Principles of Architecture

Introduction

Architecture depends on Order, Arrangement, Eurythmy, Symmetry, Propriety and Economy. Order gives due measure to the members of a work considered separately, and symmetrical agreement to the proportions of the whole. It is an adjustment according to quantity. By this I mean the selection of modules from the members of the work itself and, starting from these individual parts of members, constructing the whole work to correspond. Arrangement includes the putting of things in their proper places and the elegance of effect which is due to adjustments appropriate to the character of the work. Its forms expression is these: ground plan, elevation, and perspective.

- A ground plan is made by the proper successive use of compasses and rule, through which we get outlines for the plane surfaces of buildings.

- An elevation is a picture of the front of a building, set upright and properly drawn in the proportions of the contemplated work.

- Perspective is the method of sketching a front with the sides withdrawing into the background, the lines all meeting in the centre of a circle. All three come of reflection and invention.

Principles of Architecture according to Vitruvius

Refection is careful and laborious thought and watchful attention direct to the agreeable effect of one's plan. Not less also because the foot has the sixth part of a man's height, and also because six times, that is the number six, in that it is completed by the number of feet, determined the heiht of the body, they fixed that number as perfect, observing that the cubit consists of six palms and twenty-four fingers. Hence also the cities of the Greeks seem to have made in a like fashion (just as the cubit is of six palms) six parts of the drachma, the coin which they use, stamped bronze coins like asses, which they call obols; and to have fixed twenty-four quarter obols, called by some dichalcha, by others trichalcha to correspond to the fingers.

Invention, on the other hand, is solving of intricate problems and the discovery of new principles by means of brilliancy and versatility. These are the departments belonging under Arrangement. Eurythmy is beauty and fitness in the adjustments of the members. This is found when the members of a work are of a height suited to their breadth, of a breadth suited to their length, and, in a word, when they all correspond symmetrically.

Symmetry is a proper agreement between the members of the work itself, and relation between the different parts and the whole general scheme, in accordance with a certain part selected as standard. Thus in the human body there is a kind of symmetrical harmony between forearm, foot, palm, finger, and other small parts; and so it is with perfect buildings. In the case of temples, symmetry may be calculated from the thickness of a column, from a triglyph, or even from a module; in the ballista, from the hole, in a ship, from the space between the tholepins, and in ...
