When did female sculpture begin to use alabaster?

During the period when copper and stone were used together, female sculptures in Mesopotamia began to use alabaster. This kind of stone gives the sculpture a gorgeous feeling. Although the female body in figure 18 does not have a clear meaning of reproductive worship like figure 14 and figure 15, it obviously conveys a certain meaning of maternal worship. The archaeological age of this sculpture is around 5500 BC, and it was unearthed from the cultural site of Samarra in northern Mesopotamia. This work is worth noting not only the materials it uses, but also those prominent big eyes and slightly strange expressions on the head. If we compare them with the lizard head figures unearthed at Elidu site in 4000 BC, we can feel the connection between them.
