Summary – SBRG’s research of archaeoacoustic and physical phenomena at ancient sites has developed over a number of years. Our research group uses a practical standard (SBSA) which complements the field of archaeology. Studying archaeoacoustics and natural phenomena over the last five years, it has enabled us to offer an explanation of some of the enigmas of ancient archaeological sites that were not previously possible to explain using other methods. Following our experience, we utilised the same archaeoacoustic methodology to study the town of Alatri in Italy. The present Cathedral of Alatri stands at the highest point of the town underneath which lays a Cyclopean temple. We sought to understand why such a temple was built on top of the hill. Using our SBRG protocol we discovered very strong and significant low vibrations (seismic waves) continuously emitted from the subsoil. Our hypothesis suggests the exposure to such vibrations in the absence of noise could have a significant effect on the psyche of those who came for prayer and meditation, facilitating access into a mystical state. Even though ancient people did not own the same equipment we have today, they would have been aware of the conditions required to achieve such a mystical state, perhaps by simply sensing they were closer to God in a given location. The seismic waves would appear to arise from the geological fault located on the side of the hill where the town has stood since ancient times. The presence of these seismic frequencies would have increased the effect of rituals by enhancing the psyche of the participants due to the influence of these low vibrations on human brain waves. This suggests the builders of this temple had some sort of knowledge of this effect and offers a possible explanation as to why the temple was built in that particular location.
