In his aedificiorum generibus omnes sunt faciendae earum symmetriarum rationes, quae sine inpeditione loci fieri poterunt, luminaque, parietum altitudinibus si non obscurabuntur, faciliter erunt explicata; sin autem inpedientur ab angustiis aut aliis necessitatibus, tunc erit ut ingenio et acumine de symmetriis detractiones aut adiectiones fiant, uti non dissimiles veris symmetriis perficiantur venustates.
In buildings of this kind, all the rules of symmetry must be followed, which are allowed by the site, and the windows will be easily arranged unless they are darkened by high walls opposite. But if they are obstructed by the narrowness of the street or by other inconveniences, skill and resource must alter the proportions by decreasing or adding, so that an elegance may be attained in harmony with the proper proportions.
