1. Leonardo Da Vinci’s Anatomical Studies: The Spark of Fascination
Leonardo da Vinci’s obsession with anatomical studies was a reflection of the prevailing artistic sentiments of his time. Influenced by theorist Leon Battista Alberti’s advocacy for depicting the human figure grounded in its skeletal and muscular structure, Leonardo’s anatomical voyage likely commenced during his apprenticeship in Verrocchio’s workshop. Inspired by his master or Verrocchio’s neighbor, Pollaiuolo, who was recognized for his captivation with the inner workings of the human body, Leonardo’s curiosity was ignited.
It remains uncertain precisely when Leonardo initiated performing dissections, but it might have happened several years after his relocation to Milan, then a hub for medical investigation. Originally intended as part of his training as an artist, Leonardo’s study of anatomy evolved into an independent pursuit by the 1490s. As he meticulously examined the structure of the human body, Leonardo became increasingly intrigued by the figura istrumentale dell’ omo (“man’s instrumental figure”), endeavoring to comprehend its physical functionality as a creation of nature.
2. The Evolution of Leonardo’s Dissection Techniques
Over the subsequent two decades, Leonardo engaged in practical anatomical work on the dissection table in Milan, and later at hospitals in Florence, Rome, and Pavia. In Pavia, he collaborated with the physician-anatomist Marcantonio della Torre, further enriching his understanding of the human anatomy. Leonardo’s commitment to anatomical exploration is evident in his diligent work, as he personally dissected approximately 30 corpses throughout his lifetime.
Leonardo’s early anatomical studies focused on the skeleton and muscles. However, even from the beginning, Leonardo integrated anatomical research with physiological inquiry. Moving beyond the static structure of the body, Leonardo proceeded to examine the role of individual body parts in mechanical activity. This exploration ultimately led him to investigate the internal organs, with a particular focus on the brain, heart, and lungs, which he regarded as the “motors” of the senses and of life.
2.1 The Renaissance Vision: Leonardo’s Integration of Art and Science
Leonardo’s groundbreaking findings from these studies were meticulously documented in the form of anatomical drawings, which stand as some of the most remarkable accomplishments of Renaissance science. These drawings seamlessly merged natural and abstract representation, offering a deep understanding of the body.
Leonardo achieved this synthesis by depicting body parts in transparent layers, providing an “insight” into the organ through the use of sections in perspective. Additionally, he portrayed muscles as “strings,” indicated hidden parts using dotted lines, and developed a unique hatching system. The true value of these dimostrazione lay in their capacity to synthesize a wide array of individual experiences at the dissecting table, rendering the data immediately and accurately visible. Leonardo himself emphasized that these drawings surpassed the descriptive power of words.
The surviving collection of Leonardo’s anatomical studies laid the groundwork for the fundamental principles of modern scientific illustration. It is essential to note that Leonardo’s medical investigations remained confidential during his lifetime. Leonardo did not identify as a professional anatomist, and he did not instruct others or publish his findings.
3. Understanding Human Proportion: The Vitruvian Man
While Leonardo maintained the privacy of his anatomical studies, he did disseminate some of his observations on human proportion. Collaborating with mathematician Luca Pacioli, Leonardo studied the proportional theories of Vitruvius, the 1st-century-BCE Roman architect, as presented in his treatise De architectura (“On Architecture”).
By applying the principles of geometry to the configuration of the human body, Leonardo demonstrated that the ideal proportion of the human figure aligns with the forms of the circle and the square. In his famous illustration of this theory, known as the Vitruvian Man, Leonardo illustrated that when a man stands firmly on the ground with his arms outstretched, he can be contained within the four lines of a square. However, when in a spread-eagle position, he can be inscribed within a circle.
3.1 The Human Body as a Microcosm
Leonardo envisioned the comprehensive picture chart of the human body he had produced through his anatomical drawings and Vitruvian Man as a cosmografia del minor mondo (“cosmography of the microcosm”). He posited that the workings of the human body served as an analogy, in microcosm, for the workings of the universe. Leonardo wrote, “Man has been called by the ancients a lesser world, and indeed the name is well applied; because, as man is composed of earth, water, air, and fire…this body of the earth is similar.”
He drew comparisons between the human skeleton and rocks (“supports of the earth”) and likened the expansion of the lungs during breathing to the ebb and flow of the oceans.
4. Mechanics and Cosmology: Leonardo’s Interdisciplinary Approach
Leonardo’s observations extended beyond anatomy to encompass the study of mechanics, with which he gained familiarity as an architect and engineer. He believed that mechanics also mirrored the workings of nature. Throughout his life, Leonardo was an inventive builder, possessing a thorough understanding of the mechanical principles of his time and making significant contributions to their advancement.
