Look for Rast archaeological site. 
Rast is a little village near Danube, in Dolj, SW Romania.
Eponymus site of the Vinca culture, represented by the beautiful writing figurines. Chronology? 5.500 - 4.800 BC.
One of the first Madonna with Child of the World.

Marija Gimbutas believed that "Madonna from Rast" loves her baby like our mothers love us and that she's transmitting this very very wonderful message with the help of a structures of signs that all European people knew in 5th mill. BC. This structure is a first organized writing.

This is, maybe, the first human writing!
