Maori Petroglyphs
The ancient Maori Tribes of New Zealand employed the use of Petroglyphs in order to communicate. The carvings found in Maori rock art, depict various human figures, various fish, water vessels, Moa birds, now extinct, and other bird figures, mythological tribal figures, and recurring similar symbols and motifs.
There are hundreds of sights on both the North as well as South Islands which one encounters through travel there. Kakahu Bush is the main area on the South Island where the majority of these petroglyphs are found. A guide at one site claimed the bulk of all ancient Maori rock art is on private lands which the public never sees, or likely yet to be discovered.
The Maori petroglyphs are often small faded simplistic designs upon random rocks, or in some cases elaborate lengthy murals carved upon protected under overhanging limestone outcroppings.
This picture of what is called the Squatter Man, was found in the region of Kaku Bush, on a bit of north facing rock, it is a mysterious recurring symbol or effigy, not only in New Zealand, but also all around the world. Some say it has resemblance to other similar petroglyphs found elsewhere on the planet where the Squatter Man imagery is found on north facing rocks upon mountainous regions, which are protected by other rock barriers, and survived as a result from what may have been an ancient high energy radiation blast. This similarity of imagery and placement ties into the, "Electric Universe Theory", a a hypothetical event which suggests that a plasma discharge occurrence near the South Pole, seen in the skies on a global scale by ancient peoples simultaneously, is the reason for the similar imagery found on worldwide petroglyphs.
There is no way to know for sure, but it is interesting to consider the possibilities. The early development of communication is a conundrum of worlds within worlds which we are still in our advanced technological age unable to truly decipher.