The two Madrid notebooks delve extensively into his theory of mechanics. The first was written in the 1490s, while the second was composed between 1503 and 1505. Their significance lies not so much in their description of specific machines or work tools but in their utilization of demonstration models to elucidate the fundamental mechanical principles and functions employed in building machinery. Similar to his anatomical drawings, Leonardo developed precise principles of graphic representation—stylization, patterns, and diagrams—that provide a clear depiction of the object in question.
4.1 Leonardo’s Contributions to Engineering
Leonardo was also actively engaged as a military engineer, particularly during his time in Milan. However, definitive examples of his work remain elusive. The Madrid notebooks revealed that, in 1504, he assisted the lord of Piombino in repairing the city’s fortifications system and proposed a detailed plan for its overhaul, likely dispatched by the Florentine governing council. His studies for large-scale canal projects in the Arno region and in Lombardy demonstrated his expertise in hydraulic engineering.
Leonardo’s fascination extended to problems of friction and resistance, and with each of the mechanical elements he presented—such as screw threads, gears, hydraulic jacks, swiveling devices, and transmission gears—drawings took precedence over written explanations. Throughout his career, he remained captivated by the mechanical potential of motion. This led him to design a machine with a differential transmission, a mobile fortress reminiscent of a modern tank, and a flying machine. His “helical airscrew” (circa 1487) bears a striking resemblance to a prototype for the modern helicopter, but, like his other vehicle designs, it encountered a significant obstacle: the lack of a suitable power source to provide propulsion and lift.
5. Leonardo’s Artist-Scientist Synthesis
As the 15th century drew to a close, Scholastic doctrines waned, while humanistic scholarship gained prominence. Leonardo, however, belonged to an intellectual circle that cultivated a third, distinctly modern form of cognition. In his perspective, the artist, as a conveyor of true and accurate data derived from visual observation, played a pivotal role.
In an era that often likened the process of divine creation to the activity of an artist, Leonardo reversed the analogy, employing art as his own means to approximate the mysteries of creation. He asserted that, through the science of painting, “the mind of the painter is transformed into a copy of the divine mind, since it operates freely in creating many kinds of animals, plants, fruits, landscapes, countrysides, ruins, and awe-inspiring places.”
With this profound sense of the artist’s calling, Leonardo approached the vast expanse of nature to uncover its secrets. His utopian vision of transmitting knowledge in an encyclopedic manner was still intertwined with medieval Scholastic concepts. However, the outcomes of his research constituted some of the foremost achievements of the forthcoming age’s thinking, owing to their unprecedented reliance on the principle of experience.
5.1 Empiricism and Visual Observation
Despite his fervent endeavors to acquire proficiency in languages, natural science, mathematics, philosophy, and history, as evidenced by the extensive contents of his library, Leonardo remained an empiricist of visual observation. It was through this observation, coupled with his innate genius, that he formulated a distinctive “theory of knowledge” in which art and science converged.
In light of his overarching accomplishments, debates over what he completed or left unfinished become irrelevant. The essence lies in his intellectual prowess, which is self-contained and inherent in each of his creations—a force that continues to ignite scholarly interest today. Indeed, discussions have extended into the personal realm of his life—concerning his sexuality, religious beliefs, and even his potential vegetarianism—which merely corroborates and reflects what has long been apparent: whether the subject is his life, his ideas, or his artistic legacy, Leonardo’s influence shows no signs of diminishing.
6. Leonardo’s Enduring Legacy in Science
Wherever Leonardo investigated the phenomena of nature, he discerned the existence of primal mechanical forces that governed the shape and function of the universe. This is evident in his studies of bird flight, which germinated his early notion of the feasibility of a flying apparatus and prompted extensive research into the element of air. His explorations of water, the vetturale della natura (“conveyor of nature”), encompassed both the physical properties of water and its laws of motion and currents. Additionally, he delved into the laws of growth governing plants and trees, as well as the geologic structure of earth and hill formations. Lastly, he observed air currents, which evoked the image of a candle’s flame or a wisp of cloud and smoke.
In his drawings derived from numerous experiments, Leonardo discovered a stylized form of representation that was uniquely his own, especially in his studies of whirlpools. He adeptly dissected a phenomenon into its component parts—the traces of water or eddies of the whirlpool—while simultaneously preserving the holistic picture, thereby cultivating both an analytical and a synthetic vision.
