 days to complete an orbit, Io once every 1.8 days, and Mimas speeds around Saturn every 22.6 hours.
In 1587, Urbano Monte made the largest known early map of Earth. The map consists of 60 panels that were meant to be assembled into a planisphere (a circular map that rotates about a central axis) measuring 10 feet across. The David Rumsey Map Center recently acquired a manuscript of Monte’s map and digitally assembled all 60 pieces into the full map (inlined above but click through to zoom/pan).
Of great interest is the attempt Monte makes to make his map not just a geographical tool but to show climate, customs, length of day, distances within regions — in other words, to create a universal scientific planisphere. In his dedication on tavola XL he specifies how to arrange the sheets of the mappamondo and makes it explicit that the whole map was to be stuck on a wooden panel 5 and a half brachia square (3.25m) so that it could be revolved around a central pivot or pin through the north pole.
The individual map panels looked like this:
Of course, once the image is digital you can map it into all sorts of different projections like Mercator or Ortelius oval projection.
At The Paris Review, historian Ted Widmer highlights the work of Emma Willard, pioneering educator and America’s first female mapmaker. Willard began her mapmaking career in the 1820s.
She used every tool available to teach young readers (and especially young women) how to see history in creative new ways. If the available textbooks were tedious (and they were), she would write better ones. If they lacked illustrations, she would provide them. If maps would help, so be it: she would fill in that gap as well. She worked with engravers and printers to get it done. She was finding her way forward in a male-dominated world, with no map to guide her. So she made one herself.
The maps for sale show North America in twelve different snapshots. I say “snapshots” because Willard was such an inventive visual thinker. On the eve of photography, she was thinking hard about how to capture a big story inside a single striking image.
It takes some imagination, but standing before a painting by Hilma af Klint, a sculpture by Bernini, or a cave painting in Chauvet, France draws you back in time in a powerful way: you know you’re standing precisely where those artists stood hundreds or even thousands of years ago, laying paint to surface or chisel to stone. Even experiencing art through prints or photographs leads the mind to consider all the cultural, political, technological, and economic things that were happening when the work was produced. Art is a doorway to past worlds.
Fisk’s maps represent the memory of a mighty river, with thousands of years of course changes compressed into a single image by a clever mapmaker with an artistic eye. Looking at them, you’re invited to imagine the Mississippi as it was during the European exploration of the Americas in the 1500s, during the Cahokia civilization in the 1200s (when this city’s population matched London’s), when the first humans came upon the river more than 12,000 years ago, and even back to before humans, when mammoths, camels, dire wolves, and giant beavers roamed the land and gazed upon the river.
I don’t know if this needs a disclaimer or not, but 20x200 paid me a modest amount to write this blog post for their site but not the post you’re reading now. 20x200 didn’t pay me to write this here post; they didn’t even ask me if I would link to their post from my site. I once wrote a slightly longer (and progressively unhinged) disclaimer for a previous post about 20x200.
Over the past year and a half I’ve been working on a collection of ten maps on planets, moons, and outer space. To name a few, I’ve made an animated map of the seasons on Earth, a map of Mars geology, and a map of everything in the solar system bigger than 10km.
As promised, Lutz has posted the source code for each project to her GitHub account: Mercury topography, asteroid orbits. What a great resource for aspiring data visualization designers. Stay tuned to her site, Twitter, or Tumblr for upcoming installments of the atlas.
This week’s map shows every single star visible from Earth, on the darkest night with the clearest sky. The map also includes all of the brightest galaxies, nebulae, and star clusters from W.H. Finlay’s Concise Catalog of Deep-sky Objects. I illustrated the familiar Western star patterns — or asterisms — in blue and gold, as well as the scientific constellation boundaries in red.
Update: Holy moly, I think Lutz’s Topographic Map of Mars might be her most beautiful one yet.
Update: I couldn’t keep up with all of Lutz’s additions to her atlas. You can check out all of the installments in the archive, including the last part (for now), The Geology of the Moon.
