And first it must be determined what a work of art is. Leaving for a while music and architecture out of consideration, it will be admitted that poetry, painting, and sculpture have one obvious character in common: they are arts of IMITATION. This, says Taine, appears at first sight to be their essential character. It would appear that their great object is to IMITATE as closely as possible. It is obvious that a statue is intended to imitate a living man, that a picture is designed to represent real persons in real attitudes, or the interior of a house, or a landscape, such as it exists in nature. And it is no less clear that a novel or drama endeavours to represent with accuracy real characters, actions, and words, giving as precise and faithful an image of them as possible. And when the imitation is incomplete, we say to the painter, "Your people are too largely proportioned, and the colour of your trees is false"; we tell the sculptor that his leg or arm is incorrectly modelled; and we say to the dramatist, "Never has a man felt or thought as your hero is supposed to have felt and thought." This truth, moreover, is seen both in the careers of individual artists, and in the general history of art. According to Taine, the life of an artist may generally be divided into two parts. In the first period, that of natural growth, he studies nature anxiously and minutely, he keeps the objects themselves before his eyes, and strives to represent them with scrupulous fidelity. But when the time for mental growth ends, as it does with every man, and the crystallization of ideas and impressions commences, then the mind of the artist is no longer so susceptible to new impressions from without. He begins to nourish himself from his own substance. He abandons the living model, and with recipes which he has gathered in the course of his experience, he proceeds to construct a drama or novel, a picture or statue. Now, the first period, says Taine, is that of genuine art; the second is that of mannerism. Our author cites the case of Michael Angelo, a man who was one of the most colossal embodiments of physical and mental energy that the world has ever seen. In Michael Angelo's case, the period of growth, of genuine art, may be said to have lasted until after his sixtieth year. But look, says Taine, at the works which he executed in his old age; consider the Conversion of St. Paul, and the Last Judgment, painted when he was nearly seventy. Even those who are not connoisseurs can see that these frescos are painted by rule, that the artist, having stocked his memory with a certain set of forms, is making use of them to fill out his tableau; that he wantonly multiplies queer attitudes and ingenious foreshortenings; that the lively invention, the grand outburst of feeling, the perfect truth, by which his earlier works are distinguished, have disappeared; and that, if he is still superior to all others, he is nevertheless inferior to himself.
