What did Da Vinci mean in his notes that man was the model of the world?

In his notes, Leonardo da vinci suggested that the human body embodies the principles of proportion, symmetry, and function that are also found in the natural world. By studying human anatomy, he believed one could gain insights into universal laws governing nature. This perspective reflects the Renaissance idea of the interconnectedness of humanity and the cosmos, where man serves as a microcosm of the larger universe. Essentially, da Vinci saw the human form as a key to understanding broader scientific and artistic concepts.
