The most intelligen man: Leonardo Da Vinci.

We know that Leonardo was a famous painter, also a scientist, engineer, inventor, anatomist, sculptor, architect, botanist, philosopher, writer...
But what would have happened if Leonardo Da Vinci had not existed?
Research on human anatomy could have been discovered years later, delaying the evolution in a vital area such as medicine. Inventions such as airplanes, parachutes, pulleys, gears might not have been discovered.

But What I was surprised is that at the time Leonardo had not materials and with few instruments as he made rough drawings of the human body and their inventions.

No doubt Leonardo Da Vinci was the most impressive and intelligent man in the world.
