Petroglyphs are a relatively common form of prehistoric communication, in the sense that those who drew the petroglyphs knew what they meant, as no doubt did many of their fellow tribesmen who viewed them. The meaning or significance of these images, however, was generally specific to the individual or group that created them. There was never a cross-cultural standardization of symbols and as a result much of the meaning of many petroglyph series has been lost. But has it been entirely lost for all groups of petroglyphs? This article takes a close look at the Pegtymel’ petroglyphs of Northeast Asia with that question in mind.
