Rectilinear and Curvilinear architecture
Let us see the logic through which the clergy separated the rectilinear from the curvilinear shapes, to create the architectural systems we mention in the 1st part of the book “Holy Sacramental Journey to Greece” (by author G. Baltoyannis); a logic which had to do with the psychology of the individual. Even to this day we follow the same logic and express ourselves with designs and volumes in the same way. Today however it is difficult to say if our own perception of space is a spontaneous expression or if it comes from the processing of the past.
Nowadays when an artist wants to express “joy” or “sorrow”, he will use the same logic on the canvas, otherwise he will not be understood. Therefore through education we learn to distinguish the things, in order to understand the artist. Of course art nowadays is not bound by rules, based on which the art critic gave his opinion on the work of the artist and which started to be created during the Renaissance. These rules came from the interpretation of the works of art of antiquity. Therefore our opinion is very deeply rooted. Let us now observe the logic of the Ancients.
There was a clear distinction between a straight line and a curved part. When someone wants to express a powerful emotion, like passion, love or anger and has to choose between a straight line and a curved part, he will not choose the rectilinear but the curvilinear; on the contrary, if he wants to express thought, justice, conviction, he will use the rectilinear part.
The reason he would choose the curvilinear would not be because that was forced upon him, ergo it would have been a matter of habit, but because man lives and belongs to the natural environment, where everything is based on curvilinear shapes; he instinctively and spontaneously understands those, without being able to see the process within him, it is namely cthonic.
The straight line occurred from cerebral activity, when man used tools and created structures, which are easier to solve in time. The outcome of said process is also visible outside of man, in the light of day, it is namely celestial.
Therefore, the rectilinear surface is a result of thought and is identified with reason, while the curvilinear always existed in the nature of man. The more a person evolves, the more the straight line dominates in his structures, because, it not only spares him time, it is also more economic.
When then, in a given time, man, reaching some level of intellectual maturity, thinks of structurally expressing his religious needs, he chooses the curve for his passions and the straight line for his thoughts. But because man thought of his own origin, he came to the conclusion that he himself was also the creation of some rational thought, the same way he thinks and creates. Therefore he places this God, his Creator, based on the rectilinear logic, outside of man and above him, to watch and protect him. That is why the ancients sacrificed a white lamb, on a high altar, for the celestial gods.
On the contrary, as far as his passions are concerned, which make him clash with his fellow man, there is also some god responsible. And because it all starts within man, therefore the god of passion lies within man and bellow the earth, since he is not seen. They sacrificed then, to the chthonic gods, digging in the earth, the black lamb.
