Leonardo da Vinci’s drawings exemplify his unparalleled curiosity and mastery of observation, spanning anatomy, engineering, botany and human expression. Using fine ink lines, delicate shading and dynamic cross-hatching, he meticulously studied the human body, producing anatomical sketches that remain influential today. His scientific mind is evident in technical drawings of machines, architectural designs and natural phenomena, blending art with invention. Portrait studies, such as Study for the Head of Leda, reveal his fascination with movement and emotion. Whether exploring ideal proportions or mechanical innovations, Leonardo’s drawings offer a profound insight into the mind of a Renaissance polymath.
