Anyone who invokes authors in discussion is not using his intelligence but his memory.
Leonardo da VinciI love this site. It was lovingly hand-shaped it. Your soul transformed this into this art. It was perfect. I have tried to create another equal to it... but to no avail, so I will just have to paint the Sistine Chapel.
Leonardo da VinciYou should look at certain walls stained with damp, or at stones of uneven color. If you have to invent some backgrounds you will be able to see in these the likeness of divine landscapes, adorned with mountains, ruins, rocks, woods, great plains, hills and valleys in great variety; and expressions of faces and clothes and an infinity of things which you will be able to reduce to their complete and proper forms. In such walls the same thing happens as in the sound of bells, in whose stroke you may find every named word which you can imagine.
