Onego Lake Petroglyphs assemble is located on the Besov Nos Cape which is situated at the eastern shore of Onego Lake.
Local inhabitants attributed rock art to the activity of the "evil spirit". This resulted in the name of the area, Besov Nos (Demon's Cape) and in later attempts to neutralize the "devilish pictures" by carving Christian crosses on the figures of the demon and a swan, probably dated back to the 15th Century.
Onego Lake Petroglyphs in contrast to realistic White Sea Petroglyphs are more symbolic and fantastic. They depict the sun and the moon, enigmatic signs and imaginary creatures. The ideas of prehistoric people about the world around are conveyed in some pictures, for example, the sign of the moon has legs, because the moon "goes" over the sky.
