177. Here, then, is the practical advice which I would venture to deduce from what I have tried to show you. Use Greek art as a first, not a final, teacher. Learn to draw carefully from Greek work; above all, to place forms correctly, and to use light and shade tenderly. Never allow yourselves black shadows. It is easy to make things look round and projecting; but the things to exercise yourselves in are the placing of the masses, and the modelling of the lights. It is an admirable exercise to take a pale wash of color for all the shadows, never reinforcing it everywhere, but drawing the statue as if it were in far distance, making all the darks one flat pale tint. Then model from those into the lights, rounding as well as you can, on those subtle conditions. In your chalk drawings, separate the lights from the darks at once all over; then reinforce the darks slightly where absolutely necessary, and put your whole strength on the lights and their limits. Then, when you have learned to draw thoroughly, take one master for your painting, as you would have done necessarily in old times by being put into his school (were I to choose for you, it should be among six men only--Titian, Correggio, Paul Veronese, Velasquez, Reynolds, or Holbein). If you are a landscapist, Turner must be your only guide (for no other great landscape painter has yet lived); and having chosen, do your best to understand your own chosen master, and obey him, and no one else, till you have strength to deal with the nature itself round you, and then, be your own master, and see with your own eyes. If you have got masterhood or sight in you, that is the way to make the most of them; and if you have neither, you will at least be sound in your work, prevented from immodest and useless effort, and protected from vulgar and fantastic error. And so I wish you all, good speed, and the favor of Hercules and of the Muses; and to those who shall best deserve them, the crown of Parsley first and then of the Laurel.