Chang’e-4 and Yutu-2 are now past their prime mission and are in their extended mission phases. Their companion SmallSat, Longjiang-2, will crash into the Moon on 31 July to bring its mission to an intentional end. Parker Solar Probe is near aphelion as of 1 July and will reach its third death-defying solar perihelion on 1 September. BepiColombo completed its near-Earth commissioning phase on 5 April and is now settling into its long-cruise phase. Earlier this year, the ESA-JAXA Mercury mission was racing ahead of Earth on an inside track, but its elliptical orbit has now taken it farther from the Sun than Earth, allowing Earth to catch up. It will return to Earth’s neighborhood in April 2020 for a flyby.
I counted roughly 30 different probes and rovers in operation, most of them gathered around the Moon and Mars. Sure, where’s my jetpack and flying car and all that, but the fact that humanity has more than two dozen robots currently exploring the solar system seems pretty futuristic to me.
Eleanor Lutz is one of my favorite data visualizers (previously) and she’s about ready to drop her new project: An Atlas of Space.
I’m excited to finally share a new design project this week! Over the past year and a half I’ve been working on a collection of ten maps on planets, moons, and outer space. To name a few, I’ve made an animated map of the seasons on Earth, a map of Mars geology, and a map of everything in the solar system bigger than 10km.
Over the next few weeks I want to share each map alongside the open-source Python code and detailed tutorials for recreating the design. All of the astronomy data comes from publicly available sources like NASA and the USGS, so I thought this would be the perfect project for writing design tutorials (which I’ve been meaning to do for a while).
Ahhh, look at those colors! Lutz is going to be posting a new map from the project periodically over the next few weeks so follow her on Tabletop Whale, Twitter, or Tumblr to tune in.
Update: I’m keeping track of the projects that make up the atlas as they are released in updates to this post.
First You Make the Maps is a survey of mapping technology by Elizabeth Della Zazzera showing how, starting at the end of the Middle Ages, better maps facilitated the European discovery of the Americas, the explosion of global trade, the enslavement of Africans, and the colonization by Europeans of much of the world.
While geographically accurate maps had existed before, the Age of Exploration saw the emergence of a sustained tradition of topographic surveying. Maps were being made specifically to guide travelers. Technology progressed quickly through the centuries, helping explorers and traders find their way to new imperial outposts — at least sometimes. On other occasions, hiccups in cartographic reasoning led their users even farther astray.
Not only the coast lines are reversed in this world. Also, the relief is consistently the opposite of reality. So the deepest parts of the oceans are in the Tibetan and Himalayan troughs in the southern part of the Asian Ocean. And the highest peaks, around eleven kilometer, are found in the Mariana Mountains in the west of the continent Pacifica.
Using geological surveys, geo-referenced road network data, and historic maps drawn the from the collections of the Library of Congress and New York Public Library, Miles Zhang made this time lapse video of the development of the street grid of NYC from 1609 (when Henry Hudson first explored the area for the Dutch) to the present day.
The resulting short film presents a series of “cartographic snapshots” of the built-up area at intervals of every 20-30 years in the city’s history. This process highlights the organic spurts of growth and movement that typify New York’s and most cities’ development through time. The result is an abstract representation of urbanism.
For almost the first half of Manhattan’s history, walking was the primary means of transport. This preference was manifested in the shorter distances between residential, industrial, shipping, and commercial areas — and more frequently their overlap. With street systems, the reliance on the foot is manifested in narrower streets widths not designed to accommodate greater width from carriages, trolleys, and later cars. In fact, the average width of secondary arterial streets increased from 30 feet for streets opened between 1624-1664, to 45 feet for streets opened 1664-1811, and then a uniform width of 60 feet for any cross street opened after 1811. Later widenings increased many of these smaller and pre-1811 streets to width between 100 and 130 feet. In other words, moving from the older networks in the south to newer networks in the north, the width of streets and size of blocks generally increases. These new widths might be influenced by growing population size from only 25,000 in the 1770s, to 64,000 by 1811, and 247,000 by 1834, thereby requiring wider streets for expanding population and higher buildings.
