Leonardo da Vinci
Leonardo, although widely known as an artist was a Polymath, a man whose expertise spanned a significant number of subject areas. Da Vinci was a painter, sculptor, architect, musician, mathematician, engineer, inventor, anatomist, geologist, cartographer, botanist, and writer. His genius, perhaps more than that of any other figure, epitomized the Renaissance humanist ideal. Leonardo has often been described as the archetype of the Renaissance Man. He is thought to be one of the most widely talented people to ever have lived. He was also a vegetarian.
Leonardo’s vegetarianism didn’t result from health concerns or a distaste of meat. His notebooks and other sources reveal that he had a respect for animals, and recognised the pain they experienced at the hands of people. He objected to violence of all kinds.
"Men who consume the flesh of beasts consume also the fear of the slaughtered victims, the fill of which will be the virus of discontentment" Leonardo da Vinci
