The marvellous works of these two brothers will bear witness before the world to the extraordinary genius that they possessed; and for their lives, their honourable ways, and their every action, they were held in estimation by all men. Giuliano and Antonio bequeathed to the art of architecture methods that gave the Tuscan Order of building better form than any other architect had yet achieved, and the Doric Order they enriched with better measures and proportions than their predecessors, following the rules and canons of Vitruvius, had been wont to use. They collected in their houses at Florence an infinite number of most beautiful antiquities in marble, which adorned Florence, and still adorn her, no less than those masters honoured themselves and their art. Giuliano brought from Rome the method of casting vaults with such materials as made them ready carved; examples of which may be seen in a room in his own house, and in the vaulting of the Great Hall at Poggio a Cajano, which is still to be seen there. Wherefore we should acknowledge our obligation to their labours, whereby they fortified the dominion of Florence, adorned the city, and gave a name, throughout the many regions where they worked, to Florence and to the intellects of Tuscany, who, to honour their memory, have written to them these verses-- Cedite Romani structores, cedite Graii, Artis, Vitruvi, tu quoque cede parens. Etruscos celebrare viros, testudinis arcus, Urna, tholus, statuae, templa, domusque petunt. FOOTNOTE: [22] A friable volcanic tufa.
