An Italian painter born in 1452, Da Vinci is what most would call the quintessential Renaissance man. With an alleged IQ estimated between 180 and 190, he is widely regarded as one of the greatest painters of all time, and perhaps, the most diversely knowledgeable person to have ever lived. He was an established polymath who worked in the fields of mathematics, engineering, anatomy, geology, botany, architecture, sculpting, painting, music, and literature.
More than that, he is particularly famous for his masterpieces: Mona Lisa, the Last Supper, and the Vitruvian Man. A true visionary, he was centuries ahead of his time with his detailed concepts of the helicopter, calculator, tank and the double hull, apart from his outlined theories on solar power, hydrodynamics, and plate tectonics.
he does get the mixture of dry plaster wrong
it quickly started cracking and has destroyed the last supper
but a lot of his stuff actually works IE the parachute, battle tank
