3In this book I have explained, as they have occurred to me, the methods of making colours for painting, so that they may be durable and appropriate. Thus, in seven books, are methodically laid down all the rules that relate to the perfection and convenience of buildings. In the following book I shall treat of water, how it is to be found and conveyed to any place; as also how to ascertain its salubrity, and fitness for the purposes to which it is to be applied.
3In this book I have written down, so far as I could recall them, the methods and means of attaining durability in polished finishings, how pictures that are appropriate should be made, and also the natural qualities of all the colours. And so, having prescribed in seven books the suitable principles which should govern the construction of all kinds of buildings, I shall treat in the next of water, showing how it may be found in places where it is wanting, by what method it may be conducted, and by what means its wholesomeness and fitness may be tested.
