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.

A painter told me that nobody could draw a tree without in some sort becoming a tree; or draw a child by studying the outlines of its form merely,--but, by watching for a time his motions and plays, the painter enters into his nature and can then draw him at will in every attitude. So Roos "entered into the inmost nature of a sheep." I knew a draughtsman employed in a public survey who found that he could not sketch the rocks until their geological structure was first explained to him. In a certain state of thought is the common origin of very diverse works. It is the spirit and not the fact that is identical. By a deeper apprehension, and not primarily by a painful acquisition of many manual skills, the artist attains the power of awakening other souls to a given activity.

It has been said that "common souls pay with what they do, nobler souls with that which they are." And why? Because a profound nature awakens in us by its actions and words, by its very looks and manners, the same power and beauty that a gallery of sculpture or of pictures addresses.

Civil and natural history, the history of art and of literature, must be explained from individual history, or must remain words. There is nothing but is related to us, nothing that does not interest us,--kingdom, college, tree, horse, or iron shoe,--the roots of all things are in man. Santa Croce and the Dome of St. Peter's are lame copies after a divine model. Strasburg Cathedral is a material counterpart of the soul of Erwin of Steinbach. The true poem is the poet's mind; the true ship is the ship-builder. In the man, could we lay him open, we should see the reason for the last flourish and tendril of his work; as every spine and tint in the sea-shell preexists in the secreting organs of the fish. The whole of heraldry and of chivalry is in courtesy. A man of fine manners shall pronounce your name with all the ornament that titles of nobility could ever add.
