This was the case in the time of our fathers with the Florentine Cecca, into whose hands there came many highly honourable works in his day; and in these he acquitted himself so well, toiling in the service of his country with economy and with great satisfaction to his fellow-citizens, that his ingenious and industrious labours have made him famous and illustrious among the number of distinguished and renowned craftsmen. It is said that in his youth Cecca was a very good carpenter, and that he had concentrated all his powers on seeking to solve the difficulties connected with engines, and how to make machines for assaulting walls in war--scaling-ladders for climbing into cities, battering-rams for breaching fortifications, defences for protecting soldiers in the attack, and everything that could injure his enemies and assist his friends--wherefore, being a person of the greatest utility to his country, he well deserved the permanent provision that the Signoria of Florence gave him. For this reason, when there was no war going on, he would go through the whole territory inspecting the fortresses and the walls of cities and townships, and, if any were weak, he would provide them with designs for ramparts and everything else that was wanting.
