WTF Fun Fact 12713 – da Vinci’s “Helicopter”

It’s hard to put into words the genius of Leonardo da Vinci. You have to look beyond his paintings and into his notebooks to see just how masterfully his brain worked. It’s like he understood the secrets of nature in a way no one else could (either then or now).

For example, in the 1480s, he was already imagining ways to create flying machines. And some might call his “aerial screw” the forerunner of the helicopter. That’s an innovation that it took us 400 more years to actually create!

(It’s only fair to mention that de Vinci’s drawing is not the first-ever of a helicopter-type vehicle. In 400 BCE, Chinese Taoist scholar Ge Hong described a “vertical flying machine” made of bamboo in the Baopuzi, though he was referring to a spinning toy. And since Chinese manuscripts made their way to Europe during the Renaissance, da Vinci was possibly influenced by this. It certainly influenced future helicopter inventors.)

Today, we even call the Renaissance artist’s invention “da Vinci’s helicopter” these days, and he wrote an entire treatise on flight. Just look at a page to see what he was capable of:

In the modern world, companies still bicker over who invented the first real helicopter, so it’s just more fun to give credit to da Vinci.

Of course, the aerial screw isn’t the same helicopter we have today. It’s not like he built a gas engine or anything, but he did conceive of a blade that would lift a vehicle vertically off the ground. His blades were not flat but shaped like a screw or helix.

As physicist Tom Hartsfield described in Big Think:

“What da Vinci lacked was the modern materials necessary to construct a lightweight and durable blade. He described the helical screw as being made of linen, with the pores stopped up by starch.

He also lacked the continuous motive power for such a machine. Men turning cranks could never dream of flying: they are far too heavy and too weak to produce enough power to lift themselves…Cognizant of this limitation, da Vinci envisioned a spring, wound by the crank turners, building up and storing energy. That built-up energy could be released in a quick unwinding burst, spinning the screw rotor. But as far as we know, such a device was never built.”  — WTF fun facts

WTF Fun Fact 12703 – The Ancient Art of Topiary

The art of topiary has a long history and going in and out of style. And we’re not exactly sure who made the first shaped and trained tree or shrub or why.

While the word “topiary” is a 16th-century English term, it comes from the Lain topiarius, meaning ornamental gardener. You can find that word in letters from 1st/2nd century CE author Pliny the Younger’s letters. He described the Tuscan villa of Gaius Matius Calvinus as having many animals and other figures made out of cypress. He introduced the art to his friend Julius Caesar.

When the Roman Empire collapsed, no one really had time for topiary (or for ornamental gardens at all) for a couple of hundred years, although the art was largely preserved among monks who manicured their gardens. (Even a manicured hedge is technically a topiary.)

The artistic boom of the Renaissance brought topiary back into favor among those who could afford ornamental gardens and Italian villas were home to everything from topiary animals to giant bushy obelisks and pyramids.

Of course, many of us associate topiary with the French because of the gardens of Versailles, which is still a premier place to view them to this day. But each country had its own way of doing things – some favored large cones, others liked things at smaller scales.

English gardens are also famous for topiaries, but things got a bit out of hand as people became obsessed with more elaborate shapes and sizes.

By the 18th century, topiary was primed for a take-down as being both too trendy and too ridiculous in some of its forms. So when satirist Alexander Pope wrote a widely-read essay called “Verdant Sculpture” in the newspaper in September 1713, it seemed so spot-on that people were soon embarrassed by their elaborate mazes and giant tree animals. By the 1730s, many mansions had their topiaries removed as people decided they were unstylish in light of the mocking.

Of course, people who didn’t care about the trendiest way to garden still had them, but aristocrats didn’t push the art forward for another century and a half.

By the 1870s, the style became popular in England again and remains popular today.

The U.S. caught up to the gardening trend in the 1950s and 60s when Walt Disney decided to introduce topiaries to Disney World in the shape of his cartoon characters. Now topiary was portable as well and could be brought indoors, which coincided with the rise in popularity of the U.S. houseplant.

(And let’s not forget that many of us aged 40 and up remember Edward Scissorhands as the ultimate topiarist!)

Now you can find topiary around the world in all shapes and sizes, and it shows no sign of going out of style any time soon. – WTF fun facts

WTF Fun Fact 12553 – The World’s Most Stolen Painting

It may be one of the most important paintings in Western history, ushering in the era known as the Renaissance, but Jan van Eyck’s masterpiece Adoration of the Mystic Lamb also has a more dubious honor. It’s the world’s most stolen painting.

Perhaps the most impressive part is that the altarpiece weighs over 2 tons – that’s 4000 pounds! That’s more than a rhinoceros (albeit less aggressive). It also measures 14.5 by 11.5 feet.

Also known as the Ghent Altarpiece, Adoration of the Mystic Lamb has 12 panels depicting everything from the Annunciation, Adam and Eve, the Virgin Mary, John the Baptist, and Jesus himself. But the central theme is an incredibly detailed rendering of pilgrims gathered to honor the Lamb of God.

In 2010, Noah Charney, who authored the book Stealing the Mystic Lamb: the True Story of the World’s Most Coveted Masterpiece, explained the painting’s importance to NPR:

“It’s the first great oil painting — it influenced oil painting for centuries to come. It’s the first great panel painting of the Renaissance, a forerunner to artistic realism. The monumentality of it and the complexity of it fascinated people from the moment it was painted.”

The altarpiece was initially designed to go in the cathedral of St. Bavo in Ghent. And that’s where it stayed for a century.

But in 1566, Calvinist militants set out to destroy the piece. When Catholic guards discovered the plot, they disassembled it and hid it in the cathedral tower. It survived the planned attack, but in 1794 four panels were stolen during the Napoleonic Wars and put on display in the Louvre.

After Napoleon’s defeat in 1815 at the Battle of Waterloo, France sent the painting back to Ghent. But in 1816, a vicar at the cathedral reportedly stole the wing panels, which eventually ended up in the Berlin museum. But in 1919, one condition in the Treaty of Versailles was returning those panels to Ghent.

In 1934, thieves broke into the cathedral and stole the lower-left panel, which has still not been recovered. What’s on display in Ghent currently is a copy of that panel.

Unsurprisingly, the Nazis (known to pilfer priceless art) stole the painting during WWII as it was being transported to the Vatican. They were convinced it held a clue to a mystical treasure map that would help them find the relics of Christ’s passion. Yet it ended up stored away in an Austrian salt mine. The mine was rigged with explosives, but the Allies managed to take the mine, dismantle the bombs, and save all the priceless works of art hidden inside.

More intrigue surrounds the painting, and there were many more attempts to steal it. But today, it’s back in Ghent (though one panel – Righteous Judges – is still a replica since it’s never been located) and on display. –  WTF fun fact
