To produce such effects at all requires all the resources of painting, with its power of indirect expression, of subordinate but significant detail, its atmosphere, its foregrounds and backgrounds. To produce them in a pre-eminent degree requires all the resources of poetry, language in its most purged form, its remote associations and suggestions, its double and treble lights. These appliances sculpture cannot command. In it, therefore, not the special situation, but the type, the general character of the subject to be delineated, is all-important. In poetry and painting, the situation predominates over the character; in sculpture, the character over the situation. Excluded by the proper limitation of its material from the development of exquisite situations, it has to choose from a select number of types intrinsically interesting-- interesting, that is, independently of any special situation into which they may be thrown. Sculpture [216] finds the secret of its power in presenting these types, in their broad, central, incisive lines. This it effects not by accumulation of detail, but by abstracting from it. All that is accidental, all that distracts the simple effect upon us of the supreme types of humanity, all traces in them of the commonness of the world, it gradually purges away.
Works of art produced under this law, and only these, are really characterised by Hellenic generality or breadth. In every direction it is a law of restraint. It keeps passion always below that degree of intensity at which it must necessarily be transitory, never winding up the features to one note of anger, or desire, or surprise. In some of the feebler allegorical designs of the middle age, we find isolated qualities portrayed as by so many masks; its religious art has familiarised us with faces fixed immovably into blank types of placid reverie. Men and women, again, in the hurry of life, often wear the sharp impress of one absorbing motive, from which it is said death sets their features free. All such instances may be ranged under the grotesque; and the Hellenic ideal has nothing in common with the grotesque. It allows passion to play lightly over the surface of the individual form, losing thereby nothing of its central impassivity, its depth and repose. To all but the highest culture, the reserved faces of the gods will ever have something of insipidity.
