North Doors of the Florence Baptistery, Relief sculpture entrance at Museo dell'Opera del Duomo, Florence, Italy.

The North Doors are a pair of dark bronze doors now in the Museo dell'Opera del Duomo in Florence, originally made for the Baptistery. Each leaf has a grid of square panels—five rows of two per leaf, twenty in all—with raised relief scenes of small figures. Narrow raised borders separate the panels, and the work is signed "OPVS LAUREN/TII•FLOREN/TINI" above the Nativity and Adoration of the Magi.

Lorenzo Ghiberti began work on these doors in 1403 after winning a competition against other artists of his time, including Brunelleschi. Completion came in 1424 and marked a turning point in Renaissance sculpture.

The panels show different biblical narratives: the upper rows feature evangelists and church fathers, while the lower panels depict episodes from the life of Christ. This arrangement guides the eye from theological foundations down to the concrete events of redemption.

The original doors now rest in the museum, while reproductions stand at the baptistery itself. Visitors wishing to compare both versions should view the replicas at the original site first, then visit the museum.

The frames between the panels are filled with tiny sculpted details: leaves, fruit, animals, and insects enliven the spaces. At each intersection point, small heads of prophets also appear, filling the entire frame with life.
