The figures which are between you and the light, if they be at a distance, will appear dark on a light background, and the lower part of their legs near the ground will be least visible, because there the dust is coarsest and densest [19].  And if you introduce horses galloping outside the crowd, make the little clouds of dust distant from each other in proportion to the strides made by the horses; and the clouds which are furthest removed from the horses, should be least visible; make them high and spreading and thin, and the nearer ones will be more conspicuous and smaller and denser [23].  The air must be full of arrows in every direction, some shooting upwards, some falling, some flying level.  The balls from the guns must have a train of smoke following their flight.  The figures in the foreground you must make with dust on the hair and eyebrows and on other flat places likely to retain it.  The conquerors you will make rushing onwards with their hair and other light things flying on the wind, with their brows bent down,