These gradual changes in planning reflected increasing reliance on carriages and horse-drawn trolleys instead of walking. Each mode of transport required a different minimum street width and was associated with different speeds.
Oh my, this medieval town generator tool is super fun to play around with. By adjusting parameters like size, color palette, building styles, and which features to include (rivers, coastline, temples), you can make a random ichnographic map of a medieval town or city.
Toy Town is a related tool by the same person that allows you to move through a 3D visualization of a medieval town, a la Minecraft. (Unfortunately, you can’t generate a map in the 2D tool and then fly through it in the 3D tool.)
In it, she introduces a system BuzzFeed developed called cultural cartography.
The question I get most frequently is: How do you make something go viral? The question itself is misplaced; it’s not about the something. It’s about what the people doing the something, reading or watching — what are they thinking? Now, most media companies, when they think about metadata, they think about subjects or formats. It’s about goats, it’s about office pranks, it’s about food, it’s a list or a video or a quiz, it’s 2,000 words long, it’s 15 minutes long, it has 23 embedded tweets or 15 images. Now, that kind of metadata is mildly interesting, but it doesn’t actually get at what really matters. What if, instead of tagging what articles or videos are about, what if we asked: How is it helping our users do a real job in their lives?
Last year, we started a project to formally categorize our content in this way. We called it, “cultural cartography.” It formalized an informal practice that we’ve had for a really long time: don’t just think about the subject matter; think also about, and in fact, primarily about, the job that your content is doing for the reader or the viewer.
Here’s what BuzzFeed’s map of their users’ desires looks like:
But as former BuzzFeed employee Matthew Perpetua notes in a post about pop star Lizzo, content can start to feel formulaic if, you know, you use an actual formula to produce it.
I can’t hear Lizzo’s music without recognizing her cultural cartography savvy. A lot of music can achieve these goals without contrivance, often just as a natural side effect of an artist intuitively making resonant work, but Lizzo’s songs all sound very calculated to me. This is not such a bad thing — her skill in expressing herself in relatable ways is a major talent, and I’ve worked with many people who have this natural skill and hold them in very high regard. (I’m much better at telling people who they are rather than asking you to identify with who I am.) Lizzo has a good voice, and her songs range from “pretty good” to “undeniable banger” but I have mixed feelings about all of it because I know the game being played rather well, and because I’m uncomfortable with this self-consciously audience-pleasing approach to content creation becoming the primary mode of pop culture.
All artists who produce work for a large audience (or aspire to) have a method like cultural cartography, though most likely much less formal and more intuitive than BuzzFeed’s system. Some artists are better than others in disguising their methods.
For almost as long as we’ve had civilization, people have been making data visualizations.1 The availability of paper and screens has exploded their creation in the last few hundred years, but the earliest visualizations were made from physical objects. This list contains more than 300 examples of physical visualizations and related artifacts and is absolutely fascinating (the older artifacts in particular). Take these stick charts from the Marshall Islands for example:
These physical visualizations show ocean swell patterns, and were built by native Micronesians from the Marshall Islands to facilitate canoe navigation. They were memorized before trips. The Western world remained unaware of the existence of these artifacts until 1862.
The photo above is a stick chart from 1974. Straight sticks represent regular currents and waves, curved sticks represent ocean swells, and seashells represent atolls and islands.
Women from the Yakama Native American tribe used strings of hemp as personal diaries. Each major event in their life was represented by a knot, a bead or a shell. This mnemonic device is called an Ititamat, or counting-the-days ball, or simply time ball.
A young woman would use a time ball to record her courtship, marriage, and other experiences using a system of knots and beads that only she could decipher. As she grew older, a woman might have several time balls with which to share her life story or keep those memories private. When she passed on, they were buried with her.
The ball of twine grew in size as time passed and as events occurred. The women would sometimes divide the twine into 25-year lengths to make it more manageable. When the women were very old, they could use the knots and beads of their time balls to recall not only what happened in their lives but when the events occurred. They could easily recount when their children were born, when they moved away, and other major experiences.
