used for the construction of the cupola
by Silvia Messeri
When Leonardo da Vinci, already fascinated by Brunelleschi's genius, arrived as an art apprentice in Florence in 1469 and saw the cupola of the Cathedral of Santa Maria del Fiore, he immediately wanted to study the machines that Filippo Brunelleschi had used in its construction.

The only illustrations of these machines that have survived to this day are the drawings that were carried out by some of the most famous engineers of the Renaissance: Giuliano da Sangallo, Mariano di Jacono, known as Taccola, and Bonaccorso Ghiberti, all of whom were fascinated by the mind that had conceived and created such brilliantly clever devices/ Brunelleschi in fact left no written or drawn illustrations of the machines he used in the construction of the cupola.

Thus we find drawings of Brunelleschi's lifting devices or the revolving crane used to raise the lantern by Leonardo, together with several others by Ghiberti and Sangallo of Brunelleschi's three-speed hoist, while Taccola carried out a view of Brunelleschi's horse-drawn hoist.

All these illustrations can be found in the fascinating catalogue published by Giunti for the Engineers of the Renaissance exhibition and which contains a detailed description of the machines and human inventiveness in one of the most creative periods in the history of mankind.
