But that is wrong.

Ghiberti won his spurs with the doors on the north side, at which comparatively few persons look.

The famous doors opposite the Duomo were commissioned many years later, when his genius was acknowledged and when he had become so accomplished as to do what he liked with his medium.

Before, however, coming to Ghiberti, we ought to look at the work of an early predecessor but for whom there might have been no Ghiberti at all; for while Ghiberti was at work with his assistants on these north doors, between 1403 and 1424, the place which they occupy was filled by those executed seventy years earlier by Andrea Pisano (1270-1348), possibly from Giotto's designs, which are now at the south entrance, opposite the charming little loggia at the corner of the Via Calzaioli, called the Bigallo.

These represent twenty scenes in the life of S.John the Baptist, and below them are eight figures of cardinal and Christian virtues, and they employed their sculptor from 1330 to 1336.
