Leonardo da Vinci Drawings
Skip navigation. These groundbreaking illustrations of the fetus reveal his advanced understanding of human development and demonstrate his role in the vanguard of embryology during the Renaissance.
His famous embryological drawings of the fetus have since been collected and held in the Royal Collection at Windsor Castle in England. Leonardo first ventured into human anatomy with the purpose of depicting the human body more accurately in his artwork. Although there is some evidence of his intentions to do so, Leonardo never published his work. The ultimate distribution of his journals and drawings is attributed to Orazio, the son of Francesco Melzi who was the faithful disciple to whom Leonardo entrusted his notebooks in his last testament.
Four years later the expertise he gained with the help of della Torre would prove most useful in his studies of embryology. In one of his most famous drawings, Leonardo depicts a human fetus lying inside a dissected uterus. Leonardo is considered to be the very first in history to correctly depict the human fetus in its proper position within the womb. He was also the first to expertly draw the uterine artery and the vascular system of the cervix and vagina, leonardo da vinci research paper.
Leonardo is credited with drawing the uterus with only one chamber, contradicting theories that the uterus was comprised of multiple chambers which many believed divided fetuses into separate compartments in the case of twins.
Further drawings leonardo da vinci research paper the umbilical vessels illustrate his belief that menstrual blood nourished the fetus through the umbilical cord. Leonardo showed the umbilical cord connecting to the liver and his drawings of hepatic veins show the passing of blood to the heart. In his drawings, the feet of the fetus are crossed and the right foot is shown as blocking the urinary passage.
Leonardo used a method of cross-sectional representation for his depictions of veins, leonardo da vinci research paper, arteries, and nerves in order to show the layouts in greater detail. He was also fond of drawing four leonardo da vinci research paper of the subject so that every angle could be seen by the viewer for a more inclusive study, which he did for leonardo da vinci research paper drawings of the fetus.
His drawings followed rigorous techniques often employed by architects to depict three-dimensional views of his subjects. He viewed the body as an architectural masterpiece created by nature, in which the skeleton was akin to rocks that laid the foundation for the body. These illustrative representations give reason to believe that Leonardo did not have any knowledge of the human discoidal placenta. He wrote that all seeds have umbilical cords that break when the seed is ripe, associating the human fetus with the maturing seed of a plant.
The uterus is drawn splayed open to reveal the fetus much like an opening seed pod reveals its contents. Leonardo also makes drawings of flower-like projections, called cotyledons, within his drawing of the womb which are found in a cow uterus but not in humans. His depictions of the curled up fetus in the womb seem analogous to the seed that grows and becomes ready to unfold and blossom.
His approach of classifying, quantifying, and repeating his experiments was a wholly modernistic approach to his scientific methods. What began as work to capture the human features more precisely in artwork eventually turned into a task of accurately illustrating for the first time the human fetus inside the womb. Leonardo corrected a few misnomers of the time through his observations, while leaving more to be discovered, leonardo da vinci research paper, and his detailed drawings reflect unprecedented curiosity in depicting embryological anatomy.
