Among those named for study under question, you cannot look too much at, nor grow too enthusiastically fond of, Angelico, Correggio, Reynolds, Turner, and the Pre-Raphaelites; but, if you find yourself getting especially fond of any of the others, leave off looking at them, for you must be going wrong some way or other. If, for instance, you begin to like Rembrandt or Leonardo especially, you are losing your feeling for color; if you like Van Eyck or Perugino especially, you must be getting too fond of rigid detail; and if you like Vandyck or Gainsborough especially, you must be too much attracted by gentlemanly flimsiness.
257. Secondly, of published, or otherwise multiplied, art, such as you may be able to get yourself, or to see at private houses or in shops, the works of the following masters are the most desirable, after the Turners, Rembrandts, and Dürers, which I have asked you to get first:
1. Samuel Prout.[77]
All his published lithographic sketches are of the greatest value, wholly unrivaled in power of composition, and in love and feeling of architectural subject. His somewhat mannered linear execution, though not to be imitated in your own sketches from Nature, may be occasionally copied, for discipline's sake, with great advantage: it will give you a peculiar steadiness of hand, not quickly attainable in any other way; and there is no fear of your getting into any faultful mannerism as long as you carry out the different modes of more delicate study above recommended.
If you are interested in architecture, and wish to make it your chief study, you should draw much from photographs of it; and then from the architecture itself, with the same completion of detail and gradation, only keeping the shadows of due paleness,—in photographs they are always about four times as dark as they ought to be,—and treat buildings with as much care and love as artists do their rock foregrounds, drawing all the moss, and weeds, and stains upon them. But if, without caring to understand architecture, you merely want the picturesque character of it, and to be able to sketch it fast, you cannot do better than take Prout for your exclusive master; only do not think that you are copying Prout by drawing straight lines with dots at the end of them. Get first his "Rhine," and draw the subjects that have most hills, and least architecture in them, with chalk on smooth paper, till you can lay on his broad flat tints, and get his gradations of light, which are very wonderful; then take up the architectural subjects in the "Rhine," and draw again and again the groups of figures, etc., in his "Microcosm," and "Lessons on Light and Shadow." After that, proceed to copy the grand subjects in the "Sketches in Flanders and Germany;" or "in Switzerland and Italy," if you cannot get the Flanders; but the Switzerland is very far inferior. Then work from Nature, not trying to Proutize Nature, by breaking smooth buildings into rough ones, but only drawing what you see, with Prout's simple method and firm lines. Don't copy his colored works. They are good, but not at all equal to his chalk and pencil drawings; and you will become a mere imitator, and a very feeble imitator, if you use color at all in Prout's method. I have not space to explain why this is so, it would take a long piece of reasoning; trust me for the statement.
2. John Lewis.
His sketches in Spain, lithographed by himself, are very valuable. Get them, if you can, and also some engravings (about eight or ten, I think, altogether) of wild beasts, executed by his own hand a long time ago; they are very precious in every way. The series of the "Alhambra" is rather slight, and few of the subjects are lithographed by himself; still it is well worth having.
But let no lithographic work come into the house, if you can help it, nor even look at any, except Prout's, and those sketches of Lewis's.
