1627. In addition to the cities and palaces, I have also on occasions been allowed to see the decorative work there, such as that of stairways and of doors. These decorations are full of movement, as though they were living, and constantly change to reveal new beauty and symmetry. I have been told that such variations can continue in this fashion, even for ever, with a harmony for ever new, and with the very succession of variations forming a harmony as well. I was also told that these were merely some of the least significant things.
