Nothing overshadows truth so much as authority.

The city is like a great house, and the house in its turn a small city.

The function of the painter is to render... the visible surface so that at a certain distance... and position it appears... like the body itself.

Beauty is the adjustment of all parts proportionately so that one cannot add or subtract or change without impairing the harmony of the whole.

It is very rarely granted even to Nature herself to produce anything absolutely perfect in every part.

I will never tire of recommending the custom, practiced by the best architects, of preparing not only drawings and sketches, but also models of wood or any other material. These... enable us to examine... the work as a whole... and, before continuing any further, to estimate the likely trouble and expense.