Have you ever wondered how mapmakers made bird’s-eye-view maps before the invention of satellites or even hot air balloons? I have and was glad to find Phil Edwards’ video on the subject:
Leonardo da Vinci is justly famous for a lot of different things, but we’ve heard somewhat less about his mapmaking prowess than his painting or mechanical designs. His 1502 map of the Italian town of Imola is the oldest surviving example of an ichnographic (i.e. bird’s-eye-view) map of a place, a type of map that is ubiquitous today in the form of satellite imagery.
Most Renaissance maps are known for their fanciful inclusion of dragons, castles, and undulating mountainsides, and most of them show buildings in elevation, or the “oblique perspective.” But da Vinci’s sought to capture the proportions and relationships between land features more accurately, and he developed new technologies to do so. To make this map of Imola, he may have used the special hodometer and magnetic compass he’d already invented (he’d been fascinated by maps and optics for years). With careful measurements in hand, he drew every “street, plot of land, church, colonnade, gate and square, the whole encompassed by the moat,” writes the Renaissance historian Paul Strathern.
As Edwards notes in the video, Leonardo’s map is not strictly an illustration or drawing of a place but more of an infographic. We take this type of map for granted now, but 500 years ago, that shift was a genuine innovation.
This is a map of ARPANET circa May 1973 via David Newbury, who found it among his father’s papers. The first part of ARPANET was built nearly 50 years ago and became the basis of the modern internet. The network was so small in the early days that those circles and squares on the 1973 map represent individual computers and routers, not universities or cities.
The Library of Congress has a remarkable digitized work in its collection titled “An anciente mappe of Fairyland : newly discovered and set forth,” by Bernard Sleigh, published in London around 1920. Here’s the high-resolution image so you can see some of the detail:
The map aims to be a nearly comprehensive atlas of the world of common English fairy tales, with a few of its own twists and turns. The accompanying guidebook lays out the map’s unique, ontological take on folktales and faerie stories, with the following introductory paragraph (with a quote from Keats’s “Ode to a Nightingale”):
Of the Land of Faerie and of the way thereto
In the Heart of every child, is hidden away a golden key which unlocks the door of a silent, clean-swept room full of changing lights and mystic shadows. There, every child that is born into the world enters at times to gaze eagerly upon the one great window, pictured with ancient legends, and glowing with many colours: amber and scarlet, lapis blues and strange greens. And it is written in many places with curious letters of silver upon black and black upon silver.
About these,
“Charmed magic casements, opening on the foam
Of perilous seas, in faery lands forlorn,”
there lingers a faint, plaintive music, as of far-away organ pipes, of whispering harps, and the sighing of wind amongst the reeds. You would think, at times, it was but the droning of bees in the clover field, or the fall of surf upon some long white beach. It is always there, rising, swelling, dying away in a long, pulsing, voiceless harmony, and through the jewelled panes the light changes continually from that of a pale, cold starshine to the white glory of unclouded moons; and again to the rich warmth of an Eastern sun. Always too, there is the fragrance of enchanted winds, a breathless scent that is like the fading memory of all the flowers that have raised their glad faces to the sun, and closed them softly beneath the Evening Star.
At one time or another of its life, every child that is born of woman sets trembling fingers to open wide the flashing casements — to stand gazing, awed and silent, upon a sea and sky of gold and crimson, full of winged forms grey against its summer radiance.
It goes on like this. I hope you find it charming. (I do.)
One of the many things this is useful for, besides its own right, is in understanding the cultural mentality in which works like The Lord of the Rings, CS Lewis’s writings, Walt Disney’s films, and the like were shaped. There was a real grappling with European folk stories, from the 19th century onwards, but the 20th century added a metaphysical dimension, a desire to make these stories real, to fix them in a place, to give them their own world. I find that desire fascinating, especially coming out of the horrors of World War I, and the destruction of so much of what had been the old Europe.
