Welcome to the explainer. Today we're doing something absolutely incredible. We are diving deep into the mind of a central character in human history. Someone whose very name is basically a synonym for brilliance. We aren't just going to look at his art today. We're going to systematically dissect his mind. We're talking, of course, about the ultimate polymath of the High Renaissance, Leonardo da Vinci. I am so thrilled to guide you through this because honestly, this man's life is the ultimate proof that human potential is vastly larger than we usually dare to imagine. Let's get right into it. To
really wrap our heads around the monumental scale of his modern legacy, let's start with a number. Back in 2017, a painting attributed to Leonardo, the Salvatore Mundi, went up for auction, and it sold for a staggering $450.3 million. Let that sink in for a second. $450.3 million. It set a completely new shatter the glass ceiling record for the most expensive painting ever sold at public auction. Even five centuries after his death, just one single piece of his surviving work commands the wealth of entire nations. But here's the thing, his canvas paintings, they're only a tiny fraction of the story. Now, what's really interesting about this slide is the sheer overwhelming volume of what he left behind. 13,000.
Leonardo left us over 13,000 pages of notes and drawings. He literally carried these notebooks with him everywhere, just constantly filling them with his daily observations. They're this wild fusion of art and natural philosophy written mostly in his famous idiosyncratic mirror image cursive. And he tracked everything from everyday grocery lists to the intricate anatomy of the human heart, right down to designs for walking on water. These pages are the ultimate proof that his genius went far, far beyond the canvas. So here is our cognitive road map for this explainer. We'll kick off with one, the ultimate renaissance man. Then two, the making of a master. Three, the divine painter. Four, the obsessive
scientist. And finally, five, an unfinished legacy. Okay, let's dive into this. Section one, the ultimate renaissance man, defining the universal genius. I mean, what do we actually mean when we throw around the term Renaissance man? Well, in Leonardo's case, it meant mastering a dizzying array of disciplines. We're talking about a guy who was actively working as a painter, a draftsman, an engineer, a scientist, a theorist, a sculptor, and an architect. It's like he lived 10 lifetimes in one. And here is the absolute kicker. He mastered this vast scope of interests without any formal academic training. No formal education in Latin or higher mathematics when he was young. Instead, his entire approach was observational. He had this
insatiable, unquenchable curiosity to understand phenomena just by describing and depicting them in the utmost detail. Now, it's easy to look at that and buy into the myth because he was so brilliant. Even people who lived at the same time as him, like the historian Giorgio Vasari, spoke of him as this supernatural divine entity sent straight from heaven. But the reality, the reality is so much more human and frankly a lot more impressive. Leonardo was actually born out of wedlock in 1452 to a notary and a lowerass woman in the small Tuscan town of Vinci. And because of his illegitimacy, he was completely excluded from all the prestigious professions. He only got a basic
informal education in writing, reading, and math, which means his staggering achievements were entirely self-driven. Moving right along to section two, the making of a master, curiosity, and movement. How exactly did an informally educated kid become this unparalleled master? Well, fascinatingly, if you look at Leonardo's earliest recorded memory from his infant years, or you know, maybe it was a childhood fantasy, it was about a kite, not the toy, but a type of bird coming right down to his cradle. This hyper granular childhood memory is absolutely crucial because it acted as the spark for a profound lifelong obsession with nature and specifically the flight of birds. This early intense
fascination in his infancy would eventually lead him to design flying machines centuries before the first airplanes even existed. No way, right? If we track his life, you'll see Leonardo lived a highly nomadic existence. He started with a pivotal apprenticeship in Barochio's bustling workshop in Florence in the 1460s, then decades serving the Duke of Milan, bouncing back to Florence, down to Rome under the Pope, and finally ending up in France. He lived in a highly volatile, war torn Italy. But, and this is key, this constant movement across different courts actually forced his adaptable genius to evolve. He was constantly reinventing himself. He'd pitch himself as a military architect to Caesar Bourja, then a pageant designer in
Milan, and an engineer in Venice. And man, even as a young guy, his skills were just undeniable. There is this wonderful anecdote from his early years, a local peasant asked Leonardo's father to have a round wooden shield painted. So, the young Leonardo, totally inspired by the myth of Medusa, painted a fire spitting monster on it. And it was so breathtakingly terrifying, so realistic that his father actually secretly bought the peasant a different shield and then turned around and sold Leonardo's masterpiece to a Florentine art dealer for a 100 duckets. It perfectly showcases his early terrifying mastery of realism. Which brings us nicely to section three, the divine painter, where
