In H, I have introduced a straight line into our initial scribble, and this somewhat increases the difficulties of relating them. But by drawing 7-8 and 9-10 radiating from 1-2, we have introduced this straight line to 5-6. For although 5-6 and 9-10 do not radiate from the same point, they are obviously in sympathy. It is only a short part of the line at the end marked 5 that is out of sympathy, and had 5-6 taken the course of the dotted line, it would have radiated from the same point as 9-10. We still have line 3-4 to account for. But by drawing 11-12 we bring it into relationship with 5-6, and so by stages through 9-10 and 7-8 to the original straight line 1-2. Line 13-14, by being related to 3-4, 11-12, and also 5-6, still further harmonises the group, and the remainder echo 5-6 and increase the dominant swing. At L masses have been introduced, covering crossing lines, and we have a basis for a composition.
In Diagram I lines have been drawn as before, at random, but two of them are straight and at right angles, the longer being across the-centre of the panel. The first thing to do is to trick the eye out of knowing that this line is in the centre by drawing others parallel to it, leading the eye downwards to line 9-10, which is now much more important than 1-2 and in better proportion with the height of the panel. The vertical line 3-4 is rather stark and lonely, and so we' introduce two more verticals at 11-12 and 13-14, which modify this, and with another two lines in sympathy with 5-6 and leading the eye back to the horizontal top of the panel, some sort of unity is set up, the introduction of some masses completing the scheme at M.
There is a quality of sympathy set up by certain line relationships about which it is important to say something. Ladies who have the instinct for choosing a hat or doing their hair to suit their face instinctively know something of this; know that certain things in their face are emphasised by certain forms in their hats or hair, and the care that has to be taken to see that the things thus drawn attention to are their best and not their worst points.
The principle is more generally understood in relation to colour; everybody knows how the blueness of blue eyes is emphasised by a sympathetic blue dress or touch of blue on a hat, &c. But the same principle applies to lines. The qualities of line in beautiful eyes and eyebrows are emphasised by the long sympathetic curve of a picture hat, and the becoming effect of a necklace is partly due to the same cause, the lines being in sympathy with the eyes or the oval of the face, according to how low or high they hang. The influence of long lines is thus to "pick out" from among the lines of a face those with which they are in sympathy, and thus to accentuate them.
To illustrate this, on page 178 [Transcribers Note: [Plate XLII]] is reproduced "The Portrait of the Artist's Daughter," by Sir Edward Burne-Jones.
The two things that are brought out by the line arrangement in this portrait are the beauty of the eyes and the shape of the face. Instead of the picture hat you have the mirror, the widening circles of which swing round in sympathy with the eyes and concentrate the attention on them. That on the left (looking at the picture) being nearest the centre, has the greatest attention concentrated upon it, the lines of the mirror being more in sympathy with this than the other eye, as it is nearer the centre. If you care to take the trouble, cut a hole in a piece of opaque paper the size of the head and placing it over the illustration look at the face without the influence of these outside lines; and note how much more equally divided the attention is between the two eyes without the emphasis given to the one by the mirror. This helps the unity of impression, which with both eyes realised to so intense a focus might have suffered. This mirror forms a sort of echo of the pupil of the eye with its reflection of the window in the left-hand corner corresponding to the high light, greatly helping the spell these eyes hold.
