Among the most distinguished scholars of Niccola Pisano's tradition must now be mentioned Andrea da Pontadera, called Andrea Pisano, who carried the manner of his master to Florence, and helped to fulfil the destiny of Italian sculpture by submitting it to the rising art of painting. Under the direction of Giotto he carved statues for the Campanile and the façade of S. Maria del Fiore; and in the first gate of the Baptistery, he bequeathed a model of bas-relief in bronze, which largely influenced the style of masters in the fifteenth century. To overpraise the simplicity and beauty of design, the purity of feeling, and the technical excellence of Andrea's bronze-work, would be difficult. Many students will always be found to prefer his self-restraint and delicacy to the more florid manner of Ghiberti.[70] What we chiefly observe in this gate is the control exercised by the sister art of painting over his mode of conception and treatment. If Giovanni Pisano developed the dramatic and emphatic qualities of Gothic sculpture, Andrea was attracted to its allegories; if Giovanni infused romantic vehemence of feeling into the frigid classicism of his father, Andrea diverged upon another track of picturesque delineation. A new sun had now arisen in the heavens of art. This was the sun of Giotto, whose genius, eminently pictorial, brought the Italians to a true sense of their aesthetical vocation, illuminating with its brightness the elder and more technically finished craft of the stone-carver. Sculpture, which in the school of Niccola Pisano had been subordinate to architecture, became a sub-species of painting in the hands of Andrea.
