masters, such as Titian, Tintoretto, and Giovanni Bellini, men who came a hundred years afterwards. It may very possibly be that the pigment which painters used then was purer and less adulterated. Certainly one sees in the various schools all over the world that the older the pictures are the better preserved they are. Age never improves a picture--unless, indeed, it is an extremely bad one, when time serves as a thin veil. [Illustration: CANAL PRIULI] Undoubtedly these great colourists, the Venetians, influenced the various schools of painters all over the world, and are still influencing them. Originally they worked for the churches, and colour was used exactly as music was used--to appeal to the senses, to the emotions: to influence the people, to teach them biblical stories and parables. It also educated the people to understand painting and to feel the need of it in their daily lives. At about this time the Renaissance began to express itself, not only in poetry and other literature, but also in paintings; and it found clearer utterance in Venice than elsewhere. The conditions at this time were perfect for the development of art. Venice at that period lent herself to art. She was at peace with the whole world, and she was prosperous. The people were joyous, gay, and light-hearted. They longed for everything that made life pleasant. Naturally, they wanted colour. And Venice was not affected by that wave of science which swept over the rest of Italy. The Venetians were not at all absorbed in literature and archæology. They wanted merely to be joyous. This was an ideal atmosphere for the painter. Such a condition of things could not but create a fine artistic period. The painter is not concerned with science and learning, or should not be. Such a condition of mind would result in feeble, academical work--in struggling to tell a story with his medium, instead of producing a beautiful design. That is partly why the Venetian school has had such a strong influence on art, even until the present day. The conditions were perfect for the development of art, because the patrons were capable of appreciating beautiful form and beautiful colour. Because the public would have it, this new school of painters appeared. The demand was created, and the supply came.
