Famous quotes containing the words elevation and/or model:
“All our lives we fought against exalting the individual, against the elevation of the single person, and long ago we were over and done with the business of a hero, and here it comes up again: the glorification of one personality. This is not good at all. I am just like everybody else.”
—Vladimir Ilyich Lenin (1870–1924)
“If the man who paints only the tree, or flower, or other surface he sees before him were an artist, the king of artists would be the photographer. It is for the artist to do something beyond this: in portrait painting to put on canvas something more than the face the model wears for that one day; to paint the man, in short, as well as his features.”
—James Mcneill Whistler (1834–1903)
