The identity of history is equally intrinsic, the diversity equally obvious. There is, at the surface, infinite variety of things; at the centre there is simplicity of cause. How many are the acts of one man in which we recognize the same character! Observe the sources of our information in respect to the Greek genius. We have the civil history of that people, as Herodotus, Thucydides, Xenophon, and Plutarch have given it; a very sufficient account of what manner of persons they were and what they did. We have the same national mind expressed for us again in their literature, in epic and lyric poems, drama, and philosophy; a very complete form. Then we have it once more in their architecture, a beauty as of temperance itself, limited to the straight line and the square,—a builded geometry. Then we have it once again in sculpture, the “tongue on the balance of expression,” a multitude of forms in the utmost freedom of action and never transgressing the ideal serenity; like votaries performing some religious dance before the gods, and, though in convulsive pain or mortal combat, never daring to break the figure and decorum of their dance. Thus of the genius of one remarkable people we have a fourfold representation: and to the senses what more unlike than an ode of Pindar, a marble centaur, the peristyle of the Parthenon, and the last actions of Phocion?

Every one must have observed faces and forms which, without any resembling feature, make a like impression on the beholder. A particular picture or copy of verses, if it do not awaken the same train of images, will yet superinduce the same sentiment as some wild mountain walk, although the resemblance is nowise obvious to the senses, but is occult and out of the reach of the understanding. Nature is an endless combination and repetition of a very few laws. She hums the old well-known air through innumerable variations.

Nature is full of a sublime family likeness throughout her works, and delights in startling us with resemblances in the most unexpected quarters. I have seen the head of an old sachem of the forest which at once reminded the eye of a bald mountain summit, and the furrows of the brow suggested the strata of the rock. There are men whose manners have the same essential splendor as the simple and awful sculpture on the friezes of the Parthenon and the remains of the earliest Greek art. And there are compositions of the same strain to be found in the books of all ages. What is Guido’s Rospigliosi Aurora but a morning thought, as the horses in it are only a morning cloud? If any one will but take pains to observe the variety of actions to which he is equally inclined in certain moods of mind, and those to which he is averse, he will see how deep is the chain of affinity.
