Leonardo da Vinci was a genius. Everyone knows that. But honestly? He was also kind of a nightmare to work with. He was a chronic procrastinator who started a hundred things and finished maybe ten. One of his biggest "fails"—at least during his lifetime—was the Leonardo da Vinci horse, a project so massive and ambitious that it basically became the 15th-century version of vaporware.
It was supposed to be the biggest bronze statue in the world. A monument to power. Instead, it ended up as a pile of mud and a heap of wasted potential. But the story doesn't actually end with Leonardo's death in 1519. It’s way weirder than that.
The Duke, the Ego, and the 70 Tons of Bronze
In 1482, Ludovico Sforza, the Duke of Milan, wanted a way to honor his father, Francesco. He didn't want a standard statue. He wanted something that would make every other ruler in Italy look poor. He commissioned Leonardo to create a colossal bronze horse. Leonardo, being Leonardo, didn't just want to make a horse; he wanted to reinvent how horses were sculpted.
He spent years studying anatomy. He filled his notebooks—the ones we now call the Codex Madrid II—with sketches of muscles, tendons, and skeletal structures. He wasn't just drawing; he was dissecting. He spent nearly a decade just thinking about it. Imagine being the Duke. You’ve paid this guy a fortune, and all you have to show for it are some sketches of horse thighs and a few clay models.
By 1493, a full-scale clay model finally went on display. It was massive. We're talking 24 feet tall. People were obsessed. It was the talk of Milan. But there was a glaring problem: how the hell do you cast something that big in bronze?
The Technical Nightmare
Leonardo’s plan was insane. Most sculptors at the time cast statues in pieces. Leonardo? No. He wanted to cast the entire thing in a single pour. This had never been done. To do it, he would have needed roughly 70 tons of bronze. He designed a complex system of pits and furnaces to liquefy the metal and pour it simultaneously to avoid "cold shuts" or seams in the metal.

Then, history happened.
War broke out. The French were invading. Ludovico Sforza realized that 70 tons of bronze would be much more useful as cannons than as a giant horse statue. He took the metal. Leonardo was devastated. When the French finally took Milan in 1499, their archers used Leonardo’s giant clay model for target practice. It crumbled. The "Gran Cavallo" was gone. Leonardo died years later in France, reportedly still mourning the fact that he never finished it.
Why the Leonardo da Vinci Horse Still Haunts Art History
For centuries, the horse was just a legend. A "what if" in the margins of history books. Art historians like Martin Kemp have spent lifetimes trying to piece together exactly how Leonardo planned to pull off the engineering. It wasn't just art; it was a massive mechanical challenge.
The complexity of the mold alone was a feat of engineering. Leonardo had to account for the cooling rates of the bronze. If one part cooled faster than another, the whole thing would crack. He was basically trying to solve thermodynamics before anyone knew what that was.

Some people think he never would have finished it anyway. He was a perfectionist. He’d get distracted by the way light hit a leaf or how water swirled in a stream. But the horse was different. It was his chance to prove he was more than just a painter of pretty portraits. It was meant to be his legacy.
The Modern Resurrection
Fast forward to the late 1970s. An American named Charles Dent, a retired airline pilot and art lover, read an article about the lost horse. He decided he was going to finish it. Talk about a side project. He founded Leonardo da Vinci's Horse, Inc. (now known as Da Vinci Science Center).
It took 17 years.
Dent died before it was done, but the project continued. They hired sculptor Nina Akamu to finally bring the vision to life. But they hit the same wall Leonardo did: how do you make a 24-foot bronze horse look like a Leonardo? Akamu didn't just copy his sketches—she had to interpret his "spirit." She studied his drawings of the Sforza monument and the smaller sketches for the Trivulzio monument.
On September 10, 1999—exactly 500 years after the original clay model was destroyed—the new bronze Leonardo da Vinci horse was unveiled in Milan at the Hippodrome of San Siro.
Where You Can See It Today
You don't have to go to Milan to see the "spirit" of this project. There are actually several versions across the globe:
- Milan, Italy: The full-sized 24-foot version at the Hippodrome.
- Grand Rapids, Michigan: A 24-foot version at Meijer Gardens. It’s stunning in person.
- Allentown, Pennsylvania: A 12-foot version.
- Sheridan, Wyoming: A smaller scale version exists there too.
- Vinci, Italy: Leonardo’s birthplace has a version, which feels right.
The Lesson of the Gran Cavallo
What most people get wrong about Leonardo is thinking he was a failure because he didn't finish things. But the horse proves that the process is what matters. His anatomical studies for the horse paved the way for a deeper understanding of biology. His engineering notes influenced casting techniques for centuries.
Even though he never saw the bronze version, his obsessive documentation allowed people 500 years later to finish his work. That’s a different kind of genius.
If you're ever in Michigan or Milan, go stand under one of these statues. Look at the muscles. Notice the way the bronze seems to ripple. It’s not just a statue of a horse; it’s a monument to the idea that some ideas are too big for one lifetime.
Actionable Insights for Art Lovers and Historians
If you want to dive deeper into the reality of this project without getting lost in the "Da Vinci Code" style myths, here is what you actually need to do:
- Read the Codex Madrid II: This is where the real technical secrets live. You can find digitized versions through the National Library of Spain. It’s way more interesting than a coffee table book because you see his actual struggle with the math.
- Visit Meijer Gardens if you're in the US: Seeing the scale in person is the only way to understand why the Duke of Milan was so stressed about the bronze. The sheer weight of the thing is intimidating.
- Look at the "Rearing Horse" sketches: Leonardo had two versions of the horse. The Sforza one was walking (passant), but he also obsessed over a rearing horse for another patron. Compare them. You’ll see how his understanding of balance evolved.
- Study Nina Akamu’s process: If you’re an artist, look into how she translated 2D sketches into a 3D colossus. It’s a masterclass in interpretive sculpture.
The Leonardo da Vinci horse serves as a reminder that "unfinished" doesn't mean "unsuccessful." It just means the story takes a few centuries longer to tell.
