Leonardo da Vinci

Throughout his career, Leonardo da Vinci developed four primary themes that he intended to organize into formal treatises. These works, which he never completed for publication, include:
- A treatise on painting
- A treatise on architecture
- A book on the elements of mechanics
- A broadly outlined work on human anatomy
Leonardo’s approach to these subjects was grounded in his commitment to saper vedere ("knowing how to see"), prioritizing empirical experience and detailed visual demonstrations over speculative book knowledge. While he left behind a vast legacy of over 10,000 pages of notes and illustrations—now preserved in various codices such as the Codex Atlanticus—these writings remained in a preliminary state at the time of his death.12
