Red vs. Blue

What does this map show? Don't skip ahead. See if you can guess what it's about. We'd be pretty amazed if you could.

It shows Europe divided into two blocs. That's not unheard of in history. It's just that these two are bafflingly unfamiliar. It's not the EU versus the rest, nor NATO versus the Warsaw Pact. Not Triple Alliance vs. Triple Entente. Neither Napoleonic France and its satellites versus Britain and its allies. Rome vs. barbarians? Nope.

Let's have a look at who's actually in these two blocs.

• In red: a contiguous slice of Europe, from up in Norway all the way down to Greece, anchored on Germany – the only one of Europe's Big Five (1) in the club. However, the red zone also includes outliers such as Iceland and Ireland.

• In blue: everybody else, in two zones separated by the red one. In the south and west, we find the other four members of the Big Five, and some smaller countries. In the east and north, there's Russia, Turkey and places in between and nearby, including Poland and Ukraine.

These colours denote a difference that is intriguing because you probably never even realised it existed. After this, you won't be able to ever un-see it.

Distance sequencing

• In Red Europe, road signs show city distances from furthest on top to nearest at the bottom. As the example provided shows, if you're driving north on the E4 in southern Sweden, distant Stockholm (557 km away) is listed first, nearby Åstorp, just 13 km down the road, last.

• In Blue Europe, it's the other way around: nearest cities on top, furthest ones at the bottom of the sign. On the E40 in Poland, nearby Kraków (58 km) comes before Jędrzychowice, far away on the German border, 465 km to the west.

Latin vs. Greek

Some involve mysterious lines on the map that divide the world into two wholly unexpected halves. Take for instance the Jireček Line, which divides the Balkan peninsula into areas of Roman and Greek influence, based on archeological finds (see #128).

Football vs. rugby

Or the Barassi Line, which cuts across the east of Australia from the Northern Territories to New South Wales, demarcating the part of the country, west and south of the line, where Australian-rules football is more popular, from the part to the line's east and north, where rugby (league or union) sets more hearts racing.

The Hajnal Line

And then there's the Hajnal Line, roughly from St Petersburg to Trieste, that divides Europe into two distinct zones of 'nuptuality': west of the line, marriage rates and fertility are comparatively low, even before the 20^th century; to the east, both are (or were) comparatively high. Prior to relatively modern times, the late marriage pattern in Western Europe was fairly unique in the world.

The Siktir League

Here's a map that fortuitously flashed up the screen a few days ago, showing a weird coalition of countries, from the western Balkans all the way to the borders of China.

Alexander the Great's empire? Not quite. It's a map of countries where the swear word 'siktir' ('get lost' or 'f*ck off') appears in the native language. Considering that these languages include members of the Romance, Slavic, Turkic families, that's quite a feat (2).
