I know that Leonardo Da Vinci is very famous but what is so important about his achievements?

Da Vinci is widely considered to be one of the greatest painters of all time and perhaps the most diversely talented person ever to have lived.[2] According to art historian Helan Gardener , the scope and depth of his interests were without precedent and "his mind and personality seem to us superhuman, the man himself mysterious and remote".[1] Marco Rosci points out, however, that while there is much speculation about Leonardo, his vision of the world is essentially logical rather than mysterious, and that the empirical methods he employed were unusual for his time.
