The Duomo, as it is usually pronounced, was started in 1296 in the Gothic style by architect, Arnolfo di Cambio and its structure finished in 1436 with the dome engineered by Filippo Brunelleschi. The work continued on the church in 1349 under the observation of different architects, beginning with Francesco Talenti, who had done the campanile and enlarged the total project to include the apse and the adjacent chapels. On 19 August 1418, the Arte della Lana publicized a structural design competition for founding Neri's dome. The two main competitors were two master goldsmiths,Lorenzo Ghiberti and Filippo Brunelleschi, who has the support of Cosimo de Medici. Finally, Brunelleschi won and received the commission. The noticeable point is that it was the first 'octagonal' dome in history to be built without a temporary wooden supporting frame. The building of such a masonry dome posed many technical problems. Brunelleschi decided to follow the pantheon strategy but all the information about its construction was forgotten. A wooden form had held the Pantheon dome aloft while its concrete set, but the problem with the neri’s desing was the height and breadth of the dome which was 52 meters above the floor and also spanning 44 meters. Brunelleschi had to construct the dome out of bricks, because of to its light weight compared to stone and easier to form, and with nothing under it during construction. He constructed a wooden and brick model and still displayed in the Museo dell'Opera del Duomo. The model made as a reference for the employees, but was intentionally undone, to ensure Brunelleschi's control over the construction. Brunelleschi's solutions were ingenious. The spreading problem was solved by a set of four
