Reproduction of an ancient stone carving petroglyph (rock drawing) from the Peterborough petroglyphs in Ontario, Canada, created in high-fire clay.I formed these clay pendants, carved the ancient petroglyph then fired them for several hours in the kiln. I then glazed the pendants and back again in the kiln for another long firing.The pendants average 2" long by 1" wide by 3/16" thick ( 51mm x 25mm x 5mm).**Only one model of each has been made, unique creations, what you see in the photo is what you will receive. Colour will vary in intensity from PC monitor to smartphone screen.**Peterborough Petroglyphs:The Peterborough Petroglyphs are the largest collection of ancient rock carvings (petroglyphs) in all of North America, made up of over 900 images carved into crystalline limestone located near Peterborough in Ontario, Canada.Proclaimed a National Historic Site of Canada in 1976, local indigenous people believe that this is an entrance into the spirit world and that the Spirits actually speak to them from this location. They call it Kinoomaagewaapkong, which translates to "the rocks that teach".The petroglyphs are carved into a single slab of crystalline limestone which is 55 metres long and 30 metres wide. About 300 of the images are decipherable shapes, including humans, shamans, animals, solar symbols, geometric shapes and boats.It is generally believed that the indigenous Algonkian people carved the petroglyphs between 900 and 1400 AD. But rock art is usually impossible to date accurately for lack of any carbon material and dating artefacts or relics found in proximity to the site only reveal information about the last people to be there. They could be thousands of years older than experts allow, if only because the extensive weathering of some of the glyphs implies more than 1,000 years of exposure.
