As I have mentioned in my previous blog, it is not the technology, religious beliefs, climate or resources that generate a new style. They are important, no doubt, but as facilitators - the background for a building to designed and built in any specific style. But what creates a new style is an idea - imagination of a creative genius-which may get converted into a poem, a piece of literature, and thence into a painting or sculpture or architecture.
The Gothic Cathedral came into existence as an extension of belief in the greatness of the Church as the house of God. It was not an architect, but a clergyman, Abbot Suger, who came up with the idea of a church with a huge interior space full of light, when he was doing the renovation of the Basilica of Saint-Denis. This is how Gothic Architecture came into being.
It so happened that the pointed arch with its vertical character and a certain freedom in the spans was found most suitable this purpose. It is possible to control the height for a pointed arch for a reasonable variation in spans and its vertical character can create an impact of a large volume of space in the interior, without enlarging the actual area of the Church.
Secondly, to make the Church full of light, the window area had to be enlarged. The flying buttresses came in useful to transfer the load of the roof directly to ground. Already in the Romanesque style the rib & panel construction of roof had
separated the frame & the panel. The Gothic Architects extended this principle to the walls. The columns (like the ribs in the roof) could stand
independently and did not need a wall for support. And thus, the walls absolved of their role of supporting the structure could be made of glass - fulfilling the design objective of a large
transparent surface to fill the interior with light.
But interestingly enough, the walls of Gothic Cathedral did not give a view to the outside. They contained large stained-glass portraits which provided a mosaic of colored light in the interior -
illuminating & mystifying it at the same time.
A concept of a place full of light originated in the harsh, cold climate of northern Europe, where the cold interiors of earlier Romanesque churches with very small windows had a depressing quality. The large amount of light through the stained-glass windows had the effect of uplifting the spirit of the devotees. The predominantly cold climate also dictated that these windows be fixed (not openable), but there was also another aspect of the stained-glass paintings, which may have been incidental, but it greatly enhanced the quality of space as a place of worship.
This is to do with the concentration of the mind of a devotee in the place designed for meditation. Tropical places of worship exclude the external light and view, to achieve dark and cool interior spaces. Temples progressively reduce the amount of light, so much so that when you reach the innermost sanctum where the deity is placed, the place is virtually dark except for a small oil lamp, and a comfortable feeling of coolness. Mosques enclose the exterior, protecting the devotee from the hot winds of the desert, and the only light is coming from the central open court, which is cool in the night. In the day, the prayers are conducted in the dark, windowless hall facing the direction of the prayer.
Both places help the devotee to concentrate on his prayer as there is no external distraction. But if you have windows at eye level, giving a view of the outside, the light coming in from these windows and view result in distraction. The highly acclaimed 'Lotus Temple' in New Delhi fails exactly on this count-you cannot concentrate in the interior hall because of all the light coming in at normal eye level.
The light coming in from a height above, on the other hand, eliminates the distraction and floods the interior with light, which has a mysterious, soothing quality. The Gothic stained-glass windows serve this purpose beautifully. And moreover, the paintings deal in religious subject - accentuating the religious purpose of the place. It is exactly for this reason that the temples are full of sculptures and mosque walls have religious texts inlaid or painted on them.
I used to wonder why the great painters of the day like Michelangelo would spend their efforts in painting the ceilings when it is well-nigh impossible to think that people in a Church would have to bend their heads to look at them - not a very comfortable position to admire a painting. It may have been also due to lack of a clean vertical background in a colonnaded place, but I prefer to think that it is an extension of the thought process detailed above. Once inside a Church, all that you see is a religious text or painting. You may or may not be looking directly at any specific painting - but you know instinctively that they have a religious theme.
The thought process thus precedes any new style in architecture. And even in the Middle Ages-where new thoughts (outside the official religious beliefs) were virtually banned, even within the limited scope of thinking, it is the creative thoughts which led to the birth of a new style.
