Giorgio Vasari quotes
In our time it has been seen, as I hope to show quite shortly, that simple children, roughly brought up in the wilderness, have begun to draw by themselves, impelled by their own natural genius, instructed solely by the example of these beautiful paintings and sculptures of Nature. Much more then it is probable that the first men, being less removed from their divine origin, were more perfect, possessing a brighter intelligence, and that with Nature as a guide, a pure intellect for master, and the lovely world as a model, they originated these noble arts, and by gradually improving them brought them at length, from small beginnings, to perfection. I do not deny that there must have been an originator, since I know quite well that there must have been a beginning at some time, due to some individual.
Giorgio Vasari
