All things pass away, and during the centuries of disruption which followed the VIth dynasty the old style ran down to an incredible coarseness and clumsy copying. At the close of the XIth dynasty a revival took place. Like all great developments of art it rose with extraordinary rapidity, and within a generation or two the new movement was fully grown. Its characteristic was the use of very low relief, with faint but perfectly clear outlines (see fig. 6). It was the style of a school, and not that of Nature. A regular course of artistic training is described by an artist; first was taught the positions of figures in slow action, then the differences of male and female figures, next mythological subjects, and lastly, the attitudes of rapid action. This mechanical training naturally went with elaboration of detail. The minute lining over large masses of hair, the carving of every bead of a necklace, were the outcome of scholastic training. The artificial reduction of figures in the round to a very delicate variation of planes in low relief was according to the same system. The whole works of the XIIth dynasty are beautiful, reserved, and pleasing, with a clearness and finish which appeals to a sense of orderly perfection. They have neither the grandeur of what went before nor the grace of what followed them. [Illustration: THE PERIODS OF ART 7. XVIIIth dynasty 8. XIXth dynasty 9. Saite (XXVI) 10. Ptolemaic] The XVIIIth and XIXth dynasties are the most popularly known age of the art. The profusion of remains, their accessibility at Thebes, and the more intimate style of the designs, have led to their general acceptance as typical. This position must not be allowed in a wider knowledge of the subject. The whole level of art of the XVIIIth dynasty is as much below that of the XIIth, as the style of the XIIth is below that of the IVth dynasty. The scholastic work of the XIIth is followed by a treatment which is almost always conventional in the XVIIIth; and the XIXth dynasty shows merely a degradation of what preceded it. At the close of the XVIIth dynasty there emerges from the turmoil of the Hyksos barbarism a rude but lively style of drawing, with sculpture of clumsy figures and badly-formed hieroglyphs. Stepping into the XVIIIth dynasty we meet with stiff and rather heavy statuettes, the female figures, however, showing the dawn of the seductive grace which followed. Little can be said to have changed in ideals since the XIIth dynasty, until the Asiatic conquests altered the civilisation of Egypt. Thothmes I and III brought back thousands of Syrian captives, many of whom were selected for their beauty and their artistic ability; their work and their influence transformed the art, and the ideal became that of a light, graceful, fascinating type which posed much and suggested more.
