In what I think is the last set of diagrams and illustrations describing the fortifications of Ville de Québec, we have the reason why the overall design and construction were so difficult as well as why there are so many star-like bastions pointing out of the walls.
The difficulty comes from the topography. Québec was, as I mentioned earlier, described by Charles Dickens as the Gibraltar of North America. It features a high, defensible cliff and then a city on the lowlands below it. But building a wall that defends it from the cliffs to the river is not easy. Especially because the angles and slopes of the walls have to account for the fact that enemy cannon near Cap Diamant could otherwise see very well into the city below. And therefore target the city. But how drastic was the descent?

And then to point the second, why so many stars? Well, the problem with straight walls is that if you manage to get beneath the firing range of the cannon along the wall, the defenders really cannot fire at you. And that gives you all the time to plant explosives and blow a massive hole in the fortifications. So the stars actually give the defenders nearly a complete field of fire along the entirety of the city walls.

Today I have a little bit more about the fortifications near Artillery Park. The original fortifications were not massive stone works, because those take time. Instead, a lot of the original defences of the town were wooden palisades and earthworks. The following illustration shows the wooden defences of 1690.

The woodworks were more than just timber inserted into the ground. It involved some earthworks to support the wooden posts, but also to give the defenders a better view of the approaches. And a better firing position.
The palisades were divided into sections by redoubts. These were the strongpoints along the town walls.

But due to the ever-present fear of an amphibious invasion, the palisades were eventually replaced with an earthwork fortification. Trees were planted along the walls and they served as spikes to deter forces from scaling the walls.

Beyond la Citadelle, Québec also enjoys a defensive wall that nearly surrounds Vieux-Québec, or Old Québec. These graphics come from the Barracks Sector, which used to house the Royal Artillery during the British period.

The walls in this section of the city date to 1745, but the redoubt in this area goes back to 1712, you can see that as the orange rectangle.

Yesterday’s piece was from the Musée de la Civilisation à Québec and looked at a bilingual exhibit on Greek and Roman mythology. The museum, of course, had many other exhibits. Today I want to show an interesting bit that explained why the museum, a modern construction dating to the late 1980s, incorporated an 18th century house called Maison Estèbe.

Well, the museum had a series of graphics with text explaining why. But they were only in French. But by some smart use of graphics and some thought as to how show the progression of time, the reader can piece together a good bit of the story.

And of course to make it abundantly clear, the excavation of Québec’s foundations also revealed longboats along the old shoreline, which when placed in front of a quay like below, just make perfect sense.

Well, okay, actually there is. But the cultural reference would have made even less sense if I omitted the negative. Anyway, in honour of the two baseball games I am seeing this week—last night’s and tonight’s Red Sox games—here comes this piece from Pew Research Center.
It’s a simple but fairly clear graphic. We are looking at the ethnic breakdown of baseball since 1947, when Jackie Robinson broke the colour barrier. My only qualm, as ever, with this stacked area chart is that while you can see the clear trend upward in white share, it is a bit more difficult to see the directions the other ethnicities are moving.

Last month, police in Hong Kong defused a 2000 pound (900 kilogram) bomb found undetonated since World War II. The South China Morning Post created a small graphic to diagram just what the bomb was and how it was delivered (by US aircraft) to Hong Kong.
Not “the Ukraine” as it is (admittedly) fun to do in pop-culture references to Seinfeld. This comes from the Washington Post and the article tries to show that the protests in Kiev are not necessarily a vast majority against the government. Certainly the opposition is strong, but there is also a very strong pro-government movement. Why? Because in the broadest of senses, Ukraine is where the West, i.e. the European Union, meets the East, i.e. Russia.

Today’s post comes from a co-worker and looks at the increase of speed in speed skating in the Winter Olympics since 1924. It does a nice job of showing the increase in the speed. Because to a degree, the increase has not been linear. Instead, it really only increased in two spurts and recently has remained fairly constant.
Then to show how slight differences in speed impact an actual race. The times are plotted against the distance in a simulated race. That shows that seemingly incremental increases in speed can have a drastic impact on where one finishes a race.

Today’s post comes via Business Insider. They linked to work by reddit user sp07 who mapped out words used for common objects across Europe and then looked at those words by their origin. But of all words, this is probably the most important.
This time last year, the Northeast began to pick up what was left from Hurricane Sandy. There was a lot of rain, a lot of wind, flooding, and electrical outages. But not all the damage was ashore. In an excellent long-form narrative piece, the Tampa Bay Times covered the story of the Bounty, a functional replica of HMS Bounty from that famous story of a mutiny. This Bounty was used in the 1960s movie and had sailed ever since until it sank off Cape Hatteras, North Carolina.

The piece doesn’t makes use of some charts and graphics to explain positioning and familiarise the reader with terminology. It’s a fascinating though ultimately tragic story. And like so many of these long-form pieces, the credit list is extensive.
