From the seven reliefs, depicting Liberal Arts, in the lower register of the north side of the Campanile, only the first two, depicting Sculpture and Painting, are attributed to Andrea Pisano. The others, carried out by Luca della Robbia, were added later, after removal of the raised passageway between the campanile and the cathedral.

The reliefs in the upper register depict six of the Seven Sacraments. The missing sacrament, Holy Orders, has survived as only a small fragment. The reliefs are attributed to Maso di Banco, known primarily as a painter.
