The first of the great personalities in Florentine painting was Giotto. Although he affords no exception to the rule that the great Florentines exploited all the arts in the endeavour to express themselves, he, Giotto, renowned as architect and sculptor, reputed as wit and versifier, differed from most of his Tuscan successors in having peculiar aptitude for the essential in painting as an art.
But before we can appreciate his real value, we must come to an agreement as to what in the art of figure-painting—the craft has its own altogether diverse laws—is the essential; for figure-painting, we may say at once, was not only the one pre-occupation of Giotto, but the dominant interest of the entire Florentine school.
