Still checking on the "voice" of the Bosnian Pyramid of the Sun

Introduction - It is difficult to imagine a more ill-fated mission than this. After our meting in Trieste, home of our group, we began to travel with uncertain weather, but on our first day in Visoko we immediately encountered a snowstorm. Snow in the Balkans is always abundant and this situation lasted throughout our stay.
It was very difficult to re-register the "voice" of the pyramid that comes from the apex of the Pyramid of the Sun. After reaching the top in the middle of the storm, we were met with an unwelcome surprise: the ultrasonic frequency appeared very faint, almost stentorian.


This time the group of researchers, aimed to trying to solve the mysteries of the Pyramid, had five members: the expedition leader, medical anthropologist, prof.agg. Paolo Debertolis, the scientific assistant, dr. Valeria Hocza and our photographer, mr. Andrea Venturini. Two medical students about to graduate also joined us: Vittoria Barbieri and Giovanni Chiriacò, that next summer will follow the physical examinations on volunteers who will participate in the excavations to assess their functionality before and after the stay of the Ravne tunnels and collaborating to assess whether there is really a change in vital signs in a positive way after a long stay in the vicinity of the megaliths.

For the latter line of research we are still developing a valid protocol that simultaneously possesses the characteristics of simplicity of implementation and reliability.
Unfortunately during our stay, our activities have been confined to areas such as the Ravne tunnel and the KTK tunnels, the latter with any excavation activities suspended, despite the considerable interest for its clear function of rapid transition to the pyramids.

But even in the Ravne tunnels our research attempts didn’t go so well. For a wrong initiative from the workers of  the Foundation, ie the attempt to expand a tunnel over the normal conformation for safety reasons, caused on the contrary a small collapse that has precluded momentarily the entry of the new section of the tunnels. Tunnels just recently explored as far as possible by archaeologist Sara Acconci together with an Italian archaeological caver, Marco.

We therefore had to focus on a careful study on megaliths found in Ravne tunnels achieving somewhat conspicuous results. So far there has never been an organic study done on these stones, but only “light” uncoordinated research. We will publish the preliminary results soon.

But coming back to our adventure on the Pyramid of the Sun in February 2011, we agreed that after we slipped on the ice with our jeep, suffered a severe cold and acquired several bruises by snow falls, the life of the researcher outside of the laboratory is certainly much more interesting than in the company of mice for clinical trials in front of a microscope.

Of course in this case we also risked ending frozen.


Fig. 3 - As we were trying to trace the wind increased, the cloud layer and did not stop snowing

But there were also disappointments. In this case we were looking in spite of the storm, to maintain a certain rigor in the collection of records, but this time the results were much more modest than the last time in January.
For these measurements we tried to follow the instructions developed by our consultant for instrumentation, eng. Battistoni. But it was practically impossible to place the "marker" to delimit the area of observation and write in detail on a sheet constantly wet.


Fig. 4 - This is the situation that presented itself when we reached the top of the pyramid: the medieval town nestled in a picturesque, grim haziness


However, we tried to collect the sound after making sure that the cables were well placed, there was silence and the absence of spurious noises, there were no sources of anomalous transmission (mobile phones switched on), measured the time and place of registration, used three different operators placed in the same working conditions. Everything noted in the register compiled ad hoc.

Fig. 5 - In those moments when the snow decreased we tried to collect as much data as possible 

With regret we have found that while finding ourselves in adverse weather conditions not less than one month ago this time the pyramid did not want to sing for us and launched only soft noises like the sound of a distant train.


Fig. 6 - We tried to alternate ourselves as operators so as not to affect the search results. Here I begin collecting data followed by Giovanni Chiriacò


How to interpret these unsatisfactory results?
First, one can say that the phenomenon is not constant over time, but varies depending on some parameters unknown to us, perhaps the weather, even though there was snow in January 2011 and there was snow in February.


Fig. 7 - Here is Vittoria listening to the "voice" and I try to listen to other points in an enchanted landscape


Secondly, in view of the inconstancy of the emission of ultrasound, there is the need to observe the phenomenon for a longer period of time, without running the risk of operators and tools freezing, with repeated recording, at different hours of the day and under conditions of presence or absence of wind that might electrostatically charging the pyramid in a totally natural way.
All this tells us that you can not store the phenomenon of ultrasonic frequency emitted by the pyramid as an accepted fact, but as something in the making.


Fig. 8 - Despite our obstinacy at some point we had to retreat. With the fog and without seeing anything the risk of putting a foot wrong and injuring ourselves was very high


For making a serious scientific study, we therefore decided to return to the place in spring with the same instrumentation, which had already passed the stage of testing and for demonstrating some operational reliability. We have to repeat listening at different times of the day so as to create a table that generates a trend graph of the phenomenon, its possible rhythmicity or inconstancy.

In the appendix we should be noted we also tried to venture on Sonda Deset (probe n.5), located on the North side of the Pyramid of the Sun at an altitude much lower than the top. In January this location revealed a significant activity in the emission of ultrasounds, but after passing in front of Sonda Ćeteri and Pet (probe excavation number 4 and 5), proved inactive, we were unable to reach it due to difficult climatic conditions encountered, we therefore had to retreat to avoid the risk of  pneumonia.
But we could not notice that, perhaps for the characteristics of the material constitution (conglomerate), the snow took root with great difficulty on the surface of Sonda Pet (probe n.5).



Fig. 9 - We also tried to measure the ultrasonic emission in the various excavation probes of the Pyramid of the Sun, but the ice place just below the snow prevented a rise to the probe n.10,  which previously had proved much more interesting


So we decided that our next mission will be in April 2011, with the hope that at that time the climate would be much more forgiving.
