But there is another kind of interest also. Wordsworth says that children are the best philosophers; and in the case of art at any rate there is some truth in what he says, for "this is a general law, that supposing the intellect of the workman the same, the more imitatively complete his art, the less he will mean by it; and the ruder the symbol, the deeper is its intention" (Ruskin's _Lectures on Art_, § 19). The more complete his powers of imitation become, the more intellectual interest he takes in the expression, and the less therefore in the thing meant. What then is the meaning of these early pictures? To answer this question, we must go back to consider what it was that gave the original impulse to the revival of art in Italy. To this revival two circumstances contributed. First, no school of painting can exist until society is comparatively rich, until there is wealth enough to support a class of men with leisure to produce beautiful things. Such an increase of wealth took place at Florence in the thirteenth century: the gay and courteous life of the Florentines at that time was ready for the adornment of art. The particular direction which art took was due to the religious revival, headed by St. Francis and St. Dominic, which occurred at the same time. Churches were everywhere built, and on the church walls frescoes were wanted, alike to satisfy the growing sense of beauty and to assist in teaching Christian doctrine. These early pictures are thus to be considered as a kind of painted preaching. The story of Cimabue's great picture (see No. 565) well illustrates the double origin of the revival of art. It was to its place above the altar in the great Dominican church of Sta. Maria Novella at Florence that the picture was carried in triumphal procession; whilst the fact that a whole city should thus have turned out to rejoice over the completion of a picture, proves "the widespread sensibility of the Florentines to things of beauty, and shows the sympathy which, emanating from the people, was destined to inspire and brace the artist for his work" (Symonds: _Renaissance_, iii. 137).[15] The history of Giotto is no less significant. It was for the walls of the church of St. Francis at Assisi that his greatest work was done. It was there that he at once pondered over the meaning of the Christian faith (with what result is shown by Ruskin in _Fors Clavigera_ and elsewhere), and learned the secret of giving the resemblance of the objects of that faith in painting. Thus, then, we arrive at the second source of interest in these old pictures of Florence--rude and foolish as they sometimes seem. "Those were noble days for the painter, when the whole belief of Christendom, grasped by his own faith, and firmly rooted in the faith of the people round him, as yet unimpaired by alien emanations from the world of classic culture, had to be set forth for the first time in art. His work was then a Bible, a compendium of grave
