race upon it, and we probably shall have great creations, whether the people are Christian or Pagan. So that Art seems to be a human creation, rather than a divine inspiration. It is the result of genius, stimulated by circumstances and directed to the contemplation of ideal excellence. Much has been written on those principles upon which Art is supposed to be founded, but not very satisfactorily, although great learning and ingenuity have been displayed. It is difficult to conceive of beauty or grace by definitions,---as difficult as it is to define love or any other ultimate sentiment of the soul. "Metaphysics, mathematics, music, and philosophy," says Cleghorn, "have been called in to analyze, define, demonstrate, or generalize," Great critics, like Burke, Alison, and Stewart, have written interesting treatises on beauty and taste. "Plato represents beauty as the contemplation of the mind. Leibnitz maintained that it consists in perfection. Diderot referred beauty to the idea of relation. Blondel asserted that it was in harmonic proportions. Leigh speaks of it as the music of the age." These definitions do not much assist us. We fall back on our own conceptions or intuitions, as probably did Phidias, although Art in Greece could hardly have attained such perfection without the aid which poetry and history and philosophy alike afforded. Art can flourish only as the taste of the people becomes cultivated, and by the assistance of many kinds of knowledge. The mere contemplation of Nature is not enough. Savages have no art at all, even when they live amid grand mountains and beside the ever-changing sea. When Phidias was asked how he conceived his Olympian Jove, he referred to Homer's poems. Michael Angelo was enabled to paint the saints and sibyls of the Sistine Chapel from familiarity with the writings of the Jewish prophets. Isaiah inspired him as truly as Homer inspired Phidias. The artists of the age of Phidias were encouraged and assisted by the great poets, historians, and philosophers who basked in the sunshine of Pericles, even as the great men in the Court of Elizabeth derived no small share of their renown from her glorious appreciation. Great artists appear in clusters, and amid the other constellations that illuminate the intellectual heavens. They all mutually assist each other. When Rome lost her great men, Art declined. When the egotism of Louis XIV. extinguished genius, the great lights in all departments disappeared. So Art is indebted not merely to the contemplation of ideal beauty, but to the influence of great ideas permeating society,--such as when the age of Phidias was kindled with the great thoughts of Socrates, Democritus, Thucydides, Euripides, Aristophanes, and others, whether contemporaries or not; a sort of Augustan or Elizabethan age, never to appear but once among the same people.
