In the earlier history of art it was not so necessary to insist on the limitations imposed by different mediums. With their more limited knowledge of the phenomena of vision, the early masters had not the same opportunities of going astray in this respect. But now that the whole field of vision has been discovered, and that the subtlest effects of light and atmosphere are capable of being represented, it has become necessary to decide how far complete accuracy of representation will help the particular impression you may intend your picture or drawing to create. The danger is that in producing a complete illusion of representation, the particular vitality of your medium, with all the expressive power it is capable of yielding, may be lost.
Perhaps the chief difference between the great masters of the past and many modern painters is the neglect of this principle. They represented nature in terms of whatever medium they worked in, and never overstepped this limitation. Modern artists, particularly in the nineteenth century, often attempted to copy nature, the medium being subordinated to the attempt to make it look like the real thing. In the same way, the drawings of the great masters were drawings. They did not attempt anything with a point that a point was not capable of expressing. The drawings of many modern artists are full of attempts to express tone and colour effects, things entirely outside the true province of drawing. The small but infinitely important part of nature that pure drawing is capable of conveying has been neglected, and line work, until recently, went out of fashion in our schools.
There is something that makes for power in the limitations your materials impose. Many artists whose work in some of the more limited mediums is fine, are utterly feeble when they attempt one with so few restrictions as oil paint. If students could only be induced to impose more restraint upon themselves when they attempt so difficult a medium as paint, it would be greatly to the advantage of their work. Beginning first with monochrome in three tones, as explained in a former chapter, they might then take for figure work ivory black and Venetian red. It is surprising what an amount of colour effect can be got with this simple means, and how much can be learned about the relative positions of the warm and cold colours. Do not attempt the full range of tone at first, but keep the darks rather lighter and the lights darker than nature. Attempt the full scale of tone only when you have acquired sufficient experience with the simpler range, and gradually add more colours as you learn to master a few. But restraints are not so fashionable just now as unbridled licence. Art students start in with a palette full of the most amazing colours, producing results that it were better not to discuss. It is a wise man who can discover his limitations and select a medium the capacities of which just tally with his own. To discover this, it is advisable to try many, and below is a short description of the chief ones used by the draughtsman. But very little can be said about them, and very little idea of their capacities given in a written description; they must be handled by the student, and are no doubt capable of many more qualities than have yet been got out of them.
Lead Pencil
This well-known medium is one of the most beautiful for pure line work, and its use is an excellent training to the eye and hand in precision of observation. Perhaps this is why it has not been so popular in our art schools lately, when the charms of severe discipline are not so much in favour as they should be. It is the first medium we are given to draw with, and as the handiest and most convenient is unrivalled for sketch-book use.
It is made in a large variety of degrees, from the hardest and greyest to the softest and blackest, and is too well known to need much description. It does not need fixing.
For pure line drawing nothing equals it, except silver point, and great draughtsmen, like Ingres, have always loved it. It does not lend itself so readily to any form of mass drawing. Although it is sometimes used for this purpose, the offensive shine that occurs if dark masses are introduced is against its use in any but very lightly shaded work.
