Leonardo da Vinci's profound interest in machinery stemmed from his deep curiosity about the nature of motion. His explorations in various engineering devices were not merely about creating functional tools but were also a reflection of his broader fascination with how things moved and interacted in the physical world. This connection between mechanics and motion played a significant role in his artistic and scientific endeavors, influencing his inventions and paintings.

Walter Isaacson's book on Leonardo highlights how this intrigue with machinery translated into numerous innovative designs and concepts. Da Vinci's sketches and writings reveal an exceptional understanding of the physical forces at play and a desire to capture the essence of movement, whether in the human body or in mechanical creations. His ability to blend art and science is exemplified in his engineered visions, showcasing his genius in both fields.
