About three hundred years elapsed between Giotto's birth and Titian's death, during which the world changed from the rough state of the Middle Age to a very high degree of civilization; and men's eyes grew tired of what they saw all the time, while many of the strong types which had made the change faded away. Men grew more alike, dress grew more alike, thoughts grew more alike. It was the beginning of that overspreading uniformity which we have in our time, which makes it so very easy for any one man to be eccentric, but which makes it so very hard for any one man to be really great. One might say that in those times humanity flowed in very small channels, which a strong man of genius could thwart and direct. But humanity now is a stream so broad that it is almost like an ocean, in which all have similar being, and the big fish come to the surface, and spout and blow and puff without having any influence at all on the tide. There was hardly any such thing possible as eccentricity in Giotto's time. When the dress and manners and language of every little town differed distinctly from those of the nearest village, every man dressed as he pleased, behaved as he had been taught, and spoke the dialect of his native place. There was a certain uniformity among the priesthood, whose long cassock was then the more usual dress of civilians in great cities in times of peace and who spoke Latin among themselves and wrote it, though often in a way that would make a scholar's blood run cold. But there was no uniformity among other classes of men. A fine gentleman who chose to have his cloth tights of several colours, one leg green and one blue, or each leg in quarters of four colours, attracted no attention whatever in the streets; and if one noble affected simple habits and went about in an old leathern jerkin that was rusty in patches from the joints of his armour, the next might dress himself in rich silk and gold embroidery, and wear a sword with a fine enamelled hilt. No one cared, except for himself, and it must have been hard indeed to produce much effect by any eccentricity of appearance. But there was the enormous and constantly changing variety that takes an artist's eye at every turn,--which might make an artist then of a man who nowadays would be nothing but a discontented observer with artistic tastes.
