As to the limitations that arise from the material we may be working in, we must remember that all material offers certain difficulties to be overcome, and certain facilities to be made the most of. Up to a certain point you must be the master of your material, but you must never be so much the master as to turn it surly, so to say. You must not make it your slave, or presently you will be a slave also. You must master it so far as to make it express a meaning, and to serve your aim at beauty. You may go beyond that necessary point for your own pleasure and amusement, and still be in the right way; but if you go on after that merely to make people stare at your dexterity in dealing with a difficult thing, you have forgotten art along with the rights of your material, and you will make not a work of art, but a mere toy; you are no longer an artist, but a juggler. The history of the arts gives us abundant examples and warnings in this matter. First clear steady principle, then playing with the danger, and lastly falling into the snare, mark with the utmost distinctness the times of the health, the decline, and the last sickness of art.
Allow me to give you one example in the noble art of mosaic. The difficulty in it necessary to be overcome was the making of a pure and true flexible line, not over thick, with little bits of glass or marble nearly rectangular. Its glory lay in its durability, the lovely colour to be got in it, the play of light on its faceted and gleaming surface, and the clearness mingled with softness, with which forms were relieved on the lustrous gold which was so freely used in its best days. Moreover, however bright were the colours used, they were toned delightfully by the greyness which the innumerable joints between the tesseræ spread over the whole surface.
Now the difficulty of the art was overcome in its earliest and best days, and no care or pains were spared in making the most of its special qualities, while for long and long no force was put upon the material to make it imitate the qualities of brush-painting, either in power of colour, in delicacy of gradation, or intricacy of treating a subject; and, moreover, easy as it would have been to minimise the jointing of the tesseræ, no attempt was made at it.
But as time went on, men began to tire of the solemn simplicity of the art, and began to aim at making it keep pace with the growing complexity of picture painting, and, though still beautiful, it lost colour without gaining form. From that point (say about 1460), it went on from bad to worse, till at last men were set to work in it merely because it was an intractable material in which to imitate oil-painting, and by this time it was fallen from being a master art, the crowning beauty of the most solemn buildings, to being a mere tax on the craftsmen’s patience, and a toy for people who no longer cared for art. And just such a history may be told of every art that deals with special material.
Under this head of order should be included something about the structure of patterns, but time for dealing with such an intricate question obviously fails me; so I will but note that, whereas it has been said that a recurring pattern should be constructed on a geometrical basis, it is clear that it cannot be constructed otherwise; only the structure may be more or less masked, and some designers take a great deal of pains to do so.
I cannot say that I think this always necessary. It may be so when the pattern is on a very small scale, and meant to attract but little attention. But it is sometimes the reverse of desirable in large and important patterns, and, to my mind, all noble patterns should at least look large. Some of the finest and pleasantest of these show their geometrical structure clearly enough; and if the lines of them grow strongly and flow gracefully, I think they are decidedly helped by their structure not being elaborately concealed.
At the same time in all patterns which are meant to fill the eye and satisfy the mind, there should be a certain mystery. We should not be able to read the whole thing at once, nor desire to do so, nor be impelled by that desire to go on tracing line after line to find out how the pattern is made, and I think that the obvious presence of a geometrical order, if it be, as it should be, beautiful, tends towards this end, and prevents our feeling restless over a pattern.
That every line in a pattern should have its due growth, and be traceable to its beginning, this, which you have doubtless heard before, is undoubtedly essential to the finest pattern work; equally so is it that no stem should be so far from its parent stock as to look weak or wavering. Mutual support and unceasing progress distinguish real and natural order from its mockery, pedantic tyranny.
Every one who has practised the designing of patterns knows the necessity for covering the ground equably and richly. This is really to a great extent the secret of obtaining the look of satisfying mystery aforesaid, and it is the very test of capacity in a designer.
Finally, no amount of delicacy is too great in drawing the curves of a pattern, no amount of care in getting the leading lines right from the first, can be thrown away, for beauty of detail cannot afterwards cure any shortcoming in this. Remember that a pattern is either right or wrong. It cannot be forgiven for blundering, as a picture may be which has otherwise great qualities in it. It is with a pattern as with a fortress, it is no stronger than its weakest point. A failure for ever recurring torments the eye too much to allow the mind to take any pleasure in suggestion and intention.
