Prehistoric Civilizations: The Cochno Stone is the most amazing and mysterious archaeological discovery.
The 5000 year old Cochno monument, according to some experts, represents an ancient cosmic map that has been kept secret for decades to protect it from vandalism.
Discovered in 1887 in Scotland, the ancient stone slab measures 13 meters long and 8 meters wide. Ninety percent of the carvings feature intricate petroglyphs, which many researchers believe represent a cosmic map detailing the planets and stars.
After its discovery in 1965, archaeologist Ludovic McLellan Mann decided to bury it under several feet of soil to protect it from further damage and prevent people from adding their own carvings to it.
Archaeologists still have not agreed on exactly what is depicted on the massive tablet. There is no consensus on the meaning of the complex symbols on the tablet's surface, other than it may be a map of heaven and earth. Some have suggested that the tablet is actually a gateway between life and death, symbolizing rebirth!
Some archaeologists believe that the complex drawings of domes, lines, and spiral rings are an ancient form of rock art found in many parts of the world.
According to symbol experts, they date back to the Bronze Age and the early Neolithic, but some examples have been found so far from the Iron Age.
The Cochno Stone map features incredible signs and markings reminiscent of the massive crop circles often attributed to extraterrestrial civilizations and somewhat reminiscent of the Nazca Lines in Peru.
Interestingly, other similar tablets have been found in northern Spain, Mexico, Greece, and India. To this day, the exact content of the stone messages remains a mystery.
