“sculpting is a messier endeavor, one not suitable for a gentleman of the court. The sculptor is “pasted and smeared all over with marble powder . . . his dwelling is dirty and filled with dust and chips of stone,” whereas the painter “sits before his work at the greatest of ease, well dressed and applying delicate colors with his light brush.” Isaacson, Walter. Leonardo da Vinci (p. 262). Simon & Schuster. Kindle Edition. ”
