Brunelleschi and Ghiberti in Florence

 Filippo Brunelleschi (1377 – April 15, 1446) was one of the foremost architects and engineers of the Italian Renaissance. All of his principal works are in Florence, Italy. As explained by Antonio Manetti, who knew Brunelleschi and who wrote his biography, Brunelleschi "was granted such honors as to be buried in the Basilica di Santa Maria del Fiore, and with a marble bust, which they say was carved from life, and placed there in perpetual memory with such a splendid epitaph.

Ghiberti first became famous when he won the 1401 competition for the first set of bronze doors for the Baptistery of the cathedral in Florence. Brunelleschi was the runner up. The original plan was for the doors to depict scenes from the Old Testament, and the trial piece was the sacrifice of Isaac. However, the plan was changed to depict scenes from the New Testament, instead.

To carry out this commission, he set up a large workshop in which many artists trained, including Donatello, Masolino, Michelozzo, Uccello, and Antonio Pollaiuolo. Ghiberti had re-invented the lost-wax casting (cire perdute) of bronze-casting as it was used by the ancient Romans. This made his workshop so special to young artists.
