Of this form the decoration subordinates it the lighting system. The author compares the romantic architecture with the gtica architecture, affirming that while in the romantic cathedral the light penetrates for very small openings in high of the construction, originating a great contrast of light and shade, in the gticas cathedrals, in turn, the more structural walls is not torn by vitrais that introduce in the history of the architecture a luminosity until then unknown. In the gtica architecture, an evolution in the lived deeply constructive techniques could be observed until then. Mascar (2005) affirms that in middle of the century would trace it was invented it for windows, one innovative technique that allowed construction of bigger aesthetic beautiful windows of what until then used in the medieval constructions, thus allowing the emblematic use of the illumination. say. The period is marked by the integration between the architecture and the illumination, having represented values that structuralized that reality and capable to produce signs emblematic of these values. Still according to author, the medieval illumination was capable to create an environment of supreme solemnity, mainly being about the gticos buildings. The characteristic illumination of the gtico is something solemn, where the illumination of spaces was not projected to take care of to the necessities human beings, nor the least the domestic use.
The medieval house was cold, illuminated and badly poor warm for the current parameters. But it is important to verify that in another not measurable dimension, the concept of medieval ambient comfort can be searched: in the configuration of the space. Comfort is the atmosphere with that if the man encircles and in which it lives. As in the kingdom of God, the medieval comfort is intangible, is the proper space bred of which the light is basic part. A medieval building seems finished even so does not possess furniture; it a cathedral or a dormitory is never naked, either bourgeois; the especificidade of the immediate space to the window, destined to the accomplishment of the more demanding visual tasks, beyond if relating with the exterior world, inside creates hiddings place of particular beauty and efficiency of the principles of the gtico project.