In general, the most politically intolerant Americans, according to the analysis, tend to be whiter, more highly educated, older, more urban, and more partisan themselves. This finding aligns in some ways with previous research by the University of Pennsylvania professor Diana Mutz, who has found that white, highly educated people are relatively isolated from political diversity. They don’t routinely talk with people who disagree with them; this isolation makes it easier for them to caricature their ideological opponents. (In fact, people who went to graduate school have the least amount of political disagreement in their lives, as Mutz describes in her book Hearing the Other Side.) By contrast, many nonwhite Americans routinely encounter political disagreement. They have more diverse social networks, politically speaking, and therefore tend to have more complicated views of the other side, whatever side that may be.
We see this dynamic in the heat map. In some parts of the country, including swaths of North Carolina and upstate New York, people still seem to give their fellow Americans the benefit of the doubt, even when they disagree. In other places, including much of Massachusetts and Florida, people appear to have far less tolerance for political difference. They may be quicker to assume the worst about their political counterparts, on average.
If you click through to the article, the interactive map will let you see how prejudiced your county is. There are also maps for Republican on Democratic prejudice and Democratic on Republican prejudice.
This map is a little bit bonkers…I can’t wrap my head around some of the results. Why are Florida and South Carolina so polarized while the states surrounding them are not? And look at New York…aside from NYC, there’s relatively little polarization right up against a very polarized New England and Pennsylvania. Utah sticks out among western states but you can probably chalk that up to Mormonism. Is this a methodology problem or is it due to something fundamentally different about the states and/or their governments?
Here’s a closeup view of part of the map, which shows just how much detail is there:
Often Washburn was dropped off on top of a pinnacle or small butte along with surveying equipment, such as a state-of-the-art laser range-finder device still under development, on loan from the company that made it. Using a built-in telescope, Washburn would aim the helium-neon laser at a reflecting prism positioned on another point miles away. The laser beam would be reflected back to the range finder, which measured how long the beam’s round-trip took and translated that into distances that were accurate to within 6/100 of an inch per mile. Washburn used a 40-pound surveying instrument called a theodolite to measure the angles between each of the control points, providing him with the relative position and height of each set of points.
After a few weeks in the canyon, Washburn was convinced of the potential for “a map of really superlative beauty as well as topographic quality.” Knowing exactly where to find the expertise, and the funds, needed to realize that potential, he asked the National Geographic Society to join the project.
The surveying took years and then came the data analysis & production phases…it took over 1000 hours just to paint the relief shading onto the map. If you want to compare Washburn’s map to earlier efforts, check out this post at Codex 99. This 1903 USGS map was the best map into the 1960s:
We’ve looked before at maps of Odysseus’s travels in The Odyssey (as Jason wrote in 2018, “that dude was LOST”). But it turns out — and maybe this shouldn’t be surprising — that it’s not easy to figure out exactly where Odysseus was in the Mediterranean Sea for all that time.
Ithaca is one of a group of four islands, with smaller islands nearby, but it faces west while the others face east. (What does it mean for an island to face a direction?) It has forests and at least one mountain, and it is a good place for raising children. That isn’t much to go on.
Then there’s the whole question of what we gain from mapping The Odyssey in detail anyways. Some of it is plugging a gap in our imagination; we’ve gotten used to fantasy worlds supplying us with maps, and The Odyssey is a fantasy world that coexists with our own. But the level of detail is obsessive.
Attempts to map the Odyssey seem different from other attempts to locate the sites of famous myths and legends. Atlantis was the site of a wondrous civilization, Troy the landscape for an epic battle; finding them in the real world would mean discovering rich sources of evidence about past cultures. El Dorado’s location seems to have been coveted mainly for the lost city’s purported riches, Bimini for its rumored fountain of youth. But what do we gain by knowing where Helios kept his cows? Or which rocky, uninhabitable cave a kidnapping nymph called home?
Nevertheless, there’s a long history of scholars, artists, kings, and more attempting to write themselves into the myth of The Odyssey. The Aeneid, which simultaneously reimagines the founding of Rome as part of the story of the Iliad and Odyssey and elevates Virgil’s Latin poetry to the epic heights of Homer, is the most famous attempt to shore up a claim to legitimacy by appealing to the reality of the Odyssey’s ancient past.
