The Unfinished Genius

Leonardo completed fewer than twenty paintings in his entire life — a tiny output for an artist of his stature. His perfectionism and restless curiosity meant he often abandoned a project the moment a new question pulled his attention elsewhere, leaving a trail of brilliant but incomplete works that still tantalize art historians.

The notebooks reveal the scope of what remained inside his mind. Thousands of pages of drawings and observations on subjects from embryology to architecture suggest that Leonardo's painted masterpieces represent only a fraction of his total vision.
