A Treatise on Painting

by da Vinci Leonardo

A painter is to be attentive to the motions and actions of men, occasioned by some sudden accident. He must observe them on the spot, take sketches, and not wait till he wants such expression, and then have it counterfeited for him; for instance, setting a model to weep when there is no cause; such an expression without a cause will be neither quick nor natural. But it will be of great use to have observed every action from nature, as it occurs, and then to have a model set in the same attitude to help the recollection, and find out something to the purpose, according to the subject in hand.

Chap. CLVII.—How to represent a Storm.

To form a just idea of a storm, you must consider it attentively in its effects. When the wind blows violently over the sea or land, it removes and carries off with it every thing that is not firmly fixed to the general mass. The clouds must appear straggling and broken, carried according to the direction and the force of the wind, and blended with clouds of dust raised from the sandy shore. Branches and leaves of trees must be represented as carried along by the violence of the storm, and, together with numberless other light substances, scattered in the air. Trees and grass must be bent to the ground, as if yielding to the course of the wind. Boughs must be twisted out of their natural form, with their leaves reversed and entangled. Of the figures dispersed in the picture, some should appear thrown on the ground, so wrapped up in their cloaks and covered with dust, as to be scarcely distinguishable. Of those who remain on their feet, some should be sheltered by and holding fast behind some great trees, to avoid the same fate: others bending to the ground, their hands over their faces to ward off the dust; their hair and their clothes flying straight up at the mercy of the wind.

The high tremendous waves of the stormy sea will be covered with foaming froth; the most subtle parts of which, being raised by the wind, like a thick mist, mix with the air. What vessels are seen should appear with broken cordage, and torn sails, fluttering in the wind; some with broken masts fallen across the hulk, already on its side amidst the tempestuous waves. Some of the crew should be represented as if crying aloud for help, and clinging to the remains of the shattered vessel. Let the clouds appear as driven by tempestuous winds against the summits of lofty mountains, enveloping those mountains, and breaking and recoiling with redoubled force, like waves against a rocky shore. The air should be rendered awfully dark, by the mist, dust, and thick clouds.

Chap. CLVIII.—How to compose a Battle.

First, let the air exhibit a confused mixture of smoke, arising from the discharge of artillery and musquetry, and the dust raised by the horses of the combatants; and observe, that dust being of an earthy nature, is heavy; but yet, by reason of its minute particles, it is easily impelled upwards, and mixes with the air; nevertheless, it naturally falls downwards again, the most subtle parts of it alone gaining any considerable degree of elevation, and at its utmost height it is so thin and transparent, as to appear nearly of the colour of the air. The smoke, thus mixing with the dusty air, forms a kind of dark cloud, at the top of which it is distinguished from the dust by a blueish cast, the dust retaining more of its natural colour. On that part from which the light proceeds, this mixture of air, smoke, and dust, will appear much brighter than on the opposite side. The more the combatants are involved in this turbulent mist, the less distinctly they will be seen, and the more confused will they be in their lights and shades. Let the faces of the musketeers, their bodies, and every object near them, be tinged with a reddish hue, even the air or cloud of dust; in short, all that surrounds them. This red tinge you will diminish, in proportion to their distance, from the primary cause. The groups of figures, which appear at a distance between the spectator and the light, will form a dark mass upon a light ground; and their legs will be more undetermined and lost as they approach nearer to the ground; because there the dust is heavier and thicker.

If you mean to represent some straggling horses, running out of the main body, introduce also some small clouds of dust, as far distant from each other as the leap of the horse, and these little clouds will become fainter, more scanty, and diffused, in proportion to their distance from the horse. That nearest to his feet will consequently be the most determined, smallest, and the thickest of all.

Let the air be full of arrows, in all directions; some ascending, some falling down, and some darting straight forwards. The bullets of the musketry, though not seen, will be marked in their course by a train of smoke, which breaks through the general confusion. The figures in the fore-ground should have their hair covered with dust, as also their eyebrows, and all parts liable to receive it.

The victorious party will be running forwards, their hair and other light parts flying in the wind, their eyebrows lowered, and the motion of every member properly contrasted; for instance, in moving the right foot forwards, the left arm must be brought forwards also. If you make any of them fallen down, mark the trace of his fall on the slippery, gore-stained dust; and where the ground is less impregnated with blood, let the print of men’s feet and of horses, that have passed that way, be marked. Let there be some horses dragging the bodies of their riders, and leaving behind them a furrow, made by the body thus trailed along.

The countenances of the vanquished will appear pale and dejected. Their eyebrows raised, and much wrinkled about the forehead and cheeks. The tip of their noses somewhat divided from the nostrils by arched wrinkles terminating at the corner of the eyes, those wrinkles being occasioned by the opening and raising of the nostrils; the upper lips turned up, discovering the teeth. Their mouths wide open, and expressive of violent lamentation. One may be seen fallen wounded on the ground, endeavouring with one hand to support his body, and covering his eyes with the other, the palm of which is turned towards the enemy. Others running away, and with open mouths seeming to cry aloud. Between the legs of the combatants let the ground be strewed with all sorts of arms; as broken shields, spears, swords, and the like. Many dead bodies should be introduced, some entirely covered with dust, others in part only; let the blood, which seems to issue immediately from the wound, appear of its natural colour, and running in a winding course, till, mixing with the dust, it forms a reddish kind of mud. Some should be in the agonies of death; their teeth shut, their eyes wildly staring, their fists clenched, and their legs in a distorted position. Some may appear disarmed, and beaten down by the enemy, still fighting with their fists and teeth, and endeavouring to take a passionate, though unavailing revenge. There may be also a straggling horse without a rider, running in wild disorder; his mane flying in the wind, beating down with his feet all before him, and doing a deal of damage. A wounded soldier may also be seen falling to the ground, and attempting to cover himself with his shield, while an enemy bending over him endeavours to give him the finishing stroke. Several dead bodies should be heaped together under a dead horse. Some of the conquerors, as having ceased fighting, may be wiping their faces from the dirt, collected on them by the mixture of dust with the water from their eyes.