art meets reality. Let's look at exactly how his intensely scientific brain completely elevated his paint brushes. By the 1490s, people were already calling him a divine painter. And his work is so unique because he wasn't just painting what a human looked like on the outside. He utilized his deep, deep knowledge of anatomy, botany, and geology. He understood exactly how muscles moved under the skin. He knew how humans registered emotion in their micro expressions and exactly how light interacted with complex geological formations in the background. It wasn't just art. It was applied science. And this brilliantly illustrates his technical genius. The technique of
sphumato. Literally translated, it means Leonardo's smoke. He figured out how to lay down oil paints so smoothly and blend the tones so incredibly subtly in the shadowed corners of mouths and eyes that you literally cannot even see the brush strokes. It is the secret sauce behind the elusive mysterious smile of the Mona Lisa. Sumato acts as the absolute perfect bridge between his artistic mastery and his rigorous scientific study of optics. He painted the world exactly as the human eye actually perceives it without any hard harsh lines. Let's pivot hard now into section four, the obsessive scientist, fusing art and natural philosophy. Because for Leonardo, there was absolutely no dividing line between the
two. His approach to anatomy wasn't just a side hobby. It was intensely hands-on and core to his worldview. He got permission to dissect human corpses at hospitals in Florence, Milan, and Rome. He created over 240 detailed topographical anatomical drawings. But he went so much further than just drawing bones, folks. He practically prefigured modern biomechanics. He actually created models of the brain's cerebral ventricles by injecting them with melted wax. And he built a glass aorta, pumping water and grass seeds through it just so he could physically observe the flow patterns of blood through the heart valves. I mean, that is mind-blowing empirical science for the 1500s. And his sheer volume of
inventions, it's almost overwhelming in a good way. We're talking rapid fire brilliance here. He conceptualized an ornithopter, a helical rotor that's basically a helicopter and a parachute. For the military, he's sketching out armored fighting vehicles and a steam cannon. And while sure, his massive war machines were mostly conceptual, some of his smaller manufacturing designs, like an automated bob and winder, actually entered the real world of manufacturing completely unheralded. He just had this unparalleled unique ability to combine existing mechanics into revolutionary new concepts. So the crucial point is that his science was relentlessly driven by observation over pure theory. A great
example of this is perpetual motion. Back then, tons of theorists believed it was possible. Leonardo studied it. He observed it. And he correctly concluded, "Nope, it's impossible." Why? Because in 1493, through pure observation, he figured out the laws of sliding friction. Laws that wouldn't be formally rediscovered by modern science until two whole centuries later. And that brings us to our final chapter, section five, an unfinished legacy, the human behind the genius. Because, as you might imagine, having a mind that is entirely boundaryless comes with a very heavy burden. He wrote this deeply personal, incredibly melancholy quote in his diary during the 1480s. He wrote, "I thought I
was learning to live. I was only learning to die." Despite his limitless curiosity or you know maybe because of it he really suffered from internal struggles. He was a man whose mind simply couldn't stop thinking. He was constantly distracted by a new scientific observation or some new mechanical idea which made it incredibly difficult for him to actually finish the physical art commissions he started. The rule of contrast really defined his later life. On one hand he's celebrated by kings and popes given a vast manner in France by King Francis I. But on the other hand, he was plagued by unfulfilled projects. He completely abandoned the adoration of the magi. That massive bronze equestrian monument
he spent years designing Nevercast. The metal was given away for cannons. And as he aged, he suffered what we believe to be a stroke that left his right hand paralyzed, which totally explains why he left even his most famous masterpiece, the Mona Lisa, technically unfinished in his own possession when he died in 1519. Yet despite all the delays, his 16th century biographer, Giorgio Vasari, captured his essence perfectly. Even the people who lived alongside his flaws and his unfinished commissions viewed him as a genuinely superhuman gift to the world. He was a man whose observations and understanding of the universe were so far ahead of his own century that his peers could only look at him and
attribute his mind to the divine. Which leaves us with this final provocative thought to take away from our explainer today. We live in an era of intense hypers specialization, right? Where art and science are so often kept in entirely separate boxes. But Leonardo da Vinci proved that the deepest truths of the universe are found exactly when those disciplines merge. If a mind of his caliber with his unquenchable curiosity and raw observational power were unleashed with today's technology, what kind of future would he draw for us? Thank you so much for exploring the mind of a true genius with me. Keep observing, keep questioning, and keep learning.
