Classic architectural treatise

De re aedificatoria (On the Art of Building) is a classic architectural treatise written by Leon Battista Alberti between 1443 and 1452. Although largely dependent on Vitruvius's De architectura, it was the first theoretical book on the subject written in the Italian Renaissance, and in 1485 it became the first printed book on architecture. It was followed in 1486 with the first printed edition of Vitruvius.

In Book Nine, Alberti presents his comments about aesthetic theory and beauty which Borsi summarizes on page 234 of his Alberti book stating: "In short, what are the elements that constitute beauty? (Or what elements derive from each particular kind of beauty?) The question is a difficult one." Quoting Alberti, Borsi presents Alberti as stating: "For whatever that property be which is chosen from the whole number and nature of the several parts or attributed to each of them in precise and equal measure, or which must be such as to form a single entity of organism out of a number of parts, binding them together in a just, stable and harmonious manner it must certainly contain within itself the value, I would almost say the essence of all the above mentioned parts with which it is connected or which it compenetrates. Otherwise they would clash and the beauty of the whole be lost. This enquiry and selection is in itself far from easy or obvious. But it is particularly hazardous and difficult in the field we have chosen to enquire into, for architecture consists of so many various parts, and each of these parts requires so many different ornaments, as we have already seen." For Borsi, Alberti is deriving his viewpoint from the Enneads by Plotinus.
