The Ancient Grid Symbol as a Timeless Symbol of Life: The Ways the Fertility Symbol Emerged and Spread around the Plane

Author’s preface: For quite a long time humanity used to live in relative harmony with the environment, as evidenced by the tradition of veneration of spirits and of fruitfulness deity later on, practiced in world's each and every culture. Ancient Europeans associated fruitfulness to lush green grass areas which served as pastures for animals people hunted. On the walls of caves and grottoes ancient people left scratched symbolic images of the fruitfulness deity in the form of a rectangular grid representing these pastures. Gradually, this symbol of life, together with the derived symbol of "rain" in the form of a ladder, spread throughout Eurasia (including Sumer, Elam, Harappa, China) and America.
Even today, several varieties of a that rectangular grid adorn traditional clothes, carpets, ceramics, or pysanky Easter eggs from various peoples of the world. Priests (called shamans) of the Sami and other indigenous peoples of Siberia still draw it on their drums, right next to pasturing deer or horses. So let’s recall this forgotten symbol of fruitfulness to try to return to living in harmony with our environment.
I'd like to express my sincere gratitude to museums, acadrmia edu, scientific foundations and many ordinary people posting in social networks, such as Pinterest, for publishing images of various archaeological findings featuring either rectangular grids or cross symbols.
