The "Gates of Paradise" are surmounted by a (copy of a) group of statues portraying the "Baptism of Christ" by Andrea Sansovino. The originals are in the Museo dell'Opera del Duomo. He then left for Rome to work on a new commission, leaving these statues unfinished. Work on these statues was continued much later in 1569 by Vincenzo Danti, a sculptor from the school of Michelangelo. At his death in 1576 the group was almost finished. The group was finally completed with the addition of an angel by Innocenzo Spinazzi in 1792.
