Neither Luca nor Andrea was in the habit of signing his work, but Giovanni often did so, usually adding the date, probably because other potters had begun to imitate the Robbia ware.

[1] Another work that equalled that anything of his father's, from whom the design of the figures was probably taken, is the washings fountain in the sacristy of the Basilica of Santa Maria Novella at Florence, made in 1497.

[1] Giovanni not only copied the work of Luca and Andrea, but even reproduced in clay the marble sculpture of Antonio del Pollaiuolo, Da Settignano, Verrocchio and others.

At Pisa in the Campo Santo is a relief in Giovanni's later manner dated 1520; it is a Madonna surrounded by angels, with saints below the whole overcrowded with figures and ornaments.

The subjects of this frieze are the Seven Works of Mercy, forming a continuous band of sculpture in high relief, designed in a very broad sculpturesque way, but with somewhat crude colouring.

[1] A large octagonal font of enamelled clay, with pilasters at the angles and panels between them with scenes from the life of John the Baptist, in the church of San Leonardo at Cerreto Guidi, is a work of the school of Giovanni; the reliefs are pictorial in style and coarse in execution.
