Michelangelo was a master of anatomy who secretly performed dissections to understand the human body. In his masterpiece 'The Creation of Adam' (c. 1511), some neuroanatomists believe he hid a symbol of human intelligence. The red shroud surrounding God and the angels is anatomically identical to a cross-section of the human brain. Specific features like the cerebellum, optic chiasm, and pituitary gland are seemingly represented by the figures and folds. This suggests that Michelangelo believed the 'divine spark' passed from God to man was not just life, but the gift of intellect. This hidden tribute to science within a religious monument perfectly encapsulates the Renaissance ideal of humanism.
