Construction Begins on Giotto's Belltower in Florence
On the death in 1302 of Arnolfo di Cambio, the first Master of the Works of the Cathedral, and after an interruption of more than thirty years, the celebrated painter Giotto di Bondone was nominated as his successor in 1334.
At that time he was 67 years old. Giotto concentrated his energy on the design and construction of a campanile (bell tower) for the cathedral. He had become an eminent architect, thanks to the growing autonomy of the architect-designer in relation to the craftsmen since the first half of the 13th century. The first stone was laid on 19 July 1334. His design was in harmony with the polychromy of the cathedral, as applied by Arnolfo di Cambio, giving the tower a view as if it were “painted”. In his design he also applied chiaroscuro and some form of perspective instead of a strict linear drawing of the campanile. And instead of a filigree skeleton of a gothic building, he applied a surface of coloured marble in geometric patterns.
When he died in 1337, he had only finished the lower floor with its marble external revetment: geometric patterns of white marble from Carrara, green marble from Prato and red marble from Siena. This lower floor is decorated on three sides with bas-reliefs in hexagonal panels, seven on each side. When the entrance door was enlarged in 1348, two panels were moved to the empty northern side and only much later, five more panels were commissioned from Luca della Robbia in 1437. The number “seven” has a special meaning in Biblical sense: it symbolizes human perfectibility. It is difficult to attribute artistic paternity to these panels, some may be by Giotto himself, the others by Andrea Pisano (or their workshops).
