(active c. 1290-1349 in Pisa)
Giotto was appointed Capomaestro of the Florence Cathedral in 1334. He probably confined himself to designing the separate Campanile which stands like a tower beside the façade. In fact Giotto's Campanile is not entirely as he designed it. Only the lower story of the bell tower was realized from Giotto's design. The next three stories were executed by Andrea Pisano Giotto's successor as capomaestro. The remainder was completed by Francesco Talenti in the 1350s.
