Danh ngôn của Vitruvius (Sứ mệnh: 8)

Architecture is a science arising out of many other sciences, and adorned with much and varied learning; by the help of which a judgment is formed of those works which are the result of other arts.
Consistency is found in that work whose whole and detail are suitable to the occasion. It arises from circumstance, custom, and nature.
Beauty is produced by the pleasing appearance and good taste of the whole, and by the dimensions of all the parts being duly proportioned to each other.
Nothing requires the architect's care more than the due proportions of buildings.
For an object under the eye will appear very different from the same object placed above it; in an inclosed space, very different from the same in an open space.
