I believed before that (journey to Italy in 1875)... that movement was the whole secret of this art, and I put my models into positions like those of Michael Angelo. But as I went on observing the free attitudes of my models I perceived that they possessed these naturally and that Michael Angelo had not preconceived them, but merely transcribed them according to the Personal inspiration of human beings moved by the need of action. I went to Rome to look for what may be found everywhere : the latent heroic in every natural movement.
