Leonardo Da Vinci's Life

The term "Renaissance Man" refers to an individual whose expertise spans a significant number of different subject areas. Leonardo embodied this ideal more than any other figure in history. While many know him as a painter, his notebooks reveal a mind that was equally obsessed with anatomy, botany, geology, and fluid dynamics. He did not see science and art as separate disciplines; rather, he used his scientific understanding of light and shadow to perfect his Da Vinci Painting Technique. His ability to observe nature with clinical precision allowed him to create art that felt vibrantly alive, a journey you can explore in detail through our Biography 1452-1500.

The Mona Lisa’s smile is perhaps the most discussed enigma in art history. Leonardo used a technique called sfumato, which involves the blurring of edges and colors to create a smoky effect. Because the corners of her mouth and eyes are softened, the expression appears to change depending on where the viewer focuses. Scientific studies suggest that Leonardo utilized his knowledge of human vision to create an "optical trap" where the smile is more apparent in our peripheral vision than when looking directly at it.

Unlike many of his contemporaries, Leonardo did not use the traditional "buon fresco" method (painting on wet plaster) for The Last Supper. Because he wanted to work slowly and achieve the same level of detail found in oil paintings, he experimented with an experimental tempera and oil mix on a dry wall. Unfortunately, this technique proved unstable, and the painting began to deteriorate within years of completion. Despite centuries of damage and restoration, it remains a masterpiece of perspective and emotional storytelling.

Very few of Leonardo’s more ambitious mechanical designs were ever constructed while he was alive. Most remained as detailed sketches in his private journals. His concepts for a Tank, a flying machine, and Scuba Gear were hundreds of years ahead of the materials and power sources available in the 15th century. However, some of his smaller civil engineering projects, such as specialized pulleys and industrial looms, were likely utilized in the workshops of Florence and Milan. You can see the blueprints for these futuristic concepts in our section on Inventions.

Most of Leonardo’s personal notebooks were written in a script that runs from right to left and requires a mirror to read. While some theorists suggest this was a way to keep his scientific discoveries secret from the Church, the more practical explanation is that Leonardo was left-handed. Writing from left to right with wet ink would have caused his hand to smudge the page; by writing in reverse, he kept his notes clean. This unique habit is one of the many fascinating details we cover in the Leonardo Timeline.

In 1502, Leonardo submitted a proposal to Sultan Bayezid II for a massive bridge to span the Golden Horn in Istanbul. The design was revolutionary: a single span of 240 meters that utilized a "pressed-bow" arch. At the time, it was deemed impossible to build. However, modern engineering simulations and a smaller-scale version built in Norway in 2001 proved that Leonardo’s physics were entirely sound. The Golden Horn Bridge stands as a testament to his prowess as a civil engineer.

While the novel by Dan Brown is a thrilling work of fiction, it often blends historical fact with creative myth. The idea that Mary Magdalene is hidden in plain sight in Leonardo’s paintings is a major plot point, but art historians generally disagree with these interpretations. For instance, the figure to the right of Jesus in the mural is widely accepted by scholars to be the Apostle John.

Leonardo was a pioneer in the field of anatomical study, conducting over 30 dissections of human cadavers during his life. He was the first to accurately depict the human spine’s "S" curve and the first to draw a fetus in the womb. He intended to publish these drawings as a comprehensive treatise on anatomy, but like many of his projects, it remained unfinished at the time of his death. His work in this field was so advanced that it predated modern medical illustrations by centuries.

The Vitruvian Man is a world-famous drawing that illustrates the blend of art and science. Based on the writings of the Roman architect Vitruvius, the drawing explores the "proportions of man." It demonstrates Leonardo’s belief that the human body is the principal source of proportion among the Classical orders of architecture. By fitting the human form into both a square and a circle, Leonardo showcased the geometric harmony of the human body.

There is no historical record of Leonardo ever being married or having children. He was a private individual, and much of what we know about his personal life comes from legal documents and the accounts of his contemporaries. He was known to have very close relationships with his pupils, most notably Gian Giacomo Caprotti (known as Salai) and Francesco Melzi, the latter of whom became the heir to Leonardo’s artistic and scientific estate.

Leonardo passed away on May 2, 1519, at the Château du Clos Lucé in Amboise, France. He was originally buried in the church of Saint-Florentin, but the church was destroyed during the French Revolution. Today, his presumed remains are located in the Chapel of Saint-Hubert at the Château d'Amboise. While the exact identity of the bones remains a subject of scientific debate, the site serves as a major monument to his lasting legacy.

Despite his immense fame, Leonardo was a notoriously slow worker and often abandoned projects to pursue new scientific interests. As a result, there are fewer than 20 paintings in existence that are universally attributed to his hand. Some of his most famous works, such as "The Battle of Anghiari," were lost to history or remained unfinished. This rarity is part of why his surviving works are considered among the most valuable and protected treasures in the world.
