Humanism Elements That I Proposed

Throughout my whole life, I contributed to humanism through my paintings and inventions. I also studied the human body and was given permission to dissect a human body in many cities. I created drawings of this and they were published many years after I died. I also made one of the very first drawings of the fetus. I claimed to have invented all sorts of machines for protection of the city. Other things I also invented were the hang glider and the helicopter.
