Leonardo da Vinci: Italian Renaissance painter, scientist, and polymath

Fields of activity and methods

Leonardo’s interests were unusually broad. He kept dense notebooks in which drawing and text are combined, and he approached problems by close observation, measurement and iterative sketching. His documented occupations and studies include:

• scientist
• mathematician
• engineer
• inventor
• anatomist
• architect
• botanist
• musician
• writer

He studied nature closely and emphasized empirical study over received opinion. His notebooks show careful experiments in optics, fluid flow, the structure of plants, and the mechanics of bones and muscles.

Life, training and patrons

Leonardo was born in the town of Vinci, near Florence in what is now Italy. As a youth he apprenticed in the workshop of Andrea Verrocchio, where he learned painting and sculpture techniques and was exposed to diverse commissions. He spent much of his career working for wealthy patrons and courtly noblemen, who valued the prestige of commissioning art and engineering projects. In his later years he accepted hospitality and a residence from the king of France.

Major works and notable projects

Among Leonardo’s best-known works are the portrait commonly called the Mona Lisa and the mural The Last Supper. He also produced the famous anatomical diagram known as the Vitruvian Man. Beyond finished paintings, his hundreds of sketches and notes record numerous inventions, many of them conceptual rather than built in his lifetime.

• Aeronautics sketches such as a proto-helicopter and early ideas for a parachute.
• Military designs, including a concept resembling an armoured tank and mechanisms for fortification.
• Mechanical devices: a drawing for a mechanical calculator, automata that prefigure a robot, and plans for harnessing natural forces.
• Speculative studies touching on biological change and long-term processes sometimes compared to ideas about evolution, and early thoughts about capturing sunlight that relate to solar power.

Legacy and interpretation

Leonardo's combination of artistic mastery and systematic investigation made him a model for later thinkers. Art historians such as Helen Gardner have observed that his intellect and range were exceptional and that his personality remains partly enigmatic. His work influenced painting techniques, anatomical illustration, engineering drawing and the general view that observation and art can advance scientific understanding.

Though many of his designs were not constructed in his lifetime, his notebooks continue to be studied for their insights into observation, design and interdisciplinary thinking. Museums and scholars preserve his paintings, drawings and pages of manuscripts as central documents of the Renaissance and of the long relationship between art and science.