But where exactly was Odysseus? Was he mostly in the Aegean and Italy, as Abraham Ortelius believed in 1597? Or was he scattered into the western Mediterranean, Spain, Corsica, North Africa, as Peter Struck thinks? We’ll probably never know. That dude was LOST.
Grad student Martin Jan Månsson has created this incredibly detailed map of trade route networks in Europe, Asia, and Africa in the 11th and 12th centuries.
Even before modern times the Afro-Eurasian world was already well connected. This map depicts the main trading arteries of the high middle ages, just after the decline of the Vikings and before the rise of the Mongols, the Hansa and well before the Portuguese rounded the Cape of Good Hope.
The map also depicts the general topography, rivers, mountain passes and named routes. All of which contributed to why cities came to be, and still are, up until modern times.
The high middle ages were a time when the stars aligned in terms of commerce for many areas of the world. In central Europe many German and French cities initiated annual trade fairs, some of which are still active today — most notably in Frankfurt. The Europeans have redeveloped a demand for eastern goods as a result of the crusades in Iberia and the Levant. The Italian city states and some north eastern Iberian cities had shipped the crusaders back and forth in the Mediterranean sea, building up huge fleets and setting up networks of trade all around the Mediterranean shores. The Italians frequented ports such as Alexandria, which had separate trading ports for muslim and christian ships.
The saying is that “all roads lead to Rome” but as this map shows, that assertion belongs to an earlier era. In the 12th century, it was more accurate to say that all roads lead to Constantinople or Cairo or Baghdad or Hanzhong…or perhaps even “all roads lead to everywhere”. It’s not quite globalization, but many of the world’s peoples were well on their way to connecting with everyone else.
P.S. I have heard many good things about Peter Frankopan’s The Silk Roads. It’s been sitting on my (virtual) bedside table for several months now…I think I might make it my next read. Has anyone read it?
There’s a little-known monument located at the site of the Hoover Dam that shows the progression of “North Stars” as the Earth moves through its 25,772-year change of rotational axis. Alexander Rose of the Long Now Foundation couldn’t find much public documentation related to this celestial map, so he did some research.
I now had some historical text and photos, but I was still missing a complete diagram of the plaza that would allow me to really understand it. I contacted the historian again, and she obtained permission from her superiors to release the actual building plans. I suspect that they generally don’t like to release technical plans of the dam for security reasons, but it seems they deemed my request a low security risk as the monument is not part of the structure of the dam. The historian sent me a tube full of large blueprints and a CD of the same prints already scanned. With this in hand I was finally able to re-construct the technical intent of the plaza and how it works.
In order to understand how the plaza marks the date of the dam’s construction in the nearly 26,000-year cycle of the earth’s precession, it is worth explaining what exactly axial precession is. In the simplest terms, it is the earth “wobbling” on its tilted axis like a gyroscope — but very, very slowly. This wobbling effectively moves what we see as the center point that stars appear to revolve around each evening.
Presently, this center point lies very close to the conveniently bright star Polaris. The reason we have historically paid so much attention to this celestial center, or North Star, is because it is the star that stays put all through the course of the night. Having this one fixed point in the sky is the foundation of all celestial navigation.
Here are some explanatory notes that Rose wrote over the blueprints of the monument showing how to read the map:
Designer Scott Reinhard takes old geological survey maps and combines them with elevation data to produce these wonderful hybrid topographic maps. From top to bottom, here are Reinhard’s 3D versions of a 1878 USGS Yellowstone map, a 1904 USGS map of Acadia National Park, and a 1899 USGS map of the Grand Tetons.
What really sells it is the shadows cast by the topological part of the map onto the borders; it’s particularly evident in the Teton and Acadia maps. I’d love to see an animated version of the mountains pushing up from the flatness of the map. (via the morning news and several emailers)
This is mesmerizing to watch for a few minutes: a time lapse map of weather activity across the entire US in 2018. I was thinking it would be instructive to see this sped up a bit more, that perhaps different patterns might reveal themselves, and then I remembered that you can control the playback speed on YouTube videos…just click the gear icon. I think I like the 2X version better. (via @DesignObserver)
