Overmodeled skulls like this one from Jericho were used as part of the people's ancestral cult. The skulls apparently were used as "soul traps" for the spirit of the deceased. Shrines to the Mother Goddess and evidence of massive city walls and permanent domestic architecture were also found at Jericho by 7000 B.C.. Jericho is one of a handful of important sites showing the transition from a wandering way of life to a fully settled, and ultimately, urban civilization.
