A London-based dentist, Rory Mac Sweeney, discovered a hidden equilateral triangle within Leonardo da Vinci’s 鈥榁itruvian Man鈥 drawing.
This triangle, found between the man’s legs, matches Bonwill’s triangle, a modern anatomical concept explaining efficient human jaw mechanics.
The discovery, published in the Journal of Mathematics and the Arts, suggests da Vinci understood ideal human body design centuries before modern science.
The triangle’s presence helps create a 1.64 ratio between the square and circle in the artwork, closely mirroring a natural 鈥渂lueprint number鈥 of 1.633.
This finding indicates 鈥榁itruvian Man鈥 is a scientific work demonstrating a universal rule of design, linking human anatomy to the mathematical elegance found in nature.
