The fact is that the twelfth and thirteenth century convention in figure drawing had served its turn well, but was now worn out. Deriving, originally, as we have seen, out of Greek art in its Byzantine form, it had formed a stock on which the artist of the Early Period had been able to graft his own observation and love of nature, but it had now ceased to satisfy and was therefore abandoned. The progress of drawing in other arts, or at all events in sculpture, had taught men to demand something different. The artist of the late thirteenth century, as the last influence of Greek art died out of his work, had undoubtedly neglected grace of form in his enthusiasm for vigorous and naturalistic movement; and, as so often happens when one quality in art is neglected, a reaction had come, in which people demanded that quality above all others. Consequently, the chief effort of the draughtsman of the fourteenth century, if I understand him rightly, was to bring his drawing of form up to the standard required of him, the S-like attitude, for instance, being merely a trick to get a willowy gracefulness into his figures, especially those of women. The same tendency is observable in the drawing of drapery. The drapery of the thirteenth century was entirely conventional in the method in which it was drawn, but it was always in movement and helped the action of the figures. Fourteenth century drapery, on the other hand, is always at rest, or at most sweeping with the slow movement of a figure, but its folds are drawn in a much more advanced manner than before, and seem to bear evidence of a certain amount of direct study of actual drapery, either on the part of the artist or of those whom he was following. The ideal of gracefulness shows itself in a love for long and sweeping folds, as may be seen in Plates XXIV., XXX., XXXI. At first the artist is content to use in his drawing the strong line work of the preceding period, but as the century proceeds this becomes rather more delicate, and he begins to feel his way towards modelling in half-tones. The drapery over the Virgin's knees in Plate XXI. shows this very clearly. [Illustration: PLATE XXVI GRISAILLE PATTERN AND BOSS FROM PLATE XXV] [Sidenote: Neglect of movement.] With this preoccupation with the truer rendering of form, it is perhaps not surprising that the study of action was neglected. The artist had enough to do to draw his figures and drapery in repose without making them move about and do things, and a contributory cause was, no doubt, the weakening of interest already alluded to in the subjects he had to illustrate. This then is why, whereas in the thirteenth century we find a highly conventional rendering of form allied to naturalism in movement, in the fourteenth, conversely, we find conventional poses and movement allied to a more naturalistic rendering of form.
