Imagine an edifice with a facade so extensive that it runs the risk of losing its unity. If, however, it were to have two like towers at its two extremes, its unity would be reconstituted by means of symetry.
When the French wish to describe the dominating attitude of a man, they say that he has the air of a king receiving another king – “l’air d’un roi recevant un autre roi”. What comprises the beauty of a sovereign receiving another soveriegn? It is comprised precisely of the beauty of symetry, in which two equal principles contemplate one another and, in a certain way, augment each other.
In Christianity, the existence of many kings equal in force, glory and power was a precise expression of the principle of symetry.
