“take a style of silver… start to copy the easiest possible subjects, to get your hand in; run the style
over the little panel so lightly that you can hardly make out what you first start out to do; strengthening
your strokes little by little, going back many times to produce shadows. And the darker you want to
make the shadows in the accents, the more times you go back to them; and so conversely, go over the
reliefs only a few times.”
