Studies of the Foetus in the Womb

The Studies of the Foetus in the Womb represent Leonardo da Vinci's pioneering anatomical investigations. Created around 1511, these pen and ink drawings show a human fetus at various stages, with the uterus drawn open to reveal its contents. Leonardo's observations combined dissection findings with theoretical speculation.

Leonardo performed numerous dissections throughout his life, documenting human anatomy with unprecedented accuracy. However, these particular drawings show some errors, suggesting he relied partly on animal dissection and earlier texts. The notation explains his belief that the fetus draws nourishment through the umbilical cord and does not breathe until birth.

The drawings are in the Royal Collection at Windsor Castle, part of a major holding of Leonardo's anatomical studies.
