Hair in waves and ringlets abounds upon his head, so pure and delicate in design that it surpasses feminine beauty and gives the idea of a type superior to all that man can dream of; his eyes are not turned towards the group that he is pointing at, for he has no need to look in order to see, and even if he did not have wings on his shoulders, we should not be deceived regarding his nature. A divine indifference is depicted upon his charming face, and almost a smile lurks in the corners of his lips. He accomplishes the commission given him by the Eternal with an impassible serenity.
Assuredly no virgin, no woman, ever had a more beautiful face; but the most manly spirit and the most dominating intelligence shine in those dark eyes, fixed vaguely upon the spectator who seeks to penetrate their mystery.
We know how difficult it is to paint children. The scarcely settled forms of the earliest age lend themselves awkwardly to art expression. In the little Saint John of the _Madonna of the Rocks_, Leonardo da Vinci has solved this problem with his accustomed superiority. The drawn-up position of the child, who presents several portions of his body foreshortened, is full of grace, a grace sought-for and rare, like everything else that the sublime artist ever did, but natural, nevertheless. It is impossible to find anything more finely modelled than this head with its chubby dimpled cheeks, than those plump little round arms, than the body crossed with rolls of fat, and those legs half folded in the sod. The shadow advances towards the light by gradations of infinite delicacy and gives an extraordinary relief to the figure.
Half enveloped in transparent gauze, the divine _Bambino_ kneels, joining his hands as if he were already conscious of his mission and understood the gesture which the little Saint John repeats after the angel.
With regard to the colour, if in becoming smoked it has lost its proper value, it has retained a harmony preferred by delicate minds for the freshness and brilliancy of its shadows. The tones have deadened in such perfect sympathy that the result is a kind of neutral, abstract, ideal, and mysterious tint which clothes the forms like a celestial veil and sets them apart from terrestrial realities.
