Egyptian painters laid on broad, flat, uniform washes of colour; they did not paint in our sense of the term; they illuminated. Just as in drawing they reduced everything to lines, and almost wholly suppressed the internal modelling, so in adding colour they still further simplified their subject by merging all varieties of tone, and all play of light and shadow, in one uniform tint. Egyptian painting is never quite true, and never quite false. Without pretending to the faithful imitation of nature, it approaches nature as nearly as it may; sometimes understating, sometimes exaggerating, sometimes substituting ideal or conventional renderings for strict realities. Water, for instance, is always represented by a flat tint of blue, or by blue covered with zigzag lines in black. The buff and bluish hues of the vulture are translated into bright red and vivid blue. The flesh-tints of men are of a dark reddish brown, and the flesh-tints of women are pale yellow. The colours conventionally assigned to each animate and inanimate object were taught in the schools, and their use handed on unchanged from generation to generation. Now and then it happened that a painter more daring than his contemporaries ventured to break with tradition. In the Sixth Dynasty tombs at Deir el Gebrawî, there are instances where the flesh tint of the women is that conventionally devoted to the depiction of men. At Sakkarah, under the Fifth Dynasty, and at Abû Simbel, under the Nineteenth Dynasty, we find men with skins as yellow as those of the women; while in the tombs of Thebes and Abydos, about the time of Thothmes IV. and Horemheb, there occur figures with flesh-tints of rose- colour.[41] It must not, however, be supposed that the effect produced by this artificial system was grating or discordant. Even in works of small size, such as illuminated MSS. of _The Book of the Dead_, or the decoration of mummy-cases and funerary coffers, there is both sweetness and harmony of colour. The most brilliant hues are boldly placed side by side, yet with full knowledge of the relations subsisting between these hues, and of the phenomena which must necessarily result from such relations. They neither jar together, nor war with each other, nor extinguish each other. On the contrary, each maintains its own value, and all, by mere juxtaposition, give rise to the half-tones which harmonise them.
