GOTHIC ARCHITECTURE
During many centuries the architects struggled with this problem of constructing a building that was large enough. The Roman tradition taught them how to build heavy stone walls with very small windows lest the walls lose their strength. On the top of this they then placed a heavy stone roof. But in the twelfth century, after the beginning of the Crusades, when the architects had seen the pointed arches of the Mohammedan builders, the western builders discovered a new style which gave them their first chance to make the sort of building which those days of an intense religious life demanded. And then they developed this strange style upon which the Italians bestowed the contemptuous name of “Gothic” or barbaric. They achieved their purpose by inventing a vaulted roof which was supported by “ribs.” But such a roof, if it became too heavy, was apt to break the walls, just as a man of three hundred pounds sitting down upon a child’s chair will force it to collapse. To overcome this difficulty, certain French architects then began to re-enforce the walls with “buttresses” which were merely heavy masses of stone against which the walls could lean while they supported the roof. And to assure the further safety of the roof they supported the ribs of the roof by so-called “flying buttresses,” a very simple method of construction which you will understand at once when you look at our picture.
This new method of construction allowed the introduction of enormous windows. In the twelfth century, glass was still an expensive curiosity, and very few private buildings possessed glass windows. Even the castles of the nobles were without protection and this accounts for the eternal drafts and explains why people of that day wore furs in-doors as well as out.
Fortunately, the art of making coloured glass, with which the ancient people of the Mediterranean had been familiar, had not been entirely lost. There was a revival of stained glass-making and soon the windows of the Gothic churches told the stories of the Holy Book in little bits of brilliantly coloured window-pane, which were caught in a long framework of lead.
Behold, therefore, the new and glorious house of God, filled with an eager multitude, “living” its religion as no people have ever done either before or since! Nothing is considered too good or too costly or too wondrous for this House of God and Home of Man. The sculptors, who since the destruction of the Roman Empire have been out of employment, haltingly return to their noble art. Portals and pillars and buttresses and cornices are all covered with carven images of Our Lord and the blessed Saints. The embroiderers too are set to work to make tapestries for the walls. The jewellers offer their highest art that the shrine of the altar may be worthy of complete adoration. Even the painter does his best. Poor man, he is greatly handicapped by lack of a suitable medium.
And thereby hangs a story.
The Romans of the early Christian period had covered the floors and the walls of their temples and houses with mosaics; pictures made of coloured bits of glass. But this art had been exceedingly difficult. It gave the painter no chance to express all he wanted to say, as all children know who have ever tried to make figures out of coloured blocks of wood. The art of mosaic painting therefore died out during the late Middle Ages except in Russia, where the Byzantine mosaic painters had found a refuge after the fall of Constantinople and continued to ornament the walls of the orthodox churches until the day of the Bolsheviki, when there was an end to the building of churches.
Of course, the mediæval painter could mix his colours with the water of the wet plaster which was put upon the walls of the churches. This method of painting upon “fresh plaster” (which was generally called “fresco” or “fresh” painting) was very popular for many centuries. To-day, it is as rare as the art of painting miniatures in manuscripts and among the hundreds of artists of our modern cities there is perhaps one who can handle this medium successfully. But during the Middle Ages there was no other way and the artists were “fresco” workers for lack of something better. The method however had certain great disadvantages. Very often the plaster came off the walls after only a few years, or dampness spoiled the pictures, just as dampness will spoil the pattern of our wall paper. People tried every imaginable expedient to get away from this plaster background. They tried to mix their colours with wine and vinegar and with honey and with the sticky white of egg, but none of these methods were satisfactory. For more than a thousand years these experiments continued. In painting pictures upon the parchment leaves of manuscripts the mediæval artists were very successful. But when it came to covering large spaces of wood or stone with paint which would stick, they did not succeed very well.
