Throughout most of architectural history, daylight has been the primary source of light, supplemented by burned fuels. In addition to illumination, daylight has been symbolic of cleanliness, purity, knowledge, and heaven.
Generally speaking, in climates where daylight is plentiful and predictably bright, architects have responded by decreasing opening sizes or using a diffusing medium in the openings (grilles, and translucent or tinted glazing).
To a remarkable degree, past architecture tended to admit light only where it was wanted. Windows and roof openings were given special prominence within the structure. As a result, there were rather great changes in light levels within a building. Usually the presence of openings and correspondingly bright areas signified that a special "event" occurred within that region.
