Various are the shapes in which Composition embodies its subject and presents it to our eye. The cone or pyramid, the globe, the grape, flame and stream, the circle and its segments, lend their figure to elevate, concentrate, round, diffuse themselves or undulate in its masses. It towers in the Apollo, it darts its flame forward in the warrior of Agasias, its lambent spires wind upward with the Laocoon; it inverts the cone in the Hercules of Glycon, it doubles it or undulates in Venus and the Graces. In the bland central light of a globe imperceptibly gliding through lucid demi-tints into rich reflected shades, it composes the spell of Correggio, and entrances like a delicious dream; whilst like a torrent it rushes from the hand of Tintorett over the trembling canvass in enormous wings of light and shade, and sweeps all individual importance in general effects. But whether its groups be imbrowned on a lucid sky, or emerge from darkness, whether it break like a meridian sun on the reflected object with Rubens, or from Rembrandt, flash on it in lightning, whatever be its form or its effect, if it be more or less than what it ought to be--a vehicle, if it branch not out of the subject as the produce of its root, if it do not contain all that distinguishes it from other subjects, if it leave out aught that is characteristic and exclusively its own, and admit what is superfluous or common-place--it is no longer composition, it is grouping only, an ostentatious or useless scaffolding about an edifice without a base; such was not the Composition of Raffaello. The leading principle of Raffaello's composition is that simple air, that artlessness which persuades us that his figures have been less composed by skill than grouped by Nature; that the fact must have happened as we see it represented. Simplicity taught him to grasp his subject, propriety to give it character and form, and perspicuity to give it breadth and place. The School of Athens in the Vatican, the Death of Ananias, and the Sacrifice at Lystra, among the Cartoons, may serve as instances. A metaphysical composition, if it be numerous, will be oftener mistaken for dilapidation of fragments than regular distribution of materials. The School of Athens communicates to few more than an arbitrary assemblage of speculative groups. Yet if the subject be the dramatic representation of Philosophy, as it prepares for active life, the parts of the building are not connected with more regular gradation than those groups. Archimedes and Pythagoras, Plato and Socrates, Aristotle and Democritus, Epictetus, Diogenes and Aristippus, in different degrees of characteristic modes, tell one great doctrine, that, fitted by physical and intellectual harmony, man ascends from himself to society, from society to God. For this, group balances group, action is contrasted by repose, each weight has its counterpoise; unity and variety shed harmony over the whole.
