Definitive Results of Archaeoacoustic Analysis at Alatri Acropolis, Italy

The town of Alatri is nestled among the hills one hundred miles southeast of Rome, Italy. It features a Cyclopean acropolis on the peak of the hill it sits on. A number of researchers say its origin dates back to a pre-Roman period, but the exact date it was built has not been determined. Our research group has been using archaeoacoustic methodology over the last seven years. Archaeoacoustics has enabled us to offer an explanation for some of the enigmas of ancient archaeological sites that were not previously possible to explain using other methods. Our hypothesis suggests the exposure to particular vibrations in the absence of audible noise could have a significant effect on the psyche of those who came for prayer and meditation, facilitating access into a mystical state. Following our experience, we utilised archaeoacoustic methodology to study Alatri acropolis in Italy from 2013 to 2015 over various missions. The experiment was carried on using three different methods of investigation: digital recording the full audio spectrum, a geologic device for confirming what we found on microphones in infrasound range and TRV technology. We used these methods over different seasons. If digital recording method is well known to every researcher in archaeoacoustics, not so well known is GeoBox SR04S3 Datasheet from Italian firm SARA. The digital accelerometer sensors are a high-performance instrument especially suitable for acquiring signals for seismological and geophysical surveys for recording ambient seismic noise and any other type of vibrations. Compact, reliable and simple, it is fully functional within minutes after deployment. Also not well known is TRV camera (Variable Resonance Imaging Camera, known in Italy as Merlin camera or Defend X system in Japan) coming from industrial use, along with specific annex software, Vibraimage Pro 8.3, is able to process the minimum vibratory differences present in the air resulting from the movement of air molecules visible only instrumentally in the various frames of videos taken by its wide spectrum optical sensor. At the highest point of the town stands the present Cathedral of Alatri which lies on a Cyclopean temple, therefore we sought to understand why such sacred temple was built on top of that hill and not in surrounding other sites. Using our protocols we discovered very strong and significant low vibrations (seismic waves) in that location, not detectable in the surrounding hills, continuously emitted from the subsoil and able to affect brain wave activity. Even though ancient people did not possess 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 site. The seismic waves would appear to arise from the geological fault located on both sides 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.
