Here are some other observations that I have made on my travels:
The insides of dolmen are often decorated. This makes no sense in some instances as the dolmen was obviously not meant to be occupied (some sound holes are too small for an adult to climb through). I suppose that those who hold with the traditional view that dolmen are tombs may attribute this to religious practices of the time. However, there are two features of the decorations that hint at an electrical use:
Zig-zag mottifs are often found. Even today we associate zig-zags with lightning and electrical phenomena. This design is found at megalithic sites all over the world. Below is a photo of a beautiful dolmen in the Zhane River Valley, Russia, with the pattern clearly visible on the supporting stones. There is also a zig-zag pattern running around the entirety of the inside.
It is interesting to note the design on the front stone (with the sound hole in) which shows the basic structure of a dolmen.
I also noticed that the walls inside this one were bumpy, a sort of dimpled texture, rather like the egg-box panels used in recording studios today. Was this done to increase the surface area of the stone and thus allow more sound waves to be absorbed? Perhaps the decoration serves a practical purpose as well as an aesthetic one.
Below, two photographs of stones at Fourknocks in Ireland displaying the same zig-zag motiff.
Are the lozenges or "diamonds" shown in the photo below, a reference to the function of the quartz and feldspar in the rock?
The Wiki entry on Bryn Celli Ddu reads:
"During the Neolithic period a stone circle and henge stood at the site. An area of burnt material containing a small human bone from the ear, covered with a flat stone, was recovered."
Is this another reference to the importance of sound in these structures? I was interested to see what human ear bones look like and made the astonishing discovered that the cochlea is a spiral structure. Spirals are another common petroglyph on megaliths!
When I first began researching, I was surprised to find there are megalithic sites throughout the entire world. Everywhere from Korea, France, India, Russia. From this alone and the similarities in construction is seems obvious to me that this was at one point a global civilisation - and our history books are WRONG.
The location of these sites was very important. Sites such as Lligwy are constructed over fissures in the rock. I am convinced that these areas are akin to accupuncture points on a human being. If we regard our planet as having a "body", through which energy (or "chi") flows, might there be points at which this energy is stronger and can be easily tapped? The earth itself has been shown to have an electrical charge. Not a strong one, but then piezoelectric power is about amplifying that charge and converting it into something usable. An interesting book to read is David Childress-Hatcher's "Anti-Gravity and the World Grid" which postulates that there are such energy points all over the planet. Interestingly, the pyramid at Giza sits on one.
As Above, So Below
Researcher Andis Kaulins has done some fascinating work regarding the location of megalithic sites. He hypothesises that they are laid out in accordance with various star systems. For example, a cluster of dolmen may represent the constellation of Cassiopeia. This is an interesting article: "Dolmens of the Caucasus Russia Deciphered : Evidence and Megalithic Sites"
Andis has written this book on the subject: "Stars, Stones and Scholars: The Decipherment of the Megaliths as an Ancient Survey of the Earth by Astronomy".
Type of Stone Used
Geology is definitely not my field, but it appears that most megaliths are made of granite. Limestone and sandstone are also popular. The famous "bluestone" granite of Stonehenge contains a high quantity of quartz and feldspar. Though megaliths were built using other types of stone, it seems that they all share the characteristic of containing large amounts of quartz. This is key to their piezoelectric use. It has recently been discovered that some megaliths are also made from petrified wood. Once again, this type of rock contains high levels of quartz.
The Sumerian Connection
Whilst reading Zecharia Sitchin's book The 12th Planet, I came upon this illustration from a Sumerian cylinder seal.
Sitchin describes it thus: "That radioactive materials were known and used to treat certain ailments is certainly suggested by a scene of medical treatment depicted on a cylinder seal dating to the very beginning of Sumerian civilization. It shows, without question, a man lying on a special bed, his face is protected by a mask, and he is being subjected to some kind of radiation.".
What struck me was the similarity between the "special bed" and the basic construct of a dolmen (as illustrated also on the front of the dolmen in the Zhane river valley, pictured above). Perhaps there was a therapeutic use for the electricity produced by stones.
