Abstract

In religion, as in science, man has attempted to comprehend the links between himself and the world around him. Though his search was limited before the scientific revolution, it was no less meaningful nor less intense than ours is today. Every sacred building had to possess the same ‘functional’ relationship to God as a modern laboratory has to the discipline it serves. The proportions used in the building would epitomise their ideas of the god, and the geometric shapes employed in the building would involve meanings every bit as profound, and stemming from as much thought, as our scientific ideas. The major difference was that they judged truth by consistency rather than by experiment. If we consider the issues involved in siting an atomic power station, and the care we would use to do so, then we may get some idea of what was involved in siting and orienting a sacred building. The way this was done was one of the most powerful tools they possessed for relating man and his world to the gods so that man could understand and where possible control the natural forces around him. In this his purpose is the same as the modern scientist's, though his premises and his methods differed. To illustrate this, I shall discuss the churches in and around the small southern Italian town of Positano
