86. This is surely a fact to be taken much to heart by our present communities of Liverpool and Manchester. They probably suppose, in their modesty, that lords and clergymen are the proper judges of art, and merchants can only, in the modern phrase, 'know what they like,' or follow humbly the guidance of their golden-crested or flat-capped superiors. But in the great ages of art, neither knight nor pope shows signs of true power of criticism. The artists crouch before them, or quarrel with them, according to their own tempers. To the merchants they submit silently, as to just and capable judges. And look what men these are, who submit. Donatello, Ghiberti, Quercia, Luca! If men like these submit to the merchant, who shall rebel? 87. But the still franker, and surer, judgment of innocent pleasure was awarded them by all classes alike: and the interest of the public was the _final _rule of right,--that public being always eager to see, and earnest to learn. For the stories told by their artists formed, they fully believed, a Book of Life; and every man of real genius took up his function of illustrating the scheme of human morality and salvation, as naturally, and faithfully, as an English mother of to-day giving her children their first lessons in the Bible. In this endeavour to teach they almost unawares taught themselves; the question "How shall I represent this most clearly?" became to themselves, presently, "How was this most likely to have happened?" and habits of fresh and accurate thought thus quickly enlivened the formalities of the Greek pictorial theology; formalities themselves beneficent, because restraining by their severity and mystery the wantonness of the newer life. Foolish modern critics have seen nothing in the Byzantine school but a barbarism to be conquered and forgotten. But that school brought to the art-scholars of the thirteenth century, laws which had been serviceable to Phidias, and symbols which had been beautiful to Homer: and methods and habits of pictorial scholarship which gave a refinement of manner to the work of the simplest craftsman, and became an education to the higher artists which no discipline of literature can now bestow, developed themselves in the effort to decipher, and the impulse to re-interpret, the Eleusinian divinity of Byzantine tradition.
