The building had now risen to such a height that it was a very great inconvenience for anyone who had climbed to the top to descend to the ground, and the builders lost much time in going to eat and drink, and suffered great discomfort in the heat of the day. Filippo therefore made arrangements for eating-houses with kitchens to be opened on the cupola, and for wine to be sold there, so that no one had to leave his labour until the evening, which was convenient for the men and very advantageous for the work. Seeing the work making great progress and succeeding so happily, Filippo had grown so greatly in courage that he was continually labouring, going in person to the furnaces where the bricks were being shaped and demanding to see the clay and to feel its consistency, and insisting on selecting them with his own hand when baked, with the greatest diligence. When the stonecutters were working at the stones, he would look at them to see if they showed flaws and if they were hard, and he would give the men models in wood or wax, or[19] made simply out of turnips; and he would also make iron tools for the smiths. He invented hinges with heads, and hinge-hooks, and he did much to facilitate architecture, which was certainly brought by him to a perfection such as it probably had never enjoyed among the Tuscans. [Footnote 19: To make this passage intelligible, the word "or" has been added in the later editions.] In the year 1423 the greatest possible happiness and rejoicing were prevailing in Florence, when Filippo was chosen as one of the Signori for the quarter of San Giovanni, for May and June, Lapo Niccolini being chosen as Gonfalonier of Justice for the quarter of Santa Croce. And if he is found registered in the Priorista as "Filippo di Ser Brunellesco Lippi," no one need marvel, seeing that he was called thus after his grandfather Lippo, and not "de' Lapi," as he should have been; which method is seen from the said Priorista to have been used in innumerable other cases, as is well known to all who have seen it or who know the custom of those times. Filippo exercised that office and also other magisterial functions that he obtained in his city, wherein he ever bore himself with most profound judgment.
